Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	NOTE 1 - ORGANIZATION AND BUSINESS The United States Diesel-Heating Oil Fund, LP (“UHN”), prior to August 1, 2012, the United States Heating Oil Fund, LP was organized as a limited partnership under the laws of the state of Delaware on April 13, 2007. UHN is a commodity pool that issues limited partnership shares (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, UHN’s shares traded on the American Stock Exchange (the “AMEX”). UHN will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Second Amended and Restated Agreement of Limited Partnership dated as of March 1, 2013 (the “LP Agreement”). The investment objective of UHN is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of diesel-heating oil (also known as No. 2 fuel oil) for delivery to the New York harbor, as measured by the daily changes in the price of the futures contract for diesel-heating oil traded on the New York Mercantile Exchange (the “NYMEX”) that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire (the “Benchmark Futures Contract”), less UHN’s expenses. It is not the intent of UHN to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of heating oil or any particular futures contract based on heating oil. It is not the intent of UHN to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. United States Commodity Funds LLC (“USCF”), the general partner of UHN, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts (as defined below) and Other Diesel-Heating Oil-Related Investments (as defined below). UHN accomplishes its objective through investments in futures contracts for diesel-heating oil, crude oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and Other Diesel-Heating Oil-Related Investments such as cash-settled options on Futures Contracts, forward contracts for diesel-heating oil and over-the-counter (“OTC”) transactions that are based on the price of diesel-heating oil, crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Diesel-Heating Oil-Related Investments”). As of December 31, 2015, UHN held 66 UHN commenced investment operations on April 9, 2008 and has a fiscal year ending on December 31. USCF is responsible for the management of UHN. USCF is a member of the National Futures Association (the “NFA”) and became registered as a commodity pool operator registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005 and a swaps firm on August 8, 2013. USCF is also the general partner of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”) and the United States Gasoline Fund, LP (“UGA”), which listed their limited partnership shares on the AMEX under the ticker symbols ”USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007 and “UGA” on February 26, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’s, USL’s and UGA’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“DNO”), the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”) and the United States Agriculture Index Fund (“USAG”), each a series of the United States Commodity Index Funds Trust. USCI, CPER, and USAG listed their shares on the NYSE Arca under the ticker symbol “USCI” on August 10, 2010, “CPER” on November 15, 2011 and “USAG” on April 13, 2012, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” UHN issues shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 50,000 From July 1, 2011 through December 31, 2015 (and continuing through at least April 30, 2016), the applicable transaction fee paid by Authorized Participants is $ 350 1,000 In April 2008, UHN initially registered 10,000,000 50.00 200,000 10,000,000 60,000,000

Summary Of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. UHN is an investment company and follows the accounting and reporting guidance in FASB Topic 946. Commodity futures contracts, forward contracts, physical commodities, and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. UHN earns income on funds held at the custodian or futures commission merchant (“FCM”) at prevailing market rates earned on such investments. Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis. UHN is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return. In accordance with GAAP, UHN is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. UHN files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UHN is not subject to income tax return examinations by major taxing authorities for years before 2012. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in UHN recording a tax liability that reduces net assets. However, UHN’s conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. UHN recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. No interest expense or penalties have been recognized as of and for the year ended December 31, 2015. Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 UHN receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in UHN’s statements of financial condition as receivable for shares sold, and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed. Authorized Participants pay UHN a fee of $ 350 Profit or loss shall be allocated among the partners of UHN in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement. UHN’s per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. UHN uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange. Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. There were no shares held by USCF at December 31, 2015. Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UHN. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted. Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less. Certain amounts in the accompanying financial statements were reclassified to conform to the current presentation. The preparation of financial statements in conformity with GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.

USCF also pays the fees of BBH&Co. for its services under such agreement and such fees are determined by the parties from time to time. Currently, USCF pays BBH&Co. for its services, in the foregoing capacities, a minimum amount of $ 75,000 20,000 0.06 500 0.0465 500 1 0.035 1 75,000 7 15 Brokerage and Futures Commission Merchant Agreements On October 8, 2013, UHN entered into a brokerage agreement with RBC Capital Markets, LLC (“RBC Capital” or “RBC”) to serve as UHN’s FCM, effective October 10, 2013. The agreement with RBC requires it to provide services to UHN in connection with the purchase and sale of Futures Contracts and Other Diesel-Heating Oil-Related Investments that may be purchased and sold by or through RBC Capital for UHN’s account. In accordance with the agreement, RBC Capital charges UHN commissions of approximately $ 7 15 For the Year Ended For the Year Ended For the Year Ended December 31, 2015 December 31, 2014 December 31, 2013 Total commissions accrued to brokers $ 5,610 $ 2,837 $ 4,010 Total commissions as annualized percentage of average total net assets 0.12 % 0.07 % 0.06 % Commissions accrued as a result of rebalancing $ 5,436 $ 2,755 $ 3,969 Percentage of commissions accrued as a result of rebalancing 96.90 % 97.11 % 98.98 % Commissions accrued as a result of creation and redemption activity $ 174 $ 82 $ 41 Percentage of commissions accrued as a result of creation and redemption activity 3.10 % 2.89 % 1.02 % The increase in UHNs total commissions accrued to brokers was primarily a result of increased creation and redemption activity during the year ended December 31, 2015, as compared to the year ended December 31, 2014. UHN’s total commissions accrued to brokers for the year ended December 31, 2014, was similar compared to the year ended December 31, 2013, as measured as an annualized percentage of average total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters. NYMEX Licensing Agreement UHN and the NYMEX entered into a licensing agreement on April 10, 2006, as amended on October 20, 2011, whereby UHN was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks.

Financial Instruments, Off-Balance Sheet Risks and Contingencies	NOTE 5 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES UHN engages in the trading of futures contracts and options on futures contracts (collectively, “derivatives”). UHN is exposed to both market risk, which is the risk arising from changes in the market value of the contracts, and credit risk, which is the risk of failure by another party to perform according to the terms of a contract. UHN may enter into futures contracts and options on futures contracts to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Cleared swaps are OTC agreements that are eligible to be cleared by a clearinghouse, e.g., ICE Clear Europe, but which are not traded on an exchange. A cleared swap is created when the parties to an off-exchange OTC swap transaction agree to extinguish their OTC swap and replace it with a cleared swap. Cleared swaps are intended to provide the efficiencies and benefits that centralized clearing on an exchange offers to traders of futures contracts, including credit risk intermediation and the ability to offset positions initiated with different counterparties. The purchase and sale of futures contracts and options on futures contracts require margin deposits with an FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM’s proprietary activities. Futures contracts, options on futures contracts involve, to varying degrees, elements of market risk (specifically commodity price risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure UHN has in the particular classes of instruments. Additional risks associated with the use of futures contracts are an imperfect correlation between movements in the price of the futures contracts and the market value of the underlying securities and the possibility of an illiquid market for a futures contract. Buying and selling options on futures contracts exposes investors to the risks of purchasing or selling futures contracts. All of the Futures Contracts held by UHN through December 31, 2015 were exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with OTC swaps since, in OTC swaps, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if UHN were to enter into non-exchange traded contracts it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. UHN has credit risk under its futures contracts since the sole counterparty to all domestic and foreign futures contracts is the clearinghouse for the exchange on which the relevant contracts are traded. In addition, UHN bears the risk of financial failure by the clearing broker. UHN’s cash and other property, such as Treasuries, deposited with an FCM are considered commingled with all other customer funds, subject to the FCM’s segregation requirements. In the event of an FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited. The insolvency of an FCM could result in the complete loss of UHN’s assets posted with that FCM; however, the majority of UHN’s assets are held in investments in Treasuries, cash and/or cash equivalents with UHN’s custodian and would not be impacted by the insolvency of an FCM. The failure or insolvency of UHN’s custodian, however, could result in a substantial loss of UHN’s assets. USCF invests a portion of UHN’s cash in money market funds that seek to maintain a stable per share NAV. UHN is exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2015 and December 31, 2014, UHN held investments in money market funds in the amounts of $ 600,000 1,801,936 2,322,704 1,398,537 For derivatives, risks arise from changes in the market value of the contracts. Theoretically, UHN is exposed to market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short. As both a buyer and a seller of options, UHN pays or receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option. UHN’s policy is to continuously monitor its exposure to market and counterparty risk through the use of a variety of financial, position and credit exposure reporting controls and procedures. In addition, UHN has a policy of requiring review of the credit standing of each broker or counterparty with which it conducts business. The financial instruments held by UHN are reported in its statements of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturity.

Fair Value Of Financial Instruments [Abstract]
Fair Value of Financial Instruments	NOTE 8 - FAIR VALUE OF FINANCIAL INSTRUMENTS UHN values its investments in accordance with Accounting Standards Codification 820 – Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The changes to past practice resulting from the application of ASC 820 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurement. ASC 820 establishes a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of UHN (observable inputs) and (2) UHN’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the ASC 820 hierarchy are as follows: Level I – Quoted prices (unadjusted) in active markets for identical Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available. In some instances, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety. At December 31, 2015 Total Level I Level II Level III Short-Term Investments $ 1,599,825 $ 1,599,825 $ — $ — Exchange-Traded Futures Contracts United States Contracts (37,846) (37,846) — — During the year ended December 31, 2015, there were no transfers between Level I and Level II.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2015
Summary Of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. UHN is an investment company and follows the accounting and reporting guidance in FASB Topic 946.
Revenue Recognition	Revenue Recognition Commodity futures contracts, forward contracts, physical commodities, and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. UHN earns income on funds held at the custodian or futures commission merchant (“FCM”) at prevailing market rates earned on such investments.
Brokerage Commissions	Brokerage Commissions Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.
Income Taxes	Income Taxes UHN is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return. In accordance with GAAP, UHN is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. UHN files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UHN is not subject to income tax return examinations by major taxing authorities for years before 2012. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in UHN recording a tax liability that reduces net assets. However, UHN’s conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. UHN recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. No interest expense or penalties have been recognized as of and for the year ended December 31, 2015.
Creations and Redemptions	Creations and Redemptions Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 UHN receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in UHN’s statements of financial condition as receivable for shares sold, and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed. Authorized Participants pay UHN a fee of $ 350
Partnership Capital and Allocation of Partnership Income and Losses	Partnership Capital and Allocation of Partnership Income and Losses Profit or loss shall be allocated among the partners of UHN in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.
Calculation of Per Unit Net Asset Value	Calculation of Per Share Net Asset Value (“NAV”) UHN’s per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. UHN uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.
Net Income (Loss) Per Share	Net Income (Loss) Per Share Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. There were no shares held by USCF at December 31, 2015.
Offering Costs	Offering Costs Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UHN. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted.
Cash Equivalents	Cash Equivalents Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less.
Reclassification	Reclassification Certain amounts in the accompanying financial statements were reclassified to conform to the current presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.
