           THERMODYNETICS' REPORTS NET SALES FOR CONTINUING OPERATIONS
                  NET SALES INCREASED 38% IN THE THIRD QUARTER
                       AND 17% FOR THE LATEST NINE MONTHS

WINDSOR, CT - Wednesday, February 15, 2006 - Thermodynetics, Inc. (TDYT: OTCBB)

                  Net sales from continuing operations for the three months
ended December 31, 2005 increased by $1,244,000, or 38% over the prior year. For
the nine month period, net sales were $13.6 million, or 17% above the period
ended December 31, 2004. Expectations for the March 2006 fiscal year are for
sales to exceed $18 million.

         The increase in year to date sales is due largely to the continued
strong performance in the domestic housing market and air conditioning for
marine applications. Our marketing of heat exchangers containing high efficiency
special purpose enhanced surface titanium tubing for the swimming pool and spa
heat pump industry has received an exceptionally strong response.

         Cost of sales increased for both the three and nine month periods of
the current year, compared to the same periods in the prior year. The cost of
metals, principally copper, copper alloys and titanium has risen sharply to
their highest levels in the past six years; although the effects of metal cost
changes are shared to a large degree with customers, the impact is a net
reduction of gross margin. Further, the pass through of a portion of such
material price increases can only be periodically adjusted. Effective with the
new calendar year, price increases have been instituted and improvement in gross
margin is expected.

         The increase in selling, general and administrative expenses over the
prior year was 10% and 11% for the three and nine month periods, respectively.
Personnel were added in customer service, engineering and other support
functions to both support the additional sales base and assist in the
development of future products. The Company plans on further additions to its
marketing and engineering staff during the balance of the fiscal year and into
fiscal 2007 to support new products and markets.
