NEWS   RELEASE                                            OTCBB:  TDYT
                                                          February 13, 2007


     THERMODYNETICS REPORTS RECORD SALES AND A 109% INCREASE IN INCOME FROM
         CONTINUING OPERATIONS IN THE 3 MONTHS ENDED DECEMBER 31, 2006

WINDSOR, CT - Tuesday, February 13, 2007 - Thermodynetics, Inc. (TDYT: OTCBB)

          The Company  generated  record net sales of $5,767,000 and $17,312,000
for the three and nine month periods ended December 31, 2006  representing a 27%
increase over both prior year periods.  Comparing the periods ended December 31,
2006 and 2005, the three month 27% revenue increase  generated a 17% increase in
gross  profit.  For the nine  months,  these  comparisons  yielded a 27% revenue
increase and a 9% gross profit increase.

          Income from continuing  operations after income tax provisions for the
current  quarter was $370,000  compared to $177,000 for the prior year period (a
109%  increase) and for the nine month period was $534,000  compared to $515,000
(a 4% increase) for the prior year  (excluding  the gain on the sale of Turbotec
equity in May 2006).

          The majority of the revenue increase resulted from the pass through of
material  cost  increases  to  customers  while unit  shipments  also  increased
slightly  from the prior  year,  coupled  with a shift in  product  mix  towards
larger, higher priced coils. The overall demand for  condenser/evaporator  coils
has remained high despite the weakening in  residential  construction.  Concerns
over rising costs and the future  availability  of energy sources have helped to
create market  opportunities for "green" heating and cooling  products,  such as
geothermal technology,  and other high efficiency systems that use the Company's
heat  exchangers.  Enhanced surface titanium tubing for the swimming pool heater
market continues to exhibit overall growth.

          Cost of sales  weakened  to 78% and 79% of net  sales  in the  current
quarter and nine  months of this  fiscal year  compared to 76% and 75% in fiscal
2006. The cost of copper rose sharply between March and May 2006,  peaking above
$4.00 per pound,  retreating  to close at $2.85 per pound at the end of December
2006; the cost of nickel continues its rise to record levels. The net impact has
been a significant reduction in gross margin from the prior year.

          The increase in metal prices  resulted in higher  inventory  values as
higher priced tubing was purchased to satisfy  customer  demand and the shift to
larger capacity coils requiring more expensive tubing;  increased  quantities of
titanium  tubing  (principally  used in swimming pool heater  applications)  and
overall  higher  levels  of coil and  surface  enhanced  tubing  production  all
contributed  to the  increase in  inventory  levels.  The  Company has  recently
instituted  price  increases  and pricing  formula  changes which is expected to
improve gross profit margins.

          Selling,  general and administrative  costs increased because of added
corporate  governance  costs and  related  expenses  incurred as a result of the
public offering of Turbotec's  securities in London.  The expansion of the sales
base was augmented by staff additions in sales and engineering;  the full effect
of these expenses are reflected in the current fiscal year results.

          In May 2006 the Company completed the sale of a 43.68% interest in its
Turbotec subsidiary through a public offering raising a net of $6.8 million.

          In  November  2006,  the  Company  settled  a  dispute   resulting  in
extinguishing notes







payable and accrued interest aggregating $606,000 relating to the acquisition of
Vulcan.

          In December  2006 the Company  refinanced  a mortgage for $900,000 and
also received a two year revolving line of credit with a maximum availability of
$1,100,000.  A separate  line of credit of $500,000 to fund capital  expenditure
programs  has  also  been  established  for  Turbotec.  The  Company  had  a net
consolidated  cash  position of $946,000 at December 31, 2006 over and above the
credit facilities.
