WINDSOR, CT -- (MARKET WIRE) -- 02/13/07 -- Thermodynetics, Inc. (OTCBB: TDYT)

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.
