The Ecowatts Thermal Energy Cell (TEC) is an Directory:Electrolysis based energy cell that converts electrical power into heat at an efficiency significantly greater than that of a conventional immersion heater. This is achieved without the consumption of additional fossil fuels.

It is claimed in the media that the system has been independently, scientifically verified to produce 1.5 to 2 times as much energy out as was put in.

Expected in the market by 2010.

How it Works

Image:EcoWatts Thermal Electric Cell schematic 375.jpg

The system involves passing an electrical current through a mixture of water, potassium carbonate (otherwise known as potash) and a secret liquid catalyst, based on chrome. This creates a reaction that is claimed to release an incredible amount of energy compared to that put in. If the reaction takes place in a unit surrounded by water, the liquid heats up, which could form the basis for a household heating system.

Ecowatts' researchers believe it taps into a previously unrecognised source of energy, stored at a sub-atomic level within the hydrogen atoms in water.


Ecowatts estimates that the device will cost between £1,500 and £2,000, which is comparable to the price of traditional systems.


According to the Daily Mail, a UK newspaper: "Sceptical independent scientists carried out their own tests and discovered that the 12in x 2in tube really does produce far more heat energy than the electrical energy put in."

In this piece Jim Lyonsa business development mananger at the University of York, is reported to have independently evaluated the system. He is quoted as saying,

The same source reports that sustainable energy expert Professor Saffa Riffatof Nottingham University, has also led a team investigating the system. He is quoted as saying: 'The concept is very interesting and it could be a major breakthrough, but more tests are required. We will be doing further checks.' [

In 2003 Dr Jason Riley, then of Bristol University, was reported to have found energy gain factors of between three and 26. A UK newspaper, the Daily Telegraph, quoted a report written by Dr Riley as concluding: "Using the apparatus supplied by Gardner Watts and the procedure of analysis suggested by the company, there appears to be an energy gain in the system." The article also attributed a cautionary comment to Dr Riley: “There’s no doubt that there was a heat rise but I’d like to see a more thorough investigation of the electrical energy supplied into the cell.“ Telegraph May 18, 2003)


Quoting from

The TEC is silent unlike air source heat pumps.

Significantly reduces the cost of heating with electricity.

Has the benefit of economically providing continuous heat generation.

Saves carbon emissions through increased energy output with no additional carbon dioxide generation.

Removes the need for unfriendly night time storage.

Usable with other sustainable and renewable energy sources such as photovoltaic, fuel cells, wind power, Stirling cycle engines, and tidal and hydro power etc.

Is conventionally installed and can directly replace gas based heating system.

Is an economic substitute for heating with gas or oil.

The TEC, compared with ground source heat pumps, does not require a bore hole or a large area of land.
