Domestic H&V Product of the Year – Sustainability and Safety

EndoTherm is an energy-saving central heating additive that has been independently proven to save homeowners up to 15% on their heating bills.

The product can be added to any wet-based central heating system, where it mixes with the water and changes the physical properties of the fluid – properties that change include specific heat capacity, thermal conductivity and surface tension.

This change in physical properties means the water will heat up quicker, or with less energy, and stay warmer for longer, ultimately meaning the boiler will have to do less work to maintain the desired temperature within a property.

It has also been proven to have slight inhibitor properties and to act as a silencer, reducing the noise of heating systems. EndoTherm is easy to install, with an installation kit and video available for installers, and once it is in a system it does not require constant maintenance or optimisation.

It will continue to make savings for as long as it is in the heating system. EndoTherm reduces use by up to 15% (under test conditions at Enertek International) with real-life examples in excess of this figure.
