Energy saving additive for
commercial or domestic heating systems.
Save up to 15% on heating bills.
EndoTherm is a unique, award winning energy saving additive that is suitable for any wet heating system. EndoTherm has been independently proven to save up to 15% on heating bills.
Due to the surface tension of fluid and imperfections in materials inside heating systems optimal thermal contact is not made.
When dosed EndoTherm™ stably changes the surface tension of the fluid by over 60% whilst remaining non-corrosive.
This increases the thermal contact which improves heat transfer rate and heating efficiency.
Resulting in rooms reaching determined temperature quicker and staying warmer for longer.
Return water temperature is lower which allows boilers to condensate more efficiently and recover more latent heat.
Less fuel is consumed to maintain thermostatically set temperature.
