EndoTherm™ is an energy saving additive which can be installed in any wet central heating system.

EndoTherm™ has been independently proven to use up to 15% less fuel to maintain the same temperatures as water alone.

One 500ml bottle of EndoTherm™ is sufficient to dose the average domestic system of up to 12 radiators, for systems up to 24 radiators use 2 bottles. For commercial systems the recommended dosage is 1 litre per 100 litres of system volume.

Easily installed, EndoTherm™ can be added to a system using a feed and expansion tank or via a partially drained radiator.
