EndoTherm is an energy-saving additive that can be used to reduce space heating energy consumption in any existing or new hydronic (water-based) heating system regardless of fuel source.


EndoTherm is added to the bulk heating system fluid at a dosage of 1:100, or 1% of system volume, and remains active in the system for at least 10 years as long as the dosage ratio is maintained.

EndoTherm is added to the circulating heating water with no engineering works required to the system.

EndoTherm uses a proprietary formulation of self-organising molecules to interact with the heating system fluid in a way that changes with temperature, to significantly improve water’s thermal-dynamic response characteristics. This allows heating systems to better respond to changing conditions, deliver useful heat to the locations it is needed at the times it is needed, and reduce excessive wasteful heating thereby saving energy.

EndoTherm has been extensively independently tested in both lab based and pilot projects with savings up to 15%
