Endo Therm

How it works

EndoTherm when added to the bulk water in your heating system will greatly reduce the surface tension of the water. This changes the way bubbles form when the water is heated. No longer will the bubbles be large, lazy and obstructive as they flow through the system; instead they will be small, speedy and offer no obstruction accelerating the heat transfer from the boiler tube into the circulating liquid. The boiler does not need to work as hard to achieve and maintain the required temperature.
