How does it work

EndoTherm improves the heat properties of water

Water is used since the Romans to transfer heat because it is abundant and cheap. However, with sustainability concerns and gas prices rising, it is time to upgrade our water to something more efficient.

EndoTherm makes it easier for water to heat up, for less energy, and give away heat faster.

This improved heat properties have multiple effects on your building heating system

Faster response on heat variation

During the day, a typical building has many heat variations . EndoTherm makes it easier for water to respond on these heat variations.

Turn on heat system later

As the heating-up time is faster due to the improved heating properties, you can turn on your heating system later.

Less residual heat

There is less residual heat left at the end of the day, as EndoTherm dosed water gives the heat away faster. Therefore, the energy is used when you need it.

Improved boiler efficiency

EndoTherm does water enables better heat tranfer between the boiler and the water.

EndoTherm is


independently tested by several institutions

Scientific explanation

EndoTherm reduces hydrogen bonds strength between water molecules

Water are many water molecules that loosely interact with each other via hydrogen bonds.

Heat capacity is lowered

A heat capacity that is lower eneables the water to heat up faster using less energy.

Surface tension will be reduced

Less surface tension means the water has a better connection with the radiators, improving heat transfer from the water to its surroundings.

Less bubbles at the surface

Less bubbles at the surface of the water also improves the connections with the heating system, improving heat transfer from the water to its surroundings.

Smaller bubbles that mix more

Improved mixing enables the water to distribute the energy better through the water, improving heat uptake.

Increased turbulent viscosity

This improves internal mixing of the fluid, as the water is less “sticky”, in turn improving heat transfer in the liquid.
