As water in a central heating system passes over the heat exchanger
in the boiler, a small percentage of that water will boil on the hot
metal surfaces. During this boiling a layer of irregular bubbles
forms which eventually join together and act as insulator between
the gas firing and the water within the radiator circuit.

So just where does this wasted heat disappear to?

It doesn't, it just doesn't get into the circulating water
as well as it should do.

If it doesn't get into the water

It does, just not as well when that additive isnt used.
where does it go, then?

Into the water, just not as well so the water doesn't get as hot.


So this product saves how much energy?
