Boiler on the blink? think help-link! Rather than wasting money keeping water hot on a continuous and ongoing basis (even when you are not at home), the unit heats water as it is needed as the water heats, heated air goes through a redistribution process through the air circulation units this makes the most efficient use of the heating elements for both water heating and home heating. The only thing i would.
