Akvaterm are from Finland, and it get’s cold there…

So they design high performance heat stores to maintain water temperatures for heating Finnish homes.

If it’s good enough for the Finns, then it’s easily the option we recommend when choosing a wood heating system.

An Akvaterm tank, in isolation, should lose less than 2 degrees of heat per day which is very impressive – this is due to the 100mm thick polyurethane insulation around the tank and the windshielding outer covering.

They’re tough too, lasting a lifetime (well 50 years at least)

Connect an Akvaterm heat store to an Atmos Wood boiler for a highly efficient and powerful wood heating system using sustainable fuel.
