Akva Solar thermal stores are for installations incorporating solar thermal heating. We usually recommend the Solar Plus version which has twin solar coils already fitted in the tank, a solar baffle to reduce mixing, and twin domestic hot water coils.
Akvaterm AkvaGeo thermal stores are designed to be used with heat pumps and allow the heat pump to run at high efficiency for longer. Also available as solar and solar plus versions which are ideal for adding in other sources of heat.
The Akva Standard thermal stores are perfect for installations which do not incorporate solar thermal heating. Good for use with a large boiler stove or a log gasification boiler, and available up to volumes of 10,000 lt.
