AKVATERM Accumulator Tanks

Hot water is a basic prerequisite for practical and comfortable living. Akvaterm represents modern ecologic heating technology enabling the most efficient production, storage and distribution of heat required for pleasant living conditions. Akvaterm, a Finish based company, is one of Europe’s finest designers and manufacturers of accumulator tanks.

The hot water tank hugely influences the performance of a heating system. Water has a high heat retention capacity, so in order to maximize on this potential the choice of tank needs careful consideration. The connection of an Akvaterm accumulator tank significantly raises the efficiency of the heating system, lowers energy costs and reduces environmental emissions.

The Akvaterm accumulator tank is independent of the heating system or energy source and can therefore be used alongside solar, biomass, wind, geothermal, oil, gas, electric or combination heating systems.

The capacities of the standard Akvaterm hot water tank models range from 300 litres to 5000 litres. Akvaterm also produces renovation accumulator tanks for upgrade and renovation projects as well as special accumulator tanks whose capacity, units and hot water coils are manufactured according to the customer’s specific requirements.
