Welcome to accumulatortanks.co.uk

Akvaterm accumulator tanks (thermal stores) are the answer to all your renewable energy heating and hot water needs.

For domestic and commercial application, the accumulator tank, or thermal store, enables the highest level of efficiency and flexibility in water based heating systems.

The Akvaterm accumulator tanks we supply are made in Finland and are highly insulated thermal storage vessels ranging in standard sizes from 300 to 5000 litres capacity filled with the primary water of the heating system. Tanks up to 10,000 litres can be made to order. Their function is to collect and store heat energy from any source and to allow flexible use of the heat energy, either directly for space heating or via an internal heat exchanger for domestic hot water (DHW).

An accumulator tank is the answer for all micro-generation renewable sources. Solar thermal, biomass, wind turbine and heat pump sources of energy can all be connected to the thermal store and if the energy is not needed at the time of generation the tank will store it for later use.

The accumulator tank is especially suitable as a thermal store in log boiler or stove systems. Log boilers need to be fired at high temperature in order to achieve high efficiency and should not be banked down. The accumulator tank is used to store the heat from at least one firing of a fully loaded log chamber, allowing use of the heat as required after the boiler has completed its cycle. A 'loading' or 'charging' unit (such as the Laddomat 21) is used to maintain a high return temperature to the boiler and to 'charge' the accumulator tank from the top downwards with high temperature water, thus creating layering or 'stratification'. Hot water for heating and DHW is then available soon after lighting the boiler.

Peter de la Haye Engineering have supplied and advised on Akvaterm and Termoventiler products since 2005 and have extensive experience in biomass boiler supply and installation. We are UK agents for Veto wood chip and log boilers and suppliers in Scotland of Scandtec log and pellet boilers from Denmark.
