Two-chamber heat accumulators
Two chambers in the heat accumulator allow the storage of water at a temperature exceeding 100°C in atmospheric tanks. This is allowed by special technical solution described below.

Heat accumulators are insulated tanks usually with a vertical axis, which are used to
store thermal energy in the form of hot water at temperatures up to 95°C (130 °C).
The basic benefit of using a heat accumulator in a district heating system is to
balance the load of the heat source with the customers changing energy demand.
With our long track record the construction and design of heat accumulators we offer:
Two chambers in the heat accumulator allow the storage of water at a temperature exceeding 100°C in atmospheric tanks. This is allowed by special technical solution described below.
To date, we have built over 90 heat accumulators with a total volume exceeding 1,000,000 m3 of water, of which 5 pieces are two-chamber batteries.
At 30.01.2019, Rodoverken Sp. z o.o. began prefabricating the equipment of 3 heat accumulators built in Sweden.
