ES Buffer tanks
Well insulated A-class buffer tanks for modern heating systems
Using a buffer tank with a heat pump increases the savings and reduces the load on the heat pump. In order for the heat pump to function optimally, sufficient water must flow through the heat exchanger. The buffet tank reduces the use of electrical additives, which provides additional energy savings. With the help of the buffer tank, the heat pump always operates under optimal conditions, regardless of the building’s thermal load.
More even heat
The heat pumps alternately heat the heating system or tap hot water. The buffer tank is responsible for distributing heat to the heating system while the heat pump produces hot tap water if it thus maintains the indoor air temperature.
Reduces the crushing of radiators
With a buffer tank installed, so-called radiator clicks are reduced. When the temperature of the heating system changes rapidly, clicks from the radiators can be heard. This can be avoided by using a buffer tank. The buffer tank balances the temperature fluctuations in the heating system, thereby minimizing the risk of clicking noise in the radiators.
Preheating hot water
Two of the ES buffer tanks have pre-installed hot water loops. When the buffer tank is connected to an ES air / water heat pump, the tap water can be preheated through the buffer tank loop. In this way, the hot water can also be almost completely heated with a heat pump and, if necessary, an electric heater can be used to achieve the sufficient hot water temperature.
Can be combined with an oil pan – or completely replace the oil pan
Three models have an R50 connection and together with, for example, an air / water heat pump can completely replace the boiler. If you want to keep the oil boiler, you can very easily connect both the air / water heat pump and the oil boiler to the tank. In this case, the oil boiler is only used to balance the peak on the coldest days and the heat pump produces most of the building’s annual thermal energy.
