Backer BFU - Flow heater unit - supplementary heater
This supplementary heater is generally used as a complement to a heat pump but can also be used together with other heating appliances. The heater will turn on when the heat pump capacity is insufficient, for example during cold winter days. A supplementary heater also adds extra security if the heat pump malfunctions.
