Electric Immersion Backup Heating

NIBE VPA and VPAS with Electric Immersion Backup Heating With Air Source Heat Pumps and Ground Source Heat Pumps there is a need for backup heating to bring the temperatures of the hot water up to 60 degrees. Heat pumps can output temperatures this high, but it is often more efficient to boost the hot water to the required level rather than run the heat pump for longer. Overview The water heater is made up of a hot water tank, encased by a double jacket of sheet steel. The hot water tank is fitted with copper or enamel corrosion protection on the inside. See table. The water heaters are designed and approved to meet current pressure vessel standards. Due to the polyurethane foam insulation the water heater provides excellent thermal insulation. If necessary VPA enables the use of an immersion heater for sensor controlled hot water heating. The cold water supply line must be fitted with safety equipment in accordance with current standards. If the water heaters are heated to more than 65 °C, a mixing valve must be fitted. The highest permitted temperature is 100 °C.
