Indoor module NIBE™ EVP 500Designed for houses / properties with waterborne heating

NIBE EVP 500

The indoor module consists of a pressure vessel, two immer-sion heaters, docking pump and intelligent control, and is optimally adapted to suit docking with NIBE’s air/water heat pumps. The total boiler water volume is 500 litres.

Hot water heating occurs via a cam pipe coil. The low inter-nal volume and high circulation rate of the water in the coil prevents bacterial growth. In the event of a domestic water flow greater than 12 l/min, supplementing with a core wa-ter heater is recommended.

The immersion heaters have a max output of 18 kW wit-hoption of setting lower outputs. The supplied output is 9 kW.

System description

The indoor module and heat pump work optimally towards a heat distribution system of up to 55/45 °C at dimensio-ned outdoor temperature. At higher flow line temperatures (maximum 65 °C) heat pump operation can be limited. If the heat pump operation is limited the installation only works with the addition. The heat pump starts when temperatures permit operation again. For further information about system limitation, see the heat pump manual.

DockingNIBE EVP 500 can be installed in several different ways. The requisite safety equipment must be installed in accordance with current regula-tions for all docked options. See www.nibe.eu for docking options.

EVP 500 must be docked to an outdoor air heat pump with a maxi-mum output of 15 kW.Pipe connection to NIBE outdoor air heat pump Connect the heat pump’s supply (70) to the EVP’s ”Supply HP.” (76). The heat pump’s return line (71) must be connected to the EVP’s ”Return line HP” (75). The heat pump’s supplied particle filter must be installed on the heat pump’s return line.
