Combinable assembly with insulating shells for easy installation connection of heat pump, buffer tank, hot water tank (via enclosed T-piece) and heating system. Consists of 2 shut-off valves, 2 bypass lines with non-return valve (response pressure 2000 Pa), safety assembly with pressure gauge and connection option for expansion vessel. Installation option for circulation pump, DN 32 (pump not included). Recommended for connecting heat pumps with a heating water flow rate of up to 2.5 m/h and when feeding external energy (e.g. wood/solar) into the series buffer tank (see project planning documents). To reduce pump running times, the additional circulation pump can only be operated with the compressor. In this case, the return sensor included in the scope of delivery must be installed in the existing immersion sleeve and connected. Due to the hydraulic decoupling, the consumer circuit requires a separate circulation pump.
