Version 3: Heat Pump with two Separate tanks
System consists of accumulation tank for heating system without the possibility of connecting to a solar
heating connected with DHW tank with or without the possibility of connecting to a solar water heating.
a) Simple buffer tank for heat pump for heating water circuit with the volume of 400, 500, 600L in PU foam
insulation - very compact (we will deliver). The possibility to connect a solar exchanger.
b) Separate DHW tank (supplier not known at this moment). Tank will have a capacity of 200 and 300 liters
with the possibility of solar exchanger.
c) 2 pcs of 3-way valve for switching between DHW tank and tank for heating circuit. ESBE series VRG
131/132 DN size of connection will be specified later.
d) Electronic control of 3-way valves for tank switching. ESBE series 641 (operation time 30 seconds).
e) Pump Grundfos for water circulation in radiators (if heating with radiators is installed).
f) 3-way valve for equitherm regulation of water temperature in radiators (if radiators are installed): ESBE
series VRG 131/132 DN size of connection will be specified later.
g) Pump Grundfos for water circulation in underfloor heating (if underfloor heating is installed).
h) 3-way valve for equitherm regulation of water temperature in underfloor heating (if underfloor heating is
installed). ESBE series VRG 131/132 DN size of connection will be specified later.
3-way valves for equitherm regulation of water temperature in radiators and in underfloor heating will be
controlled exclusively by electronic control of the type: ESBE series 671 (operation time 240 seconds).
This configuration can be used also for cooling mode. Different types of fan coils can be used as cooling
units.
