Version 2: Heat Pump + Sinclair water heater
System consists of accumulation tank for heating system (radiators and underfloor heating); optional solar
heating can be also connected. Domestic hot water (DHW) can be then heated by a separate heater (e.g.
SWH-15/190T or SWH-35/300TL) without solar heating or SWH-35/300TSL with the possibility of solar
heating connection.
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) Small Sinclair heat pump for independent DHW heating either with solar heating or without this.
c) Pump Grundfos for water circulation in radiators (if heating with radiators is installed).
d) 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.
e) Pump Grundfos for water circulation in underfloor heating (if underfloor heating is installed).
f) 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.
