3.4 Installation in combination with solar collector system (Scandpell)
If the boiler is to be installed in combination with a solar collector system, it is important to
take the return pipe from the storage tank at such a height that the part of the storage tank
where the solar collector element is located is not heated up by the boiler.
Below installation examples are based on the use of solar collector systems from HS Tarm. If using other
solar collector systems the examples might not be useable. Please check the function options for the solar
collector systems of other manufacturers before deciding the final installation.
In order to avoid corrosion in the boiler, a device must be installed that ensures a minimum
return temperature of 55 °C to the boiler from the unit.
3.4.1 Installation with solar storage tank type OS and separate domestic hot water tank
1: TPK/Scandpell
2: Loading unit 55 °C (you could also use a thermostatic 3-way valve and pump – use a balancing valve on the shunt loop.
3: Storage tank type OS (800, 1000 or 1500 liter)
4: Heating circuit pump
5: Hot water tank VBF 85, VBF 100 or VBF 150
6: Thermostat with external sensor bulb
7: Expansion tank (the size should be adapted to the total volume of the system)
8: Safety valve
9: Automatic air vent
10: Solar collector system - Solar package C
The boiler and the solar collector system jointly heat the storage tank.
The central heating runs independently of the boiler and solar collector system.
In cases where the solar collector system generates so much energy that the storage tank is at risk of
overheating. It is important that there is always some kind of idle consumption in the system, e.g. heat leak
radiator in the bath room.
Control unit set up – see 3.2: Solar collector control unit set up – see manual for Solar package C.
