The water heater may be connected to the household water supply system without
a pressure-reducing valve provided the supply mains pressure is less than 0.5
MPa.
In case of the mains pressure exceeding 0.5 MPa, a pressure-reducing valve must
be installed to ensure that the pressure on the supply side of the heater does not
rise above the nominal value.
Key:
1 – Return safety valve
2 – Test valve
3 – Non-return valve
4 – Pressure-reducing valve
5 – Stop valve
6 – Test unit
7 – Funnel outlet to the drain
8 – Drain valve
H – Cold water
T – Hot water
CONNECTION TO ALTERNATIVE SOURCES OF HEATING
The heaters enable the water for sanitary use to be heated by alternative sources
of energy (e.g. central heating, solar power, ...) by installing one or two heat
exchangers.
Additionally, a heating pump may also be fitted to the side flange of the tank.
Options for connecting the water heater to various sources of heating are shown in
the drawings below.
