higher. This means that the quantity of water in the hot water tank and its temperature will
be lower,
- if you set the sensor lower in the channel, the operating time of the circular pump will be
longer and the difference between the temperature in the hot water tank and heating media
after the thermostat switch off will be lower. This means that the quantity of water in the hot
water tank and its temperature will be slightly higher.
CONNECTION TO THE WATER SUPPLY
Connection to water supply should be made according to the markings for the connections,
as defined in the previous chapter.
For safety reasons the supply pipe must be fitted with a return safety valve that prevents
the pressure in the tank from exceeding nominal pressure by more than 0.1 MPa (1 bar).
The outlet opening on the relief valve must be equipped with an outlet for atmospheric
pressure. In order to provide correct operation of the safety valve, periodical inspections of
the relief valve must be carried out by the user to eliminate any limescale and check if the
safety valve is blocked. To check the valve, open the outlet of the safety valve by turning
the handle or unscrewing the nut of the valve (depending on the type of the valve). The
valve is operating properly if the water comes out of the nozzle when the outlet is open.
The heating of water in the heater causes the pressure in the tank to increase to the level
set by the safety valve. As the water cannot return to the water supply system, this can
result in dripping from the outflow of the safety valve. The drip can be piped into the drain
by installing a catching unit just below the safety valve. The drainpipe fitted under the
safety valve outflow must be piped down in a straight vertical line and located in an
environment free from the onset of freezing conditions.
In case the existing plumbing does not enable you to pipe the dripping water from the
return safety valve into the drain, you can avoid the dripping by installing expansion tank
on the inlet water pipe of the boiler. Volume of expansion vessel should represent about
3% of water tank volume.
The hot water tank may be connected to the household water supply system without a
pressure-reducing valve provided the supply mains pressure is less than 0.6 MPa (6 bar).
In case of the mains pressure exceeding 0.6 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.
