Hot Water; Valve Combination; Shunt Valve - Effecta Pellets 222 Owner's Manual

Hot water

Hot water is produced in a copper coil. There are flanges on the
outside on the coil for best heat absorption. The cold incoming
water is mixed with the heated water from the coil in the mixing
valve (1). The mixing valve includes a thermostat where you set
the temperature on the outgoing water. If you don't run the boiler
with pellets there also is a possibility to heat the hot water with the
electrical heater which should be set to 70°C for good hot water
comfort. If the operating temperature of the burner or electrical
heater is too low, the coil will not deliver the quantity of hot water
as desired for larger amounts.
When hot water is prepared in a coil, legionella bacteria cannot
occur.

Valve combination

The valve combination is there so the hot wa-
ter temperature doesn't get to scalding tem-
perature. In order to increase the temperature
turn (1) against +. You may also need to tune
the flow valve (6) to reduce the flow through
the coil. There is a safety valve (9) that releas-
es the water out of overflow tube (10) if the
pressure in the hot water circuit is too high.
Note that overflow pipe should always have
drainage to a floor drain.

Shunt valve

The shunt valve is not mounted from factory. This because you
should be able to choose side to be the flow and return to the
boiler. The supplied plastic pipe (1) is placed on the side for
the return of the radiator circuit. Then screw the pipe in the
shunt valve, do not forget the gasket. Note that you may need
to pull the two m8 bolts tightly against gasket for it to be tight.
Also note that the electrical connection (open / close) will be
different depending on which side the return pipe is placed.
