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 pellet 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 water tem-
perature doesn't get to scalding temperature. 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 releases 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.
