7 DHW heating

DHW can be heated up intwo ways:
– With a DHW tank
> 27
(the energy source of the DHW tank is the boiler
[1]
or a buffer tank )
– With the HYKO hygiene combination tank (DHW
is fed through the buffer tank in a stainless steel
corrugated tube heat exchanger with circulation
operation.)
– With a fresh water module
(The energy source of the fresh water module is a
[1]
buffer tank )

DHW area inBuffer tank
Warm water rises and collects in the upper-
most area of the buffer tank (= thermal strat-
ification). The DHW tank or the fresh water
module draws the required energy for DHW
heating from this uppermost area. Therefore,
this (held at an adjustable temperature level)
area in the buffer tank is also referred to as the
DHW area.

Required temperature / hystereses
A separate required temperature can be set for each
time release.
The DHW tank (or the hot water area in the buffer
tank) is charged when required until the set required
temperature is reached. A new charge starts when
the DHW tank temperature falls to the value required
temperature less hysteresis.
