ing. We therefore recommend instal-
ling an automatic air vent to allow
trapped air to escape.

A stove fitted with a water tank
may cause increased cooling of the
smoke, which can lead to problems
with chimney draught. Therefore, it
is important to use additional kind-
ling and to leave the door slightly
open for longer than normal, so the
water in the tank can be heated as
quickly as possible. A system should
also be installed to maintain the cor-
rect temperature. We recommend a
system comprised of a thermostatic
switch and a circulation thermostat,
which ensure that water starts circu-
lating only when it has reached the
required temperature.
Fig. 5 System for maintaining the
correct temperature
1: Cold water return
2: Hot water supply
3: Circulation thermostat
4: Thermostatic switch
5: Circulation pump
a: Circuit at 60°C
b: Circuit over 60°C
The circulation pump starts when
the water temperature in the tank
reaches 50ºC. At this temperature,
circulation only occurs in the tank/
Aqua kit, as the thermostat (Figs.
5,3) will not open and release water
to the rest of the system until the
tank temperature reaches 60ºC. This
process stops and starts the system
automatically. Therefore, you only
have to ensure that at least one
component that is able to dissipate
the heat is attached to the system,
such as an accumulation tank or an
open radiator.
