The important information con-
tained within this guide does not
encompass every situation. Common
sense and good workmanship, to-
gether with professional installation
and correct maintenance, will ensure
the reliability of your stove.
As Heta A/S is unable to give advice
on every type of installation, we have
produced this guide to help you
choose the best method of installing
your stove.
An AQUA stove gives you even more
possibilities than with a standard
stove, allowing you to have hot wa-
ter, radiators and even floor heating
anywhere in the house.
You do, however, have to bear in
mind a few things:
The installation may only be carried
out by an authorised plumber and
must comply with all applicable le-
gislation. You must also have a basic
understanding of how the stove
works. Do not install a stopcock bet-
ween the stove and the rest of the
heating system. Incorrect operation
of the system may overheat the wa-
ter and prevent it from circulating.
Never fire the stove while the boiler
is empty, as this may cause the cop-
per cooling pipes to leak. Air trap-
ped within the boiler may also lead
to a risk of explosion. To get the
best out of your heating system and
maintain efficient burning, we re-
commend that you use Heta’s AQUA
Kit, which releases water into the
system only when the stove reaches
the right temperature.
An AQUA stove must always be
fitted with an expansion tank, of
which there are two types: open
expansion and closed expansion.
