4. Attention!
Too low incoming and outgoing water temperature results in forming of condensation, which
additionally affects the useful life of
Etaž
. In extreme circumstances, condensate measured in
litres may form and when it starts leaking, the first thought is that
Etaž C20/C25.1
is leaking.
The condensate also contains sulphuric acid which is formed by separation of sulphur from the
products of burning. Sulphuric acid causes corrosion of sheets. The dew point depends on the
type of fuel, the atmospheric pressure and air humidity and it ranges from 45°C to 50°C. For this
reason, we have to pay special attention not to let the temperature of the return water fall below
55°C.
Etaž C20/C25.1
is not built for work at low temperatures. In particular, it should be
checked whether it is installed in a system with adequate capacity, since inadequate capacity may
lead to temperature drop and forming of condensate. If
Etaž
is lined with tar and soot, the heat
transfer is weak which also leads to temperature drop and forming of condensate.
Condensation in the boiler may be avoided by:
1. adequately selected chimney,
2. prescribed manner of stoking and prescribed type of fuel,
3. adequate maintenance of the boiler and chimney, and in particular
4. by the use of 4-way mixing valve.
Chimney is very important for the overall work of the stove. The recommended chimney has
the internal pipe diameter of 180mm and the minimal height of 8m. Provided that there are no
aggravating circumstances (narrowing at the top, high buildings nearby, too many curves in the
chimney, tar deposits, etc.) Such chimney ensures optimal performance of all three functions:
heating, cooking and baking.
