3.2 Basic rules and prescriptions.
The stove with water jacket operates on water heating boiler principle.
The advantage of this type of heating system is the maximum utilization of the heat that is pro-
duced during the combustion process. With this method the heat from the combustion chamber
is taken to remote and hard to reach for a normal heat exchange premises in order to maintain an
even temperature and warmth comfort.
• Ensure that every branch and element of the installation is airtight at every single moment of its
exploitation.
• All elements of the installation must be protected from freezing, especially if the enlarging pot or
other parts are situated in non-heated premises.
• The circulation pump can be chosen by the capacity required by using the following formula:
G=0,043. P , (m³/h), in which:
P, kW is the heat output of the water jacket. The circulation pump can be turned on and off
by the means of a thermostat in combination with an electric switch
• The first service cleaning of the pump’s filter must be done immediately after testing the installation.
• If an old installation is going to be used it must be washed several times to ensure the removal of any
accumulated dirt on the surfaces of the water jacket.
• Do not drain the circulating water of the installation during the non-heated season.
• Chemical treatment of the circulating water is not recommended.
Chart 1 is a basic combined chart for heating with solid fuel stove, electrical boiler equipped with
water serpentine and a solar panel. For economy and efficiency of the system and a constant avail-
ability of cheap hot water a qualified assembly of the automatic shifter controlling the thermal
flows to and out of the solar panel and the boiler is required.
Chart 2 shows a one storey heating with a compulsory circulation. The advantage of this chart is
that the water-conducting elements can be hidden.
The enlarging pot must have a direct atmosphere connection which means that it must be placed
on the highest spot in the system. Its capacity can be determined as 0,1 part of the total capacity
of the system.
The filling or unloading of the system is done via a hose through a facet mounted in the lowest
area. Mounting a membrane enlarging pot is permitted when constructing a closed type system.
During the initial 3-4 start-ups a condensation on the surfaces of the water jacket may occur
which depending on the fuel’s humidity and the temperature of the incoming water may reach
0,3 litr on a single start-up. The accumulating char reduces the temperature difference and the
condensation.
•
“Mareli Systems” provides a warranty and out of warranty service and replacement of the
water jackets.
• The warranty is not valid in case of a stove with a swollen water jacket which is a result of
pressure increase in the system and improper connecting.
• The water jackets are tested under pressure of 400 kPa (4 bar).
It is recommended that the assembly is performed by an authorized specialist.
