Heating furnaces with a water circuit: varieties
A host planning to install a furnace with a water circuit must remember that it is necessary to heat it constantly when frost occurs. If you miss a few frosty days, the coolant will freeze. Homemade furnace devices are brick, cast iron or wood.
Brick furnaces with a water circuit
If the furnace is already available, then such a construction does not require a special bookmark. It will be enough to install only a special hot water tank. It is he who will provide the entire system with a coolant. This pretty simple design can be mastered by anyone who wants to make their home more comfortable.
A tank for water heating from sheet steel is produced, which must withstand aggressive internal environment and high temperature. The thickness of the walls of such a tank should not exceed three to four millimeters to ensure proper thermal conductivity. Thicker walls are heated longer, which means that the efficiency is lowered.
For brick kilns, there are no standard size tanks. Each container is manufactured for a specific furnace and is calculated to its dimensions. In this case, the height distance should be at least 400 mm: this will ensure free access. When calculating the length of the tank, the required amount of coolant is taken into account.
Cast iron furnaces with a water circuit
Cast iron structures have their advantages. First, the thicker walls of such a furnace burn out much more slowly( if compared with steel).Secondly, the heat transfer of the metal is lower, so the heat persists longer.
Heat accumulation of cast iron kilns is eight percent higher than that of steel furnaces( at the same weight).This is because the specific heat of cast iron is higher. The heat transfer coefficient of the alloy is 1.5 times higher, which means that the heat from this device is transmitted faster. It is important to heat water in a heating system.
Modern cast iron furnaces often have water jackets made of stainless steel. Interestingly, such structures are not built into the base of the floor or walls: they are portable and have adjustable legs.
Professionals recommend to check that the expansion tank is full before starting the unit. It is strictly forbidden to operate cast iron ovens with a water circuit in the absence of water in the system.
Woodburning stoves or furnaces Bugleran with a water circuit
Furnaces of Boulergian are heated exclusively by wood: they refuse to work on other energy carriers.
This construction is a horizontal cylinder, separated by a partition. The lower part is intended for firewood and for creating the necessary temperature. And the upper part - to burn out the remaining products or pyrolysis gas.
Firewood in such a furnace does not burn, but smolder. Thanks to this, one boot is usually enough for 10-12 hours. The pyrolysis gas, produced during combustion, carries more energy than the wood itself: the air in the piping pipes reaches a temperature of 120 °.
Bulerjan with a water circuit should have a chimney or a good ventilation system. Otherwise, they become life-threatening.
It is recommended to clean the ventilation ducts from soot and condensate at least twice a year for safe operation.
Furnace fireplace with water circuit
Furnace fireplace with water circuit is easily installed in any central heating system. In working condition, the fireplace through the water circuit transfers heat to the central heating system. This can significantly reduce gas consumption: energy consumption can be reduced to a minimum.
Furnaces with a water circuit usually have good reviews. However, having decided to install such an oven at home, consider the peculiarities of your home and the climate of the region in which you live.
