HOW to choose a HEAT EXCHANGER?
It is possible to heat up just a half of the house with a common fireplace. Due to the heat exchanger we can raise the extent of the heating. But there are couple of disadvantages of the exchangers such as higher noisiness or dustiness. This is no doubt the greatest risk, because the particles of dust are seated in the air duct through which the hot air is led to the other rooms.
Another disadvantage is the problem with the regulation of the temperatures in each room. Next problem is that the classical fireplace do not solve the heating of the water and do not extent effectivity of the fireplace, which means they do not extent the effectivity of the heating of the house.
While decision which type of heating to choose the most effectice solution seems to be a combination of a classical fireplace with a special heat exchanger.
A good heat exchanger has to fulfill several condicitons:
-it has to reduce the tar effectively inside the exchanger
-it cannot cold down the combustion products which would cause the tar inside the chimney
Classical heat exchnagers work on a principle of cold water on one side and the flame on the other side, which cannot not ensure the mentioned conditions for effective heating. That is why the exchangers are usually critisised both by users and by experts for their problematic function in the system of heating.
There exist a solution in the form of special heat exchanger MIJORI that counts to the top of heat exchangers ever.
The main advatages of MIJORI heat exchangers are:
-very high effectivity in getting and transfering of the heat produced by burning inside the fireplace
Their construction has been patented by Industrial Property Office of the Slovak Republic and the top parametres of the exchangers were tested and certified by Technical Exerimental Institution in Piešťany in Slovak Republic.
The effectivness of the heating
Heat losses that appear during burning are devided into three groups:
- the demand to lower the amount of hot combustion products going out to the chimney - we can achieve it to lower the amount of the air to the fireplace insert.
- although this way we can lower the chimney loss (1), the lack of air causes the growing amount of not burned gas particles (2).
- the demand to burn the wood perfectly can be achieved by enough amount of air, its perfect mixture with the gas particles from wood and very high temperature inside the cimbustion chamber. Thus the gas particles are burned perfectly, but the particles going out through the chimney are very hot, which causes the chimney loss.
