About combination boiler
Combination boiler or

reason. Unlike the system and conventional boilers which requires a hot storage
cylinder, the combination cylinder is an all in one unit which produces hot
water for taps and central heating. Also it saves a great space in your homes
and its installation is easy and faster comparative to any other boiler.
Modern high efficiency
unit boilers are the stainless steel condensing boilers with its built-in heat
exchanger to provide hot water to a home or a building. During the cold season,
combi boiler runs when needed to heat the structure and provide hot water to
various hot appliances. Whereas in hot summer days, combi boiler works whenever
there is a need for domestic hot water. It usually takes the water from the
main supply and results in stronger water pressure. It provides you plenty of
hot water. Thus, no longer waits for the tank to refill again and again.

combi boilers – An electric combi boiler is slightly
different from all the other combi boilers as they don’t require any tank or
gas network. The water passes over an electric element in the hot cylinder

About heat exchanger
The heat exchanger is installed
inside either the heating units or its purpose is to exchange heat and either
air or water. There are different ways heat exchanger does this job. In a heat
exchanger 2 elements can run together and simultaneously. But sometime the
situation occurs that you need to replace the heat exchanger
There are several
points which should be kept in mind while replacing the heat exchanger
you are working with a boiler or a furnace, you need to undergo certain
precautions. Accidentally puncturing of a pipe can cause a ray stream bellowing
toward you. This can cause you severe damage. Therefore, prior to the heat
exchanger you should turn the electric off at the main breaker. Be sure about
wearing the work gloves as you have to work around the sharp edges and getting

the screws on the boiler or furnace, you can find several sets of screws. Once
the screws are removed, now you have to remove the metal penal. The heat exchanger resembles a metal plate
and will have the tubes coming off from it.
Replacing the heat exchanger
starting the replacement of the heat exchanger, always take an orientation of
where everything is attached. Consult the manual of the new heat exchanger and
make the adjustments with the fittings inside the boiler or the furnace.
the tools like screwdriver or wench to remove the fittings attached. Once they
are removed, now you can pull off the heat exchanger. Now start replacing the
fittings with the new heat exchanger. Once the new heat exchanger is placed you
can replace the panels and turn the power on. The system will require the time
to prime itself before operating.
