A Boiler Safety Group
certification test is very important to identify potential problems with a
boiler. This test can be taken at the Heating Equipment for Homes and
Apartments Ltd (HET) website. There is also a list of UK based certified
testing bodies that can be contacted for advice and to give the best advice on
whether a particular boiler is suitable to be installed in your home.
The main component of
the boiler safety group test is the presence of an air vent at the inlet of the
heating system. The design is made up of the following elements: pressure
gauge, safety valve and automatic air release. Most often, the automated air
release for boiler safety systems is constructed of stainless steel.
High pressure gases
from the boiler pass through the high pressure waste valve. From here, they
pass to the inlet of the combustion chamber. If the valve washes out with high
pressure, this will cause the gas to leak into the exhaust. As mentioned above,
this is the first point at which any gas leakage problems could occur. The
boiler safety group test is conducted in order to identify the correct high
pressure and automatic air release valve and to also check the position of the
exhaust valve within the system.
Another important part
of the boiler safety group test is the equipment condition. In this section, it
has been identified where the equipment needs to be working correctly to
prevent an emergency cooling system failure. The list of equipment that need to
be included in the emergency cooling and heating system may consist of a single
point electrical ignition system, a high pressure gas fire extinguisher,
portable emergency cooling units, and non reconnectable battery backup electric
motor. The list may also contain an external fuses, trip switch, a temperature
and pressure alarm, a built-in carbon monoxide detector, and other items that
are deemed necessary for equipment functioning.
In this section, it has
been determined how much heat loss can occur when there is a complete shut down
of natural circulation within the building. In most cases, the temperature drop
will depend on the square footage of the home. For instance, if the house has
two hundred square feet of living space, it will take twenty-five degrees in
order to reduce the temperature from the inside to outside. Therefore, a
temperature gauge is required for any natural circulation testing.
Once the temperature of
the coolant in the radiators has been detected, it has been determined how many
calories should be burned for a home with the same room size. The calculations
are done using the information found in the heat recovery chart and the amount
of natural heat in the room. This is a calculation that is often times
incorrect. New heat recovery calculators are being created every day, which
will correct most if not all of these errors. The new models should become
available to the public in about two years.
