Heat Source

IPPEC's Energy Centre
Heat input = Heat lost
The heat lost part of this equation can be more easily understood and implemented. That is the more insulation used the more savings on energy is made. What about the heat input side of the equation. There are several factors envolved and they all are part of the equation.
The heat source is the first consideration. Perhaps the greatest acheivement in energy saving in recent times is the modulating gas condensing boiler.

Low consumption heat source
Cleaner and easier to maintain systems

	Gas Condensing Boilers Energy is drawn from the hot flue gases back into the heating system by the cool water returning from the heating system. The gases are cooled enough so that can be ejected in a plastic flue. This is not possible with a standard boiler since the flue temperature are up to 300 deg. C. All this heat is then lost into the atmosphere. Further savings are obtained when the boiler can modulate its flame temperature depending on the heat load required. These modulating boilers are now available in all outputs to suit commercial and domestic applications. Few oil condensing boilers are in the market. However the amount of water condensate generated is small compared to gas in the fuel burning process. The efficiency is not as high as with the gas condensing boilers. Furthermore the condensate is more acidic which can shorten the life of the heat exchanger. Not all gas condensing boilers have the same efficiency. They range between 88 to 92% SEDBUK ratings.
Fuel Savings The boiler efficiency depends on outside temperature as well as the boiler temperature. Keeping the boiler at optimum temperature through modulation and controls of the heating system improves efficiency. The term efficiency of the condensing boiler could be as high as 35 %. See controls page.
Emissions Reducing pollutants is an important consideration if we are to live an a safer world. It is said that emissions from heating buildings is the highest pollutant. Efficient boilers reduce pollution emission. Condensing boilers have lower emissions than standard boilers. Some gas condensing boilers emit almost zero CO and NOx.
Domestic Hot Water Use of hot water has been increasing steadily and the amount of energy required now exceed what is required for space heating in the domestic property. Therefore generating some of the hot water using solar power leads to savings of the extra energy used. IPPEC supplies twin coils cylinder so that the bottom coil can be heated by the solar panel. Hot water cylinders should be well insulated and kept at no more that 50 deg. C average temperature.
