A condensing boiler is a efficient forward-looking boiler that integrates an additional heat exchanger in order that the hot flue gases transfer much of their inherent heat to start to heat the cold water in the boiler. When running at peak efficiency, the water gases developed in the burning process distills back into a liquid liberating the latent heat of vaporisation.
A fallout results in this liquid, refered to as condensate, which is typically acidic, will need to be piped away to a drain or soak away. The boiler is required to be placed on a wall and the waste fumes will travel through the flue. Hot water is supplied by a modest storage tank to ensure convenient and rapid hot water availability.
Can you suggest on the right boiler size?
You should keep in mind that in the past central heating engineers oftentimes put in boilers that had a higher output than strictly necessary.. Although this ensured that there was little probability of the boiler not meeting the heat demand, even in the coldest winters, it also meant that they were only employing a part of their heat generation capabilities, and so working in an ineffective way. If you have installed additional loft or cavity wall insulation since the present boiler was installed in your house, it could well be that you will be able to fit a lower capacity boiler than the current one.
We urge looking for professional advice from a CORGI recorded fitter before choosing a suitable substitute boiler.
If I purchase a condensing boiler should I put in large radiators?
The fundamental reason for this bettered efficiency from a condensing boiler is that it has an oversize heat exchanger. More Prominent radiators would allow lower return temperatures, and so drive efficiency higher still, but the additional saving is not shown to be cost effective, as you need to remember that that the system is operating at very low capacity for the greater part of the wintertime. Whilst this assertion is correct homeowners would probably accept this in smaller properties.
The SEDBUK project looked at this, and evaluated whether there needed to be new conditions for condensing boilers. The decision was that no new recommendations were needed, and the test results forthe condensing and the existing boilers employ the same SEDBUK formula.
