New Condensing boilers, the facts for your consideration.

A condensing boiler is a finance saving innovative boiler that contains an extra heat exchanger to enable the hot waste gases transfer much of their inherent heat to start to heat the water in the boiler system. Once running at high efficiency, the water vapour produced in the combustion action distils back into water releasing the latent heat of vaporisation.

A result will be this liquid, referred to as condensate, often acidic, required to be piped outside to a drain or water drain. The water will pass down a simple plastic pipe to the outside, there is nothing special about this although you will need to ensure that it is installed in the way that prevents the pipe freezing in winter. If the condensate cannot drain away the condensing boiler sensors will stop the boiler operating and you will think that you have a boiler breakdown. Clearing the problem is relatively simple, although this could appear very complicated if you do not know what the problem is. It is better to ensure that the installation of the condensate drain prevents this problem from ever occurring rather than ensuring that you have access to a boiler breakdown service.

The boiler is required to be mounted on a wall and the waste fumes will travel through the flue. Hot water is supplied by a small-scale receptacle tank to facilitate rapid hot water availability.

What size of boiler should I purchase?

You should bear in mind that when first fitted central heating engineers frequently installed boilers that had a higher output than strictly necessary.. Whilst this meant that there was never the chance of the boiler falling short on its requirements, irregardless of the winter weather, it also meant that they were only using a piece of their heat generation capabilities, and so functioning under their configured optimal efficiency. If you have insulated your household since the present boiler was fitted in your house, you will likely find that you will need a humbler boiler than before.

Make sure you get advice from a CORGI installer before purchasing your next boiler. The lowest price is not necessarily best in terms of boiler installation and your priority should be to achieve a safe boiler installation and one that helps to avoid future heating problems.

Do I need to fit oversize radiators with condensing boilers??

The main driver for smaller fuel consumption from a condensing boiler results from having a larger heat exchanger. Bigger radiators would allow lower return temperatures, and so enable greater energy efficiency, but the extra benefit has not been regarded as cost effective, as you need to remember that that the system is is only using a small part of its overall capacity for the bulk of the heating season. Whilst this affirmation is correct householders would plausibly accept this in smaller properties.

The process we have talked over was contained in the reference document for the SEDBUK project, and assessed whether there needed to be new conditions for condensing boilers. The decision was that no new recommendations were expected, and the test results forall the boiler types use the same SEDBUK formula.
