Substituting your heating boiler with a combination
Substituting your heating boiler with a combination
There many types of condensing gas boiler and one main form is a combi gas boiler. One of the causes why combi boilers are very common is that they can heat water on demand.
A heating audit is advocated before you buy to ensure that it is able to be set up in your house. If you use a trained heating fitter to conduct a study they will ensure that you comply with the building rules. There are various reasons why it is more challenging to install a contemporary condensing boiler and replace a traditional gas fired boiler.
The flue output gases are cooler and less buoyant than for a orthodox gas boiler, with less warmth they can condense more quickly and result in a visible plume. Surface wetting by the exhaust gases is often seen near the flue outlet, this impact is not limited to your house and can spill over on to neighbouring houses, in the worst case scenario the output plume can impact people passing by.
The design requirements for a condensing gas boiler flue are different from old heating boilers and your existing flue may not be suitable. To complete the fitting you could find that the flue will need to be converted. Also the flue for a condensing gas fired boiler must not be shared with any non-condensing appliance.
An external drain point is needed to enable the removal of the condensate which will develop within gas fired boiler.
Experience has shown that there are many different ways to defeat any potential set up problems. A good fitter will know of these remedies and can advise you on the best approach. The installation assessment process should forecast the extra cost of the full installation and compare them with typical fuel savings over the lifespan of the new gas boiler.
Whilst you are having the new gas boiler fitted there are some choices for the set up. A change in the location of the new gas boiler frequently results from the different installation requirements. If your existing boiler was an open flue or back boiler this will unquestionably be the case. These are often mounted in an internal position away from an outside wall.
Most rooms in the household are available for the fitting with the exception of the main living room. fitting of a gas boiler in the loft is often seen in addition to the more common positioning in the kitchen or utility area.
Providing you have a sealed system you can set up a gas boiler in the loft. If you have taken this choice you must ensure that there is access to the attic through a hatch with a drop down ladder. The loft would need to have capable lighting and a boarded floor to facilitate access to the gas boiler. This will permit a plumber to get access to the heating boiler for maintenance and servicing.
