Combi boiler set up overview
Combi boiler set up overview
Most modern-day boilers are condensing gas boiler and a combi boiler is of this type. It delivers water as needed and is the most popular form of heating boiler in the UK.
A heating audit is advocated before you buy to ensure that it is able to be set up in your house. The gas gas fired boiler installation regulations are complex and need to be considered by a trained heating installer. It is sometimes more difficult to set up a condensing rather than a non-condensing heating boiler for many reasons.
The flue exhaust gases are cooler and less buoyant than for a traditional gas boiler, with less warmth they can condense more speedily and result in an easily seen plume. Surface wetting by the output gases is often seen near the flue outlet, neighboring homes can be impacted by this effect, on occasion people going past your house can be impacted by this exhaust plume.
The design essentials for a condensing boiler flue are different from old gas boilers and your existing flue may not be acceptable. To complete the installation you could find that the flue will need to be modified. You cannot share a condensing boiler flue with any other non-condensing appliance.
A liquid condensate develops within the heating boiler, and must be able to be released to a suitable drain or soakaway.
Do not despair, most of these installation issues can easily be beat. A good installer will know of these remedies and can advise you on the best approach. These additional installation costs should be taken into the lifetime cost assessment of the gas boiler.
On the plus side you do have some options for where your new gas fired boiler is set up. A change in the location of the new gas fired boiler frequently results from the different installation requirements. Particular examples are where a condensing gas boiler is to replace an open flue or back gas fired boiler. An external flue is often missing from the fitting of these older heating boiler types.
Providing you do not instal the boiler in the main living room most other rooms are acceptable. In addition to the kitchen or utility room often the loft or bedrooms are used for gas fired boiler set up.
fitting the boiler in the attic often saves space and it is possible providing that the boiler is a sealed system. This will be an acceptable if the attic has a lower-down latch with a attic ladder. Access to the gas fired boiler should be provided over a boarded floor and you need to ensure that there is sufficient lighting in the loft. All this is so the engineer can gain access quite easily to the boiler to repair or maintain it.
