Combi boiler installation
Your next gas boiler will probably be a combination gas boiler, a type of cutting-edge condensing gas fired boiler. The benefit of a combination gas fired combi boiler is that it can heat up water when called for and for this reason they are very popular.
Combi boilers cannot be fitted to all houses and you should have a heating survey completed before you buy one on this type. The gas fired boiler fitting regulations are intricate and need to be interpreted by a trained heating installer. If you are substituting your existing heating boiler with a combi boiler you will find that you cannot do a direct switch as it is now more difficult to install a modern condensing heating boiler.
With a combi boiler the exhaust gases from the flue tend to be cooler and hence less buoyant than for an older gas boiler form with less heat they can condense more rapidly and result in a visible plume. You may see surface wetting the areas which are close to the combi boiler flue exhaust outlet, or cause a nuisance to neighboring property, in the worst case scenario the combi boiler exhaust plume can impact people passing by.
Your existing flue may not be suitable for a modern-day condensing boiler requirements. To overcome this the flue might need to be modified. If you want to share the flue it can only be accomplished with another condensing gas appliance.
A liquid condensation will form inside a condensing gas boiler when it is operating and there should be a suitable outside drain point to permit this to be drained away.
Do not despair, most of these set up matters can easily be beat. This is where using an experienced combi boiler installer produces a prompt payback as they will know of the best solutions. Whilst some of these fixes will add to the fitting cost you will then need to offset these against the reduced life running costs of the condensing gas boiler.
It is not all doom and gloom however and there are choices for the set up. The new combi boiler fitting requirements will often prescribe a change in boiler location. The replacement of an open flue or back boiler are good examples of this. They are often missing an external flue.
Most rooms in the home can be used other than the primary living room. Sometimes the kitchen is used, sometimes a bedroom and on occasion the loft.
If you have selected a sealed system you can then install the gas boiler in the attic to save room. This will be an acceptable if the attic has a lower-down latch with a attic ladder. Boarded flooring will be needed to facilitate access to the heating boiler and adequate lighting is it essential. These prerequisites are so that maintenance and servicing can be performed by an engineer.
