Installing a combi gas boiler
Installing a combi gas boiler
Your next gas boiler will probably be a combination gas boiler, a type of contemporary condensing heating boiler. combination boilers are very efficient and are able to heat up water on demand making them very common.
Before you purchase a combi heating boiler you should have an set up survey to ensure it can be fitted in your home. The gas gas fired boiler fitting regulations are intricate and need to be interpreted by a trained heating installer. If you are exchanging your existing gas boiler you will find that you cannot do a straightforward swap as it is now more difficult to install a modern-day condensing gas boiler.
The exhaust gases from the flue tend to be cooler and hence less buoyant than for an elderly gas boiler type with less heat they can condense more speedily and result in an easily seen plume. The output gases can then wet areas near to the outlet, your neighbour’s home can also be impacted with this operation or worse still in the plume can cause matters for people traveling by.
As condensing boilers have diverse output requirements from conventional heating boilers your existing flue may not be acceptable. As a result you may need to change the flue. The flue cannot be shared and must be for the single use of condensing appliances.
The set up will also need to take into account the requirement for an outside drain point for the liquid condensation which develops inside the boiler.
There are many ways to beat these fitting difficulties. A good fitter will know of these cures and can advise you on the best approach. These incremental installation costs should be taken into the life-time cost assessment of the boiler.
On the plus side you do have some options for where your new heating boiler is put in. Due to the different fitting requirements a change of location is often necessary. Particular illustrations are where a condensing heating boiler is to replace an open flue or back gas boiler. They are often missing an outside flue.
Most rooms in the home are available for the installation with the exception of the main living room. fitting of a gas boiler in the loft is frequently seen in addition to the more popular positioning in the kitchen or utility room.
installing the heating boiler in the loft often saves space and it is possible providing that the boiler is a sealed system. If you have taken this alternative you must ensure that there is access to the attic through a hatch with a drop down ladder. sufficient lighting and boarded floor areas providing access to the gas boiler location in the loft are also needed. All this is so the engineer can gain access quite easily to the boiler to repair or maintain it.
