Gas Boiler Installation

When it comes to the installation of a new gas boiler, there are a number of important things to consider, first here to install it, if you are simply replacing the existing boiler then it would seem the most economic and logical to install it in the same place if it is about the same size as the old one, but this may not always be the case.

If you are changing boiler design from an old style to a combi then you will be having it installed on a wall surface near an outside wall for ventilation and drainage, there should be no problem with installing gas and hot and cold water pipes to a boiler this way. The boiler should also always be installed in a place where it is able to drain, as modern condenser boilers are required by law to have a drainage outlet for waste water to run off.

You also have the size of boiler to consider, they range between 40Kw and 25Kw, 40kw would be for a large house, whereas 25kw would be typical for a flat, most installations for the average house will be around 30kw, depending on the number of radiators needed and the hot water demand of the house’s occupants. If you are installing a new boiler and keeping the original radiators then you must get them flushed before connecting the pipes to it. Sludge may be present in the radiators and it will flow into the new boiler and do damage to it or at the very least be an inefficient system as a result.

When it comes to choosing the make and model of boiler it’s best to go with the recommendations of the installer, as they will be the most familiar with the installation and running of that model. You should spend some time doing research about the pros and cons of different boilers before making a decision, you can ask for brochures and maybe see some demonstration models to see if you like the way they look and are controlled. Check how long the guarantee is for, the longer the guarantee is, the better, although some of the more expensive models only come with a two year guarantee, others with up to five years.

You need to allow for at least one full day without hot water or radiators for the duration of the installation. As for cost expect to be paying between £1500 and £1900 for a combi boiler plus installation costs.

One option that is popular and quite cheap for controlling the thermostat is a wireless remote control, which can be particularly useful for bedrooms and living rooms for ease of control.
