Buying a NEW Boiler? 6 Things You MUST Know Before You BUY!


Buying a New Boiler?

If you are building an extension or converting the basement or loft you may need to consider whether or not your current heating system will be able to cope with the increased demand. Even if you are not extending your home, an old, inefficient boiler could be increasing your fuel bills. Upgrading your boiler may be a one-off payment but you could enjoy the benefits of lower heating bills for years to come.

How much does a new boiler cost?

On average a replacement gas boiler costs about £2,500. Although the cost largely varies depending on the type of boiler you buy and the labour needed to install it. Compare quotes to make sure that you get a good deal and remember that there is a government boiler scrappage scheme which will give you cash back for installing a new, energy efficient boiler.

What types of boilers are there?

If you are buying a new boiler you can choose from a combination (or combi) boiler or an open vent boiler. Combination boilers provide hot water on demand for radiators without the need for a hot water tank, they are good because you need less space and are only heating the water that you need. System or open vent boilers on the other hand are set on a timer and use a hot water tank where water is heated and stored before being delivered to the radiators and under floor heating. The type of boiler that you choose will depend on your hot water needs and lifestyle.

How can I ensure my new boiler is energy efficient?

Since October 2010 government regulation states that all new boilers must be A-rated in their energy efficiency (88%). Most boilers installed now are condensing boilers; using a condensing boiler can increase your energy efficiency because they harness the heat from exhaust gases to heat more water, making them 12% more efficient than non-condensing boilers. You can also use the Energy saving Trust Recommended product search to help you find a high-efficiency boiler.

Who installs my new boiler?

You should compare different quotes on new boilers and installation costs. Using recommendations from friends and family is a good way of finding a trustworthy fitter but at the very least the professional should be a Gas Safe registered engineer to make sure you are complying with Gas Safety Regulations. It is also worthwhile using someone who is registered with a Competent Person Scheme, which allows installers to self-certify their work as meeting building regulations and issue a certificate of proof that it meets local authority standards.

Will my new boiler require maintenance?

To ensure the longevity of your new boiler it is important to look after your central heating system. When it is installed your installer should use a chemical inhibitor to flush the system to reduce lime scale and corrosion. Powerflushing, involving pushing hot water through at a high pressure, is a good way of cleansing an existing central heating system which may need to be done if the central heating is ‘cold spotting’ (radiators not getting uniformly hot) or if the system is heard ‘labouring’ due to a build of lime scale. You should have your new boiler serviced once a year and this should always be done a Gas safe installer.
