New Boiler Replacement and Installation Guide

A boiler is the heart of your home’s central heating system. Getting a new gas boiler replacement installation can therefore be a complex and admittedly expensive process. Here at HomeServe, we understand how difficult this process can be and we’re here to help you make the best decision to suit your home and needs. Here’s a few factors that we believe you should prioritise when choosing your new boiler:

 

 

How much does a new boiler cost?

“How much is a new boiler to install?” This is likely to be one of the first questions on your mind if you’re considering getting a boiler installed into your home. New boiler prices can indeed be pretty costly, but the right boiler could deliver effective and efficient heating and hot water to your home and ultimately make your household a more comfortable place to live – an investment we believe to be well worth making.

New boiler prices can vary greatly, the expense for one household may be cheaper than that of another. For example, the boiler replacement cost for their current combi with another of the same type could be less than an individual looking to switch from a regular boiler to a new combi boiler. Costs could also be dependent on factors such as the type of boiler chosen, its size and the complexity of the installation process. For instance, if additional parts or labour (such as scaffolding or pipe-rewiring) is required, additional fees may be incurred. Here at HomeServe, we aim to offer first-class installations of top boiler brands, such as Worcester Bosch and Baxi, at competitive prices. We aim to ensure that you get the best value for your money in relation to your boiler, the installation and the service you receive.

Things to consider before buying a boiler

As a boiler installation is generally an important and expensive affair, there are a number of factors that you should take into consideration before taking the plunge. These include:

 

1. kW output/The size of the boiler – This is one of the main factors to take into consideration when purchasing a new boiler system. A kW output dictates a boiler’s ability to cope with your household’s heating and hot-water needs. The required output tends to be reliant on the number of bathrooms and radiators that are present within your home, so if your household tends to have high central heating demands, you may need a boiler with a higher kW output. It would also be beneficial for you to think about the physical size of the boiler and establish the types of dimensions that would be able to fit comfortably in your home.

Here’s an estimated guide of kW outputs to help you determine the type of boiler that could be suitable for your home:

24-27kW 1-2 bedroom, 10 radiators, 1 bathroom
28-34kW 3-4 bedroom, 15 radiators, 1-2 bathroom
35-42kW 4+ bedroom, 20 radiators, 2+ bathroom

2. Reliability –A reliable boiler could save you both stress and money in the long run as boiler breakdowns can be both highly inconvenient and expensive to fix. Investing in a reliable boiler could prevent you from being left in the cold and could also save you money in repair costs, so bear that in mind during your decision-making process. Here at HomeServe, we always aim to supply the most reliable boilers, so contact us if you’d like our help deciding which option could be the best choice for your home.

3. The location of your new boiler – The location of your boiler could impact the spacing and appearance of your household, you should therefore think about a suitable place for it to be fitted. It often saves homeowners time and money to place their new boiler in the same location as their old one, as this typically enables a quick and easy installation. However, if you believe that your boiler could be better suited elsewhere, there are a number of locations that you could choose from.

4. Energy-Efficiency – An energy-efficient boiler could allow you to make savings on your energy bills by reducing your energy wastage**! All of the boilers that we stock at HomeServe are A-rated for efficiency and could be coupled with a state of the art thermostat (such as Nest or Netatmo) to potentially provide you with the ultimate energy-efficient, central heating system. Boilers such as our Worcester Bosch Greenstar 30i are built with key feature such as user-friendly controls to enhance efficiency by allowing you to set your heating to your preference and avoid energy wastage. According to the Energy savings Trust, replacing a G-rated boiler in a semi-detached property with an A-rated boiler could save you up to £210 on your annual energy bill!**

5. Installation Time – Another key factor to consider is the length of time your boiler installation could take. A boiler installation could take between 1 to 5 days depending on the work required. System changes often take longer than like for like swaps, for instance, a change from a regular boiler to a new combi boiler is likely to take longer than a straight combi to combi swap. It is in your best interest to consider the time it could take for your new boiler to be installed, as this could give you an idea of how long you could be without your central heating, as well as providing you with a timeframe should you have to take time off work. Our friendly and reliable Gas Safe engineers aim to complete all installations quickly and thoroughly and are committed to getting your heating and hot-water up and running as soon as possible.

 

6. Get an engineer’s opinion – Last but not least, it is often beneficial to get an informed opinion from a qualified engineer to ensure that you’re making the best decision about your home heating. One of our expert surveyors would be more than happy to conduct a survey at your home and will aim to provide you with the best advice. We can recommend a boiler type, brand and model for your home, so don’t hesitate to contact us if you’re in need of help.

When's the right time to get a new boiler?

On average, boilers last between 10 and 15 years. So, if your boiler is coming up to this age, it may be time for you to consider getting a new one installed. Besides their age, there are a number of other reasons for replacing your old boiler system. This could include:

 

  • Beyond economical repair (BER) – Last but not least, it is often beneficial to get an informed opinion from a qualified engineer to ensure that you’re making the best decision about your home heating. One of our expert surveyors would be more than happy to conduct a survey at your home and will aim to provide you with the best advice. We can recommend a boiler type, brand and model for your home, so don’t hesitate to contact us if you’re in need of help.
  • Moving the system – If you’re unhappy with the location that your boiler is in, installing a brand-new boiler could be more worthwhile. It could also potentially be less-hassle as you’ll have the option to upgrade your system and get a more energy-efficient source of central heating.
  • Current system fails to meet your needs – Many homeowners opt for a boiler replacement if they find that their current system struggles to meet their heating and hot-water needs. For example, a homeowner whose property has high hot-water and heating demands may choose to install a boiler with a higher kW output.
  • Low energy-efficiency rating – Boilers with low energy-efficiency ratings could cause higher energy bills. It could therefore be beneficial for homeowners with low-efficiency boiler systems to invest in a system that has higher levels of energy-efficiency, as this could enable more savings!** The UK government is keen to promote the installation of A-rated energy-efficient boilers, in order to increase savings as well as protect the environment. Read more about some of the government’s schemes for energy-efficiency here.
  • Selling/renting your property – A house with a new boiler fitted could be more appealing to buyers and tenants than a home with an older and potentially less energy-efficient system. It could therefore be beneficial for you to invest in a boiler if you plan on selling your home, as this could enhance buyer/tenant interest.
