How to Choose a New Boiler

When it comes to heating and hot water, your boiler supplies warmth throughout your home. You must ensure you have an efficient device installed in your home to reduce energy costs.


If your boiler is more than 15 years old, it’s time to start thinking about replacing it. Here are some Boilerguide tips and advice on replacing your boiler.

Ask For Multiple Quotes

When you’re looking to replace your boiler, get multiple quotes from different companies and choose the one that is best for you with the lowest rates possible.

When you want to repair your boiler or change it because it looks old/obsolete/defective, remember not to go for just the first company you talk to as there are many others who can provide you with better deals.

Also, do remember that prices vary a lot, so don’t jump at the first quote offered – instead, speak to several more companies before making a final decision.

Consider Financing

If you’re looking to replace your boiler and are worried about the cost, you may consider financing the purchase.

There are several options available in the UK, so you should be able to find something that suits your needs. Consider asking a trusted lender to finance the installation so that you can pay them back over time.

You could take out a personal loan, use a credit card, or look into government schemes such as the Green Deal.

Make sure you compare different offers to get the best deal on whichever option you choose.

Choose The Right Size

When choosing a boiler for your home, size is essential. If the boiler is too small, it won’t be able to heat your home properly. If it’s too big, it will be less efficient and cost more to operate. Make sure you choose a boiler that is the right size for your home.

One way to tell what size boiler you need at home is by counting the radiators in the house. You need to ensure that you have enough power so that all of them run hot.
If you have many radiators in your home, it will be difficult for a standard-size boiler to keep up with their demand. As a rough guide:

  • <10 radiators: 24–27 kW
  • 10 – 15 radiators: 28–34 kW
  • 15 – 20 radiators: 32–40 kW

Get A Professional Installation

Modern boilers can recover heat that was previously lost via the flue, this means they can increase efficiency and reduce energy consumption compared to older-style boilers.
They run at lower temperatures but will still produce heating water temperatures of 65 degrees Centigrade when a boiler is running in what is called ‘condensing mode’.

It’s vital to hire a professional to do the job when your boiler needs to be replaced. Installing the replacement boiler yourself could lead to problems.

Hiring a professional will ensure that the job is done correctly and help you avoid potential issues.
