1. How long does it take to fit a new boiler?

6 common myths about boiler replacing busted

Many people are put off by replacing their boiler because of the misconception that it will take too long. The reality, however, is that you can replace your boiler in as little as 4-6 hours. That’s right, if you’re swapping out your previous boiler for one of the same type and specification, and providing all the gas, central heating and water pipes are already in place, it should take an engineer less than a day to do.

However, a straight swap is not always possible, and boiler replacement will take longer in other scenarios:

However, a straight swap is not always possible, and boiler replacement will take longer in other scenarios:

  • Changing the location of your boiler (1-2 days)
  • Fitting a completely new combi boiler (1-2 days)
  • Changing the type of boiler in your home (2-3 days)
  • Changing the type of boiler and moving its location (3-4 days)
  • Changing your boiler’s fuel type (2-3 days)

2. Combi boilers are unsuitable for larger homes

Although it is true that standard combi boilers are better suited to smaller properties, there are options that are perfectly capable of providing heating and hot water to larger homes. For example, if you live in a very large home, we recommend a combi boiler that generates at least 35kW of power.

However, storage combis, which have a built-in tank containing pre-heated hot water, are also available. So, homes with multiple bathrooms can have an adequate supply of hot water throughout the day.

3. I need planning permission to replace my boiler

This is very rarely the case; provided all the work to replace your boiler is done internally, planning permission is rarely required. If you live in a listed building, however, you can check if you will need it for internal alterations by contacting your local planning authority.

Planning permission works slightly differently for boilers that have a flue outside. However, you can usually get around planning permission by meeting certain conditions:

  • If the flue is on the rear or side elevation of the building, it should be no more than 1m above the highest part of the roof
  • However, if you live in a listed building or a designated area, it is advisable to check with your local planning authority before a flue is fitted.
  • For properties in conservation areas, National Parks, World Heritage Sites, Areas of Outstanding Natural Beauty (AONBs), and the Broads, flues should not be fitted on the principal or side elevation if fronting a highway

4. The best boiler is the most expensive one

This is simply untrue. The reality is the best boiler will depend on a variety of factors, such as the size of your home, your existing boiler, and the amount of fuel you consume. We’ve created an informative guide where you can compare the prices of different boiler types to help you find the best option for your home.

5. A bigger boiler means more heat

This is another myth replacing your boiler that is simply not true. This is because the amount of output from your boiler is determined by the size of your radiators. Therefore, using a high output boiler to power small radiators will not lead to more heat.6 common myths about boiler replacing busted

When looking for a new boiler, it should be sized in accordance with your radiators and the size of your home. This will ensure the optimum amount of energy use, helping to keep your heating bills down.

6. Condensing boilers are inefficient unless fully condensing

Almost all of the boilers fitted today, no matter what type, are condensing boilers. However, they do not need to be fully condensing in order to be efficient. Today’s condensing gas boilers, for example, are around 84-92% efficient. Modern non-condensing boilers, however, are about 78% efficient, whilst older ones tend to only be around 55-65% efficient.

If replacing an old non-condensing boiler that is G-rated with a high-efficiency condensing boiler, it is also possible to save as much as £310 a year on energy!
