What are the different types of boilers?
As well as having an impact on price, choosing a boiler is the most important consideration you'll need to make.
Not sure where to begin? Our complete guide to new boiler installation will be able to give you more insight into what to look for, ask, and expect.
Combi boiler - these do not have a tank, and heat up water as it is required
System boiler - these require a hot water storage tank for later use
Conventional boiler - this can often be the cheapest option for most homes
LPG boiler - these boilers run on LPG rather than electric or gas
Biomass boiler (manual-fed) - these require manual supervision while warming
Biomass boiler (automatically-fed) - these feed themselves with biomass pellets
Condensing boiler - these are far more efficient at using the gas/fuel than non-condensing boilers
Why not speak to a boiler fitter near you about the different options for installation and associated costs?
Installation costs
Obviously, a new boiler won't fit itself - whether it runs on electric, gas, LPG or biomass, you'll need someone to fit it for you.
The time, skill and effort involved from central heating engineers will often vary based on the type of boiler.
For example, gas boilers will need to be installed by someone who is Gas Safe certified. If you are looking at getting a new electric boiler, then an electrician may be more useful.

What to consider with boiler installation costs
We've included a free cost calculator to help you get a rough estimate for a new (or replacement) boiler.
Factors such as location, product, size and energy source have an impact upon cost, so please bear in mind that this tool is only for information and not an accurate quote.
It is a good idea to speak directly to a tradesperson who can provide you with all of the relevant information.
Please note that the cost calculator does not include things like:
VAT
Relocation of electric or fuel pipes
Ventilation
Type of tradesperson (i.e. plumber, gas specialist, electrician)
Service charges
Delivery costs (if applicable)
The calculator is based on numbers from Checkatrade's professional estimators. They are Chartered Members (MRICS) of the Royal Institution of Chartered Surveyors and Members of the Chartered Institute of Building (MCIOB).
