Boiler installation FAQs
How do I know my boiler needs replacing?
There are several signs to keep an eye on which would usually indicate your boiler is ready for a replacement.
- Your boiler is frequently breaking down
- Your heating bills are becoming too expensive
- There are strange noises coming from your boiler
- If you suspect a gas leak (if this is the case, you should call an installer urgently and do not attempt to resolve yourself)
- Boiler parts are hard to replace due to the age of your boiler and are no longer being manufactured
How do I receive my boiler installation quote?
When you have selected the Vaillant Advance installers that you would like to contact you, they will arrange for a no-obligation survey of your property. Once they have done this, the installer will suggest a Vaillant heating solution suitable for your heating and hot water needs, giving you a breakdown of product and installation costs.
How long does an installation take?
Boiler installations can take up to anywhere between a day to a few days depending on the manner of the installation. If you are getting a like-for-like swap of your current boiler, this will be less time consuming for the installer and they should be able to complete the job in around 2-4 hours. However, if you’re changing your system completely, e.g. from a system boiler to a combi boiler, this will take much longer to complete due to several external factors from the boiler, including pipework and removing your hot water cylinder.
For heat pump installations, the time it takes depends on the type of heat pump you are having installed. If you are having a ground source heat pump installed for example, this can take a considerable amount of time due to the installation of pipes in the ground, requiring the installer to dig up part of the ground on your property.
When the installer suggests a suitable boiler or heat pump for your property, they should be able to give you a more accurate installation timescale.
