What type of boiler service do I need?

At Expert Heat we offer two different types of boiler service, a standard service and a full strip down service.
a standard service checks the boiler is running correctly, cleans out magnetic filters and condensate traps, adjustments of the gas valve if necessary and a combustion analysis check. This type of service is usually sufficient for most boilers however we do recommend that at least once every 5 years your boiler has a full strip down boiler service, which is a more in-depth service which will sometimes require worn parts to be changed.

short answer YES. So all boiler manufacturers will require that the boiler is well maintained to keep the warranty, this means an annual gas boiler service will be required.

Who do I call if my new boiler breaks and needs a warranty call?

If your new boiler has a fault and we installed your new boiler then generally we say to call us first as we can go through some basic steps with you in order to work out if a warranty call is needed. If a warranty call is needed then we will call your boiler manufacturer and arrange this for you.

The time it takes to install a new boiler depends on what you currently have in your home. A straight swap boiler can be done in 1 day, however if your system is in need of a Powerflush then a 2nd day would be required.

if you have an older system with a hot water tank and wish to change this for a new combination boiler then this should take around 2 days, again if a Powerflush is required then this would need a day so would take the job to 3 days.
