Boiler Servicing comprises of testing, cleaning the boiler, checking and fault-spotting, with the main focus in on testing the various functions of the appliances for safe operation. These are the basic principles that all of our highly skilled team use on every job, large or small.

Why is Boiler Servicing so Important?

Boilers may appear to be functioning correctly, but there can be hidden problems that are not obvious. These problems will be exposed by a comprehensive and professional service. One typical scenario would be the system which switches the gas off if the pilot light goes out. If this device is not performing correctly you could easily have gas leaking into your house. This device should be fully examined and tested during the service procedure carried out by Alsto Heating to prevent this from occurring.

How often should servicing be done?

At Alsto Heat we strongly recommend boiler servicing is carried out annually. This is far more important once a boiler is a few years old than when it is new.

What do our clients say about us?

On behalf of the Management Committee, Staff and Residents of Dowty House I would like to convey thanks to all your team for the impeccable service received during our recent kitchen refit project and the subsequent replacement of radiator valves.

We are absolutely thrilled with our new kitchen and look forward to reaping the benefits of the heating valves for many years to come!

We will continue to value you as a preferred supplier to Dowty House.

Carole Cook Chairman Dowty House 26th November 2015
