Upon completion of the installation one of our highly trained engineers will explain the operation of your new boiler. All of our boiler installations are conducted using 100% copper pipes and fittings. We do not use inferior plastic fittings on any of our installations. We have over 12 years of boiler installation experience.

Boiler Servicing

All boilers require yearly servicing in order to maintain their efficiency and extended guarantee. This will also prolong the life of your boiler and prevent the build-up of deposits that can cause damage to the rest of your system. Our servicing is the most comprehensive available and includes the addition of chemical inhibitors to your system that prevent corrosion and build-up of iron oxide, AKA sludge. Unlike competing firms, checking the boiler itself is just the beginning of our comprehensive service. Boiler servicing costs just £125 including VAT and includes:

  1. A comprehensive hot water and heating system check
  2. Bleed and check all radiator valves
  3. We use a top-of-the-range flue gas analyser to ensure your boiler is running safely and with the correct mix of gas and air. An incorrect balance can lead to carbon monoxide generation.
  4. We take a water sample to test the water quality of the system.
  5. We clean the magnetic filter and condense trap of the boiler.
  6. We fill out your logbook and log the service with the boiler manufacturer

Boiler Repair

The failure of your hot water or heating system can be incredibly stressful. This is why KT gas has invested extensively in the largest stock pile of spare boiler parts of any local heating engineering firm. This massively increases the likelihood of our being able to fix your fault on our very first visit, as soon as we have diagnosed the problem. Our highly trained technicians are accredited with all three major boiler manufacturers, and we support any brand of boiler. In the unlikely event that a part required for your repair is not available from stock, we will still arrange to have your boiler repaired within 24 hours.

Boiler Finance

KT Gas now offers finance that allows you to spread the cost of your boiler installation with an option of either monthly payments, or an interest free “buy now pay later” scheme. We also accept Visa and Mastercard credit cards with no surcharge, so you have the maximum possible flexibility when it comes to payment.
