Glasgow Boiler Repairs & Central Heating

Boiler Replacement Fitting – Glasgow

JSL Heating provide a quality boiler replacement and installation service for customer in and around Glasgow who are looking to replace their old, inefficient boilers with a new boiler system that can save you significantly on monthly energy bills. New boilers are so efficient that they can pay for themselves within a matter of years (dependent on house size/use/energy prices).

We offer a completely free quotation for all boiler fitting and replacements that we generate through a real conversation with you at an appointment that suits you. Our qualified Gas Safe heating engineer can assess your current boiler system set up so that our quotation is entirely bespoke to your needs.

We only use approved brand boilers which is a polite way of saying – we fit quality boilers that won’t break down in a years time. And if that is not enough, all of our work is fully guaranteed for workmanship and parts used to give you peace of mind for the winter months to come.

At JSL Heating, we understand that there is an ‘image problem’ for boiler installation companies in Glasgow. There is the general assumption that gas boiler installers don’t turn up when they say they will, take too long to do the work and leave the customers house in a mess. That is not our way. Infact, we are on a kind of crusade to prove that in Glasgow, there is at least one boiler install company that can get the job done to the standards that you would expect and deserve.

When we work on a boiler instal project, we do the following to ensure we keep your home tidy.

1 – We lay down dust sheets over carpets, cabinets, tables etc in any area that we are working on to ensure that we do not damage any of your property and we do not cover everything in any plaster or brick dust.

2 – Before we actually begin any work, we go through a step by step process of what is involved with you so that you are fully aware of what we will be doing and why.

3 – We will drain down your existing heating system.

4 – We will turn of the gas supply to the house to ensure that there are no gas leaks.

5 – We will remove and dispose of your current boiler system and any relevant pipework that is not longer required.

6 – We will fit the new boiler that you have chosen to the location that we have agreed upon and connect up the water and gas pipework.

7 – We will fit a connecting flue system to your boiler. This is the exhaust for the boiler. Your existing boiler may already have a flu so depending on its position, we may be able to replace this like for like (it depends on the existing boiler set up and the current legislations that stipulate new boiler installs flue positioning).

8 – We will add an inhibitor to your heating system and then pressurise the system with water.

9 – We will conduct a test to ensure that the new fittings are supplying gas and that there are no gas leaks.

10 – We will conduct a series of tests on your new boiler system

11 – Once we have fitted and tested the new boiler for you, we will clean up any mess, remove any dust protective sheets and dispose of any material left over from the install.

12 – Training Session. This is a fancy way of saying we will show you how to use the boiler and the thermostat. Having a new boiler installed is one thing – knowing how to work it on those cold Glasgow nights is another. We want to make sure that you know how to keep toasty warm at winter with your boiler.

13 – Once everything has been finished off, we will provide a gas safety inspection document and boiler guarantee.

While 13 may be an unlucky number, the 13 steps above show how straightforward a process a new boiler install can actually be.

Boiler Replacement Case Study

We were called by a customer in Hyndland who required a boiler replacement after their existing boiler had given up on them.  They called JSL Heating because they had been recommended to us by an existing customer who appreciated our reliable service, quality workmanship and honest pricing.


We arrived at the Hyndland address in the West End of Glasgow and conducted an inspection of the existing boiler set up and positioning.  From this, we were able to provide the customer with an accurate and bespoke quote tailored to exactly what they needed.  Our quote was approved and we scheduled in a set time to begin the work.


We made the customer aware of exactly what step by step process we were going to be carrying out so they were aware of exactly what was going on.  We removed and disposed of their current boiler system and the redundant piping before installing the new system.  We conducted a series of tests to ensure that there was no gas leaks on the newly fitted boiler before conducting a training sessions with the customer to cover how to operate the new system.


And of course we tidied up after ourselves.  Needless to say, the customer was delighted with our quality of work and was equally delighted to have a properly working boiler after having to suffer for several years with an old boiler system that was getting worse and worse until it finally gave up.
