A plumbing problem that discovered a boiler problem

As you may or may not know, JSL Heating is part of JSL Glasgow and the two other division, JSL Drainage and JSL Plumbing.


We work together in perfect harmony and compliment each other in times when our customers need two services and can get them both from the same expert heating company.

So this week, our plumbing team at JSL Plumbing were on site replacing a bathroom sink and the taps that are fitted to it.

During a passing conversation with the home owner, they commented how cold they were the previous night.  While it may still be summer time, it was indeed a bit chilly the other night and across Glasgow, quite a few boilers would have sprung into action.

The fact that the customer mentioned this led the JSL team member to ask a few more enquiry questions before asking for permission to fire up the boiler to check that it was working.

It turned out that the boiler was in fact NOT working.


The cause was a faulty thermostat which didn’t prevent the boiler from producing hot water but was given it a misleading temperature so when it was supposed to be turning on at temperature X, it wasn’t.

Our plumber explained this to the customer, called the JSL Heating team to explain it and got a slot booked in for the customer to get the boiler fixed and serviced at the same time.


This issue highlights the level of service, values and friendly attitude that our team have.  They showed care and attention to the customers conversation, picked up on a potential issue before politely asking to investigate.


By finding the problem early, it has meant our customer can get the issue fixed well in advance of Winter time and know that when the cold weather truly rolls into Glasgow, that their boiler will be in tip top condition.


If you are concerned that your boiler is not working to its optimum, call on JSL Heating today to conduct a service and inspection.


We do not charge a call out fee, all of our work is guaranteed and you can book a time slot that works for you.
