Boiler services offering modern technology with traditional service.
Johnstone's are a specialist central heating installation and service company, offering expertise and the high level of customer service that you would expect from a leader in the field.
Modern Central Heating Systems have improved remarkably over the last few decades, including the introduction of combination boilers in the late 1970s and the introduction of high efficiency boilers more recently offering efficiency ratings of over 90%.
We are experts in central heating system design, repair, installation and servicing. We offer a wide range of services through our team of fully trained and qualified Gas Safe Registered engineers.
Our Gas Safe plumbers have many years of experience and good track record of happy customers. Within our wide team we have the expertise to deal with simple and complex heating problems. Whether it is a simple boiler breakdown, an installation of an unvented hot water tank or a full underfloor heating system design and installation, we can carry out the work efficiently and cost-effectively.
Our Gas Safe registered plumbers (previously Corgi) and heating engineers are experienced in boiler repair and central heating repair on all types of gas boilers and central heating systems.
Although central heating systems are taken for granted these days, they actually only started to take off in the 1970s in the UK. Currently it is hard to imagine our life without a modern central heating system.
Boiler Breakdowns - Fault Finding Process
Our Gas Safe (formerly Corgi) registered plumbers will go through a rigorous testing cycle to analyse your central heating and boiler to find the root of the fault.
As part of examining the boiler and the central heating Edinburgh system together with the connections, the plumber will check:
- Flow and return pipes (to/from the boiler)
- Boiler flame firing
- Flue positioning and heat
- Lockout on the boiler
- FCU fuse (power to system)
- Boiler and heating controls (programmers, thermostats)
- System pressure
- Condition of radiators
- Condition of pipe work
- Condition of valves and other fittings
Once the engineer has clearly diagnosed the problem they will be able to advise on the best solution to resolve it as soon as possible. Inmany cases it is more cost effective to replace your boiler rather than repair it, as the energy savings from the new boilers outweigh the cost of repairing an old boiler.
