JTR Heat Pumps – The South West’s Leading Heat Pump Repair Experts

Heat pump broken? Call us now on 01392 369786

JTR Heat Pumps repair and maintain heat pump systems. Heat pump systems are carbon-reducing, renewable, low-energy power solutions, which can save you money on your heating costs.

Heat pumps are a proven, cost-effective alternative to fossil fuel boilers and electricity bought from the grid. They can provide heating and hot water for as little as 30% of the running costs of a standard oil-fired boiler.

JTR Heat Pumps look after heat pump systems in homes, businesses and community buildings throughout the South West region. During a service visit we aim to maximise the efficiency of the systems installed.

What We Do

JTR Heat Pumps are an established West Country engineering business with superb knowledge of the air and ground source heat pump market.

We understand heat pump technology in detail and this gives us the opportunity not only to design systems that work, but also to service systems that are not working to their full potential, and repair systems that are not functioning as they should be. We service, maintain and carry out diagnostic works on systems that run with existing radiators, under floor heating and hot water tanks. Quite often the heat pump has been designed to work alongside existing boilers, solar heating and electrical additions which all need careful consideration when commissioning.

A good design and installation is crucial to get the most out of your heat pump. Almost without exception heat pumps have a smaller heat output than a more conventional oil or gas boiler and this should have been taken into account in the original design process. We will always be honest with you about your situation so that your expectations are met. We cannot promise that we can improve the existing system operation and performance but we have the knowledge to be able to make changes to system settings and components to run the existing system as economically as possible. It may be necessary for remedial works to be carried out. For example, in some situations it may be recommended that the insulation of the property is improved, or the system design is modified to achieve your anticipated results.

Our Services

JTR Heat Pumps are able to offer full diagnostic, service and repair works throughout Devon, Cornwall and Somerset, including:

  • Initial site survey
  • Recommendation for modification of the existing system
  • Heat pump recommendation
  • Commissioning
  • Continued after sales support
  • Maintenance
  • Diagnostic and repair works
  • Telephone support

We believe that currently there is a lack of quality after sales support in the heat pump sector, so we have made this a priority. If you have any problems or issues with an existing installation we offer friendly advice over the phone and can arrange to send an engineer to diagnose and resolve any issues you may have. We can also service your heat pump annually and carry out a system health check if required.

What our customers say

I just want to say how impressed I was with the thorough workmanship of your engineer plus his respect and explanations in my language!

Thank you again for a most excellent service from start to finish. Different engineer this time but once again a credit to your company.


Just wanted to relay to both the company and the heating engineer who came to the job how pleased I am with the service provided and his understanding of the problems with renewable energy. Nothing was too much trouble. I would definitely recommend your company. Thank you.

I would like to add a personal thank you to Matt the technician who undertook the repair of our heat pump recently.  He was courteous, efficient, highly competent and extremely knowledgeable. I am very happy that my system is now working well and delighted with the service that JTR provided.
I very much appreciated your engineer explaining to me what he was doing, enabling me to expand my (limited) knowledge on heat pumps and control. He even followed-up with additional research on a subsequent query that I had when indications on the control panel didn’t match my expectations. Thanks again and well done.
Josh and Joe did a fantastic job on our Nibe heat pump this week. They worked very hard without a break and it was a long day for them both. Very tidy as well. In all the years our Nibe has been serviced your company is the only one that seems to understand the unit. Thanks again for a great job.
Just to say thanks for your excellent service in rectifying our fault with our Daikin system. Declan was extremely helpful in dealing with the fault and giving advice on our system. Please pass on my thanks.
I want to thank you and your staff for all the help you have given me over the last two weeks when my Kingspan Air Source Pump broke down. I am especially grateful to your engineer Matthew who replaced the compressor but also explained the system and corrected bits that had not been programmed properly. He is very caring and considerate,very knowledgeable and a credit to your company. I would be grateful if you would send me a reminder in September for the pump etc to be serviced before the winter.
Can you let Matthew know that so far the boiler is running time and doing all the things it should. And thanks to Matthew for his pleasant positive and helpful attitude in a time of crisis for us.
Please also advise your boss that the contact with JTR was a real relief to us. It’s the first company we found that really understood the heat pump system, knew the Nibe product and put themselves out to offer a fast response!
From the moment we discussed our issues with Matthew, he had a good idea of what could be at fault and arrived with all the spares on board. We ended up with a few major problems with our heat pump but he worked through all of these in turn and left us with a fully functioning unit with hot water and underfloor heating – marvellous.
Up until then we had wasted a lot of money on three other “experts” who really didn’t know what they were doing – so we were without heat and hot water for nearly a week and plenty of wasted costs.
Our neighbour with a similar system was also impressed with Matthew’s knowledge and now has your business card.
I am absolutely speechless about the service you guys have given us today. Our heating only broke down during the night yet your team has replaced the Ecodan already and got the system back up running perfectly. Josh and Matt did a great job and both guys are fantastic engineers and ambassadors for your company. I have never experienced customer service like JTR has shown us today. Please can you forward this email to the big boss so he knows how good you guys are.
Once again many thanks to you and JTR for your fast turnout and quick work to get our system up and running again. I am very grateful.
