Ground Source Heat Pumps

What our clients say 

When Dan did the initial survey he said that just replacing would work but that he would recommend a ‘proper job’ involving two ventilation pipes through the kitchen cupboards, along the top of the kitchen and up through the airing cupboard to the expansion tank in the loft. I agreed.

The workmen were delightful, considerate and meticulously dedicated to the intricacies of the pipe work, all in a confined space. Richard showed me a photo on his phone at the end of each day, and wheeled me over to have a look when the job was finished – wonderful – indeed a proper job.

Thank you!

...Charlie and Richard did an amazing job and very quickly . Finding that the roof mounted pressure vessel was installed without an olive was the ultimate indignity 

The change is just amazing – the heating stops and starts on request – there are no more valve induces clunks – and the boiler runs so quietly that you cant hear it most of the time .   In the past it roared when  running full blast  and I wondered that because the settings were so far out , whether it wasn’t burning excessive gas .

 Anyhow we now have a functioning system which holds its pressure and the house is dependably warm – please convey my thanks to Richard and Charlie – you have a very fine concerned and professional team.

A very efficient service thoroughly pleased with our new boiler and controllers.  Fitters were friendly, informing us at all stages of the work what was happening. Good communication beforehand and after the job was finished. Left the work areas clean and tidy.

Not the cheapest quote but Dan were very professional and informative and convinced me that Heelas would do the best job.

Richard the engineer was very punctual; he worked very hard and solved issues beyond the scope of the job.

Many Thanks for a great job

Mr Piggot, Botley


The whole operation from day one went like clockwork with no problems. The team were all very friendly and did not impact on the users in the hall.

I would have no hesitation in recommending Heelas.
