Thermal Earth Ltd

Great service from the engineer who helped us with our heat exchange unit which needs a new part. Our biomass boiler is regularly serviced by Thermal Earth engineers who has always been efficient and extremely capable.

Great service on site with knowledgable and friendly engineers. Always help to improve the running of our heat pump system. Missing one star as you are required to pay for engineer mileage and I live far from their base, so often adds noticeable cost to my bill, so will consider local providers too.

Most helpful and maintain the pump and cylinder.

Daniel did an excellent job of servicing our solar thermal system and left everything neat and tidy. He was very friendly and inspired confidence and took the time to answer all my very many questions etc. We would definitely recommend him. Thanks so much! V and B Hamilton

Had my air source heat pump serviced and a water leak repaired by thermal earth. I can only say the service was great and the communication also thank you

I done my Hetas refresher course there . Very good indeed

I had a ground source heat pump, underfloor heating system, solar panels and a battery storage system installed by thermal earth. Tony and his team designed the system and I can only praise his work force. From the bore hole drilling team to the electricians and the plumbers. They all know their stuff and have been professional, helpful and gone that little bit extra on site on little things such as hiding cables and pipes to make the installation as tidy as possible. The system is up and running and appears to be working well. So it’s a big thumbs up from me to Tony and his team.

Excellent renewable energy family run company. These guys are subject matter experts in this market. Have 2 separate renewable energy systems from them and can’t fault their pricing, installation and after sales service. Wouldn’t go anywhere else.

Had a system installed works brilliant we found everyone so nice to deal with, nothing was to much trouble. The aftercare has been faultless and very responsive always leaving us knowing everything they have done. I couldn’t recommend them highly enough.

STAY AWAY FROM THERMAL EARTH I very strongly suggest you look elsewhere, Thermal Earth are a disorganised and frankly rude bunch of cowboys for want of a better term. They have royally messed up our install and are unresponsive to our concerns. Their office do not communicate with each other, that is when you can get hold of someone. They sold us the dream, and delivered a nightmare. If you specifically want Mastertherm, there are much better and more reliable installers around. Walk away, it will be the best decision you've made today, trust us.

Service technician was very helpful, only slight issue is have to pay for service upfront.

Thermal Earth installed a GSHP for us a year ago. It’s been great to have spent a warm winter and to be rid of oil consumption and wood burning. With complex installations coordination and meeting timescales can be challenging but they managed pretty well. The individual installers are knowledgeable and friendly. The plumbing work was some of the best I have seen and the commissioning engineer was brilliant. Despite the pressure of work around the ending of the RHI they managed to create the installation within the time they said.

It was

Absolutely amazing course. I highly recommend all heating Engineers to attend this course.

Matt was very helpful when he got back to me. I am waiting for someone to contact me who is more local to my postcode. Thanks again for your help. Best Regards Liam

Very helpful stores person that gave me an alternative solution for a Wilo circulating pump that comes with only the pump union rubber seals and not the 1" BSP flat union nuts with connection to 22mm diameter pipe.

A ground source heat system was installed at our property over the summer by a team of highly skilled and knowledgeable workmen from Thermal Earth. Their customer service from the outset was excellent with Sam Kelly in particular providing sound advice and guidance in terms of the most suitable system for our needs and budget.

I can thoroughly recommend getting in touch with Thermal Earth for anything to do with Air Source Heat Pumps and helping with the RHI application to Ofgem. Chris Jukes in particular was excellent and helped us with this process. Jonathan and Bethan Llanwrda.

Absolute reckless driving by one of your vans. Whilst every other road user this morning on the A30 was considerate that we all needed to overtake a slow moving tractor, your van undertook and cut in leaving inches to spare and then preceded to tailgate the minibus in front. Having to suddenly brake in a line of traffic that is just speeding up in not my favorite pastime.

Don't ever install Biomass with this company, the install was shoddy and the returns promised from incentives with the Government have not materialised. Nearly every time I use the biomass system there's something new wrong with it, even after having it serviced regularly by a decent engineer (not Thermal Earth employee). Now I have a system that can barely heat the house for two hours a night, relies on vast amounts of precisely dried wood between 15 and 20% humidity, and is prone to all sorts of issues, the latest being today where I really just give up - the fan installed as part of the system started spouting water all over some expensive electrical equipment of mine(frozen water expanded and burst the internal radiator) , and it's completely knackered everything. They might be good at ground source/air pumps etc but their biomass work is absolutely rubbish.

I had a poor experience with a aparticular salesman at Thermal Earth, Matt Lee. Matt made it clear from the start that neither he nor Thermal Earth needed extra work on an AoR basis and that it would up to use to convince them our project was worth their time. This message was delivered as bluntly as I have written it. Whilst I am sure they are busy, the AoR value of our project was c. 30k, so I think the 'we don't need your work' approach was to justify a large additional initial outlay, we ended up agreeing on c. 6.5k. As the process went along over 3 months, I was repeatedly engaged by Matt Lee with one deadline or another, after Matt had what he wanted he would drop of the radar for up to 3 weeks only to return with another high pressure conversation (the investors need this today, the investors need that tomorrow). Throughout this time I repeatedly asked Matt for times scales on: outline proposals, when the deposit was required and possible construction start dates. I needed this information to plan finances and arrange other works (external insulation, roof repairs, replacement windows). Matt was evasive and never gave concrete information on: 1.)when I would receive a proposal or 2.) when the deposit was required or 3.) when they would be available to attend site. In typical Matt Lee style, he popped up in the last couple of days saying they needed the full initial payment of 6.5k in the next 2 or 3 days or the job is off (bare in mind we have already waited three months and spent c. £500 in the process). At our last discussion the deposit had been £5k with £1500 nearer the construction time. Having waited a month for an invoice to pay the deposit I had put deposits down on the other works anyway so couldn't pay immediately. I asked Matt to honour our deal but let me put the deposit down after Christmas. Matt, simply refused and suggested I should have planned my finances better! Hilarious isn't he. By all accounts the company is good but if you have to deal with Matt Lee its probably not worth the effort. The Ground Source Heat Pump is one part of a renovation project and Matt made it impossible to plan anything that interfaced with the GSHP. installation. I'd like to ring his slimey little neck. *** UPDATE*** Despite the reply to this review I have not received an email from the MD.

Hi Nicola I just wanted to say thank you to you and the service technicians who have attended our air source heat pump, particularly Daniel who went to great lengths to diagnose the problems and test the system on both visits. The fact that you were able to get someone out to us on the same day on three occasions is truly great customer service. Also I wanted to let you know how much I appreciated your response last evening – I didn’t expect one until this morning as it was well outside working hours. This was above and beyond anything I could have reasonably expected and thank you for your dedication – it certainly reflects well on Thermal Earth and MasterTherm. Best regards Jim

My ground source heat pump was installed by Thermal Earth a few weeks ago and I can’t fault a thing. Installing a heat pump can be quite a project but the team at Thermal Earth kept me updated and reassured about the process and steps involved. I opted to pay a bit more to use their in-house electrician which made everything so much easier to manage as I only had one point of contact and they coordinated everything between them.

Thermal earth were amazing from start to finish. Logistically camarthenshire to Anglesey was far, but thermal earth made it feel like a local service. Site visits initially by Tony Salini, installation by a brilliant team of lads, and awesome customer service over the phone by Chris Jukes. Nothing was too much hassle. As for the ground source heat pump, best ive seen, economical and hassle free. Top notch all round

Thermal Earth have installed an air source heat pump system in a newly built annexe. They have been totally professional from start to finish and could not have been more helpful along the way. The guys who came to install were efficient and very knowledgeable and left everything clean & tidy. Could not recommend enough.

First class service, help, advice and guidance

I got in touch with Thermal Earth to talk about renewable options for my not yet built house and I have to say they were very helpful. I spoke to Chris who talked me through the various options and it was refreshing to have an honest opinion on what would be best for me! I have not got to the stage of requiring an install but I hope to start my build next spring and I will certainly be back in touch to look into options in more detail.

The installation of a ground source heating system started in March (2020). installing a new system into our Grade II listed farmhouse, with no previous heating system was no mean feet. But thermal earth took it all in their stride. We initially had visions of surface mounted pipework snaking around the house. The boys were brilliant. They took time to work out, with us, the routes they could take trough the house. All the pipes upstairs have been put under the floor boards, and with a coupe of level changes they dismantled a set of steps to feed the pipes underneath, and feed them through another staircase and cupboards to get to where they were needed. Pipes were dropped down to the ground floor rooms as inconspicuously as possible. We have original plaster moulded coving in all the downstairs rooms and we were worried that these could be damaged-we needn't have worried. it was done so carefully that none were damaged at all. The company worked with us in the sighting of the radiators and worked around the layout of the rooms, increasing or decreasing the size of radiator as necessary in order to have the correct capacity required. There is only one radiator that I find a little unsightly, but out of 19 that's not bad and I can live with it! At the end of March the Covid -19 lockdown hit and installation stopped with us not knowing how long this would go on for. The company kept in touch and at the end of May we agreed for them to come back to completer the work with strict social distancing measures and hygiene in place. On the Monday morning the digger arrived to start the ground work outside, the boys came to finish the pipework inside and install the heat pumps (magic box!) water tanks, electrics etc. by Friday 1200 meters of piping laid in the ground and connected. The ground was put back and you can barely tell that anything has been put in the ground. Apart from a hedge bank that had to be removed to take the pipe run into the field behind the garden (Credit to the digger man - totally recommend him to be used by the company again) The system was turned-on, on the Friday afternoon and I was amazed that the pipes heated up with in 1/2 and hour! They showed us how the system works and set temperatures etc. The following week they returned to finish off, replacing the floorboards, and carpets and filling in holes in walls and generally tidying up Through out this process the staff have been amazing. Very neat and tidy workers. They cleaned up, putting floor boards and carpets/ mats back in place and hoovered every night, an absolute pleasure to have them in the house, extremely professional, polite boys a credit to the company. This system will hopefully reduce our electricity usage and reduce our carbon foot print. We are a dairy Farm and the company we supply our milk to, is keen for us to reduce our carbon foot print as a step towards a more sustainable production unit, and a sustainable product. Thank you Thermal Earth for a pain fee installation process.

I gave them 1 star because the system would not allow me to give less. 1 star is to much. We started building our dream bungalow in 2009. It had be our dream for many years and this company turn our dream into a night mare. They fitted our under ground heat source system. (I should say tried.) For the first year we only had Luke warm water. They came many time over the 1st year promising to put it right but only after us seeking legal advice did they then change the heat pump. Every year the system would break down. On top of that instead of the £400 to £600 a year to run. our electric bill was £1800 a year. I could write a book of the bad way this company has treated us. If anyone are having problem with this company at the moment please get in touch with NAPIT. This we did not know we could do at the time of having it fitted. We new all the time that there was a huge problem with the system but just didn’t no what to do. They would tell us it was wear and tear and that they system was working fine dispute us having cold rooms. We have now got another company putting the problems right Which we should have done years ago. we had years of stress and heartache because of them not playing fare and not putting right what they had done wrong.

50kw solar system installed at Industrial GRP. 1 week, start to finish. Excellent job!

Excellent service, good prices, quick install.

Great company to work with from initial consultation right through install and even after sales they have been superb Bryan Prostone

We established fairly quickly that Thermal Earth would not be able to install my new heating system, because I live too far out of the area they serve. Nevertheless, Chris went out of his way to help me - answering my questions at length and with candour even knowing Thermal Earth wouldn't stand to gain anything from my business. I'm so grateful for the invaluable help and gutted I can't use this company for installation, it's clear that they value honesty, conscientiousness and attention to detail. Thanks!

Thermal Earth came and changed my heating system to a heat pump. The installers were really polite and couldn't be more helpful. The follow up from the office has also been fantastic and the customer service is probably the best I have ever experienced since I moved in.

Fantastic service!! Polite hard working members of staff! Tidy workers that cleared up as much as they could each night! Definately recomend!

I give this company one star only because the system will not allow me to give less. I placed an order with them for some items advertised on their website. They accepted the order and took payment. Seventy minutes later I received an email from them which said they no longer sold them They said they would refund the payment but it may take "some time". A week later I had not received the refund so I emailed them to ask where it was. I did not receive a reply but, coincidentally, the refund was credited to my account on that day. They were still advertising the items for sale eleven days after they said they could not fill my order.

Fantastic service from a great company

Great place, great people. Training Academy for accredited HETAS courses. Give them a call or drop in to find out more about heat pumps, underfloor heating, wood burners and much more. They have demo units in their new building for you to go and see. Call them if you are interested in renewable energy.

I'll start with a summary, the equipment Thermal Earth supply seems to be of good quality, but the service I have received was atrocious to the point of despair. I was left feeling as though their main aim was to get the £25k out of me, with little subsequent interest in whether or not the system worked. It's taken them a year to get the system working properly and has wasted many days of my time. Initially, it kept tripping ever less sensitive and higher current RCDs, with the attitude that it was our electrical supply that was the problem. Emails and phone calls from myself and the other contractors were answered sporadically. If I managed to get a site visit, it was hit or miss as to whether their engineers would turn up at all. Twice I cancelled meetings and drove the 560 mile return trip from Hampshire to North Wales to be called at the end of the day to say they wouldn't be coming. The builder reported similar troubles. Eventally, it turned out that the brine pump was faulty, and when this was replaced at least the system didn't trip the electric. Then it went into fault mode and didn't work. In desperation after trying to get an engineer on site, I eventually went fault finding myself with a meter on the live heat pump and a Thermal Earth engineer on the phone. I managed to identify a blown low voltage supply. They subsequently replaced this, but still the system didn't work. Eventually, I had to rewire the ethernet connections, and when this was done I managed to find out the problem; an external temperature sensor was not working. When this was replaced, at last the system worked properly. However, to add insult to injury, after a year without heat in my house, two weeks later I received a call to say I was due for a £350 service! In the interests fairness and balance, I would say that they have agreed to waive this year's service costs. I guess one must expect a new system to have some teething faults, but with a complex system such as a heat pump one relies on the company installing it to respond rapidly and fix them, and we feel completely failed in this respect. I gather the installation manager has been replaced, and I should add that as other members of the company have recently become involved it has been significantly more responsive to communications. I would not, however, recommend the company which I regard as by far the worst contractor I have used recently.
