CTC UK Reviews 

Amazing products and excellent support! The team is always there whenever you need help, and Igor, in particular, is incredibly helpful.

I rang Igor after our heat pump installer couldn't help with scheduling the controller. Igor really knows his stuff and was happy to spend 10 minutes on the phone video calling with the plumber and me to get it all set up. Thank you!

Great service as always. Staff over the phone are helpful in every way from the polite call backs to the assistance from the technical engineers

We have just finished our first CTC install. The kit is fantastic! We encountered an issue with what turned out to be a faulty charge pump. We were supplied with a new pump within 24 hours and a site visit from technical support to help identify the issue. The customer is over the moon with their new heat pump.
Full 5 star experience from CTC and would highly recommend to anyone.

As usual, Igor dealt with the problem professionally and accurately. A credit to the company and the industry. Thank you

Great service and technical team. Had Igor help me with a number of faults and queries. Very quick response and always finds the solution.

Great technical support.
Found issue within first ten minutes and also made some improvements to settings.
Would highly recommend.

GoGeothermal training and centre was a great experience. The whole team are friendly and very knowledgeable. Igor explained everything in detail and delivered the course very well. Excited to get going with the installs!

Spoke to Igor who guided m through installing a new user interface on a CTC Ecozenith i550 Pro. I couldn’t get rid of a couple of alerts so he guided me through the installation from the start to the finish. What was great was that he explained everything along the way which filled in the gaps in my knowledge. Credit to the company.

Very detailed explanation on how everything works. Really impressed

I've been working with and specifying and installing heat pumps for 20 years, always found CTC's to be super reliable and since Go Geo have been offering support, I've been really impressed with their technical support. Recent problem with a 10 year old unit, fault identified and assistance to get resolved was first class.

I recieved great technical advice from Igor, which enabled me to repair a clients ground source hp,

Excellent technical support from Igor.
Took time and very knowledgeabke.
First class service.

Once again, Igor responded very quickly to my message. He talked me through some test procedures on a video call and he pinpointed the fault, which was nothing to do with the heatpump, but with a component on the hot water cylinder which had been wrongly fitted by the original installer. All running perfectly again now.
Faultless service, I would highly recommend anyone wanting a heatpump to get a CTC one installed.

We live in a remote, in Wales, off grid, and depend on PV panels/invertor-controller (Victron) generator, as an integrated system and a biomass boiler. The installation has a CTC EciZenith Pro thermal store connected to a biomass boiler (pellets) and a Rayburn lib burning range cooker with boiler. The CTC thermal store is apparently a market leader. It’s a very complex system, able to be connected to ground source or air source, heat pumps, swimming pools, etc. with a number of complicated parameters and settings, and the technical advisor, Igor, is always available very promptly and helpful in dealing with queries normally in a video call. This is rarely a quick operation, as they controls are extensive with multiple settings, but I’ve always been taken through them carefully with options carefully explored. In virtue every case over the years, we have found a solution.

The only aspect which is trying is that the manual is not in my opinion, sufficiently sit out in Laymans terms to diagnose and deal with operational problems, but with ego there we normally find a solution.

Very good call done on video so CTC could find out the problem which turned out to be not a problem with there system. Call booked for 10am answered straight away, very good service.

Great technical assistance and guidance through our first CTC install.

Igor was rapidly available and provided excellent support through the Comissioning process.

Igor was incredibly helpful with diagnosing a system fault with direct and concise information.

I had to reach out to Jake regarding an issue I had with a company we had been using which had gone bust. I couldn't have asked for a more attentive, helpful and professional experience. Amazing Thank you.

Always available, always happy to help, and extremely knowledgeable. Great team.
