CTC UK Reviews 41

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.

Very helpful and knowledgeable when it came to set up of this heat pump equipment!
As an installer it made commissioning of the system straightforward

Had a problem with my heat pump, sent a video & info on the fault to Igor in technical. He responded immediately with advice & photos to help identify the fault. Sent out the required part next day, which my electrician fitted.
Then Igor helped via video call with the settings (at the weekend!). All good now.
Excellent service - Igor couldn’t have been more helpful.
Thank you so much 😊

Great technical support. I have been installing heat pumps for 10 years. Installed correctly CTC heat pumps give you great control and reliability over your heating system. Quality products.

New install today, called technical support for assistance with the wiring. Jake was brilliant and gave all the information I needed. Always available, very easy to deal with. Thank you for the help Jake, pleasure dealing with you. Highly recommend the system and your support.
Many Thanks

Complaint Regarding Persistent Product Failures and Inadequate Support

In late 2018, two systems were installed in near-identical properties. These systems failed to function properly for the initial few months, requiring numerous visits from a CTC Technical Manager. Despite repeated attempts to resolve the issues, including one incident where the manager fell from a ladder and caused further damage by pulling pipes down, the problems persisted.

Approximately six months after installation, the cooling module in House A failed and was replaced under the supervision of the CTC Technical Manager. Over the next four years, both systems consistently underperformed, resulting in cold homes during winters, an inability to fill a bath more than halfway, and repeated failures of sensors and heat plates.

In 2024, the cooling module in House B failed and required a two-month wait for replacement. A second cooling module was installed in September. Shortly thereafter, the cooling module in House A failed again and was replaced with a third module in November.

On Christmas Eve, the second cooling module in House B also failed. As of now, we are awaiting a response from CTC Sweden, as no replacements are reportedly available in the UK.

The repeated failures, prolonged delays in obtaining replacements, and inadequate performance of these systems are unacceptable and warrant immediate resolution.

UPDATE PENDING

Recently had a CTC Ground Source Heat Pump installed. Needed help with some settings on the control system. A quick video call with one of the tech guys and it was all sorted. Very helpful and friendly to speak to.
