Seeking Help for In-Principle Quote to fix a botched heat pump installation by Heat Geek Installer

DREI · 2025-08-18T12:27:28Z

Hi all, I'm reaching out in desperation at this point, hoping there might be a qualified and willing heating engineer locally who can help me with a long-running heat pump disaster. Almost two years ago, I had an air source heat pump installed by EPC Improvements, who have since been removed from the Heat Geek network. The system was badly designed from the start, undersized radiators, inefficient component placement, poor circulation, and a buffer tank that causes around 10°C of temperature loss between the heat pump and my radiators. As a result, the system struggles to deliver even 40°C, leaving my house cold and uncomfortable. It was originally designed to run at 50°C, but even at that temp, the radiator sizing was completely inadequate. The actual shortfall across the three floors is now between 54% and 70%. I'm not guessing, I’ve had an independent assessment from a Heat Geek Elite engineer at the cost of £800, thermal imaging, flow readings, everything documented. I'm trying to get the remedial work covered via Section 75 claim, and all I need now is three “quotes in principle” (not final, just rough based on the documents provided) for the remedial work. That’s it. But despite reaching out to three companies through the Heat Geek platform, no one has bothered to send me a quote, and no one seems interested in helping. Not even Szymon from Urban Plumbers or Adam from Heat Geeks, despite their YouTube claims. So here I am, with all the documents, diagrams, reports, and data ready, yet still unable to find three professionals willing to quote for work that they agree needs doing. What I need: Two quotes in principle (even if approximate, with caveats): Minimal upgrade – reusing some radiators where possible and upgrading others to meet required output. Full replacement – all new panel radiators (Type 33/22), and optionally a new heat pump if needed Everything will be subject to confirmation at survey stage. I just need these initial quotes to complete the credit card dispute process. What I can provide: To make quoting as easy as possible, I’ve prepared full documentation: Design shortfall summary – showing that EPC undersized the radiators even for the designed 50°C flow. Real-world performance data – system only reaches ~40°C at the radiators due to buffer and pump issues. Two upgrade plans – one reusing some radiators, one with full panel replacements. Floorplan and annotated diagram – showing the system’s layout and circulation issues. Professional report – from a Heat Geek Elite engineer. After two winters of discomfort, I’m finally close to a resolution, but without these quotes I can’t move forward. I’m not looking for free work, just a professional willing to price from documents already prepared, then follow up with a full survey later. All fair caveats are welcome. It's been a real eye-opener. Everyone on YouTube talks about quality and fixing the heat pump market, but when someone actually needs help, there is no one to be seen. The system is broken, and even the people who could make a difference don’t seem willing to step up when it matters. If you’re a local heat pump installer, or know someone who is experienced and might be willing to help, please let me know. I’m based in Colchester (CO4 area). Thanks so much for reading and for any help you can offer.

@drei your proposed radiator design looks inadequate to me. The first and second floors look OK, but a shortfall of 59% on the ground floor at 45C is too much.

I could not work out what you use the ground floor for - apart from cooking - as you appear to have living space in the first floor.
