smallblueplanet That’s the quote. They do a pre-install survey - heatloss survey = to check what is needed and where it would go. I told you that no-one really knows how they work it out.
I tried octopus, jesus, it was really a 1 size fits hardly anyone. Totally inflexible and not cheap, the cosy turbo includes their DWH tank but doesn’t include rads. It also runs at an eye watering max of 65C. If the emitters are not upgraded, your COP and SCOP will be really low. e.g. every 5C temp change is 20% less efficiency, so with standard rads, your going to be running it at around 45-50C, which will be 40% less efficient than normal, so a COP of 2.4 to around 3.1 can be expected…which is very low. So £3804 isn’t a bargain price. I had 10 rads, which would ass at least 1500 to this price if not more (so it should have been £5300+ if they did the rads).
For those who want a quick, hassle-free transition to a heat pump, a Cosy Turbo installation is the way to go. We run our Octopus Cosy heat pump at a slightly higher temperature than standard (up to 65℃) and it works efficiently with your existing radiators and plumbing, meaning fewer changes to your home’s existing heating system.
While a Cosy Turbo heat pump will cost more to run than a lower-temperature heat pump, it remains highly efficient throughout the year. Pairing it with our Cosy Octopus tariff helps keep running costs as low as possible.
Next the Cozy Eco: £4666, which on the face of it seems good, but when I mentioned my pumped showers…not working on a pressurised system (my problem, they would deal with it at installation) which meant getting plumbers in at a later date to tie into the system Octopus put in, with possible warranty issues.
