The settings on my heat pump are all correct and the water heating is not happening at the same time. After reading all your responses, I am confident that I have been misled. I am more frustrated that they are trying to convince me to run the heat pump at 55 degrees or more just to make up for their failure. I have contacted them to complain about the issue and will update when I receive a response. In case you are all interested, the company I used is called Rural and Country Energy.

I've been through the build and insulation of the house and there are zero issues with that thankfully. I believe this issue is just getting the heat into the rooms via the radiators.

I feel for you not having good insulation, I'm losing my mind over a couple of degrees 🤣 I will keep you updated, can't imagine it's going to be an easy process. I do believe the heating system would work great if the radiators were correct. Hindsight is a wonderful thing.

Yes it was 50% funded by a government grant. I'll take it up with them, otherwise if no resolution can be found I'll have to take it further like you said. Gutted we found out the hard way unfortunately.... it's going to be a cold and expensive winter.

The aim was to make the house as green as possible and stop relying on things like oil especially as we were expecting the oil cost to rise. We weren't expecting a magic cheap source, just one that cost around the same but worked and it doesn't even provide anywhere near the warmth we need in the house. The company that installed our ASHP provided advice on what we'd need and recommended the radiators weren't changed. Now we're left with a heating system that doesn't heat the house and we've got no choice but to upgrade the radiators.

It seems when I asked them if the radiators will need upgrading, they have lied to me completely. I'll have to take this up with them as it's immensely expensive running at 50+ and not getting the rooms to a comfortable temperature in the process. Thank you for your advice!

It's a detached 4 bedroom house, new build (Feb 2022) and insulted very well above building regs. The original heating was an oil boiler. The company that designed the original heating system with the oil boiler are telling me the radiator output isn't good enough for the house where as the ASHP installer are telling me it's fine as long as your flow temps are 50+ degrees.

Hi, I've recently had an ASHP installed (Mitsubishi Ecodan Monobloc 8.5kw) and have found since it's install in July there have been no issues with it. However, since November where temperatures outside have dropped below double digits, I am unable to get a single part of the house up to 21 degrees even when the flow temperature is set to 55 degrees for 24 hours. I have contacted the installer and explained this but they are advising me that I need to run the heat pump at max during the colder months. I don't feel this is correct and that the issue may be that the radiators in my house aren't correct sizing, even though they inform me they "should be okay if the flow temperature is at least 55 degrees. This is costing me lots of money in energy bills when we were sold this as a cheaper alternative to heating our home. Any advice would be great!
