@wesleyp1874 My apologies for gatecrashing your thread.

Could you let me know what your rates are on the NextPumped tariff? I have been trying, unsuccessfully, so far to get a quote for them for this tariff. I realise you are probably in a different part of the country so rates may be different but it would give an idea of how much the off-peaks and peak vary from the standard variable rate.

Admin: if my question isn't allowed in this thread, please delete my post.  Thank you.

Many thanks.

I can't add any technical advice but really hope your problems are resolved. We also had some installation issues and an installer who went out of business. We did get help from our manufacturer (Nibe) and a different installer. Reading threads on this forum helped us to understand how to run the system more efficiently and saved us around 1000 kwh per year and have a super warm house. Best wishes. Lizzie.

Take it one step at a time.  If you can get the dhw and heating to the point where they are satisfactory using the pointers I have given that's a great start, ask for help if you need it and note down what you change so you can change it back if needed.

Once the system is performing it's function we can then see how to tackle the installation issues (and which ones to ignore); the filter is the one that concerns me most.
