ASHP Short Cycling
This is my first season with a ASHP and wet underfloor heating system. In the last months I have struggled to solve the short cycling of the heat pump (HP). Initially it was thought that because the bungalow was well insulated (modern new build) and it was mild, and it was just the mild weather conditions causing the…

Daikin Altherma Heat Pump - can you determine whether/how much it is heating radiators or tank?
Hi, We had a Daikin Altherma 3 M (EDLA06E2V3) Air Source heat pump system installed by Octopus in Spetember. (In case it's interesting, we're in Leeds, and we paid £1500 after the grant, which included removing the gas boiler and replacing 3 radiators). In general, we are extremely pleased with it. Our house is now warm…

We have a Danfoss DHP-AQ Maxi air source heat pump that has stopped working nearly 3 weeks ago. It doesn't provide heat for the house or hot water but there are no error messages. The symbol for the water tank just shows as permanently filling but doesn't heat. The outside unit isn't running either. Inside the unit on a…

Heat Pump v Electric Radiators
Hello Has anyone seen an independent comparison of the cost of 1) Installing a heat pump, typical pipework amendments, extra loft insulation, running costs versus 2) Purchasing portable electric heaters ( say https://www.toolstation.com/2kw-convector-heater/p77317?) and suffering higher electricity bills over say a 20 year…

Anti freeze system
Now that we've had our first cold night of winter (I live on Anglesey, north Wales) the anti freeze system of my air source heat pump and heating system has kicked in. When the outside temperature falls to 5 degrees and below, the water pump switches on and ensures the water in the system is flowing, thus ensuring it…

Heat Pump Question
Quick question about heat pumps. We currenty have a gas boiler. Whenever we want heat, we "boost" the heating (to a temperature the house will never get to) for an hour or so. It's on a timer to come on and off in the mornings and evenings. After the boiler turns on, we feel a difference within 15-20 mins. Our flow…

Pipe sizing to supply rads for 30 degree flow temp ASHP?
We're mid-ASHP install. Initially the installers told me that the SCOP improves with higher flow temps and that they'd spec'd rads for 55 degrees. I knew this was not right so it prompted me to do a bunch of research. I've now reached a bit of a dead end with my self-directed learning on this stuff and could do with a…
