Hello all, I hope someone can help me. We've recently had a Worcester Bosch 7001i ASHP installed, with an HPC 410 user interface. I'd like to access the service Menu to check the settings for the heating curve and DHW. However, I don't seem to be able to bring up the service menu by following the instructions in the installation manual (press and hold both the selector knob and menu button for about 3 seconds). Has anyone any ideas? Do I have to hold my face a certain way for it to work 😄? Thanks in advance.

House is fully double glazed and is 201 square meters from the EPC. Average oil consumption over the last 10 years is 1889 litres, hence rounding to 2000. But really, my main query was about the possibility of using existing rads and piping if we did look at ASHP. Thanks again for all the views. By the way, I don't think A2A is likely to be the way we go. The house is long and any A2A system would only be able to heat one room.

Thanks for the comments everyone. EPC reckons heating at 23000kWh per year!!! I suspect based on the oil consumption it is nearer 15500, especially as the 2000l is rounded up. I think I'll get some quotes and see what they say. I know cost wise it's likely we'll not do anything!!

Current electric is 30.42p per kWh, fixed until next May. It's an EV tariff but we can't get a smart meter as no signal! We have a 7 kW PV system with 2 x 8.2 kW batteries. The oil boiler is just a standard condensing boiler. Hot water cylinder is standard unvented, mainly heated by solar diversion, sorry, no idea of size but not huge.

Many thanks for the replies. Plenty of food for thought. The motivation for considering ASHP is that our current oil boiler is 15 years old and will need replacing sooner or later but government plans are looking at banning the sale of oil boilers from 2026. So it's either replace in the next 18 months, go ASHP while there is a grant available or wait and see but probably have to go ASHP in the future anyway.

Thanks for the reply. We are off grid for gas, heating is by an oil boiler, we use 2000 litres a year, averaged and rounded up. Output temperature from the boiler is 60 degrees C, return temperature is 45 degrees. The house is 201 square meters, according to the EPC. Hope this helps.

Hello, I've just joined as I've been reading the forum for a while and found it very useful. My next project could be an air source heat pump but I'm not sure yet as we have 12mm piping buried in the walls and I don't want to have to redo all the piping. House was built in 1992, with cavity wall insulation and the loft insulation has been topped up. Any comments and suggestions gratefully received.
