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…

Advice on a Daikin Altherma 3 by Octopus
Hi! I've been given a quote for a Daikin Altherma 3 (EDLA08E2V3), and am seriously considering it. The quote is just shy of £4000, which I don't think is too bad. I haven't had any other quotes, but Heat Geek estimated over £6000 on their website. Octopus would replace all but one radiator. I'm in East Anglia and the…

Help optimising ASHP settings

The installers were in and out very quickly and more or less shrugged their shoulders when asked questions about settings, and the more I've been digging into the forums the more I've been feeling…

ASHP - disconnect between National and local government objectives
Encouraged to get an ASHP and then refused planning, even as permitted development... We've spent the last year going through the process of getting government HUG2 funding to install solar PV and a complete ASHP (inc radiators etc) moving away from old storage heaters.

ASHP how to reduce stop vibration
My neighbour has had a ASHP installed ( semi detached house ) in his front garden. The vibration that it is causing on the front of our house can be felt on the first floor in the early hours of the morning.
