ASHP costing guide
I'm looking into installing a ASHP, along with solar and a battery (that I've arranged separately).
I live in a reasonably sized, 4 bed detached that was built around 2006. It seems to have 10mm plastic microbore pipe to most of the radiators that are currently in place. I can't see if they are microbore behind the walls, but presume that they will be.
Having booked a survey with Octopus, I've since seen a number of posts stating that microbore is a bit of a show stopper, and that the costs can escalate very quickly in replacing it.
I wondered at what cost point people thought it was no longer worth it and look in to alternatives?
I appreciate it's a subjective question but just wanting to gather other people's opinions.
Also, if it's no longer cost effective, what alternatives could I look at?
Thanks in advance.
