RE: Failing heat pump system - seeking thoughts on a rebuild  

By Cleardene-ashp, 5 days ago

  @jamespa thanks for your thoughts. Whether DHW is fixable will be found out on Tuesday, but they suggest not so far. I’m sure it’s obvious, but what’s ‘phe’ please? One thing I will need to find out i...

  @cleardene-ashp I'm particularly interested in DHW because you mentioned it was smart. Is it a mixergy cylinder? I use one to heat my hot water overnight on an EV tariff very cheaply.

  The problem is not particularly about 'interconnectors' which are merely a symptom, (or propaganda about 'Russians'), the problem is a privatised grid run for years as a source of profit with minimal ...

  What's failing more precisely? I think the way forward rather depends on this.   I have several ideas but without knowing what must be replaced it's difficult to advise.   My instinct is to...

  A couple of thoughts: What size are the flow/return pipes pipes ? What are you currently using for DHW heating? Which part of this is at the EOL? Do you have an EV or are thinking of getting one? Is i...

  A few years ago for our new build house we put in a split system that uses one bit of kit for the DHW and another main ASHP for the underfloor heating. one part of this system is failing and the point...

  @tim441 Puts even more reason behind any proposal to have battery back-up in one’s system doesn’t it? Anyone else seen the ‘press release’ on their Tesla app about the one millionth Powerwall having b...
