@johnmo Thank you. I'll hope to find it in the Daikin installers manual.

Your heat pump will give you a water spec to follow. For reference this is what mine says

8680

@majordennisbloodnok If I only had a batter pudding, sadly I am only an underfloor eating defective ( apologies to Spike and the Goon show)

...

My homebrew group got the following water report from SWW Ca2+ 65 Mg2+13 Na+ 10 Cl+32 So42- 20 Hco3- 193. if that helps.

Only on this forum! Managing to combine self-help plumbing with home brewing is absolute class. "Chapeau", as they say...

Sadly, I have no idea what the answer is, but couldn't pass up the opportunity to show a bit of respect.

My install is months away but I am intending to make a few radiator changes in the bedrooms and wondering whether to do them beforehand or after the install in the summer?

Draining and refilling my present system is reasonably straightforward as it will be the upstairs rads only and I have some Fernox to replace what is lost but when the heat pump is in how much does water quality matter? Is it OK to refill and top up directly from the mains as at present? It will be water only, no glycol.

I live in the area supplied by South West Water which is from boreholes and subsequently hard (some kettle furring). At present our water has a TDS (total dissolved solids ) of 230.
