That’s a good idea too thank you John- very helpful.

Hi John- yeah small enough house and I have an 18L EV already got. 4 double rads and 3 single currently, I was thinking something similar originally, reducing the pre charge, I was going to go a bit lower again as vessel would likely end up in the hot press 2nd floor and above all existing...

Hi John- Thanks for taking time to reply. The new rad is basically at the same level as the F&E, the rad might even be a couple of inches higher than it and I have no head room to raise the wee tank- it’s in the eaves and it’s a v small attic so I do need to pressurize at least this 1 rad. I...

Thank you- I’ll look them up, are they fed the same as a rad or are they fed in-line on the supply side?(I guess that would just cool down the whole supply side so maybe not a good idea and I’ve prob answered my own question)

Hi there. Had our attic converted last year- I stuck a rad in there and ran the pipes to the hot press but never tied them in (and now it’s winter -lol) Anyhow- current system is vented F&E, so would need to seal it etc. I know what needs to be done but I’m reluctant TBH as I fear it could...

Thanks both- bit if food for thought as they say! I might just try running the house boiler at 35- that’s a smart idea- pretty sure it wouldn’t cut the mustard but I might be pleasantly surprised too. I’m no where near even considering investing in one of these.

Thanks Omph. So the ones advertised to run at higher temps do so at a reduced COP? Here’s one I see advertised: https://axebiotech.ie/monoblock-r290-heatpumps/ Too good to be true I guess!

Hi there. Will be replacing boiler in the next year or so. Wondering if anyone has experience with the higher temperature air to water boilers? Curious if they are genuinely a good alternative- 1950s semi D - not the warmest.

Curious if you fitted this and how it’s performing?

Thank you for coming back.

Hi Hllns- what system are you using to automate? I’m thinking of building a simple manifold and possibly using underfloor heating actuators- but then I’d need to automate it…

Hi there. My heating system is not zoned and I have been thinking of splitting the floors and the immersion coil with a manifold in the hot press. I can do all that handy enough. So I’m just wondering about controlling all this. Is there a good controller out there that works with certain...

Thanks all. Current thermostat is a wireless Honeywell system I put in 15 years ago- works fine but it too would need to be swapped out. I’m having a rethink and I’m going to see how feasible it would be to install or build a manifold that I can easily isolate without walking into every room in...

Oh lord it’s all very complicated

Ah I couldn’t be doing that every day
