we went to a square section nylon filament and it's incredible! So much nastier than the ordinary round stuff, even half inch brambles are dealt with very easily. Seems to last longer too...

I recognise that ASHP... Just screw the isolator to the side of the unit

@ProDave Take a look at your prescription, specifically the "Add" number. that's the magnification the optician recommends adding to your base correction to get the reading prescription. Go to one of the online providers, I use https://www.selectspecs.com/ the lab is in Hong Kong but the service is superb and they're cheap as chips; and when you're typing in your prescription, make the Add 0.5 or 1 less. Or both, they're so cheap, lol.

just don't leave any visible marks.

You pay to uplift a pallet, I'll put two on it...

what a palaver. Merchant's, £15, done. :shrug:

^ that's pretty much what I'm doing with my TS @SteamyTea. HP coil buffers the system/tank to at least heating flow temp, but can raise the whole tank to DHW temps if the upper/lower immersions haven't done that using the PV.

Fan will only run when it's actively heating. The fan on the better units is modulated and will change speed to suit the load.

you didn't annoy the plasterers did ya? Polished up with a plastic bag will do this...

SDS drill then SDS chisel.

Buy loadsa 16mm fittings and use it for your first fix plumbing too? I thought about it, but the ease of working in 10 and 15mm put me off tbh.

Toasty telly!

Inverse, ST. Bog-standard weather compensation, in other words?

If you're installing it yourself why would you pay someone £600 for walking round the house with an anemometer?

nope, don't need handles. Ours is pretty big, a mooring bollard might be of more use...

tiny leak. each time pushes a wee bit of volume out of the pipe til there isn't enough to send the signal

It's possible to get great design at affordable cost with no percentages. You could do worse than spending a few quid to peruse the designs on https://irish-house-plans.ie/ or the like. Shaun did a great job for us...

Is the black plastic over the felt and battens still there? That would create a lot of ponding if so.

Digger with forks on?

I've just had a look at the Worcester Bosch website, and interestingly, according to the ERP label their indoor oil boilers are 54-60Db yet their outdoor one is somehow 0Db. Hmmm...

precisely.

I'd be more concerned about Brinelling of the bearing surfaces off-road than simple loading.

@Dave JonesNo they aren't. Cite your source.

But how do you know when the oil unit has reached setpoint? Short of going and checking if the burner is running? Rads will be putting out noticeable heat well below that. The oil unit is totally uncontrolled, the ASHP will only be putting out it's full 12.5kW *if* the heating load keeps the return temp low and as previous it wants to keep the flow deltaT within limits as well. It's the same house with the same heatload. The oil boiler will heat it more rapidly.
