ASHPs modulate just like a gas boiler.

carpet/fabric spray glue?

I'm doing this except with a coil to segregate, as the thermal store also has input from a boiler stove. Stove is on the open vented side (store contents) and all flow from the ASHP passes through the lower coil of the tank en-route to the UFH and rad circuits.

As well as Telford, have a chat with the guys at World Heat cylinders, they've no problem doing bespoke and already supply some of the ASHP companies.

A bypass valve is my strategy, but it's a wee bit noisy at the flow rates the ASHP wants to see.

What's the thread size and tube diameter @Nickfromwales ? Should be able to hunt it down

At 40c you'll need all the heat you can I'd guess, but yes the buffer will slowly drop until the ASHP comes back on.

IIRC the iVT will throttle it's power back if the delta exceeds 10c. I can't recall- are you directly connected or is there a buffer tank involved?

is that an offcut supporting it ^? Is the whole area done like that?

spray with an extension nozzle? Bit like a schutz gun for rustproofing

yes. How is air removed from the upstairs loops? Is there an auto or manual bleeder up there?

Donegal and the West Coast as far as I know

what size do you need?

Air probes generally need a bit of damping to slow their response to draughts and sunlight and such. Putting it in a wall housing should suffice, but there are other tricks used like sticking the probe into a hole in a pingpong ball...

you might need to go into the settings to see what the HW hysteresis is- what the cut-in *and* cut-out temperatures are. also does the tank have one immersion, or two?

It's good stuff- it's heavy, really doesn't want to tear, and folds and tucks well.

in Network Cell Info, look at the "Gauge" screen, the top speedo is the signal strength, IMT is the Band, and Fc is the actual frequency.

first thing to do is to comfirm which Band you local celltower is on- your phone's diagnostics might show this, or download an app like Networ Cell Info or the like.

yep, the type of liquid screed matters tho?

scapegoat?

what type of screed?

Yep, on our Cool Energy unit the main pump is under PWM control based on in-out Delta as far as I can see. Min, max, and startup speed are all configurable though.

Not all ASHPs have a pressure switch...

what's the flow-return Delta at the ASHP? Is the pump controlled from the ASHP or just off it's own algorithm?

certainly SF and B&Q have a habit of providing smaller capacity (Ah) batteries
