Will there not be gable ladders anyway? Surely you can loose the difference there...

I'd expect a composite door to come in it's own frame?

temp difference= hysteresis. reduce that a bit it'll cut back in sooner stop temp difference is an allowed overshoot, more useful for heating as gives more time for the unit to ramp down without shutting off immediately

User Mask, unless you're using time controls in which case it's in Timezone

which machine, and do you mean the actual setpoint or do you want to recalibrate the probe?

assuming the thermometers are both reading correctly, that should be a toasty hot floor...

no purge cycle or anything like it on the iVT. Yep just fire it up and your bottle valves will sort it. Only open the isolators on the UFH manifold when you're sure the hissing has stopped tho... / worst that can happen is it trips a flow error

Another vote for a wee splash of glycol, here.

didn't @Conor do this?

they have their uses. Do you need to silence the actual airflow, or isolate pipe lengths from each other to reduce propogation? Quite different requirements...

Had something similar a couple of months back on our Coolenergy unit- one of the three spade connectors on top if the compressor had loosened and burnt. The codes on the Carel unit were for starting fail and overcurrent which had me fearing the worst- shorted windings. Might be worth a peek under the plastic cover atop the compressor...

push them in afterwards

^ electronically commutated, no capacitor. Doesn't look like it's got any unblocking mode unlike many modern pumps that'll attempt to shake themselves loose if the rotor can't move?

what type of pump is it- fancy multimode thingy with digital display, or old tech with a 3-speed switch and a starting capacitor? Is the water well inhibited?

I'll throw a curveball. 9kw ASHP plus thermal store, thermistor probe halfway down the tank...

umm, that's probably more like 3.5Ah. I've just bought a motorcycle battery about the same size and weight..

still plenty using neons

@Talaidh where in the world are you?

looks like the same flipper as ours. If so, there's a wee screw holds the top cap on, as a pivot

I work in and around both healthcare and scientific research. There is NO DOUBT that poor decisions were made during the rollout of the lockdown. Could things have been done differently? Absolutely. The messaging was horrendous. So many people across the nation suffered massive loss- of family, personal health and mental health. Thus the Enquiry. But the worst thing in my view was indeed the outright disrespect for the nation by those in power who partied, and those that saught to make massive financial gain eg PPE contracts etc. I would love to believe it was all some cynical game, and would have bar one thing- the lead researchers locally who were used as talking heads on the local news etc, who I've known for decades and trust with my life when I'm in a cat3 area servicing their equipment- were sh*tting themselves. These guys who are trained in the safe handling of risks, were scared. Why? Because the normal rules didn't apply. In the lab, you protect yourself, work carefully, clean down safely. Jo Public was walking around with it in the open air...

cut a big hole in the chassis of the unit and let the supply air percolate through it?

B&Q used to keep polystyrene in stock, dunno about nowadays. Does it all need to be window-clear or is twinwall an option for any of it?

I wouldn't expect McMordie's to be the cheapest source ever, but they *do* know their stuff...

smells like a broken wire/ loose connection somewhere in the fitting.

Isn't it nice to just try and tread lightly on the earth?
