this keeps being repeated, but is it actually true? Not in the case of the gypsum Hemihydrate product we used.

I had a good nerdy exchange with Chris, seems sound enough.

going a touch off-piste for that- https://coolenergyshop.com/collections/inverter-heat-pump/products/cool-energy-invertech-ivt9-air-source-heat-pump-ce-ivt9 the full suite of Carel control gear rather than the normal Chinesium-looking fayre swung it fo me.

Michael Berryman, attni.

So spending more money time! Heat pump ordered, Air test booked for Thursday.

the insulating powder in the elements is hygroscopic. Same with Pyro cable.

Is the meter connected the right way round? the LED should flash during the day and be on constant overnight.

Can't be bothered, so maybe @zoothorn can confirm for us? And maybe take some nice piccies of how all the kit is sited in the room???

but it's not AFAIK, I think we discussed it's siting months back on another thread?

I wonder... if the thermostat controller thingy is in the small room with the cylinder etc in, could the systems fuzzy logic be incorrectly presuming the heatup time/ energy input for the rest of the house? As in, using the weather compensation etc it's dialling back the flow temperature because of the rate-of-rise in the room with the 'stat in...

The semi-rigid ducts are smooth-bore.

If the rad is really undersized, how do you kow that the rad + oilfilled heater really *is* enough heat for the room? Just do the measuring we're asking for.

put one of your thermometers on the flow and return from the "boiler" box thingy.

loss through (new, insulated?) pipes is very small compared to that of each radiator. Sadly you have *no idea* of the 55c bit, and age is nothing to do with it. That's why we want you to actually measure it. Maybe the flow temperature sensor in the unit is duff and reading 10deg out? YOU DON'T KNOW YET.

No digger or dumper on site to ferry it?

yes!

shouldn't an upstand have been formed in the lead around the hole for the flexi?

You paid HOW MUCH???? each? Please tell me that's a typo...

the loop with the missing actuator, the white cap is a manual on-off.

Is the bypass loop actually turned on?

Miele lab machines come with the deflector in the install kit.

If it's what you intended then surely it was designed, and so can be implemented? Regardless of the current situation... /someone did sign off a design for the EIC I presume.

certainly a dry ridge, but can't tell if it's vented or not...

so many switches...

perhaps calibration is all that is required as the self-heating offset is going to be a pretty stable thing I'd guess... / I'd opine that a good old-fashioned mechaninical stat with accellerator could very well read higher than ambient for the same reason.
