Thanks @stem. I think my figures were a tad optimistic! The conduit is the flexible uPVC corrugated stuff, so the internal surface won't help with the flow, there's at least 2 x small radius 90° bends in each run, and a couple of the runs are about 10m long. The runs should be airtight though -...

Hi all, I'm wondering if it's possible / practical to use flexible 25mm conduit as part of a Heat Recovery Ventilation system. My challenge is that I have a stone cottage in the far north of Scotland with a flat roof lean-to extension which I've just finished insulating and draft proofing. I...

...a little bump to see if any of you folks have any more suggestions?

I've mapped out the available tarrifs and the main anticipated panel heater usage, and it seems that the most logical way is still to favour the storage circuit when available and switch to the 24hr circuit when not (as there's only a half hour in the morning when the off-peak 24hr supply is the...

That seems to be the case, and the storage heater circuit is sometimes activated at different times of day depending on local weather conditions. Currently there are three different rates: 24hr Day: 18.89p Night: 11.25p Storage 11.43p To add to the logic fun, I've just noticed EDF have...

My apologies. When I said “one or t’other” I only meant the two rates on the 24hr meter. The storage heater circuit is independent of those. Both meters appear to be controlled by the same teleswitch but their schedules are independent. I probably confused matters by dropping Total Heating Total...

I was confused too as there didn’t seem to be enough tails for the teleswitch to be controlling both meters. But I just noticed an additional smaller cable connecting the teleswitch and 24hr meter (picture attached). It’s too small to carry much load so I assume it’s used for triggering the 24hr...

I’ve kept an eye on what the meter is up to at the point the tarrifs change for the 24hr circuit - it seems to be clean switches of the whole load between ‘normal’ and ‘low’ (that’s how the meter is labelled). So it’s one or t’other (unlike Total Heating Total Control which has the additional...

I really should have done that before posting a picture online! I'll get on it...!

I think the "flexible control" is indeed the "on/off" tariff, although EDF seem to have various versions of "flexible control". They're one of the few energy suppliers who will take on the Total Heating with Total Control metering setup which is still very common in my area. I'm on the waiting...

I've fitted some Quantumns in the rest of the house, and they're great, but we find the fan noise to be too loud for the bedroom.

The supplier is EDF. And yes, we're in Scotland. The house has recently been insulated (it was a drafty old croft house but now has an internal 'kingspanned' frame so historic usage probably isn't too helpful) and I'm in the process of moving away from old-style Dimplex storage heaters to...

Here’s the boards (storage and water at top), meters (24hr at top) and teleswitch.

Hello everyone. I’m planning on replacing a storage heater with a panel heater and I’m wondering if it’s possible to make use of the existing dual supply outlets and tarrifs? My thoughts are that it would be splendid to make use of the much cheaper storage heater supply/tarrif when available...
