ASHP & triple glazing

[Joeboy]

Trying to be as honest as possible here and take images at as close to same environment.

This first TI photo was taken after we'd pulled out the gas fire and all it's gubbins. I'd blocked the gas pipe hole up through the floor but that was all. This spot is just to the left of the now blocked gas pipe hole.



The second TI photo is today. I think that's about 5 days since we started. In that time we foamed the internal bottom rail to stop communication between underfloor and wall. We've filled the wall cavity with vermiculite and I've just caulked the gap between the bottom of the plasterboard and the chipboard floor.



The path remains clear from top of this wall into vented loft space.

Great to see those figures for comparison. I have just dropped the heat curve back to 0.6 which was it's original setting from Bartek. I did this as the 0.7 setting shot the temp up quickly. The active setting should give the unit more scope to do it's own thing? The sensocomfort is in the front lounge as we didn't want the wbs in big lounge to affect the rest of the house reading. This was our readings just before I dropped from 0.7 to 0.6 heat curve. Are you running active or expanded Iain?

That makes sense with the Sensocomfort, I'm running in "Inactive" mode and have been since install.

That work on the wall looks to be paying dividends.

I may have to read further or at the very least test that out myself. Why4 did you choose inactive, I know there'll be a good reason?

The wall is my wee happy place at the moment.

I'm pretty sure it was set at that during commissioning with a 0.6 curve and all I've done is alter the curve to suit the house temperature.

Ah OK, not sure why this system was set to expanded. I'll keep an eye on it and see how it performs in active mode. Once I get an understanding of it I'll try inactive. As far as I can see, setting the heat curve is akin to putting in an engine limiter. It does make me wonder whether the compensation modes can exceed that limiter depending on the weather.

Last night in expanded mode and 0.4 heat curve this did not happen. Tonight it's active mode and 0.6 and we'll what tomorrow brings. I do know that 0.4 & expanded is no use at minus 9!

Going by the info from the link you posted "Active" should do as you hope:
When the Active menu item is selected then the control system now considers the reading of the thermometer inside the SensoComfort controller. The basic control still uses the weather compensation determined by the heat curve, but if – for some reason – the standard weather compensation algorithm is not matching the heat loss, then this will be reflected in the internal temperature. This mode allows the system to respond in order to maintain room temperature.

Part of your problem could be that having the Sensocomfort in the front lounge it is not responding to the temperature of the big lounge where you have the largest expanse of glass and therefore greater heat loss. If the Sensocomfort is freestanding try moving it into the big lounge before you go to bed.

Aye, we're all over the place the noo! The 3G will hopefully have a massive impact on the Big lounge. Stinsy said so about 4 years ago! (3rd pane warm to touch). Senso is now out in midhall, that's centre of house and where I hope it will end up living. HP defo makes ye focus and fairly shows the flaws

I'm really glad it doesn't get down to -9c here, the lowest its been over the last few days is about -1c, seems you're heat pump gets through a lot of electric at those low temperature, but still not too expensive when you factor in the long cheap period overnight, then however much the batteries can carry you through the day - we used £5.60 worth of gas yesterday including the SC.

My heat pump has certainly been using up the electricity today, so far 70kWh used with average temperature of -6.8C COP of 2.32, batteries down to 22%.

Good slots tonight pal.
£3.78 run through ashp in the last 24hrs. Clean, clean, clean.
133kWh of heat for that cash. -6 the noo.
