Faye wrote the house name on a slate with a paint pen. I screwed it to the wall. Done

Haven't you got a sign downstairs saying No1's only?

My PV cables go between the overlap in the felt, that is just lazy, it would not have taken long to thread them through. You could put a loop in the cable to stop any drips reaching anything electrical. I decided against putting my inverter in the loft, due to the high temperatures in the summer months. Even with it in the coldest room in the house (the garage) the cooling fan still operates during the summer.

Don't do it mate. They only give you a false sense of confidence ?

That's Ben Law's house that I mentioned and linked to earlier, I think.

Just connect it to a boost regulator. One like this: https://www.ebay.co.uk/itm/MT3608-DC-DC-Voltage-Step-Up-Adjustable-Boost-Converter-Module-2A-in-UK-FAST/163769024236?hash=item262164feec:m:mUxc03WpRU3Xg2hZo256t8A would accept the variable voltage input from the panel and could be set to give a fixed 12 V out.

Following on from what @Ed Davies said about needing a height difference to get theromsyphoning going, and rather than having a largish tank of water above the panel or tubes, could one fit a heat exchanger above them. Might even be possible to fit that in the loft and not use water as the transfer medium.

RWelcome. Once the laws have changed, you could grow a cannabis plantation and suggest you need to be on site to defend it ?. Feed the weed to the enforcer and they won’t be able to remember where it was. We had a small listed manor, and they came once, then never came back for the next 30 years. When w3 asked them to come and advise when selling they could not even find it. We could all come and visit. (Serious people along in a minute)

Extraction is constant if connected to your MVHR. Even with mine (no MVHR), pan extraction starts as soon as the main extract fan starts, then carries on whilst you're "sitting", flushing and for 15 mins from the moment you start the fan. It's constant if the room humidity is above 65%. Get your bco to come sniff mine, with and without the pan fan going!

No seals are impacted at all by doing this. The idea is simply to ventilate the air space in the pan, and this is always directly connected to the flush pipe, and also to the air space above the water in the cistern. I suggest the BPC people need to go and take a look at how a toilet works...

Really depends what @SRP means by 'project manage' and how insulated / engaged they want to be in the build process. It's a sliding scale of engagement really and there is no one size fits all model - very dependent on your attitude to budget, quality and time. Are you likely to be really stretching your budget, more or less comfortable with the costs with a buffer or are you awash with cash? Do you really care how things get done or will you have very specific ideas about detailing during all stages of the build? Can you be disturbed at all during the working day to take/make a call? Can you spend some of a lunchtime and evenings / weekends on the phone / internet? Can you work from home a few days a week or get to site ever? Does your build need to happen asap or can you take a bit more time (usually this depends on your accommodation situation while building, if you're living on site in a caravan then you're lest cost sensitive to overuns etc..) You need to check with your architect just how hands on they would be as a PM - frequency of site visit, scope to make autonomous cost / quality based decisions etc. You will need general site management also, opening, closing, taking deliveries, H&S etc. Then you need to decide how sub contractor / materials decisions are made. Do you want to approve? Leave it to general contractor? Have Architect manage tenders etc? A general contractor will run your site and will hire in subs but they won't necessarily make great purchasing decisions for you or hunt for best prices / quality etc - they tend to stay in their comfort zone (usual subs, suppliers, decent credit etc) and if it's a fixed price deal, they will retain savings / absorb costs. They will do things the way they usually do things so if you have some very specific requirements in design or quality (e.g. airtightness, shadow gapping etc..) then you will need someone to be more hands on with the delivery of those items. PMing it yourself is potentially cheaper - depends how much time you can commit and how engaged you want to be with the decision making. We both worked full time but I worked from home mostly during the build and we lived on site so was able to see what was happening few times a day but the majority of PM time was evenings and weekends to source materials & pricing. Needed to field occasional calls during the day for schedule trades & deliveries but if you want all decisions to be run by you then you'll have a similar level of disturbance. We chose all subs and materials so saved 20-30% on the QS plan that was originally presented to us by a professional PM (plus his fee) i.e. to get the same quality (maybe) from a hands off turnkey single contractor would have probably added 20-30% to our budget.

I've a foot square panel that does about 10W, but have a 6v wallwart in parallel to ensure it starts in low-ish light. All through the solartwin differental controller

just needs a pump -will not work without a pump only thermo syhpon system i have seen was in kenya it was a 1000litre corrugated tank with a transit van radiator on top in a cold frame on a slant it worked by thermo syphon no probs --but that was on the equator and sun all day long

Thought I'd update this thread with our experience to date. So far this month we've had 15 virtually cloudless days (out of 21) including a run of 8 consecutive such days. We've left the Sageglass in auto mode and it has worked extremely well in restricting the solar gain and effectively regulating the indoor temperature. Granted, the sun is relatively high in the sky now and approx 25% of the south-facing glass is shaded by our 50cm soffit overhang, but I'm pretty confident the Sageglass would cope even if we'd had such a run of cloudless days earlier in the year. So far, to coin an old Honda marketing strapline, it just works! Edit to add: by the way, the privacy element is fine during daytime when the glass tints as it reflects like a black mirror when viewed from outside, but is far less effective at night when light are on inside. Suffice to say we now have blinds at the bedroom windows!

Full price at the time of ordering was circa ₤1k/m2 for the rectangular IGUs and double that for the shaped ones, plus about ₤2k for the control panel, switching, etc, and another ₤2.3k for shipping and commissioning, but I hasten to add I paid nothing like those numbers and you have also to deduct the cost of the glass that would have been supplied by Internorm.

The snag is that the heat is mainly available when you least need it, when it's sunny and the panels are generating a lot. In winter, when you could usefully use the heat, the chances are that the panels won't be producing much power, so the inverter won't get very warm.
