Surely @Peter if I’m using 220kWh at 21p/kWh then my weekly cost is £46.20. If I used e7 at about 8p/kWh then my weekly cost would be £17.60 saving me £28.60/week. Nigh on £1500 a year. I’d need about a 35kWh battery I guess. Any idea how much they cost? Could prob get away with a 15-20kWh ish battery buy running appliances etc overnight. Just thinking out loud! An option for people who don’t want/can’t have solar?

Silly question perhaps, but given that the cost of e7 is so much lower, would it be worth just buying some batteries, fully charging them on e7 and using that during the expensive times of the day? Wouldn’t that work out more effective then solar panels during the over production in the summer and under production in the winter?

@tonyshouse even with all those edges? I’m happy to spend time cleaning the sprayer, I just hate actual painting, especially cutting in. any recommendations on brand? Thanks all!

@epsilonGreedy our heating is LPG, @SteamyTea we have 1 EV and 1 ICE, soon changing to 2 EV. @ProDave we don’t have horses…. Should we build a shelter ‘just in case’?

We have a number of rooms to paint including ceilings between beams. Our plasterer recommended spraying because you only need to mask once rather than cutting in each coat (min 3 coats - onto fresh plaster). is he right and if so, which sprayer should we get?

Thanks all, guess 4kW is what to aim for then and use it to mitigate costs rather then remove them. The concept of this system seems very straightforward and guess would save about £800/year (21p/kWh)? Am I missing something? Is it too simple? Am I paying more for the privilege of simplicity? https://www.roofgiant.com/flat-roofing-solar/plug-in-solar-4kw-4000w-diy-solar-power-kit-with-renusol-console-tubs-for-ground-or-flat-roof/

@SteamyTea thanks for this breakdown. We live on the side of a south facing hill with a bit of a paddock to the rear (above) the house so hopefully they’ll be closer together because of this. my wife is adamant that we won’t have them on the house because of the aesthetic - it’s a Cotswold stone cottage built in 1801 so m almost inclined to agree with her. so by my calculations I’ll need about 11kWp which will cover 48sqm and a DIY kit cost about £4500 (using @Temp’s guidance) + instalation. This would save me about £2000/year on electricity bills so be ‘making money’ in y3. is this right? We don’t have 3 phase electricity.

Hello all, Please forgive my ignorance and mistakes herein, however I just can’t get my head around this PV stuff. Were currently using about 220kwh (or kWh or whatever) of electricity per week (yes high) and will likely increase when we change our second car from ICE to an EV. We’re on a standard EDF tariff after our previous supplier went bust. No E7 or anything like that. We have space for a ground mounted PV I think. What size should I be aiming for? I’m not fussed about FIT or anything like that, or storing excess in batteries/thermal store (unless anyone can show it’s a simple thing) but am Reasonably happy to install myself and get a sparky to connect/commission. The questions are ‘how big a rig’ would I need and roughly ballpark £ figures? sorry if this has already been covered. I feel like I have scrambled egg between my ears!

This is what I have from the back…. Doesn’t go anywhere by my calculations?

thanks @ProDave, good shout - I’ll have a look. Yes all wireless here! Retrofit so not chasing in cables everywhere!!

I’m about to start wiring in the control centre for the UFH. It’s a Hetta system that seems great so far except the wiring diagram sent with it doesn’t quite match the box. I can’t find an earth point for the incoming mains and I’m fairly sure it needs earthing. Along with the manifold pump which seems to only have connections to a live/neutral with again no earth. Is this the earth for either or both? tia!

@JohnMo thanks! I’ve just found the instructions showing how to switch it around. RTFM.

Morning BHers… In all of the pictures/diagrams I have found, the UFH manifold has the pump to the left when looking at it. I want to arrange ours so the pump is to the right, as in the pic below. The only issues I can see is that the thermostat thingy on the mixing valve would be at the back not the front. Am I missing something? thanks!

Evening all! Just a quick question…. We’re about to upgrade the kids bathroom (the old one is about 30 years old!) and it’s an easy straightforward job. Except…. The presence of a macerator. Are there any alternatives? Putting in a ‘proper’ soil pipe would be tricky as it’s at the back of the house with the main sewer at the front and would have to go around the conservatory and down 2 level changes… I know they’re a nightmare, but do I have any real choice?!?

We have been let down on our tiling job. 13sqm limestone tiles 600x900x15mm 8sqm ceramic herringbone 100x600x9mm ditra matting to be laid over UFH. we will supply: - tiles - Adhesive - matting - grout - sealant everything on site already, would like it done before the 29th oct. £1200 cash. Comment or DM me for more info! Postcode: GL6, near Stroud, Gloucestershire.

Is there any insulation in existing screed? If not and you just add a retrofit system then a lot of the energy will go into heating the slab rather then the room. Think it’s prob a dig out and start again, which will be much more expensive I assume. good luck!

I have dewalt and v happy. I bought the drill with 2x 4Ah batteries about 3 months ago and despite lots of screwing (about 1500 70mm size 4s!) only charged the battery once. good luck!

Ah yes, we had this one on order in black but it was discontinued about 2 days after we ordered it. The black one was £780 and think we paid £750 from marks electrical for the silver one.

We’ve just bought a Samsung which is lovely. It’s also compact too, which gives space for a warming draw underneath if in a standard base unit. Samsung NQ50J5530BS It’s not the zanussi, sorry, but it is nice!

Sticks like sh*t mostly, the occasional nail if really needed.

Ok, so stupid question time, the external corners are still mitred? I can’t see this method working on externals!

Jeez, but sure I have the time/patience/skill for that!! I was just going to measure each joint and adjust the mitre to suit…. Is this terrible?!?

Think we’re using 3mm… does that sound about right? Apparently they can’t be too small because there wouldn’t be enough movement and the grout might crack? Or is this bullsh*t?

Thanks James, what do you mean by scribe the internal not mitre? Noobie here!

I’m looking to buy an electric saw thingymigiggy for cutting mitres on skirtings amongst other things after a chippy quoted £30/m to attach the 30m of skirtings I already have. (Nearly had a heart attack at that quote!) any recommendations or things to watch out for? Skirtings are 194mm tall and 18mm thick, will do other things too but skirtings are the primary thing for the moment.
