How old is the unit - was the warranty uplifted (2 years to 6 if you register within 6 months I believe)? If a full power off (disconnect from power) doesn't resolve it then it does sound like a PCB issue. Any power surges recently?

Thanks - am currently looking at separate DHW and A2A solutions from the same company for the new house.

I'm deciding how to finish two areas of my house and wondered if I can use a hardware faced plywood in both cases. Should I add plasterboard into the mix to provide some fire resistance? Or do I layer up with OSB/Plasterboard/Plyood? The Hardwood faced ply may be enough (18mm) and I like the look of wood for the finish of these features when the rest of this space is plasterboarded and painted. Both are in the same space - open plan living/kitchen area. I plan Bamboo Floors throughout. Oriel Window - Hardware Faced Ply around the inside of the window opening and then a cushion or two to sit when using this space, 1/2 dimmable led lights above for reading Window overlooking living area - Hardware Faced ply around the outside with iron on strips to cover edges and match hardwood. Inside OSB with plasterboard on top, painted, no extra lighting, just landing light. Soft bench to sit on / recline. I plan to install windows on the face and on the left side - no frames, I'll make beading to hold these myself and secure the glass inside them. The other openings will be closed off. So do I line everything with plasterboard (fireline or equivilent) and then finish or forgo the extra effort? Thanks!

Are you planning on dismantling one or just adding the heat output to warm your house? I've used one for 4 years. It does keep the Utility room nice and warm while running but you have to leave the door open as the humidity it puts out is too much for a small room to handle and like any heat pump you need a larger volume of air to draw from. Unless you are super passive it's only going to have a short term localized effect though. It does run in cycles of 2-3 hours so time it right and it could help, you just have to balance the noise with leaving the space open to the rest of the house. It can certainly help but not as much as a dedicated heating system.

Is it a single inverter with two strings? Inverters need a minimum voltage to generate power. Are they the same make and model of PV Panels? It feels like the West facing didn't hit the required voltage to generate much. If you can see the raw voltage data for each string it would tell you when they each start producing electricity. At what time of the year does this get really noticeable?

it will cost a lot more to retrofit an A2A / A2W system that you would save on the mortgage switching to a greener rate. Unless you are selling and there is a significant gain to having an A rated home, I'd say continue as you are. See what a heat pump cylinder would cost to install as though that takes longer to heat up the water it is much more efficient (heat pump is built into the top of the cylinder and needs two vents to outside). That might improve the SAP enough but will save you more money on hot water heating, best return?

I've always just used a normal bulb but switched to one that has a flame effect last time I changed it.

The slab is over 8 months old at this point and no wet trades due for some time. It's just a bit cold working there but I can wrap up more. Was curious what heating options would work best but humidity isn't a concern just yet. Maybe I do need to air the place a bit more though despite the cold if 80% is a bit too high?

No Chimney! That's another good option though. I think the condenser humidifiers have issues < 10oC.

Thanks All. I used to have an old oil free radiator, will have a look to see if it's still in storage, good idea. Didn't think about humidity - it's up around 80% currently......looks like dessicant models work best at the temps I'm at but are pricey @ €200+. Only have a 2kW battery on site when I'm not there, no temporary mains as yet.

I've a portable gas heater in storage and I was wondering with all the frost if I could use it in the self build. Everything is sealed in the house but I believe gas is a wet heat and I don't want excessive moisture build up as there is no ventilation working yet. Just would take the edge off the cold at the weekends. Has anyone done this / got any advice? Thanks!

Finally back to 100% and starting Pilates this week. Brought in the first load of 2x6's from the driveway 30/100 so 70 to go but setup some saw horses to create a conveyor belt of sorts and get these in before the frost hits hard. Not that it will go much harm to the wood but still.

I had similar site inspectors including one half way up the roof looking in the velux rooflights!! Very cheeky of them! Scaffolding is down so they have to content themselves with outside inspections from now on...!! Much colder these days, best of luck with your build too!!

Sure, there are a few self build insurance companies depending on your location. This is separate to the mortgage life insurance though as far as I'm aware, at least in my case. I had to shop around quite a bit but google and you'll find a few - they'll need details to apply and see if they will quote / cover you depending on the specifics of your build. Some of the big insurers do this and there are other specialist insurers or you can go through a broker.
