Thanks Agile, Just to confirm.... I read the manual and confirmed with Gledhill tech support, If tank is below 30oC the pump is meant to run. It's assuming the tank is hot 24/7. And, it's the pump motor that's running/smelling hot, the pipe through it is <30oC. Would this be the typr of...

Hi Forum, I have a GH Solar thermal store 350. These have a plate heat exchanger on the side for DHW. The problem I have is that this pump is either slow coming on (meaning water wasted at the taps waiting for the hot water), Or it is running when I don't want it to. I've got...

When the heat demand is reached, the boiler goes through an "extinguish" phase and it all shuts down, waiting to be called. After the suggestion on here about pump overrun, I googled and found this thread http://community.screwfix.com/threads/pump-overrun-wiring.86665/ # 20 is the relevant...

I can confirm the boiler doesn't have a pump overrun facility. I'll get in touch with my friendly sparky (not the one who fitted it) and see if he can re-wire the tank stat or something. Cheers again, light @ end of tunnel :)

Good point, I don't think there is, but that should cure the problem. I'll check, Cheers.

Thanks for replying. Tank stat is actually set to 75 degrees. That shouldn't make any difference though - should it? The temp actually falls to ~40 ish degrees and still won't pull boiler on as boiler is still warm.

Hi, I have a Woodpecker 25 biomass boiler, but I don't think the fact it is biomass that is the issue. When running, the boiler is great. My problem is that when my water tank is cold, and the tank thermostat is calling for heat the boiler won't always attempt to start. It fires OK when...

Ok, thanks tpt. I understand the bit about needing adhesive, is the make he's suggesting recommended in your opinion? Also, is sealer and primer the same thing?

Hi forum, I'm about to fix 20 M2 of natural slate tiles, 300mm x 300mmx 10mm onto standard concrete 4" blocks internally. I got the slates at a good price, but the seller is trying to get me to buy primer and adhesive off him as well. I may well need them, but thought I'd check with...

Hi Forum, I am ready to order slates for the roof. Unfortunately Welsh are out of my price range, so are Canadians, so it will be Spanish. I have four prices from different suppliers, but I have no idea which offers best value for money, each supplier says theirs is - they would...

Thanks for reply, no urgency as such, but really hoping to be in by Christmas (Yes - I know, that's what they all say). I was hoping to save some time, but balancing time saved v extra cost.

Hi Forum, I've just began blocking my trad build house, and thinking ahead to the roof, floor area ~ 130 M2, L shaped, roof to be @ 33 degrees. Toying with the idea of using a 200mm SIP roof, but worried about the price. Would there be a massive increase in cost compared to attic trusses...

Hello everybody, Any help would be appreciated in letting me know what size cable to use for a 50m length for a filter/pump (300w ) and small water heater ( 3000W ), this is for a small swimming pool at the end of the garden which is being neglected as the kids say it's too cold. Both of...
