Thanks, going to do that. Have an electric shower in ensuite, some electric rads and will fire up the stove, going to turn boiler off for 2-3 days.

Thanks for the reply. Yes, got a lock on it. I'll give the installer a call and ask them to stop by and check it over. Thanks.

Hi Had an oil boiler installed beginning of October... -Worcester Greenstar Heatslave II external oil combi. -1200l oil tank, Kingspan Titan -4 bed detached house North Wales, walls fairly well insulated, double glazed, some areas where heat is escaping though (open loft hatch) Had 500l of oil...

I would say oncoming vehicle was more at fault, 60/40. I would think insurers would settle knock for knock though, therefore the correct answer to the OPs question is... "the person insisting it goes through insurance is a moron".

I think the stat is set to 65°. The immersion runs down about 2/3 depth of cylinder.

Ok thanks. Are there combi options for hot water that doesn't require a tank? Current hot cylinder is copper, clad in green insulating foam with an insulation jacket over top. I'll change the times on it so it comes on 1am-7am abs see if that makes a difference to amount of hw available.

Cut a long story short... the wife doesn't like the immersion heater/tank idea as she runs out of hot water showering/washing her hair. Plus she wants to free up the cupboard space that the hot cylinder is taking up. We have a 3kw immersion that runs for an hour in the mornings then half hour...

Hi Would this boiler be suitable to provide hot water for a 2 bed mid terraced house? 9kw boiler Heating is via E7 storage heaters, current hot water is cold tank loft, immersion heater, hot water cylinder in bathroom airing cupboard. There is one bathroom with bath tap & thermostatic mixer...

I ran the taps for a good few minutes to drain the heat store, the boiler fired up during this and continued to run for a minute or two after I shut off tap, I think it ran until heat store was up to temperature again (it read 63° on display).

Ok, got it set up so that the hot water isn't 'always on' and is only on when called for by Nest... however its still always on?? In the app/stat I have hot water turned off, yet using a hot tap causes the boiler to fire up to reheat heat store.

Ok cheers muggles, I'll get him back to rewire it (or do it myself if it's straight forward) and hopefully all will be ok. Odd that it has to be done this way, I would've thought having the dhw on/off option would be available under a combi set up.

Ok, set it up as a system boiler, just testing it all now. Hot water control has appeared in the app, however I can't turn hot water on/off? If I turn on hot tap & drain the storage tank in boiler, the boiler kicks in & reheats it, this is what I want to stop it doing when I'm away. In the app...

Thanks, I'll give that a go. Would that not affect how it works as I have a combi boiler, not a system boiler?

Hi Sorry another Nest thread... Just had my Nest 3rd gen fitted to new combi boiler, W/B Heatslave II external combi (oil). Nest fitted & working ok for heating, but not for hot water. There was no running hot water and no option in app or on stat to turn it on? Heating engineer has set...

thanks, will do that for now then. will get someone in at a later date for a proper overhaul as the c.u is a bit of out date now, it's a plastic casing with mcbs... 6a lighting 40a shower (be 50a soon) 32a ground floor sockets 32a top floor sockets 32a kitchen sockets 20a loft socket 20a...

From the manufacturer manual... Putting in a 50a mcb still best way forward then?

many thanks for your reply. I'll get the 50a, it's only a couple of quid. I must've done my calcs wrong, at 230v I made it 45a?

hi as per title.. is this safe? its on a 10mm² cable laid across loft on top of insulation, approx 8m run (1m from shower to 45a isolator switch, then 7m from switch to c.u). I know it should be on a 45a mcb, but it's not. never had a problem with it tripping etc. shall I replace to 40a mcb...
