yes, it is missing something. All connected without problem but the boiler is not being switched on when I increase temperature. Is this just the wrong thermostat for the job or is there something else I need to do? Thanks again

I don't know, I guess I'll find out once I connect it.?

Hi, I have a BHT 002 series WiFi thermostat to install. (Picture attached of old and new)

Hi, There was a wiki on this but it's gone so I need to ask for some help. I have an old Honeywell mechanical thermostat, 4 wires = earth, yellow switched live, blue neutral and a red live. I want to replace it. My replacement (dipping my toe in something newer) has a live and neutral input + 2...

Yes it is by platinum installer to qualify. The intergas shows 26.6kw, the atag 30.9kw in my plumb catalogue so it's the atag for extra oomph. I'm happy enough ssteel will outlast the other components. :)

flip a coin time, warranties look great on both (5 years) but Intergas also offer 10 years on HExchanger. Both HE made of stainless so be surprised if either fail. Atag ECX is sold by Atag commercial (split company now so it Atag commercial doing the A series not the ic series) ATAG is the...

Thanks to everyone for their input, it helped me quite a bit. My final choice between 2 boilers is just down to availability (and firm pricing) that are nigh on identical price and performance, I think one edges the other for reliability, one edges for efficiency but its neither here nor there...

you trying to **** into the cup or the bucket ?

bang, hit one of the nails on the head, mines located in a cupboard so nobody will ever see it.

Hi, had some great help so far and had my mind set on a viessmann 200W 35kw boiler, the range is a bit confusing but with weather comp etc and latest B model it comes in a nigh on £1650 with flue. An intergas combi compact eco rf 36 comes in at around £1200 all in (with flue) Both seem to be...

Hi, no buried pipes, I had the heating put in about 8 years ago so it's all relatively new and accessible, just have a weak boiler, baxi solo which has given me trouble although it's been well behaved for the last week or so.

Hi, thanks for quick replies :) Assume you have discounted fact that if the boiler isn't working you'll have no heating and no hot water. Yes I'm in luck, living in bungalow and had elec shower fitted in one bathroom + bathroom sinks have inline water heaters fitted as hot water took so long to...

Hi, I am soon to change my heat only system to combi, a viessmann 200 35kw Combi and I have a few layman questions to ask, I'm interested to know as I think its quite clever to be honest but wary of some pitfall. 1. There is a lot of talk of saving space which is great but what about parts like...

thank you, it's all helpful info. & recommendations always welcome :) As far as the Intergas (for anyone else who may come across this thread) "the Eco range of combi boilers can be converted to a system boiler very easily. The engineer doesn’t connect anything to the hot and cold pipes on the...

Thank you, never heard of that but will read more on it tomorrow as it's a bit confusing to me " it's a combi but you can also use it as a system boiler" But just the sort of help I needed to help me decide.

Thank you muggles, useful to know. @Gasguru , what would you suggest, I have no idea as end user how I would find out cost of ownership, my current baxi boiler is 6 years old, I'm disgusted it's already beyond economical repair and has a design fault. It's hard to nail it but I thought veissmann...

I should have checked first, although 4 years old the same Q was posted on this forum. http://www.diynot.com/diy/threads/viessmann-200w-or-100w-for-3-bed-semi-with-7-rads.334275/

Hi, Looking at the viessmann system boilers available, the Viessmann Vitodens 100-W System Boiler 30 but for just under £200 more I could have the 200-W version. Its hard to make out what the main differences are though, weather compensation sounds useful but this is just a replacement boiler...

my mistake, the link should have been this one http://viessmanndirect.co.uk/Catalogue/Domestic-Gas-Boilers/Vitodens-100-W-Compact/Vitodens-100-W-26kW-Compact-Open-Vent-Boiler-WB1B319 what design problems did you find, more for my interest now , I won't be fitting it. many thanks

sound advice, any recommendations? I need at least 28kw, the baxi was 24 but from what I now know 28 would be more suitable. this looks respectable at 26kw, I am sure price can be improved...
