Still researching this issue. Have been to odpm web site. How can you assess a building for the lowest cost option for installing a condensing boiler yet ignore existing fitments or the owners wishes. I certainly don't want a boiler in any of my bedrooms as I'd lose valuable existing cupboard space and I imagine there would be additional costs in connecting up to existing pipe work. Where does this government get off saying that I don't have a say in what I do in my own home. If I was younger, I'd emigrate to somewhere with a more sympathetic government, like Zimbabwe or Iran!

I've read Approved Doc J. I've read the condensing boiler assessment procedure. Due to the type of property I have I think I'll be struggling to install a condenser. However I feel that the info I have gleaned will help me weed out the good from the bad when it comes to getting quotes. I'm going to bed now. I have a headache from all those regs. Don't know how you guys manage on a daily basis!

spongebob.

Good news and bad news.

The new regs for condensing boilers have been re-worded Grin

Wall terminals should be sited a minimum of 2.5m from a facing wall, fence, building or the property boundry

More restrictive requirements apply for a wall terminal that discharges over a public footpath.

e.g. a minimum height to the underside of the terminal of 2.1m.

for more information see.

scruff. I've read all that. I could get the height no problem. The issue now is the boundary matter and I'll have to make enquiries to clear that up. At the rear of the property the set up is as follows, back door, footpath, access road, communal lawned area. Although the local council do the grass cutting I'm almost certain that my boundary extends into it . It's all a bit of a pain really. One additional note. I e-mailed this info to a mate. He paid last year to have his conventional boiler moved from a bedroom into a out house. Now if he changes to a condenser he won't be able to use his drive without considerable flue extension. I've still got the head ache by the way.

"I've read Approved Doc J. I've read the condensing boiler assessment procedure."

Please be clear that rules in the condensing boiler assessment procedure do not apply to the actual installation. Only doc. J applies, together with manufacturers Instructions. Figures given by scruff above are not applicable!

As you can see, it's all very confusing. If it's any consolation, we're all getting thoroughly pissed off with all the new regs., etc. It's just escalated beyond the threshold of what your average heating installer can cope with. End result will be more and more people saying "sod it" and ignoring it all. Well done John Prescott.

Just curious... why is it harder to install a condensing boiler than a non-condensing boiler? The condensing gas boiler we have is quite small and there are no extra pipes or anything so I'm slightly confused as to why you think they are harder to fit in?

Perhaps I've missed something - I'm no expert!

Well now you've got me thinking. We don't have a pipe for the condensate. Humm I'm beginning to wonder if our boiler really is a condensing boiler!

It's a Bosch/Junkers Cerastar but I've only found limited data for the model we have on the web...

In dutch it says...

In sommige ruimtes is het (bijna) onmogelijk om een luchttoevoerbuis te installeren. Een open toestel biedt dan uitkomst, mits er voldoende ventilatie is. Als u kiest voor de Bosch Junkers Cerastar hoeft u geen concessies te doen aan uw comfort. (verbeterd rendement uitvoering)

Which I think says...

In some spaces it is (almost) impossible install a ventilation pipe (condensate pipe?). An open appliance brings then help, provided that there is sufficient ventilation. If you choose you no do concessions to your comfort for the bosch Junkers Cerastar must. (improved output implementation)

Well translated! But they're talking about the air inlet duct to the boiler, which is not required if an open flue appliance is used. Nothing about condensate pipes. If it doesn't have a condensate drain, it ain't a condenser!

8.13 pm - just done some research. I'm almost certain that the Cerastar is not a condensing boiler (brennwertgeraete in German). If you were sold it as a condenser you've been conned. Roll Eyes
