Ah, sorry for misunderstanding. I don't know if the pipe in the bottom-right is new - I don't have previous photos of that wall and didn't think about what was there before. The previous boiler may well have been non-condensing - it was a Ferroli F30, plausibly from 2004 when I think the flat...

Ah OK, sorry for misunderstanding. I don't know if that pipe in the bottom right is new - I don't have photos of that wall and don't remember what was there before. I believe the previous boiler was non-condensing - it was a Ferroli F30, plausibly from 2004 when I think the flat was built, and...

Thanks. Which model is that for? I looked up the instructions for the ecoFIT pure 825-835 (not sure if this corresponds to the boiler I had installed - I only know its an ecoFIT 25kW) here and it doesn't seem to mention sealing the flue on the outside (for the flue set up on p.12). So I wonder...

If it's sealed on the inside alone, would it be compliant with regulations then? Does it only need to be sealed on the outside if the "mi's" say so?

Thanks. Sorry but just to check, what are "mi's"? Manufacturer's instructions?

Thanks. Do you mean it currently doesn't appear compliant with regulations if the new flue isn't sealed? What does it need to be 300mm away from? The new boiler is a Vaillant Ecofit.

Hi, I recently had a gas boiler replaced in a 2nd floor flat. In discussions with the company afterwards, I found out that they had to drill a new flue hole (I wasn't there when the work was being done - it didn't seem like they would have taken the initiative to tell me!). This hadn't been...

Thanks, this is a helpful perspective. The fireplaces below are blocked off. The dripping isn't causing noticeable water damage as yet, but we had the chimney inspected, which identified the cracks in the flaunching as the likely cause, and so we're debating whether to get that fixed to prevent...

Thanks for the replies. Some flat-owners think it isn't clearly worth the effort and cost. (We have share-of-freehold and need to come to a consensus.)

Hello, I own a flat in a block of converted terraced houses. One of our chimneys has been found to have cracks in the flaunching - see attached photos. The symptoms so far are fairly frequent dripping of water down the chimney when there is heavy rain (about once every 3-4 seconds), which seems...

Thanks for the further replies. I've deactivated the fan now and will look into getting ventilation to the outside installed. I checked that other fitting and it's disconnected, so I don't think that's a problem, but thanks for pointing it out. Astute observation about the coal dust - this is...

Thanks again. I've attached photos of the fan amongst the insulation and how it appears at the edge of the loft with the insulation pulled up - the sun had gone down, but it seems to be all closed up anyway.

I saw this after I wrote the above - the fan isn't covered by insulation. The fan is one or two feet from the eaves. When I looked before there only seemed to be daylight from a few holes that might be vents in the tiles - the loft is pretty dark overall.

Thanks for those replies. Sorry I should have said that the fan is in a bathroom. It sounds like it can't be assumed to have adequate ventilation up there. Would it be clearly noticeable if it were getting too humid after a shower, or would there not be a way until damage had been done to the...

Hello, I just had an extractor fan replaced by an electrician (edit - it's in a bathroom) and found out from him at the end that it's venting into the loft. (I've only just moved in, and so I wasn't aware of this.) I've done some searching and found out that this poses risks for condensation...

Is that how long ago they stopped making this model of boiler? Its age is something I have wondered about because it was here when I moved in. It's not had any other problems to date, though.

Yes I did try calling a few others - one would have cost about the same as the original guy's new price, one wasn't interested and one said to send him details and he'd get back and I'm still waiting to hear anything. So I don't think I'll find a much better deal - but at least I found someone I...

Thanks very much for your replies. I talked to him again and he said he'll remove the extra charge for draining and refilling, so I figured I'd just go with it to get it done with and I'm not sure there would be a better deal from anyone else.

It's a Ferroli F30 - I wasn't sure if I'm allowed to mention the brand here.

Hello, recently my central heating stopped working and an engineer diagnosed the problem as being that the electrical connection point on the heating pump has partially melted, presumably due to the connection being poor. The pump is inside the boiler body. He recommended replacing the pump and...
