Any advice / opinions please anyone?

House built in 1979. I believe it was built with the PVC sliding door which we've recently replaced for an aluminium door (as part of a much bigger project). As per the photos, there is a gap between floorboards and rear of door (threshold?) and I can see down the cavity. The DPC is two courses...

Holy ****! If those things didn't just work off cold water, I'd be ordering one.... :lol:

Ah, but maybe I just meant I was going to personally mail him as in email..... 8)

PM on its way....

Anyone?

OK, I've gone through the saga of repairing my clapped-out Sime Super 90 plus (90,000 BTU) combi by changing the DV. It copes, just, but I think there's more severe problems because it takes ages to heat DHW. Plus it's massive. And I thinks it's dying. So, because I trust the majority of the...

Right, I've ordered a new DV. They're about £24 + VAT from BES - I know it isn't genuine Sime but the feeling from these forums is that they're up to the job. Having said that, I fitted a new BES DV last November - it looks like I got it from a dodgy batch because the CH was still heating up...

Hmm..... don't honestly know. I'd guess that the boiler and rads were done at the same time (guessing 20 years ago). Presumably the pipework was done at the same time (is this a logical assumption?) Fitz - do you fancy making the trip to Oldham or should i contact a local heating engineer?

True, but with a new DV I might be happy with my current boiler. And the BG quote was errm..... a little more than expected. When i can get a new DV relatively cheaply, i'd have to be fairly narked off with the old boiler for it to cost me over £3K! Bob

>>lol, but you asked them for a quote Good point.... but it would have been refreshing to hear him say: 'Actually, I've got a much cheaper and easier solution than buying a new boiler.....' Did you see that pig just fly past? ;-) Bob

Thanks again all, Yes - 90 is 90,000btu. And yes, the meter goes at about 1 cu ft every 36-37 seconds. I think I'll get someone out who knows what they're talking about (and isn't targetted on selling boilers!!!!) to see if my current system can just be overhaulled and tweaked to run like...

Cheers, if at present the 15mm pipe goes (approximately) 30m, and I got it replaced with 22mm pipe going (approximately) 12m, will I actually notice a significant difference to the DHW capability of the SIME boiler (once I've had the DV changed)? Even with a fully working DV, the DHW took...

I've currently got a Sime Super 90 Plus boiler. It's big, it's old and the DHW is rubbish. Having said that, it needs a new diverter valve (I replaced it last year, but the replacement (brand new) was also faulty - I didn't return it because it was better than the old one, it was only £25...

Captain Handy Andy?

Hi, When did you buy your DV from BES? I bought one for my Sime on 13th December and have the same problem as you - CH flow gets warm when running DHW. I've not stripped it yet though.... I'm just wondering whether we've both got new DVs from a suspect batch? Mine is the 17092 (BES part...

It's definately illegal - there was a similar situation when my Uncle had a Matchbox and a Hot Wheels which did the same. They all got 15 years each for perverting the course of justice. :lol:

Thanks Chris, There is definately something wrong then.... from cold, when I run the DHW the CH flow pipe heats up more than the DHW one!!!! And the diverter valve is only 3 weeks old! If dirt is the cause, is this valve something which can generally be taken to bits to clean? Whilst I've...

So, is this right? Is it natural that my CH flow pipe warms up, or should it stay stoney-cold? Bob

Hi, I think the question is self explanatory.... The boiler is a Sime Super 90 Plus combi. It has a brand new diverter valve. When the CH is switched off and the pipes are cold, if I run the DHW until it warms up, the CH flow pipe also warms - is this right? Or is my new diverter valve...
