Hello
What are your views about putting a 210lt unvented cylinder up in a loft?
Customer has traditional open vent at the moment but wants that gone & indirect unvented in the loft with a new compact boiler up there?
Would the weight of the cylinder be ok? I’ve seen people reinforce up there to spread the load.
I thought I’d ask before I speak to my mate as he’ll need to do the boiler.
Cheers all

Cheers all In my humble opinion I’d probably look at reinforcing as 210kg plus the weight of the cylinder (which won’t be much) is quite a lot over day a square meter |

I was just looking at horizontal ones to spread the load more.

It would have to be supported over a load bearing wall and it would be fine,  |

To ask a dafty question does that mean you don't need to be gassafe plus unvented to install one ? Or just that lots of people do without the ticket?
Only asking because its one of those things I'd love to learn more about and possibly install / explode the loft.

I've seen a set up similar to what your after Rocky and they had a full platform constructed - heavy duty joist across the loft joists with a base drain as the original tank had a slow leak and cause damage to various areas of the property, as they had original tank only on 1" board spreading the weight across the loft joist - the movement pulled the pipe work apart.

Why bother??
An Unvented May deliver 20Ltr/min, depending on incoming mains water Flow Rate & Pressure, you’re storing a load of hot water why?
A 40KW combi will deliver 16-18Ltr/min, no storage & no weight problems. There’s a lot less hot water used in homes now, cold fill Dishwashers & Washing Machines, plus, most people have showers at 40-44degrees C.
Most Builders are fitting large combis, even in 4-5 Bedroom houses.

that makes sense to me Dick, I've always been a combi worshiper, heat only the water you need and no waiting for cylinder recovery for the next shower/bath, its a win win situation,  |

Currently got a vented but its a large 200l well insulated one. Compared to the previous that was also furred up due to hard water (I now soften the water) it is much faster - maybe 2 or 3 times.
Still I do see the point about the combi. That said, if you did have a big house and wanted a power shower, are there any combis that can say do 30 l/min ? Maybe you'd need two of them?

combi's and multi hot water outputs have always been an issue, unvented will deliver better multi hot water outputs but. only at a premium price and not always worth the extra, Management of the house is the key, don't all shower at the same time, |

I guess it a generational thing, we’d a Bath on a Sunday night - if we needed it or not. But kids these days can have two showers a day!!

My only problem with combi is when it goes down you lose heat & hot water otherwise they’re ok.
