vertical unvented cylinder in empty loft

moneyspending

Plumber suggests there is a risk of cylinder toppling as there is no supporting wall around tall cylinder in Loft. Hence he recommends horizontal cylinder.

I am not quite sure as havent read anywhere this!

I am sure he can support vertical cylinder so that it does not fall?

Probably sensibly thinks that you will use it to store objects against - I can't see it toppling over by itself, but could fall over with some pushing or with weight of other things leaning against it.

I would more worried about the total weight of the cylinder in a loft space, joists unlikely to be designed to take that weight. Horizontal cylinder might help to distribute the weight more, but could still be an issue.

Why would it topple any more readily than the hot water cylinder in the average airing cupboard? They just stand on boards / joists, in a cupboard usually crammed with clothes etc. I do accept that if one did topple, the walls might stop it falling far, but I've never heard of one toppling.

Assuming a 250 litre cylinder, it will weigh over 1/4 of a tonne when full. Placed on a suitable platform to spread the weight over the requisite number of joists, and preferably over a load bearing wall, it would take a pretty hefty shove to move it.

Unless your ceiling joists have been upgraded they are only rated to hold your ceiling up not support a 320 kg cylinder

I've just had my Boiler and and an Unvented 250litre cylinder put in the loft.

I need up with a structural engineers report recommending a pretty hefty platform made up to support it. No steelwork needed but 2 lots of triple bolted together 8x2 6 metres long across the width of the house with a central load bearing wall.
