New Horizontal cylinder in loft. Joist Reinforcement?

[GreenPickle17]

We are putting a 210ltr horizontal unvented cylinder in the loft. Do we have to reinforce the 1930's joists to take the 350kg weight?

Can't have a vertical as having a loft conversion and no room.
Won't fit in the kitchen.


Thanks in advance

210 litres = 210 kg

wheres the other 140 kg coming from.

and imho you will need to re inforce joists

Reinforce the joists and lay a sheet of marine plywood as a base.

Loftjoists can be a lot less strong than floor joists as they only have to hold the ceiling. Best to reinforce them, if possible by making them higher (40% higher is 100% stronger) and make sure the connection to the wall is still solid.

Cylinder weight will add 50-65kg depending on the make.

OP, I hope you wont be too disappointed with your Horizontal cylinders performance.

Surely if you're getting a loft conversion you'll need to reinforce the joists anyway.

The cylinder is going under the eaves where they haven't reinforced. The joists are between the outside wall and a load bearing inside one.

I will ask the builders.

The horizontal cylinder CAN'T be as bad as the worst combi in the world we are getting rid of!!! It all depends on your bench mark and ours is fairly low.

Thanks for your advice!

That will certainly help

Go on then, tell us it is an ideal that is being skipped.
