Water cylinder overflow/run-off problem

[potato80]

Hi all

Our water cylinder (pictured) seems to be on it's last legs; it's just tripped the electrics and I'm not sure if it's still working or not.

I had a plumber in a few weeks ago who noted a replacement cylinder would be a challenge because of its position in the middle of the house away from any external walls, meaning the overflow/run-off (?) pipe would be difficult to install.

If aesthetics weren't an issue, is it possible to run such a pipe along the route highlighted in red (i.e. over the doorway and outside). I can't do it via the route highlighted in blue because it's too far.

I was hoping there's a solution for cylinders located away from external walls

Any help/thoughts much appreciated!

They get put in basements, there are "solutions" ranging from a bucket with a sump pump in it, to a £1000 special high temp pump thing. PH-5L-HW TPV is one of those.

Simple answer is contact a few manufacturers. It's up to them. Local Building Control theoretically have a say but yours might be clueless.

A standard solution is to use a thermal store, instead. That looks much the same, it's a cylinder of water heated up by the boiler. The mains water runs in a pipe through it. so you get mains hot water, and no discharge pipes, or special certification to fit/maintain them.
The tank part used to corrode rapidly, but today's inhibitors should cope with that. Gledhill is one make. Some people hate them, others love them. I think they're ok, and the solution I'd look at in your case.

Thanks so much Thermal store sounds like a plan
