How best to lag cold water tank?

[yjones]

Hi

Ive got some exposed pipe going into the tank.




Theres a very old rectangular lag jacket on the tank.

At the moment Ive put some old carpet on there too, for good measure. Hardly ideal!

What will I need to do a proper job of it? Some insulated duct for a pipe and another jacket? Will that suffice?

Thanks

Yes, foam pipe insulation and a proprietary cistern jacket, although you don't need to lag the one which goes up and over into the lid of the cistern.

Underneath should have no loft insulation.

Thanks. So dont bother lagging that pipe thats currently exposed at the top? Is that because lagging is only important for where wate is sat in the pipe? (just trying to understand). In which case that vertical pipe doesnt need the lagging that it has, but this pipe does?

(sorry, this is all new to me!)

That's correct, and if water does come out of that pipe then it tends to be hot.

Although it certainly won't do any harm to lag it while you are doing the other bits.
