insulation for loft water tanks?

tstodart

Hi all,

I am trying to insulate the hot water pipework in our house, where accessible, and recently investigated the loft.

The loft is insulated, but the insulation has not been put under the cold water and feed and expansion tank, which I think it OK.

However, neither the cold water tank or feed and expansion tank are insulated.

I am going to insulate the cold water tank, just to prevent freezing.

Is there a benefit to insulate the feed and expansion tank in terms of energy saving or other benefits? If so, is it OK to cover it (at the moment it does not have a cover at all)?

Thanks in advance for any advice!

Hi

New cold water tanks and the f&e tank will come with a byelaw 30 kit. This makes them almost completely sealed to prevent dirt /insects getting in the water.
A huge number of tanks have nothing ,or all kinds of bodged up lids/ lagging.


Basically the lagging around the tanks is fibreglass in a bin liner.Maybe make somthing up or get the fibreglass loft insulation thats sealed up in plastic or foil. The most important bit is the pipework.
If you need to fit a cover on a tank use something that won't rot.
There is no energy saving to be made ,only money saving if you can prevent a freeze up.
