insulating tanks

hey

what's best for the side of water tanks-foam board or fibreglass?

and what's best for the lid?

and should you fit a lid if you're using an infra red lamp over the tank?

thanks

Fibreglass is fine, you can just tie it to the tank.

As for the lid, its part of the new regs that it has to be fitted.

ya i knoow-not too many lids round here


just wondering is the frost protection better with the lid off or on

and if there's a lid-how to position the infra reds

Its unlikely the water in the tank will freeze soild anyway, considering the volume of water in it. The things to protect are the pipes and the ambient air around them to stop them freezing. In the same way that the frost watch heater are operating, it heats the air in the attic. I'd position it sitting over the bulk of the pipework if it were me.

Plumbing regs, just like electrical ones....... Great idea, but makes current installations out of date very quickly.

You can buy a lagging jacket for water tanks along with the lids. The reason why they were never fitted is because the lid was as expensive as the tank. That sounds daft but its true. Your not suppose to use fibreglass on the side of tanks because it gets wet from condensation but the builders always have.

If it were me i would simply buy a lagging jacket and lid. Its easier to for and is regulations.
