hot water tank insulation

[faffer]

I have an old (my flat was built in the '80s), rectangular boiler (the shape of the box it's housed in is rectangular, I assume the actual boiler inside is also rectangular but perhaps not) which I recently moved out of it's airing cupboard and up into my loft. I'm still getting hot water ok but I imagine it's taking a lot longer to heat and taking a lot more energy, also by the end of the day on cold days it's noticeably cooling down.

I assume that there is insulation already within the casing but are there *rectangular* insulation jackets available for hot water tanks? I found some for cold water but not hot. Any recommendations for how I can top-up it's insulation?

Thanks

Are you talking about a tank full of water with an immersion heater in it or an actual gas fired boiler?

If it is a tank, I would suggest boxing it in with Kingspan insulation - it's about4 inches thick and you can cut it with a saw.

Thanks - I am talking about an immersion heater. I'll have a crack with the Kingspan insulation.

Thanks again,

Stick it together with "no nails" or similar (at the edges only - dont get any on the tank)

Thanks again, that would've been my next question!
