A bit like "terror" or "transistor" or "teleporter" then.

It'd make sense wouldn't it...


That's why they are!
Oh you don't shop where I do.

There are two sorts of tea urn.
Unpowered - double skinned
Powered - Double skin with insulation between the two layers.

Try your local government surplus store for an ex-forces urn.

I am doing a project for my maths degree on whether it is economically viable to run an insulated tea urn.

I agree with the theory of insulation (being a bit of an eco buff) but the question remains

When I search for hot water urns they are generally uninsulated. I suppose this is down to the time the water is kept warm for - perhaps 2-3hrs max

I compare mainly with the hot water cylinders in the house being lagged (a legal requirement) where someone may have the water constantly at temperature.

I am looking into whether it is viable, given the higher initial cost, to buy and run a tea urn that is insulated. My main problems are finding costs to buy the urns - all the priced ones (amazon.co.uk) are not insulated. My fear is that the extra price tag is enough to put off most potential purchasers

They'd also have to be larger or smaller inside, and heavier.

agreed. Plus the outer skin would have to be coated - which would add to the cost more.
trying to get cost differences is a nightmare

However, you're on Downsizer, where the actual answer to the problem would be that Sally/Mochyn would knit you a giant cover, and Richard would set up a fully grid independent solar system to run it, and harvest the excess heat back into your living room.

And everyone else would make cake to serve with the tea. And MJ would organise it all.
