Immersion heater

[Justtin]

hi,

What kind of set up is this? Are here two heaters? If so why are they not at the top and bottom of the tank?

There is only one immersion heater shown. The box above it is a thermostat to control the temperature when water is being heated by the boiler.

A please may have been nice, but yes mr stem is right one heater only I always thought should have been one further up for when hot water demand was low.Bob

What kind of set up is this?

Its a fairly bog standard indirect unvented cylinder with an immersion as back up.

You sure are 'trying'

I've seen a few where there is only an immersion fitted at the bottom. I guess the normal method of heating the water is by using the boiler and the single immersion is purely fitted as a back up.

Twin heaters are usually used when electricity is the only form of water heating, such that the bottom element is used to heat the whole tank during an 'off peak' tariff and the heater a bit higher up just heats the upper half of the cylinder as a top up if needed.
