Water cylinder and F+E tank positioning/DIY Heatbank

[matt2005]

Hi,

I'm in the process of renovating a house, The house has no hot water, so I'm going the thermal store/heat bank route as we currently don't have gas (waiting for LPG to be installed) and have a Rayburn which I'd like to get connected to the cylinder once more of the house is done.
In the meantime I'm going to use a immersion heater to heat water in the cylinder and heat the DHW via a PHE, thus doing away with cold water tank in the loft.

How high does the F+E tank need to be in relation to the water cylinder?
The water cylinder and F+E tank will be both in the loft next to each other.

Thanks
Matt

The Feed and expansion tank relates to the heating circuit not your hot water cylinder. I think you are getting confused.

ps what is a PHE?

Ideally it should be 1 metre from the top of the cylinder to the bottom of the cwsc. Not always possible but the more height the better the flowrate.

Here is a diagram of what I'm doing.

The image originally came from uk.diy wiki I edited it to only show what im I'm doing.

A PHE is a Plate Heat Exchanger.
