So much for no more boilers!

This was new build (very well insulated) and underfloor piping. I don't know what was planned for DHW.

[The Natural Philosopher]

DHW is generally, in all but a small flat, fairly insignificant compared with space heating.

Immersion heater suffices

You mean he should have installed a tiny nuke to provide energy for his house?

[Tim Streater]

If they're connected to the mains, they're already using reliable nuclear volts and gas to backup their own and other unreliable systems. So what was your point again?

[Vir Campestris]

When I had my new mancave built I allocated 2m square to hold the oil tank. It's in its own fireproofed room. It confuses all the delivery drivers no end!

Keeping it in the dark I hope will help tank life, and it must be a lot harder to steal from.
