The problem: Our new home has a "frankenstein" gas water and heating set up which uses a 'System Boiler' and an immersion heater.
Simple (and possibly stupid) question; As my heating is not on a combi boiler (the boiler looks like our old combi, but only one "half" works... there is a thermostat inside the house and an old immersion heater for domestic hot water), will my Nest thermostat still do the job?#
We've taken it with us from the old house and it isn't installed yet. I'm hoping just a simple switch from the old 1990s thermostat with the Nest heatlink and then the Nest thermostat is all that is needed to upgrade -and that the type of heating system is immaterial.
The current thermostat is inside a cupboard (WTF!?) so i'm just looking for flexibility with, firstly, relocating it to a a sensible place (probably living room, possibly hallway) and ultimately have more control/presets and use routines.
The sticking point, I'm worried, might be our physical heating set-up.
Am I right to be worried we can't use our Nest thermostat?

So are you saying the system boiler is for heating, and immersion heater is for hot water?
Do you have any form of controller for CH/DHW?
Your system seems very old/non maintained/non upgraded...
Possibly a system boiler with a non working diverter valve?
What make and model is the boiler?
What's going on?
