Background
I installed a Honeywell CM927 in the summer (following advice from this forum!) and am very happy with its performance.
As my house is old and drafty (despite my best efforts to improve it!) and I have young children I want to set the thermostat at around 15deg and leave it on all night.
My System
Thermostat: Honeywell CM927
Programmer: Potterton EP2001
Boiler: Potterton Profile
Plumbing: Gravity Hot Water system (?)
The Problem
I left the heating on all last night, but the boiler and pump kept firing up to keep the hot water to temperature (60deg).
This is noisy and seems like a waste of energy as I won't need hot water from 9pm to 7am.
My programmer allows the hot water to be on without the central heating, but not the central heating without the hot water (I assume it is a gravity system).
The Solution?
Can I just replace my programmer with a more advanced one that can be set to 'ignore' the cylinder stat between certain times?
I understand that I can't have the central heating on without the hot water, I just don't want the whole system firing up just for the hot water during the night.
Any help would be much appreciated.
