Central heating while away - maybe Builder can answer?

[abstibus]

If I go away over Christmas and New Year, what temperature should I set my CH at?
Do I need to leave all the radiators I use on?
I live in a three floor stone built Victorian town house.
Many thanks, and apologies if such a question has already been answered.

Iwould think 68 is ample and if you have therrmo xalves fitted turn em down a notch except where there is water ie bathroom and kitchen cus you don't want a freeze up in the old pipes

We have a tall centre terrace Victorian House, and we usually leave ours on 24 hours, with the thermostat set at 15 degrees if we are away (it only runs at about 18-20 degrees anyway when we are here). That means that if it gets really chilly, the heating will click on automatically. We never turn off any of our radiators.

We usually leave ours on 16 when we are away. Just to prevent any burst pipes

Hi annemollie ......... can only repeat what the others have already said. There is a frost setting on TRVs (thermo rad valves). It's a little snowflake symbol. That does leave the house rather too cold though. Not at all good for the fabric of the building in midwinter.

If you have a roomstat, 15 sounds right. If you don't have one, turn the TRVs down to say, 2
If you have neither of these (very unlikely) turn the boiler temp control down to around halfway.

Thank you all very much for your advice.
