Heating/Plumbing question

[Bitfik]

Are there any heat/plumbing engineers here?
I'm going on holiday over the Christmas period and I wondered what was the best setting for my heating in case it turns cold and pipes freeze. I have a high efficiency boiler and will be away for around 10 days.
My current thinking is to turn it to lowest setting and leave it to run 24/7.

Any advice would be welcome,
Cheers.

I would usually leave the room stats at 15C  and have a neighbour check regularly that all is ok. 
All is fine until the power fails

Set ur boiler to frost mode & turn all ur room trv's down 2 the minimum, boiler will fire up every so often to prevent any freezing issues if it's a modern set up like you say. Defo would not say leave it on permenantly.

Doesn't your thermostat/timer have a frost protection setting?

My neighbour regularly goes to NZ for a month in January. Shortly after she'd left a couple of years ago I noticed that her boiler wasn't blowing clouds of condensation out across to my back door as it usually does.
Rang her son and told him his mum's boiler wasn't running and a cold spell was forecast. Instead of coming to check the problem he rang her and reported back that she definitely remembered setting the thermostat to 15ºC. A few freezing days later the house was obviously very wet… phoned the lad again. This time he came over… discovered his mum had indeed set the 'stat 15º, but had absent-mindedly switched the boiler off too.
It was 8 months before she could move back in.
If you've someone you can trust to check the place if there's a cold snap, I'd give them a spare key.

Cheers guys. Frost mode seems to be they way to go.

I get asked this all the time....my answer... don't be a tight arse.. leave the room stat at 18 and let you heating come on at its normal times... the gas use is less than the heart ache of coming home to find you rads have ballooned and thrown themselves off the walls and you home has a sprinkler system that you didn't know you had.

ive seen all this happen when we have a cold spell and people have taken mates advice.... after 31years of being a heating engineer, ive seen a lot....and will proberbley see a few more sights before  I pop off...
