Heating Hot Water / Central Heating

[DiamondGeezer]

We had an old timer (one with the little pins) to switch on/off hot water and central heating

We've always heated the water twice a day in the morning and evening but we just had the British Gas Hive system installed. The engineer says its best to leave the hot water on all day as it is more economical to replenish what is used rather than heating from start to finish.

We don't really need hot water during the day as we are out apart from weekends hence why we've always just heated twice a day rather than leaving it on all day

Any recommendations and also for central heating, is it best to leave it on low all day or just heat up from cold when needed

You only find out by testing IMHO. I you assume two consecutive weeks of similar weather and do your twice a day program for week one and 24/7 for week two then compare usage you'll have a reasonable idea.

Of course the weather may not be the same and your level of insulation will have an influence too.

That would only make sense if you had a totally uninsulated tank.

Tank is insulated

One of the Hive system's selling points is controlling your system via Internet and 'phone apps. Surely leaving it on 24/7 kinda defeats the point?

It's not on all day, the engineer set the hot water to be on from 6am - 10:30pm which he said is more economical rather than switch on / off twice a day for around an hour.

The system does give you better control of your heating, ie I've set mine up to come on later at the weekends when we don't need to go out so early in the morning.
