Heating on low all day??

damo80

Hi looking for people's opinions on best way to heat house with oil burner. 2 zones-zone 1 is bedrooms/bathrooms and zone 2 is kitchen, dining, loving room. Is it better to have boiler on low temp and thermo set to 20c all day or turn on for timed periods?

It depends on loads of things. Your house for one.


Answer will be different for each home.


Mine is timed and for me its optimised for that

I'd say you could turn down the temperature in the loving room for a start :-)

its a new build with no underfloor heating, occupied all day. just curious as i burnt through over 500 litres of oil in 2 months working off the thermostats in living room and main bedroom. timed to come on at 0630 and off again at 2300

You're going to typically use 2-3 litres per hour while the burner is actively firing.

Without stats the system will probably use 2-3 litres of oil for the first hour from cold and then about 1 litre of oil for every hour thereafter.

So for it providing heat for 16.5 hours, you could expect to use anything up to 25L of oil a day, at that rate you'd have used 500L in about 20 days.

With the stats though, they'll likely stop calling for heat after a few hours of the heating being on meaning the burner may only be firing for a couple of minutes per hour as the stats kick in/out to maintain temperature.

Still - 16.5 hours of active heating and you've used 500L of oil in 60 days is just over 8L of oil per day which is not entirely unreasonable.

My own is on for an hour before we get up, an hour before we're due to come home and then 45 mins in the evening to give a final boost for the few hours before we go to bed.

We use about 4-5L of oil per day for 2.45 hours of a a heating window, so 8L of oil for 16.5 hours of a heating window for you is not entirely unreasonable in comparison.

Thanks so much for that KildareP. Guess I'll have to turn down the stats from 19-20c.

Get a smart thermostat and Set the thermostat to the temperature you want.

First thing to remember is that your newbuild is still drying out so more energy (oil) required to maintain a certain temperature. This drying out process can take up to 18 months depending.

I did not know that to be honest cheers.
