Energy shortfall preps

[Highlander]

We have had this fire in now for a couple of months, it is a wrap around boiler muti-fuel burner, it runs the central heating and heats the water,.. but it is also linked to the oil central heating, [ while we can still afford it ],... so if the fire gets too low,.. say over night then the oil kicks in, at the moment I think we have it just right as the oil kicks in for just 1 hour just before we get up in the morning
