Oil heating for every day bath?

Soniboy84

Hi,
yesterday in my bath I was wondering about something...
We've been just moving in to a house with oil heating, bought 250L oil to "test" how long it lasts.

We heat the house one hour in the morning and and other hour at night. 1 hour heating produces enough water for a bath for me(tub is almost full), which is good, because we don't have to turn on the electric heater, and I love baths on cold nights.

My question is: what would be the effect of having bath every day?

Does it heat up the water tank only if it's cold, and switches off when it reaches desired temperature? Or it uses the same heating no matter tank is cold or not? It's very well isolated by the way, I heat up the water at night, and in the morning it's still hot!
I think I certainly would pay more, but is it noticable amount? Burner looks also quite new, and maintaned.

Thanks for answers!

Your questions are not dependant on the fuel used, but the timer/control system installed.

In answer to your main question - emptying the hot water cylinder everyday for an overfilled bath would use more fuel (gas/electric/oil) when compared with, say, having a shower instead.

If your system is a usual one then the cylinder post-bath, now full of cold water, would call for heat during the hours the timer is switch on for hot water and thus the boiler will fire.
