How much will i use? - Oil fired Combi

sbroooks

Hi

I only want to use it for running baths, one a week (at least)

It's a Worcester Heatslave 12/14
(Efficiency Band C)

I've looked everywhere and all i can find is people using it for heating and water.


I'm unemployed, just moved to Wales.
I'm going to fill it with 100 litres and it has to last me through winter.

Just for baths (hot) and a facewash (lukewarm) in the morning.

Thank you so much for helping, ive no idea where else to ask about this

I intend on moving in April, i had little choice about this tenancy, it was a blind move.
It costs a quid to heat up enough water for a bath with electricity, (elsewhere)
If oil is going to cost me 10 times more (from browsing it seems it shall) then i'll know not to bother with it, I'll have to go Victorian.

A 12/14 heatslave uses a .50 nozzle size which means the burner uses .5 of a us gallon of oil every hour it is firing. For hot water the boiler 1st has to get its thermal store up to temp then the burner fires whilst the taps running, a 12/14 is only 14kw so takes a while to heat the store from flat cold, I guess around 15 mins. So as a rough guide say 15 mins running will use 0.125 of a us gallon which I've just converted online into litres and got .5 of a litre. This is all theoretical though and not real world

so, worst case scenario im looking at a litre of oil per bath (£1)

which is acceptable

Thank you

Morning facewash? Come on! Cold water wakes you up!

How far is the local swimming pool? If you're bathing once a week, why not pay to go swimming (great excercise!), take your shampoo, and use the showers afterwards?
