Heating cost comparison

Mpmitch82

Hi,
I know there are plenty of posts on this subject & I've had a look at a few but can find exactly the answers I'm looking for.
I recently renovated a cottage & installed a solid fuel stove with s back burner that heats the radiators & hot water.
I didn't install an oil/gas boiler for a number of reasons, cost being one of the main one.
Also, most of the year I have a readily available supply of timber which costs me little or nothing.
However, at the moment I don't have any timber so I am burning peat briquettes regularly.
So my question is this;
How much does it cost to run to run a 2KW heater for approx 8 hours per day?
I am burning approx one to one & a half bales of briquettes a day at a cost of €4.50 per bale.
I get the feeling It would be cheaper to heat the house using the electric heater?
I'd appreciate any help. Thank you.

If 1kw costs around 0.18cent,then 2kw* 8hours x 0.18=2.88eur. 30 days respectively will be 86eur. It depends on what you pay per unit, check your bills.
Also, if a heater has a timer,it can be set to turn on and off so you can probably bring it down to 6 hours of actual running which will be 2.16 per day and 64eur per month respectively.

You are burning 1.5 bales of briquettes/day which results in a stove input of 1.5*67, 100.5 Kwh, the stove output @ 75% efficiency will be 100.5*0.75, 75 kwh to house & hot water heating. Useful cost/Kwh is 4.5*1.5*100/75, 9.0 C/Kwh.
If you are to produce this same amount of heat electrically ie electric heater + electric immersion, it will cost 75*18/100, €13.5/day as against 75*9/100, €6.75 for your stove.

I really don't know what a 2 Kw heater will do in the above context

Are you sure 16kWh of heat energy per day would provide you with reasonable comfort? I'm skeptical.

If you have open plan test it with your oven:) It probably has 2kW coil.

1kWh of heat will roughly cost you in euros:
-electricity @100% efficiency 0.16
-briquettes @50% 0.13
-coal @50% 0.12
-oil @80% 0.10
-gas @80% 0.08
-heat pump @300% 0.05

If 16 Kwh/day is/will be adequate then his whole house must feel like that oven with the existing 75 Kwh/day from the stove?.

When Mpmitch asked about running 2kW radiator for 8h I presumed he thinks it would be enough to heat his house.

He could test it by running his 2kW oven with open door which would be about equivalent of running electric radiator of same power. Right?

Hi,
Thanks for that.
It's a small cottage & I dryline insulated the walls
& ceilings when I renovated.
The one 2KW heater is more than sufficient to have the kitchen/living area & 1 of the bedrooms at a comfortable temperature. Well it is for the moment, I accept it might not be enough when the depths of winter hit..

Any yes, the house is like a sauna when the stove is on for any extended period of time.
Once the house is up to temperature I close it off, however over the course of a day it can still easily go through a bale of briquettes.

That's a very comfortable house alright but don't forget you will have to budget for your hot water needs as well now.
