How Much Wood do you Burn in a Week of cold Weather?

[Billhook]

Just been working out our consumption.  25KW boiler stove with 15 radiators.  Wife does not like the cold so we are using a 2 cu metre or 72 cu ft box of loose stacked dry Ash which I think would weigh about 750 kg or 3/4 ton a week.  Stove is on all day and most of the night.

That seems excessive.

Is your house insulated?

[Mick Dempsey]

I suppose it depends if we’re here all day or not.

Approx 1 barrow a day on average whatever that is.

about 1.2 cube every two weeks which  equates to about 15 cube over winter. i stopped splitting logs a couple of years ago and just cut 10 inch diameter (or less) cord into 12-16inch rings

Goodness me. I bet you are glad you heat your house with wood not gas!

 

 We have a 15kw boiler stove with 8 radiators, but usually only have it lit from about 3 or 4 in the afternoon until about eleven (though of course it stays warm to some extent until much later).  We are burning mainly three year air dried oak currently and get through about three quarters of a cubic metre per week.  Weight would be about 180kg.

If I was going through that much wood and the Wife was still cold, I would be checking for a pulse.

A lot less now than we used to. 

 

It's been averaging about 0c here for the last ten days (day and night average). We use the stove(10kw, in the kitchen, which is 35 square metres and open to the upstairs) to supplement a bit. I reckon we've maybe used a barrow a week so far.

 

The primary heating is geothermal and the other secondary heating is an air to air heat pump in the living room. Total power consumption is about 30 kWh a day at the moment. 

 

If our house here was as thermally inefficient as our last house in Devon, we'd be utterly f**ked

Whilst I don't know what your running boiler wise or your system, 25kw if it's running full power that's 5kg an hour (5kw per kg).

 

Guessing it's running a hot water cylinder aswell unless your radiators are 1.6kw a piece. Do you have a buffer tank with a thermal mixing valve on the radiator circuit?.

Maybe half a cube per week? One to two recycling boxes of logs per day.

 

(Two wood burners, at least one usually lit while I'm about, oil boiler and Ch)

 30kwh per day is huge! Was the Devon house even worse? We use about a 3rd of that, in a big, old, cold stone house in a dark Welsh valley
