Construction costs are currently skyrocketing

Hello,

House with wood gasifier, approx. 40 RM consumption per year,

a dumb question, what kind of house is that? Depending on the type of wood, that's 60,000-80,000 kWh of calorific value! Is it really that inefficient or is it an uninsulated barn?!?

Obtaining 40 RM of wood every year, chopping it up and carrying it around is quite a statement. Apart from the fact that it needs to dry for 3 years, so you need space for 3 stacks of 40 RM each? How do you manage that?

Best regards,

Andreas

Morning,

a stupid question, what kind of house is that? Depending on the type of wood, that's 60,000-80,000 kWh of calorific value! Is it really that inefficient or is it an uninsulated barn?!?

Getting 40 RM of wood every year, chopping it up and hauling it around is quite something. Besides the fact that you have to dry it for 3 years, so you need space for 3 stacks of 40 RM each? How do you manage that?

It's almost identical for us. Old farmhouse of my parents, if not all rooms are heated, 35 RM are gone. Then three more households and some grill wood, and you're at 100 RM per year.
Space isn't the issue, it's divided into a few stacks out back on the field.
If you're dealing with such quantities, you don't use a 750kg hardware store trailer anymore. If the wood isn't conveniently positioned for transport, I rent a long wood transporter, which costs 250€ and fits a good 40 RM. If it makes two trips, most of it is already home.
Alternatively with the tipper, two people 5 RM in the morning and afternoon, makes 10 RM cut, split, and stacked behind the house or on the field in 33 cm pieces on a Saturday. Cover it with a tarp, done.

... Oh wow, I suspected it, but then let's also correct the half-knowledge...

I'll take that as fitting for a generalization. But for your information: This is not "half-knowledge" but lived reality within our family circle ;)

We now have our own stove for the first year. So far, we have more or less gotten the wood for free. Large poplar pieces from an acquaintance and a 20m fir tree that was too close to the house. Not easy wood for beginners. I’m looking forward to the first meters that have a normal diameter next month we’re going into the bend. We don’t have to pay for that either. By the way, I also “tried” splitting, but honestly… what a load of crap. I find it much more dangerous than handling the chainsaw.

Hello,

Old farmhouse of the parents, if not all rooms are heated, 35 RM are lost.

Wow, that’s about 5-6 times the heating energy demand of our house! And we have 180 sqm plus basement completely heated.... Maybe the plans to make energy renovation of old buildings mandatory aren’t so bad after all...

That is really an extreme wood consumption.
