Vitola's Smoking Den - or MLW Summerhouse.....

Looking good. I've been looking at log cabins myself, and so would be interested to know which company you went with in the end.

Keep an eye on the DIY superstores, I got mine from Homebase when they had a 20% off sale

Progressing well. Looking really good.

Great post.....very educational
I look forward to seeing it done.
For the BOTLs that use extract fans, do you use also supply fans? And if yes do you turn the supply fans on in winter?

Yes and yes

Yes and yes

What do you to heat the supply air during winter?

I obviously misunderstood your query. I use two small fans internally to circulate the air to the extractor but I don't bring in air from the outside.

Thank you....I was wondering if anyone use fresh supply air

The air that's taken out needs to be replaced somehow. If it's not by the same amount, the extraction rate will suffer. In industrial situations, this is fine by a lossnay heat exchanger, the air going out heats the air coming in. It would be hard to hear exchange in such a small space, so either have a supply duct that you can open it close or crack open a window to replace the air that is being sucked out.

That would of course be assuming that the structure is airtight in the first place and most of these cabins aren't.

A bog standard 6" fan will extract about 225 m3 per hour. Don't think the leaks in a shed would equal that!! Unless it was cold and damp all the time... 3.75m3 per min is a lot of air

Well I haven't suffocated yet!

No need for an air supply, although putting a vent in would be good anyway to allow the structure to breath properly anyway. I dont use internal fans to direct air to the extractor fan myself, a sufficiently sized fan should move enough air by itself, 4" bathroom fans are not powerful enough however.

I find my summerhouse holds its heat really well, a little electric fire is perfect. I insulated mine fully, but roof and floor minimum if you want it to be comfortable all year round.
[MENTION=13478960]Vitola[/MENTION] build looks very professional as well, you can see good preparation is the key to success

Cheers [MENTION=13452540]Shaun[/MENTION] as you say it?s all in the planning it does make the execution so much easier - appreciated!

Looking good! I wasn?t expecting to see such progress already. Well done and I?m excited to see the rest of this journey!!

I think that those figures are theoretical rates and would never be achieved in the real world. That said, a vent in the wall opposite the location of the extractor will improve extraction rates but in winter you may well notice a drop in temperature.
