[Closed] Heating the mancave & insulation.

first thought is I hate handling rockwool

second is it seems wrong to spend money on electricity heating a man cave. I am planning a wood burner as I keep seeing them on offer at Costco: http://www.costco.co.uk/view/product/uk_catalog/cos_2,cos_2.8,cos_2.8.1/140525?utm_source=emailFY14P2W4a&utm_medium=Feat-8&utm_term=140525&utm_campaign=emailFY14P2W4a

That one looks a bit overkill for a mancave ^^^

I lined mine using Celotex on floor, walls and ceiling:

I've just bought a dehumidifier which is running 24/7 on its humidistat. Not sure what I'm going to do heat wise, will probably have an oil filled electric radiator on a timer for when it gets really cold. Right now I just want to make sure it doesn't get too musty.

Its really worth remembering that drafts are worth addressing every bit as much as insulation.

All that work and you still need to run a dehumidifier ? What went wrong ?

Its worth remembering its a shed at the end of the day.

I don't know that I do, but given it's unheated, I'd rather make sure the humidity is kept low, as once you get mould it's a pain to get rid of.

Only shed i get mould in has a porous roof.

not much point in adding £££ insulation unless you are going to heat it - electric fan heater probably best to quickly warm up areas like that

I use a gas bombola- but if your going to plug up all vents your going to not want to use a gas appliance.

Equally with no ventlation your going to get no air movement. Stagnant air =

must be a grand on insulation there Footflaps?

Remember now all that celotex in yours footflaps. Depends on costings again I guess. Good point re humidifier, mine needs to dry out a tad so may try and borrow one for a while.

I would like to put a stove in there at some point but as I'm going to run electric up there soon(ish) I thought some sort of electric heater that's programmable would be ideal to put on for an hour or two here and there?

Agree that first stove is mahoosive but the machinemart one might be better size wise but still over 6KWh!!

I'll check out the 2nd hand insulation site think they're on ebay as well?

Frontier stove?

Oh yes, remember those from a previous thread. They look good but dont they take up some room with the legs?

This one ...

Is there any real need to heat it? I've never bothered to heat a workshop, year round I work with the doors open.

Its not that big either.

I have a 25ft by 10ft bt 8 ft high garage. Ive celotexed the roof but besides that its just singleskin block. 20minutes with the bombola has it heated for the night.

A woodburner will just be getting up to speed when youll be finished what yer doing.

Did anyone see the "Great big energy saving challenge" on bbc2, just finishing now. They had a solar air heater, which looked amazing! Lines of drinks cans, glued together and sprayed black, in a glass fronted frame and then feeding through an insulated ducting into the house, was pumping out warm air into the house at 30 degrees for free. There must be a catch though. Although without sun or bright daylight, it must be useless. So nights would be cold

Although without sun or bright daylight, it must be useless

I ran a solar oven workshop once. Quite good fun, there are hundreds of designs each aimed at a particular culture or economy (whether a certain population makes or buys stuff and whether goods are manufactured locally at a cottage industry level). Each design also takes into account when in the day people eat and where the sun is at that time of day at the latitude. Some are are satellite dish fresnels that point up for cooking in the middle of the day at the equator some are like clamshells for cooking breakfast and supper when the sun is low. They can be quite beautiful.

They require less sun than you'd imagine - our workshop was in the context of humanitarian aid and survival so the goal was to be able to pasteurise water - get it to 70degs. With a tinfoil wrapped cardboard box, a cooking pot painted black and clear polythene bag we were able to get the water in the pan up to 70 degrees in about a 20 minutes on a lincolnshire october afternoon

I'm saying nothing!

Any links for a bombola type heater?

About £2.5k if I recall, something like 60 8x4 sheets.

That's what I use when I'm in there and it only needs a 10 min blast to warm it up. It's only the last few weeks I've had to think about this as it's spent the year so far with all the Veluxes open on their latch about 1".

its something like that i have .

got it FOC

made sure the garage has plenty ventalation

Double bubble foil insulation has my vote. So much warmth for 1 tiny layer of insulation. So easy to just Staple into position too.

Double bubble foil insulation has my vote.

That's just asking for trouble.

I'll get my coat.

Can you elaborate?

Was tempted by one of these but thought it might look a bit lost in my 'shed'

I have one of these "super ser" heaters good job for the garage and easy enough run when kept on the lower setting.

[i]About £2.5k if I recall, something like 60 8x4 sheets.[/i]

Seriously?

68 sheets in total. Can't remember the actual cost, but at, say, £35/sheet it would be £2380

This was the first batch, 100mm on walls & floor, 75mm in between rafters

Smaller bords I know but used for price comparison: http://www.toolstation.com/shop/Construction+Materials/Insulation/Celotex+Insulation+Board+50+x+1200+x+450mm/d210/sd2738/p10635

Works out at about £1800 for just the boards in 50mm + fittings and tape etc. Scary how it mounts up!

I am planning on building my whole shed for less than that. We'll see how that plan goes though...gulp! I will be a business expense though.

Just dug out the prices:

10 sheets Celotex GA4000 75mm (Insulation express do this at £23.76 ex VAT)
28 sheets Celotex GA4000 100mm (Insulation express do this at £30.24 ex VAT )
30 sheets Celotex PL4000 50mm+12.5mm P/B (your web price is Price ex VAT: £33.98)
