shed heating

[haynes66]

i cant remember if i've brought this up before, but any tips on best heating for a wooden workshop?  it's not too bad out there but my tools are a little damp sometimes

I would have thought anything that is gas will create damp as when gas burns does it not produce water as a by product?

That will then form condensation when the temp drops

Maybe a electric tube heater just to keep the place above freezing if is a small shed but these days everything that is gas or electric is money hungry

Even my garage that is part of the house with a bedroom on top gets cool but thankfully no condensation issues and if it does get colder I have a C/H rad plumbed in that I can turn on to keep the place comfortable

I've put a spare electric pipe heater of (I think) around 100w into my 20' by 10' cedar bike garage and so far this winter, although it is wetter than we can ever remember, it's held condensation at bay.

Without the heater on previous years, there have been real issues with damp in there.

a dehumidifier is a good idea but i also want a bit of warmth to work in there! my 62 year old joints dont work well in the cold

Portable air con unit can be used as a heater

   I use a cheap Chinese 5Kw diesel air heater, the same type as used in lorries. They are a indirect hot air heater so do not have the
   same condensation problems as heaters using a open flame. It is used pretty much daily through the winter and is now on its 5th
   winter and hasn't been any bother at all. If it failed now I would get another immediately. The only drawback to them is they are a
   little noisy. Certainly nothing like as noisy s a small space heater. Do not be conned by the 8kw claims they simply do not do it and
   they are exactly the same as the 5kw units. Running costs when on max 5kw 0.5 ltr per hr, red diesel approx 85p per litre.
 
   This type.

It might not be the cold but the damp, I find the dehumidifier also gives out some warm air.

I'm with Oddjob, I have run a RubyDry dehumidifier for the previous five years in a 18ft x 18ft pre-cast concrete garage on its lowest setting, approx 150w from when the temp drops below 4c (although I've lined the garage with 50mm kingspan on all the walls and floor). I work in the garage a few times a week.  The air is dry and actually warm to the extent there is no chill. Yes, its expensive to run at approx 4-5p/hour (likely to be 7-8p now the energy prices have gone through the roof!) but this is nothing in comparison to watching the bikes suffer with damp and condensation and the cost and time to put them right. I used to switch an electric heater on before I had the dehumidifier but it created so much condensation I stopped using it.

Why not let the dog/s sleep there overnight, body heat and guard in one package?

In the winter I run my de-humidifier during economy 7 hours only on a timer - even then last years electric bills during that period were pretty hefty my current rate is 10.2p/kwh.

If I do any work in my garage now that it's getting pretty cold I run my twin 500W lamps as they are good for directing the light & heat onto the area I am working in - cost is not a biggie as I only work for a maximum of 2 hours so that's at 16.20 p/kwh.

  De-Humidifers in cold rooms. Try doing a simple google search, refrig ones are not worth running,

No had one in loft once due to damp on felt in north side eaves

Yes just froze  up

Mine is a dessicant type I believe the Ruby Dry is the same type they do put some heat out as well.  It never fails to produce the condensate from operating at all winter temperatures.

Wrong kit, the pro sets have frost protect sensor/stat and defrost heaters...

[allankelly1]

To be honest better ventilation in the roof by adding small gaps in the felt rather than having one of the “modern sealed” lofts solved everything

As all warm moisture in modern houses will end up in the loft and without any flow of air will condensate on a very cold roof felt

If fact my mate had same problem and did same thing

That's correct Ted. Mine runs fine in zero and lower temperatures. The heat is produced by a small heating element inside the Ruby Dry to dry the condensate from the spinning disc. I understand the water collected in the tank is deironised and good for the ironing whatever that is🤔
