Cheap heating....?

[diamond lil]

Following this with interest. Husband has bought a diesel heater for his new shed, due to be delivered early next year. He hadn't ever heard of them but his pal down the road has them in his shed and motorhome and is now getting one set up for his house. Only thing is he is unsure of is how to stop the exhaust heat setting fire to the shed where it passes through the shed wall to the outside. And YA or JM he is asking if the air filter should be outside as well?

What sort did he get lil? The free standing jobbie or the kit version?

You can strip the free standing one down easy enough I'd still replace the fuel line anyway

Both the combustion intake and exhaust should be outside they can cough and fart exhaust smoke out the air inlet if they dont start properly or flood ...

I'd mount using a turret plate this keeps the exhaust well clear of the shed

Andy it's this one but with only one outlet hole not four. It says 8KW and he got it from a guy here, cost £100.

Precisely! The fitness is THE issue here now. Fortunately,I have enough cut for this Winter and next.

You already know; but worth reiterating:

Work smarter not harder,

If you can get it delivered already cut to length great,

if not have it dropped as close to your stacking point as possible.

with my heart condition it is worth more for me to have someone fell, cut, split and dry, and deliver it to me in large rubble sacks then it is for the price it could cost me.

All I have to do is stack it into the wood shed, and carry indoors to burn.

Lack of work IS the way ,for sure P.

I used to use a diesel heater when I lived on a boat. Very effective. Some of the 8kw units are rebadged 5kw units, though. You'll get a fixed amount of heat from a fixed amount of fuel. A bigger unit/chamber doesn't mean you'll get more heat, you'd need more fuel delivered to the mix to get more heat out. If the pump is a 0.22ml version, its theoretical maximum is about 5kw, if I recall the maths correctly (been a while since I worked it out). Some of the models do hot water, too, or you can put a heat exchanger round the exhaust and save some of the waste heat that way. I sometimes found that running the unit in high altitude mode saved on fuel while still giving enough heat. As I understand it, it increases the air (or lowered the fuel) in the mix, meaning a slightly lower heat output, but a more complete burn (I think).

I never ran it on anything other than white diesel. Boat yards are known sometimes for having one big delivery of fuel that sits in a tank and gets water in it, causing diesel bug. I had to have the engine repaired once because of boatyard fuel. The turnover in a petrol station solves the problem, it doesn't sit around getting wet.

I have one now, waiting to be set up. They're great little units, and a lot cheaper than an Eberspacher or Mikuni. They're basically a knockoff of the British versions, which are very expensive and require yearly maintenance and servicing. I'd have a go at taking a £100 unit apart myself, but no chance I'd fiddle with something costing over a grand.
