Skotl's diesel heater garage install thread

[fizzy]

Diesel…. Not paraffin … Unless you either like replacing the pump or are going to add lubricant.

Mine has run for 5000 hours on kerosene with no problems at all. Where did you get that idea from?
Kerosene is cheaper and cleaner than diesel.

 

[fizzy]

Red diesel is easy enough to get. Ask any digger type person, some garages actually sell it

Nope idiot government are banning it

 

[fizzy]

I was under the impression that either fuel was suitable. Have I got hold of the wrong end of the metaphorical stick?

Kero is fine. 5000 hours on mine not bad going!

Marinas still sell red, not sure how much longer though.

As my boats heating is diesel it gets a discount

Boats will still be allowed.
Agriculture and forestry
Domestic use
Construction industry is foobarred

 

[bert]

Nice to hear boats are still allowed but the marina charges 1.41 A liter including the discount so not much better than standard.

I wonder what the rules will be on running engines on kero? Mix in a bit of cooking oil say 5% and you won't tell the difference.
Not clear on the HMRC website. They suggest the construction industry switch to it for site heating etc.
After all you are allowed to run generators on mains gas and that is untaxed.
I think we might see some Komatsus and Caterpillars running with gas bags on the roof like Jonesy's van

Having bought @skotl‘s other heater and now fitted it in my conservatory, I have a wee question. Is there any reason I cannot use a tumble drier insulated vent hose as my heat output hose.

The reason being, the heater is mounted quite high up to keep it next to the exhaust exit point in the conservatory, and I’d like to extend the heat ducting down to floor level, where it should be more effective.

All the output ducts I've seen have been the corrugated aluminium type. I think the output can get quite hot so would depend on what the tumble drier hose can cope with.

I've measured mine at 110C which seems a little hot for plastic

Those lengths of ducting supplied, with these heaters, will stretch to about twice the original length, I believe. That should at least direct the warm air downwards quite a way. Extending the duct will require an increased diameter such that the pressure drop is to specification (ha ha, not in any chinese instructions?).

The Eberspacher instructions provide any necessary details for designing ductwork to proper dimensions.

I wouldn't risk it. You will lose loads of heat unless it's in the same room anyway?
Mine is above my office roof in a freezing warehouse. I also have an insulated return sucking the air from the office so it is recirculating.

Having said that give it a try.
The housing of the heater is plastic anyway.
Might go all limp and floppy

 

[bert]

The pipework on my boat is aluminium and gets quite hot as it comes out of the heater.

 

[OJCar]

As said too hot for plastic drier hose. (it only goes up to about 80C )
I'm using this;

for extending the one in my garage.
(They are just along at Eyemouth).

This is the stuff I was looking at. Definately a step up from your usual flaccid tumble drier hose.

It’s just used to heat the conservatory to make it a bit more usable in cold weather, without having switch on electric heaters.

It’s not the exhaust pipe, that’s happily vented outside, but the heating vent pipe I want to extend. Being fairly short, is great for heating my head, but carp for cold feet.

Yes I understand that. My heater came with thin corrugated aluminium ducting for routing the hot air.
