Indeed, I've had a close look at my van, and it seems that apart from the hole in the floor for the rollers, it's incredibly well closed off. The Berlingo had vents inside the back of the chassis, I didn't have that much of a problem with the old van. Oh well, small thing, roof spinner will sort it out.

I have the Fogwash vented through the roof and you are right it isn't a sealed unit. The metal flue does get pretty hot though.

Have you fired them all up yet?

Thank you Alex for your links and pic

Do you use this flue for your boiler? http://www.autosiliconehoses.com/silicone-polyester-reinforced-hose-90-degree-elbow-reducer-102mm-to-76mm-15-colours.html

Only asking that because i will buy the same boiler.

Many thanks

It does get hot, but not 120deg hot having said that I havent put a thermo on it yet.

When using two it gets a little bit hotter but not much, The bulk head is warm though

That's correct, the Fogwash isn't great in this regard. I'd assume/hope that Alex's heaters are a bit more refined. It would greatly help in expelling hot gases from the van. I will eventually get the same heater as him, but my Fogwash is still going great with no issues.

What's stopping the flue products from one boiler entering the other boilers and out through the bottom into the van? Totally possible on a windy day with the doors open. Will it take a CO related death either directly or through driving whilst CO poisoned before people stop trying to save money by being this foolish?

Can you please tell me how you would get CO poisoning if the van doors where open?

Hi Alex.
Basically if the rear doors are open and there is a strong wind blowing over your van in the right direction the  chimney/flue principal operating from the boiler can be reversed and the products are pulled back down through the boiler into the van. A wrongly placed roof light on a house roof near to a low chimney can cause the same effect. It sounds like you have a sealed bulkhead and the CO products will not enter the cabin. However many others are following your advice and may not have as good a barrier. The lack of condensation in the van indicates that the products of combustion are escaping safely for now. Keep an eye on things now you are running three boilers though.

Thanks Alex. I thought the exhaust got hotter than that - thats why I asked.

Cheers

I ran the same boiler for 2 years and there much gas from the boiler.I in the height of winter and been very cold would hold my face over the outlet and never felt any ill effects. 
I would not change a Fgg wash for then boiler made in China,the heat exchanger on them is paper thin were the Fog wash is a more heavy metal construction.

You do realize the Fogwash is made in China right?

What gas regulator do you use? I've had to change mine as it stopped working and found that the replacement will only manage one boiler.

I would imagine though that the fact that the doors are open means that there is good ventilation and therefore no one is in danger from CO

[spongebob]

Yes probably the case in your van. In others with holes in bulkheads though the cab could be full. All I know is that the pursuit of saving a couple of quid on the correct flue product combined with LPG gas safety or lack of it will claim its first victim soon. I can make more per hour cleaning than gas installing somedays yet it seems everyone on here resents paying to have the boilers installed for less than they earn cleaning.
I am perhaps being over the top but its always best to think of the worst case scenario. Unlike a lot of others on here with an opinion mine is informed.

are these 8L off the bay?

would one be suffice for 2 ops running at half  speed on the pump controllers?

Silicon hose is perfect for the boilers  heat/ fume vent. They can take a lot of heat. If one just looks at the  latest in oven baking trays they are all silicon. Silcon is second only to Teflon.

People die in tents from CO poisoning, so not sure you are right on that.

Because its sealed. And they are breathing it in over the course of 6 to 8 hours.

However to ease you troubled minds, I will fit a Monoxide alarm, in the cab and in the back

One would suffice.

The problem I have found with this using a 10l boiler is setup

These boiler ideally need to be calibrated to each pump, each hose and, each pole.

As soon as you add another pump its gets complicated.

Also when one user stops his flow, the other users flow doubles and then uses more water.

I got them from ebay

so an 8l on its own with own pump and controller would be good then.

i have a fogwash in one van
and want to add 2 boilers to the 2 man van set up. each op has own pump and controller

[Alex Wingrove]

It will work, but I wouldn't describe it as good.

You will get the water coming out of the boiler at a maximum of 50deg.

So this will mean 30deg at the brush head

 a link to the boilers please guys
