I added the flue for the third boiler tonight and added the fire proof sealant aswell.

Here are a couple of pics.

Did you install yourself the flue through the roof?
Thanks

Very, Darren, Very.

3 boiler are  for solar work, we use 2 every day however.

I fitted myself, with the right hole cutters its very easy to do.

I got them from ebay, they are the 8l ones, and they are the best I have ever used

Many thanks

One hole for one flue. These are carbon monoxide producing devices. If you employ anyone you could be jailed for manslaughter if that went wrong. This same installation in a mobile catering van which is subject to council inspection would have you prosecuted by the health and safety executive. If you are taking this vehicle onto commercial cleaning jobs/sites then you could run into problems if anyone sees it.
It's your business but be careful.

Lot of joints on that gas pipe - is that wise? I don't know.

If they are 8l boilers and most pumps put out 5l max - could you not run two hoses from one boiler or is it too much? I'm guessing nobody uses 5l a minute due to hose diameter.

[Lee GLS]

I use a 6L with 2 pumps and have the heat setting just over half way, that Ives me 40deg at the brush head.

I can possibly understand have 2 if you use a high flow rate, but having a third boiler seems a bit of an overkill

Hi Alex

It looks as though you have used silicone hose elbows on the exhaust. Will those be able to cope with the heat if you don't find me asking?

[spongebob]

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?

[Michael Peterson]

It will be hot heat rises it will go out the top not sneak it's  way down and out into the van

[robert mitchell]

Depends on tbe type of flue .

The wind blowing in an open flue could overcome heat rising, I have no idea if these boilers are fan flued or open flue , prob best to ask an expert .

[C o z y]

Here's an old boiler from near to where we work.






  I'll get my coat

Where did you get that pic of my mrs ? 

[Dave Willis]

Can you run three appliances from one gas regulator?

Pic of the roof vent please.

I've got a hard enough time exhausting one boiler through a mush room vent without getting moisture in the back, wonder what it's like with three going through one exhaust. Next up for me is installing a Flettner.

The 8l refers to the maximum flow that this boiler can cope with, not the minimum. With the pump on full these boilers are only capable of heating up the water to  50deg.

The 5l even less so,

The kw load is very low on these boilers and the gas bottle is capable of feeding all three with out freeing up.



The third boiler is not over kill if you have three pumps using 2l per minute each.

Check out the operating temps here. The gas temp doesnt get any where near this. Also the alloy pipe.

And fire proof sealant.

Considering heat rises, its not an issue. Secondly I don't stand next to the boiler when its pumping out. I am busy working. As you can see I have a bulk head which is sealed.

A gas fire gives off more Co2 that these do, but people use them in sheds etc.

Side effects none of which I have suffered from over the last 4 years

headaches
dizziness
nausea
breathlessness
collapse
loss of consciousness

These products are not sealed. Not all the gas escapes through the flue. Thats why they are intended for outdoor use.

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

I haven't had any moisture inside the van yet. This suggests to me that it is well vented
