As above , with all the talk lately over immersion / diesel methods , what do people find that shocking in the likes of the L5 gas method ?
I really am at a loss as to why people see/find it so dangerous to use ?
Any comments welcome chaps .

I have a question for you P & F:

When you are using gas to heat your water are you circulating some of the water back around your tank whilst cleaning the windows or straight through to pole hose only? If pole hose only , does the heater cut out straight away once the water flow stops when finishing a house.  I tried gas once and it blew the hose to pieces with an almighty bang 

[P @ F]

What you mention is one of the things that have to be addressed first when setting it all up , no reciculating is involved in my setup , its right out of the boiler and into the hose reel .
I did have an issue in the early days when  the pump did keep running for too long and cause lots of pressure within the system , this would result in over expansion of the hoses or i suppose super heating the water that is trapped within the heat excahanger of the boiler .
I got around this by firstly getting the DE settings correct on the flow controller , but more importantly having a suitable hose from boiler to reel , i tried normal hose which blew up like a modelling balloon , then onto washing machine hot feed hose , this was way better but still not ideal , now i will only use high heat steel overbraided hose , this is fantastic as hardly any expansion is possible .
You will still get expansion in the delivery hose , but its down to what you run as to how much expansion you get , i run 100 m of Gardiner green as main and pole hose via tubeless , and that stuff is the dogs danglers with regard to hot water and expansion  is minimal as its damn tough stuff .

I had a 'Dazmond' in my van once with my first L5. Not to be deterred a few years later with my current van I decided to fit another L5. On reflection the thought of a repeat experience was what made me decide to go with a Grippa system. If you get a half decent explosion you probably won't have a van left if it blows to its full potential.

Forgot to say that the cut off time is not much longer than if using cold water , maybe 3/4 seconds tops .

OK , so you too had a Dazmond , but what was the outcome of the second L5 fit out ?
Did the cause of the first failure ever come to light , if so , what was it ?

Nearly set fire to my van. 

Checked the gas pipe for leaks every week or so, but one day it Turned out a small gap at the gas inlet managed to somehow catch on the burner!

Thankfully I was at the van to notice it.

Threw the boiler away after that. They really aren’t fit for purpose in my view, and I’m yet to find an insurance company who will give it in writing that your covered. Working away and out of sight from the boiler etc.

OK , so you too had a Dazmond , but what was the outcome of the second L5 fit out ? Considering the history of my first unit I saw no reason why it might not happen again. I felt uneasy using it, unsettled, expecting to see a mushroom cloud appearing over the roofs of houses I was cleaning whilst round the back of various properties.


Did the cause of the first failure ever come to light , if so , what was it ? Yes, there was a gas leak. It wasn't ever tracked down or analysed precisely because the experience was sufficient to convince me, albeit it temporarily, that the unit was crap, a liability and dangerous.

Its trying to do gas on the cheap that seems to be the main problem, I have a on demand gas water heater made for a campervan
(Trauma the latest model would cost around a grand ) if I wanted to use hot I wouldn't think twice about installing it.
Not installing a proper flu would be another cause of the Dazmond type bangs.

And in camping aren’t the cylinders stored external from  campers or caravans in a well ventilated box so any gas can escape

The problem is that the gas used is its heavier than air so if it leaks it tends to sit at the bottom therefore the vents need to be close to or on the floor, that's how they work it in campers and caravans.

We keep coming back to these heaters the truth is they are not designed to be given the hammering we do,I had 2 they looked like they should have been on sale in Hamleys toy shop.

Unfortunately that won’t stop
A gas leak at the other end of the hose. The gas hose that enters the heater. That’s where most leaks seem to come from.

Just seen the news suicide bomber caught with an L5 heater strapped to his body 🧕🏿

[jonny thompson]

I’ve been using a gas heater for past 5 years, never had a problem, wouldn’t be without it

[P @ F]

That gasstop thing , i assume it can sense when there is a break lets say in the gas hose , it senses a bigger need for gas and assumes a leak so shuts the bottle off , is that correct ?
But as its fitted before the regulator then how does it know becuase the gas would still be regulated surely , even if it was escaping after the regulator and before the L5 ?

I just had a look at my old van pics and i can trace my L5 back to January 06 , im still using it now , with no issues at all .

[P @ F]

Nah , you better scrub the Jan 06 bit , must be a prob with cam date as van was pink in the picture , in 06 it was still white !
Got me thinking now though !

According to the literature and the FAQ its designed to stop a "major leak", if it senses more than 110% of normal flow it shuts off. But its also capable of testing for leaks, i'd of thought that was something you should do with a flexible hose often anyway.
