i am just getting used to using my hot system but am a bit afraid of turning temperature to high and cracking any glass in this cold weather, what temperature are others finding ok to use i am after the temperature of water at brush head.

Thanks

You are wise to be cautious.

Early mornings exposed glass can be minus eight- after nine am its usually warmer, and it's sudden temperature difference that causes problems not your brush head temperature.

A quick all-over a pane and then back also helps minimise thermal shock.

This is an art not a science.Think warm rather than hot, or even just not cold.There are also some negative perceptions from the customers- such as 'the decorator told me hot water is bad for my frames'. Once they have these ideas in their heads no anount of explanation will do and you can end up losing work. I have probably been hot on domestic longer than anyone on here and recently when i had the new van signed instead of saying hot it says heated.

Slumpy I never knew you were hot. 

Is that right?

[Clive McDonald]

You are joking.

I've only mentioned that i was the first to rig an on demand system a million times.I posted on here and drew a blank years ago, and then made it work. I predicted that most would switch but got flak so shut up.

My system is the simplest and the best always has been, and this is borne out by it's touble free longevity.

I did think it was a great marketing tool, but was wrong about that. When i make these posts about being two or three years in front thats what i mean. Ditto the electric reel.

There are only so many hours in a day and our job is too hard.Anything that makes it easier, slx-hot system-electric reel, costs money but pays for itself.That's what most of the disagreements on here are about, people like me who prefer to invest and work less hard, and people who want to minimise ex's.

You are joking.

You're right, I was

Well, i'm sure people enjoyed being told again, just as a classic steptoe and son or only fools and horse gets repeated, i'm quite sure i qualify on this basis too.

Perfect, you have a choice a retro fit diesel hot box at about 2.5 k with daily running costs of £8 for diesel. Or an on demand lpg system at £2 a day for which you have to buy a suitable heater.
The heater most used is called an L5. i believe the lads prefer this because it is cheap and has auto ignition. I use a rinnai 54eu, but several heaters suitable for caravans would be okay.

For simplicity the water on my van is zero tds and i do not carry a di.

We are not allowed to give advice on this because of the legals and it must be connected up by a competent person.

The only drawbacks i can think of are that you have to use a high flow for the heater to ignite.With a two man op this is not so critical.

Some such as nat have made adjustments to work on a lower flow.I Have a back to tank bypass controlled by a tap and use car heater hose after the heater.

In the winter, when it's very cold you have to drain the heater or it will freeze and break.

Slumpy, the thing I dont get about connecting it up by a competent/qualified person is that gas heaters on BBQs are NO different to what we use but some plonker with 10 pints of Kronenbourg can legally rig one of those together with no more qualifications than an NVQ in how to sweat with a string vest on.


I didnt get mine connected by a plumber, I used to connect my mums portable gas heater up in exactly the same fashion as one of these L5s when her gas ran out at home.




Oh I forgot that bloomin' nanny state again.

[Clive McDonald]

Me and Nat used to argue about this. He even sold  guides on ebay.

Giving advice on this is illegal. The people who enforce this would prosecute.

What even saying 'get a corgi registered plumber?'   

[Clive McDonald]

Yes corgi is gone, it's a new body now.This suits me the fewer that have it the better.



You do need a sticker.

Matt,

Whats with your website link?

Dean

Im waiting to be asked to change it 

However in the meantime Dean, please feel free to click on it and follow as many links as you like on it

Fitting a thermostatic mixer valve alleviates the low flow problem.

Mine has a max setting of 46 degrees C, which is ok for for window cleaning and keeps the temperature constant no matter what the flow rate.

This said, the lower the flow rate, the more cooling occurs in the hose.

I've posted about these about ten times over the last 2 years and I'm amazed everyone with a gas heater isn't using one!

Matt do you have a L 5 for your heated water.
