Tested my water today at a flow rate of 90 on the controller and the water was reading 67 degrees,I’ve been getting this kind of reading since I’ve charged the batteries overnight for the last week or so on a regular basis.
I didn’t realise you could crack glass in this kind of weather on PVC units but I did last week,must have been. a defect in that particular pane of glass,watch out Daz it can happen even in hot weather.
-
Surprised you do not charge your batteries every night as a matter of course. How long have you been using hot water?
-
Using hot water12 odd years or so now but I’ve only had this 9 kw for 6 months or so,I do 60 odd miles a day on average and have a mains hook up but I’ve been finding I’ve had to charge the batteries more due to them being 18 months old now.
It’s been turning off so I’ve had to Maine charge in to the side of the van every night and since doing this the water has been really really hot even with all hose out of the van.
-
Even doing 60 miles I would think your heater still takes a lot out of the battery. If it were me I would always charge the batteries overnight if using a diesel heater.
Glad it is working well for you.
-
Over the last 2 weeks I can’t believe how much hotter it’s been,it was hot enough before but I was only charging on average once a week.
Changing a brush on a gooseneck has been a challenge not getting my fingers in the way of the water in case I scold them lol,it’s too hot really I couldn’t use it anywhere near like it’s been last 2 weeks in the winter or frosty mornings.
-
I can’t understand why you need water so hot that it cracks windows, to clean windows ???
Are all your customers windows full of egg or sumat as my customers just have general dust , dirt and a few bird $hits
-
nigel your waters hotter because the weathers warmer!your starting temperature in your tank before heating will be higher.....
i always charge my batteries up every night,i only do around 10-15 miles a day though,i also have my van running at lunchtime to top up the batteries a bit for the afternoons work....
hot water systems are great in the warmer months,esp for the sticky pollen,baked on birdmuck,insect spots(little yellow spots) that seem to cover some windows(i clean a lot of windows in the leafy suburbs and some semi rural jobs surrounded by farmers fields)......
my waters around 50-60c at brush end which is plenty hot enough...
-
No Daz the heater is physically working better now I am having to fully charge every night,I’ll be replacing the batteries soon so I don’t have to plug in all the time.
-
You should be charging every night anyway with the load you are pulling off the batteries, that’s the key for long battery life !
-
Mine are on charge 24/7 😆
-
I honestly wish I’d have got the 5.2 kw. Lol.
Mine is scorching even on minimum after an hour or so.
I’m setting up a flow bypass valve though so I don’t have to run two pumps to keep the heater from shutting down. That should help me control the temp a bit more.
-

you must of knackered the batteries yourself then by discharging them too deeply, too often....mine are fine and are older than yours(fitted by grippa back in dec 2017)....im sure you had your batteries fitted after mine....
-

correct!......you d have thought nigel would have sussed it out after 12 or so years of using diesel heaters....but apparently not..... ::)roll

just run one pump then jonny.......then you wont constantly have hot water diverting back to your tank all day unless your driving between jobs.....or just turn your heater off at lunchtime....
your heater wont shut down in between jobs if your quick.....mine very rarely does....
-
I had to turn mine off today even on minimum it was far to hot,I ran it when I was parked up on minimum got to another old glass job and it’s was still far too hot to clean older glass they were creaking.
I turned the heater off ran through the system cold for 5 minutes before I started work again lol,the weather is warmer I agree and my other 5kw heater was always hotter this time of year but the 9kw is proper hot lol lovely.
They work far far better with healthy batteries like you say Daz I probably have killed them off by now but when I replace them I’ll make sure I keep them topped up,still great of having the option of really hot water I did a weatherboard clean last week with very little scrubbing needed,next to no effort to clean off very stubborn dirt.
As for the 5kw I wouldn’t go for 1 of them again the 9kw is very hot but it’s much better have the hotter option if needed.
-
Don't tell me that you can't actually regulate the temperature on these things? :o
-
You can turn em down but I think when you’ve had it flat out in the warmer weather it takes a long time for it to cool down,honestly today the water was scolding hot almost to hot for a tea bag lol.
It would kill a softish brush in no time or at least reshape it.
-

you can on mine....if i turn the mixer valve right down on the side of the heater i get luke warm water at brush end if i want but i run mine on full blast every day as i like to have very hot water at brush end in the warmer months,this is where the real cleaning benefit kicks in....
in the cold winter months i still run it on full heat setting as heat is lost from the hose esp on cold/frozen ground with all 100m off the reel so i still end up with warm water at brush end....
-
I can’t run mine flat out Daz it’s far to hot m8.
-
I reckon Oliver’s popped a 5kw Heater in you’re cabinet m8 lol,I have been just as wary as if it was minus temperatures with the water from my heater.
I thought the needle in my valve was broken earlier when I turned it down coz it was still piping hot,I turned both exchangers down to minimum made very little difference if any.
-

Sounds like you have a faulty unit then. You are cracking glass in summer because the water is so hot yet the regulator has no affect on the temp! Sounds more like Oliver has fitted you a ringer mate!! ;D
-
Mine is boiling hot too. Almost to the point where the pole hose is too hot to handle.
It just needs regulating on the dial on the side of the unit.
-
Lol yeah I know the feeling it’s because of the recirculating back to tank when I’ve had it very hot,what I’ll do from now on is start it off on minimum recirculating it back it would have cooled down in the end but the exchangers would have been piping hot having it on full heat.
It’s not a problem on modern glass so much although you still have to be careful it’s the older glass you have to watch it on,if you clean roofs for free like me it breezes through em 😂

It should make a difference mine has two heat exchangers and it’s running 8 hours a day Ime just thinking about turning it down as I have had steam coming off the windows all day today , when it’s hot I turn the taps to minimum and it reduces the heat significantly, are you sure you have the needle valves in your s ?? It should alter it quite a bit . The hose the last few days have been so hot it’s been difficult to hold them whilst winding the hose in . Dazmond is right about ambient water temperature affecting the the heat output in the winter the water out of the tap may only be 5 or so degrees in the summer it can be 15 degrees before it goes int the boiler so the water will heat up much faster .
-
Winding in with no cloth wouldn’t be possible last week or so like you say due to the heat from the water,I’ve run it on minimum before and it’s been fine so it works on the lower setting.
Never thought I’d have to worry about cracking glass when it’s been 25 degrees outside.

your mixer valve is not working then......my water goes luke warm on min setting.....just like it should do...

thats normal for me on full heat setting on the warmer days(20c+)even with most of my hose off the reel.....
-
the starting temperature in my tank was 15c this morning just as i fired up the heater so it soon got up to operating temperature...it was piping hot by the time i got to my first job 15 mins away.....
what setting do you have your liquid logic controllers on lads?i find 40-45 is about right,still plenty of flow but not gushing out and wasting water...

60 for me. I like a higher flow rate.
I’ve got a 700 litre tank and that lasts me a good full day.
-
90 to flat out for me or 12 feet away out the end of the brush.
-
We run ours on 64 for windows more if doing commercial building wash downs
-
I think mines a 5-2 shurflo I run mine always on at least 85-90,if the batteries are fully charged 85 is enough.
I always use that flow even on regular cleans.
-
40-45 is a very high flow for windows on mine......
-
Full throttle for me.
-
45-50 lol dribbling are you Daz
-
80 for me !
-

That’s not how pumps and controllers work mate. 40-45 is running on less than half capacity/volume.
If it’s the standard shurflo pump that your using then your using considerably less flow than most on here. Try increasing your flow and you might get finished work even faster. ;D

absolutely not jonny,its gushing out at times on that flow.....its a water genie pump(im not sure what make it is actually).the jets of water are pumping at least 6 foot out of the brush,thats plenty....
i couldnt work faster than i currently do.....
-
That’s what I thought 6 foot at that flow,try 12ft and see how much better that is and how much quicker you can clean on that flow.
The kind of setting you have I hate hardly any water in my eyes on your setting.
-
Don't know what jets you guys use, but if you want a very high flow you should at least be using 3mm pencil jets instead of the 2mm most seem to use. Using 2mm you must get a lot of splash back and spray.
-

seriously you couldnt clean faster than me..blink and ive cleaned a window! ;D
some controllers must be different as 40-45 is a VERY HIGH FLOW rate on mine....2mm pencil jets....
-
You are getting 6 foot out the brush you said that’s not a high flow of water in my eyes,I can’t believe actually when I see other people using a pole how long they take to clean a window or there method of cleaning 99% of the time it’s complete overkill the way and the time they take.
-
YouTube is full of WFPole videos where the people cleaning windows are cleaning maintenance cleans like a first clean.
-
Its also full of dodgy peeps that think the way forward is to reinvent the Dodo.

It must sting a bit, though.
