Running a 2kw on a 13amp socket would be just within the allowance but if running it for 10 to 12hours every night you would be
safer getting the electrics upgraded.
A 2kw heater will up the temp of 500ltrs by 50degrees in 14.5 hours with absolutely no heat escaping from the water , there's no possible way of improving on this, science fact.

I will put my immersion on tonight ( if I remember ) I will post my results tomorrow, both the starting temp at night and the temp in the morning and how long the immersion has been plugged in. I have a 3kw immersion and had an electrician upgrade my electrics in the garage. I very much doubt the results will be able to match the heat of Nathans water.

This should be interesting.
I dont belief mine is a 3kw 27inch element at all. If it is then i got a cracking deal on price as it was cheap as chips. Also my standard heavy duty oranges extension would be really warm,,,,,dangerously hot in fact.

If my tank is being filled virtually from empty from my outside ibc tank than i would run the heater for even longer as the start temp is around 16 degrees.
But by the end of the night, as shown in so many of my public videos, the water temp by 8pm is around 40 - 50 degrees. Whenni top up with the cold my starting temp is around 38 - 44 degrees. Which then dictates how long i turn the heater on for.

Complete rubbish a fuel tank worth of diesel to run a top C over a month lol,I use about £25 worth of diesel in a separate tank next to the heater every 4 weeks or so. You preheat as said on the way to the first job to get it up to temp and by doing this with the van running it uses no static battery power then,be careful on frosty mornings though mine was at 70degrees pre heated at the first job this morning dropping to around the 45-50 mark it was smoking off the glass no hiding your using hot water,hot water is the only way to WFP imo hot means cleaner Windows.

Thanks for your input with regard diesel usage over a month. User experience is worth much more than written down theory.

I just used Webasto's figures of 0.59 liters of diesel an hour on full throttle. Webasto give 0.30 lph under reduced throttle. (I excluded the reduce heat consumption.

I worked on the assumption of 6 hours a day 5 days a week and 4 weeks a month = 70 liters using full heat mode. That's what my van's tank holds.

What tank do you use to fuel your heater NWH?

Thanks

Hi Nathan
As I recall my 14 inch was about £80 ish 2kw.
Today was the first colder day, orgasmic as the steam comes off the glass!
I only have a 350 tank so tend to heat for a few hours in the evening then about 4 hours early morning.
Was 60 in the tank and 50 something at the brush head.
I usually heat to about 44.
Before people start laughing I can tell you that both green algae and snail trails disappear with no effort.
Also rinsing is so fast and hoses lovely and supple.

[NWH]

I use a 25ltr container from a caravan center the 2 opening version 1 small screw lid with a hole drilled for diesel the bigger screw lid with a small pipe for air out. When all is good and tbh honest if I new what I know now I’d have had very little problems with it,they are very reliable there’s only 3-4 things that need replacing on them and they are like triggers broom all can be replaced by yourself. My recommendation to any newbie would be get a thermo too C. Version heater they literally cost peanuts to run on diesel,5-£6 a week that’s it.

[NWH]

For cleaning Windows you don’t need anything that heats water hotter unless all your cleaning everyday is cladding even then it’s hot enough,gas heaters are more to run and not as reliable from people I know have them and they have the purpose built models made for window cleaning they wished they’d gone diesel. The only thing with gas is you can get the temp more accurate.

Is all this heating malarkey worth the cost of buying? cost of running? Increased risk to home and van?  Faffing about ?  Breakdowns?

For what? Warner hands, faster getting bird poo off, getting out an hour earlier on those rare frosty mornings.

Do you actually clean any windows Nathan ? you have a 500ltr tank and its still that full at the end of the day  when topped
up with cold it only drops a few degrees, to be honest your nothing more than a bad story teller which is why your not worried if
your element is 3kw or not.

Yep!!  For me its about comfort and as you may know, i have the hose around my waist and in this cold weather its lovely!!

Im gonna post it later, but the temp in my ibc tank today is a very cold 11.3 degrees. Ild hate to be using that with stiff hoses and then on a very cold icy day to lay an already cold hose on top of a very cold icy ground doesnt sound like fun to me.

But cleaning wise, its faster and very effective on pvc frames. Certainly good for first cleans and also no need for chems on fascia or conny roof cleans.  Then theres the spider poo etc or even splattered concrete. Ive used hot water on conrete to successfully remove n clean.

Keep watching this space dry clean for when i post the pictures. At mo im getting kids to bed but lets see what the evidence shows.
Also if you have nothing better to do please find the post where i showed the receipt of purchase for my very cheap 3kw 27 inch heater.

Please also enlighten me as to what im gaining from this by spinning a tail?? So i can be called that bloke with hot or the hottest water 😂😂😂😂   cant you see how ridiculous it is. Im gaining jack all by lying

Not really, I just soak it and then with my finger nail I brush it off.  The hot water really softens it.

Ok, so just to repeat this mornings vid showing start temp of water at around 10am.
https://youtu.be/J2XqZ3l1PUE

This is how much water i had left by end of night and the temp of said water.


This is how much water is now in the tank and again the temp of said water. (However the tds stick is a little fogged up, but you might be able to read it still. If not ive wrote it on.


Im sticking it on early tonight at 8 pm till 8am or 8.30 pending how the morning goes.

Thanks for your input with regard diesel usage over a month. User experience is worth much more than written down theory.

I just used Webasto's figures of 0.59 liters of diesel an hour on full throttle. Webasto give 0.30 lph under reduced throttle. (I excluded the reduce heat consumption.

I worked on the assumption of 6 hours a day 5 days a week and 4 weeks a month = 70 liters using full heat mode. That's what my van's tank holds.

What tank do you use to fuel your heater NWH?

Thanks

In my experience Spruce, you're not far off. I have a 25 ltr tank which I can get about 20 ltrs out of before it drops below the output level. I have to fill it about every 7 working days, so about 60 litres a month. That's running permanently, sometimes full blast, sometimes tickover with no bypass fitted. If I don't mix 4 litres kero in with the diesel its a disaster, smoke everywhere. I am  running a thermo 90st though.

Your ST90 will use more diesel than the Thermo Top C . Webasto quote 1.1 lph on full heat mode, but on the lower heat cycle it could use much less than the Thermo Top C in the same heat mode (0.19 - 0.9 lph.)

I think the ST90 is more suited to window cleaning provided you can bleed that little extra heat off to stop it entering it stop/start cycle. If you have a 2 man system and there is only you, then you can run you second pump on slow and bleed that extra heat back to the tank. I have plans to add a third heat exchanger and trigger a third pump using a digital heat controller to do this.

What tank are you using? I think one of the problems is trying to find a suitable tank that has a fuel guage on it or that is opaque so you can see at a glance how much full you have left. If the unit locks out due to no fuel then it can be a palava getting it up and running.

Where do you buy Kerosene in small quantities from?

Here are the temps in my tank this morning.......I have a 750 litre uninsulated upright tank, I filled it with approx. 500 litres from my static, the ambient water temp was 15 degrees before I plugged in, using a 3kw element from 10pm - 7.30am the water temp has risen to 48 degrees at the top of the tank and 45 degrees at the bottom. This is fine for me as I use backpacks so not as much heat loss running the water through 100 metres of hose.

Exactly no real surprise there as it fits with the science, maybe after listening to you Nathan might give his head a wobble and
for the sake of safety get his element checked out, I doubt it though.

So in 9 hrs from a cold start of 15 degrees it rose by 33 degrees.
My starting point was quite warm at 39 degrees so the heater didnt have to expend its energy in heating the water from cold. I turned my heater on from 8.30 pm untill 8.30 am.  So my water if using a 3kw 27 inch should raise far more than 33 degrees?
So what would you expect it to be?

Firstly Nathan a kw is a kw no matter how long your element is.
To raise the water by 33degrees from any starting temp the figures are,
500lts 1kw 1153mins or 19.2 hours
500lts 2kw 576mins or 9.6 hours
500lts 3kw 384mins or 6.4 hours
These are all the maximum possible figure and don't allow for heat lose and slight differences in temps throughout the tank.
Therefore going by your findings your element seems  to be around the 2kw mark.

[NWH]

That is to much faffing for me I turn my heater on and in 5-6 minutes I have hot water I know your saying you just plug yours in and it’s heat Nathan but I pre beat mine on the way to the first job and it’s piping hot when I pull up and get going.
