Will heat 100 meters of
Hose and all internal pipes lol I think not,it's a bit like an L5 it's not designed to heat large volumes of water.

L5's are poop  compared to a fastar 8L.
And no I would not use it to heat the water in my two tanks as that would be just daft when it's designed for on-demand use.
However spring do a controller that has a frost protection mode built in that will turn on either a lpg or diesel type water heater if you wanted to go down that route. No idea how good they are as I've never bothered myself.

I've got the fastar heater. Dogs b******s. Now its been tweaked.

Had my immersion heater on overnight last night, water in tank is at 60 degrees,

get yourself a proper immersion heater waster of money and time with pond heaters, you need to change the title of this thread to "finally on luke warm water"

 
But saying that, surely 60 degrees is way too hot and would do damage to windows.
Im looking at just heating to about 34 degrees. At the moment im off work due to family illness, so ive a little time to play about. As i mentioned in first thread im not keen to cut into ny tank, im good at diy but it normally takes 2nd attempt to get right so i can see leaks springing here n there if i attempt it. My  replacement heaters are due today so will test it out tonight.
I am pleased with my tank insulation though, because since yesterday morning when i last took the reading and turned off the heaters, ive just been out to take a temp reading and it was just short of 20. So within 24 hrs and no extra heating in van overnight, ive only lost a handfull of degrees of heat .

60 degrees at the tank at the start of the day is not 60 degrees onto the glass, my immersion has an adjustable thermostat so you can turn it down if you dont want it that hot.

my tank was custom made with a custom immersion made to my specifications so not just some cut and bodge it job on the cheap

Out of curiosity, if 60 in tank what will it be at the brush end. Assuming your tank is well insulated as you said, i would be expecting it to be between high end 50's - 60 throughout the day.
My tank is insulated by myself and over 24 hrs i only lost 6 or 7 degrees in temp. So at 60 in tank what temp do you get at brush end on your first couple of jobs??
What is the highest regular safe temp to use on glass?? (Havent a clue, hence the question)

I used mine today for something a bit different. Just hooked up the inlet of the heater to an outside tap to add hot water to a softwash mix. Then used it again to rinse down the render walls etc with hot tap water... How cool was that

don't know I have not tested it with a thermometer,  I have never had any problems damaging a window with hot water, the temp at the brush is variable and depends on how long the hose is reeled out how much I have turned flow off etc etc either way its hot in the tank and hot at the brush

[Tosh]

I have water coming out the brush so its quite hot. The sort of hot you get out your hot water tap where its close to getting too hot. Not had a problem with any glass so far this winter. I bet it cools more in the time that it takes to get from the brush head to the glass than it does all the length of uncoiled hose lying on the ground. Partly because I use fan jets and that’ll encourage the temp to drop rapidly IMO.

[JandS]

Nathan....unless you running it constantly, and I mean constantly, through the pipes all morning and again all afternoon you will probably get about 66% of the tank temperature the rest will be lost in the hose length especially if your running 100m of it at this time of year over cold ground.
It will take a good few minutes at start up on morning and afternoon to reach said temperature so you will either have to start off cleaning with cold water or wait.
Depends on what you put the flow rate to but if you want it hot on start up you will waste a fair bit of water.
I use 60c hot water for carpet cleaning and over say a 20m run first thing it can take 90 seconds or more to get up to a decent temperature and that's hose run indoors not outdoors.

60 Degrees in the tank,what bull poop that is lol 😂

[NWH]

Mine comes out the tank through the DI and into the heater and if on 70 on the controller i don't get 60,for it to be effective in the cold any hot system has to have some sort of frost stat setup to keep everything warm i.e. Hoses etc otherwise you'll have a tank of hot water you can't get at cos all the pipes are frozen solid.

[Dave Willis]

Erm no, because the tank acts as a giant radiator and heats the back of the van. Put the reel hose in the top of the tank for a few minutes and pump until hot and you are ready to go.

Exactly, I use a 3KW immersion,  I open my back doors in the morning and everything in the back of the van is nice and warm. I have a 750 litre tank in mine, I will test how hot my water is on Monday.

why is water at 60 degrees in the tank so unbelievable?  this site is so full of morons its unreal sometimes

[Dave Willis]

Because you didn't spend three grand on some complicated system then it can't possibly work can it?

Fifty quid to get hot water? Impossible!

That's pretty rich from someone who up until last week didn't even understand how his controller works!

[nathankaye]

Well my heaters came or should i say heater and not the one i ordered either.

So last night put in one half of my tank the two 300wat heaters and the other half of the tank (500l upright wydale tank) a 500w steel heater.
This morning i took the lid of and felt the heat, so that was a good sign. In went the tds temp stick and got a reading of 40degrees. So put my hand in and its lovely and warm not hot hot, so i can see why it does need to be close to 60 to state you use hot water, but for now this will do me nicely.

[Splash & dash]

It doesn't matter what temperature you have in the tank or what the heater is producing temp wise , if you have 100 meters of hose on the ground in cold conditions it will rapidly reduce the heat of the water , if you are using just 20 meters it will be a lot hotter , I think the important thing is that it will be a lot warmer than than tap water making the working day easier , anything is better than cold water , we run the boiler flat out summer and winter , never had a problem breaking glass Evan on frosty mornings , in the summer we turn off the boiler at lunch time and the tank is hot for the rest of the day , I have never put a thermomiter in the tank but you wouldn't want to put your hand in it it's that hot

An element can work... but because of the amount of water we use each day it’s too dynamic.  Well that’s my thoughts...

And a waste of money....

Better to have a small greenhouse heater on each night to stop the freeze and warm the water by a degree or 2...

My heater packed in after 6 years on Monday and by last night my pipes were frozen...  not my reel or pole as they were in the flat but the actual pump and pipes... and that NEVER happened when I had the heater going overnight (cost £1 a night) and allowed me to work the next day EVEN when its 0c or -1c..

Que?  How is it a waste of money to have a tank full of hot water for around £2 per time when you spend £1 to raise the temp by only a degree or two? What exactly do you mean by saying an element is too dynamic?

[Smurf]

3 kw element in a decent size van tank must cost more than £2 to run each night surely?
