Hi Guys, just out of interest, and don’t want to start the usual!
What’s your temperature at brush head?
I know it fluctuates with the weather but let’s say on an average day this month.
I have an immersion, only because: a) a diesel heater wouldn’t fit in my tiny Bipper.
b) at 71 I can’t really justify leaving my son a heater in my will😂
Cheers.

I’ll take the temp later and let you know I’ve turned mine off for a couple of hours as I’ve been doing insides.

Temperature at the brush will vary  from job to job depending how much hose is out and ground temperature but I would say anywhere from 50-80 degrees , is a mean average

[combat1]

Thanks for that, quite a difference to mine!
I shortened the hose as I only need a small amount. About twice a year I just Clip in the extension for massive houses.
My brush head temp at 16.30 was 30 deg. Hotter at start of day but nowhere near 50.
Thanks

The 9kw produces very hot water at the brush I didn’t get chance to see what mine was today I’ll do it tomorrow,last time I checked it with a handheld it was around 60-65 degrees with a fair bit of hose out lovely to work with all year round imo.

The disadvantage you have Combat1 using an immersion element is that the water is possibly warmer at the top of the tank than it is at the bottom. Even if driving mixes that water up, the warm water will rise to the top of the tank and you will draw off cooler water.
I can measure my hot water as it exits the diesel heater. I have regulated my mixer valve so the water temp is around 51 degrees  C at the heater. At the rear van port that water is hot to the touch. At the brush head that temperature changes from reasonably warm to luke warm depending on the outside temperature, which hose reel I'm using (one reel has microbore and the other minibore) and the amount of hose out.  It also changes with what the hose is laying on, ie. grass, stone or paving.

The only thing you can do is measure the temperature of the water going into your hose reel and compare it to the temperature of the water exiting your brush head. That differential will be the same with a diesel or gas heater. What I'm saying is that if your water is 30 degrees entering the hose reel and 20 degrees at the brush head, those figures will be the same with any other form of heating at that moment in time. We also find that to begin with, it takes a while to heat the hose up, so the water gets warmer the longer we run the pump for.

With diesel or gas heating, we are just heating the water we are using - heating on demand, so that's the main benefit. You are heating a full tank of water, but you may only be using 1/2 of it on a particular day. It reminds me of night storage heaters. You have to switch them on the previous night in expectation of the following day being cold.

Spruce I’ll check my water temperature tomorrow but it’s hotter than that I’m sure it too hot to touch a lot of the time even when I turn it down.

I cleaned my van today after work and my water was too hot to put my hand under it...I reckon  it was 65c-70c at brush head....

I had all of my 100m hose out 3 times today and it's probably around 45c-50c at brush head as i lose heat through my hose when none of it is on my reel....it'll be even lower on cold,frosty ground in the coming months....

Our temperature mixer valves are set just above minimum. So yes, I can turn them up higher to get hotter water out. It's just where we are running them now.
 I have been running them set up this way for a while. The change in water temperature at the brush head is apparent when running my fingers across the bristles to clean them, and very dependent on the conditions at that moment in time.

Thanks all, very interesting.
I didn’t think it was going to be that high!
60 deg in my tank this morning.
I would love a diesel heater but for my investment I’m well pleased with the immersion.
Thanks again to Spruce for the detail, appreciated everyone taking the time to give helpful answers.
Have a great day all.

Mine is totally variable, Luke warm to touch, up to scalding. I usually run on minimum which gives me Atleast 40 degrees. Then for upvc I can crank
It up and get 70 degrees easily.

Ice, snow and sub zero forecast at the end of next week…….Wonder how many hot water threads we will have this year.

I just leave mine on max all year round

[NWH]

Mines on minimum unless it’s a plastic clean usually it’s very hot on the lowest setting,lovely stuff 👌

probably not as many as hot water users sitting at home saying its too dangerous to drive when there's a dusting of snow and its minus 2

These younger window cleaners will not be able to relate to the implication of this statement. My last SLX22 lasted me 9 years. The top section and clamps needed replacing. I replaced it with an SLX27 and I still wonder if the pole will out-live me or not if it lasts 9 years as well.

When I was running my 04 plate Citroën Relay I was very aware that underbody rust and rot would lead to an MOT failure at some point. The MOT inspector, who has done our MOTs for the last 20 years would always question whether the van would outlast me or me the van. The last MOT he came to me as asked if I wanted to hear the good news or bad news first.

So I asked to hear the good news first. "Well, you have outlasted your van."

I then asked to hear the bad news. " You have outlasted your van".

I knew it was an MOT failure before I even took it in. I was surprised when they passed it the previous year TBH, so expected it to fail the last test.

Love it Spruce! I think I might just outlive my van.
I suppose I should build my business and bequeath a super van ( with heated seats!) Gardiner pole, electric reel and diesel heater plus a round that pays £300 every day 😀
At the moment he’s convinced he’s the next Ronaldo so the round might come in handy⚽️

At the rate the Government is falling out of love with diesel and in love with EV, then there is a possibility that most of us will outlive our vans.

Electric vans have a long way to go yet especially VWs I watched a short film on someone who had one for a couple of weeks he had the peogeot SWB version and it’s range was about 200 miles which is easily enough,I couldn’t get over the fact that plugging in at home for a full charge costs £10  per night or free from some charging points if you can find one anywhere.

They will eventually force electric technology onto vans by taxation and popular opinion, but I believe the biggest issue is the thousands of 40 ton lorries on our motorways every day.  I doubt there will ever be an electric solution to those vehicles.

Diesel is still being painted in a bad light even although the latest models aren't the dirties of polluters. Personally, I can see a switch to Hydrogen in the future if the world carries on as it is now. The electric drive isn't sustainable imho.
