Someone posted a link months ago to one. I can't remember who. I'm unable to find the post using the search.
Can anybody help or post a link please ?

Thanks Adman. That's a shame. There are others but they look very cheap. What was good about this one was that it had a temp control. I wouldn't mind giving an immersion hot system a go and thought it a good way of "dipping my toe" without drilling a hole in a new tank.

that's a few weeks wait

You'll be waiting forever with a 2kw heater to heat say a 450 litre tank to 50 centigrade....around 12 hours or more.

This was interesting, would it be safe to just have it laying at the bottom of the tank with regards of the heat?

Got a 800l IBC tank that I want to baffle with Perforated Drainage pipe 25 meter.

If you start with water that's 10 degrees (rather than zero) it will take about 10 hours to heat up to 50 degrees.  But say 12 hours to be conservative.

Switch it on at 7pm, it'll be ready at 7am.

Sounds ok to me.

I'm downsizing to a smaller van and set up, 300 L tank.
Thanks for the info guys. Was just a thought.
If anyone with a bigger brain than me can estimate the time and temp a 2kw could heat 300 L to then please do

Yeah much easier to turn the diesel heater on and have 65 degree water in about 5-6 minutes from freezing cold water in the tank lol.

Very  predicktable

Either way m8 you will be waiting for ages for it to heat up and it will probably end up costing you more money to run long term,there’s only 2 ways to do it either a diesel heater or concept 20 gas system.
They will both give you hot water within minutes,actually I would prefer the gas as you can get the exact temperature you want as the concept system monitors the water temperature like your household system does with the thermostat.

From a starting point of 10degrees you're talking just over 8 hours to get to 50degrees.

[Richard Groves]

Thank you for everyones input.
I was just interested at this point, that was all.

My thoughts were it could be an inexpensive way to see if it would benefit me.
Even it were not used daily.  For  those days I have seafront properties , a day of booked first cleans or close to freezing temps.
I can understand how it would not rival a fully fledged diesel powered hot water system or be cost and time effective compared to one.

How ever you look at it I don’t see the point really you either want hot water or you don’t,if you could plug something in and it took half hour to heat the whole tank then fair play but this method takes hours and even then it may start off quiet hot but it’ll soon only give you warm water which won’t help with cleaning,it will give you soft hose though.

Fair enough and your reasoning is valid.
Like I said was just a thought.
But it is  your opinion.
I can't wait for Nathans reply. I've got the popcorn ready.

Takes me about 9 hours for a 350 litre tank, 2 kw immersion.
Loses very little over the day as the tank is so well insulated.
I have a temperature guage mounted on my control unit with a sensor in the tank.
Someone ought to talk to Heatrod, if they made a drop in immersion loads would buy.
You would have to use a fish tank pump to move the water around.

Lol like I said not worth the hassle

Thank you.
What temp does it get to and how much do you think the cost is per 9 hr ?

[James 77]

I was thinking about a 2kw immersion for my 650l tank, think I’ll wait for the diesel heater,the immersion would take forever to heat and cost an arm and a leg in leccy

[Spotfree]

Ive been using a 3kw over the winter, I havent been bothering lately as I cant see the point.

If I put it on for 12-13 hours it'll start to get hotish after the first few houses but I cant see the value in paying £6 per night , that over £80 per month.

The one place I saw a benefit was algae which came off easier, other than that it was just "nicer" to work with, thats all.
