It was the 9.1kw diesel heater, battery, 100m hose, battery case and installation.
Yes I know what it was like when I started out you have to build slowly , but Ime sure in time as you get more work and get well established things will change , it’s good to plan ahead .
The streamline system has the smallest footprint of any of the current webasto style heaters. You can of course buy the components and install them where you can - that’s what I did for my first install.
I like that idea. I think that would be quite easy to link in to the tank outlet via pump, flow sensor through Willis jacket with 2kw element then back to tank top. No drilling tank, just need an additional pump and pressure/flow switch to ensure flow maybe add in an extra thermostat in case flow stops. Why has no one mentioned this before??????
I was the same and saved up till I had the money and just went for it. Bought the £10k RO, twin electric reels hot water system which comes with a speedliner thrown in. A lot of folk on here were saying I didn't need all that because I had 50 customers and they were right. The only thing about this game is we are all heading in the same direction. In the fullness of time we want to make the job easier and hot water, electric reels and a light pole makes all the difference. I make about £900 a month from windows but my system cost £600 a year to service which I could do myself bar the Webasto heater. I much prefer getting Oliver to service it each year and if anything goes wrong then he is only an email away.
The hot water is good for cleaning conny roofs which is another job you flung my way. Got a nice present for you next time we meet ? a battery light which is good for late afternoons up here when the weather is dreich.
I treated myself to a retro fit grippatank hot water system 3 years ago for sticking at window cleaning for 25 years!??
They would be some limited convection within the 25 litre drum as the warmed water moves to the top of the drum and the colder water sinks but this would not circulate through into the main tank in a sufficient degree to warm the tank.
I have a 650ltr Wyedale flat tank. I switch my 2kw immersion on in the late afternoon/early evening. I get 60~65c. The immersion is only about 4 inches above the bottom, near the corner. I don't think you'll get quite that temperature with being higher up as the thermostat will trip In and out depending on the temperature at its own level. The tank will heat from the top down till the thermostat takes charge of the situation. Doesn't cost much more to put it on early as once up to temperature it will kick in and out very infrequently. This is of course provided there is a very good job done on the insulation.
I have not used an immersion but if it’s 3/4 down the tank it should be fine just make sure the element isn’t touching anything , preferably use a 2kw as the 3 kw will need specialist wiring and can over heat the electrics , I have no idear what temperature you should get but if you can insulate the tank this will help keep the heat in
3/4 will be fine, the convection will heat all of the water. 9hrs with a 2kw will raise the temp by about 30-35 degrees
Immersion elements generally have a built in thermostat, as long as a fuse is in line and the weakest point of the circuit it poses no more of a risk than a standard immersion. I have a 3kW immersion in my tank, it’s a flat 650 litre tank that is only 30cm deep with multiple baffles throughout. I’ve had to put a pumped loop circuit in that takes water from the top of the tank above the immersion to the opposite corner on the far side. This distributes the temperature really well and creates a natural convection current. I’ve set my heater to 45-50 degrees as that works well for me. I started at 65-70 degrees but didn’t see any benefit with the higher temperature - plus I can still just about get away with using any brush I like as the hot water brush selection is pretty cr4ppy. I didn’t follow up in the Willis jacket approach as my tanks have an immersion boss welded in - if they didn’t it would be the way to go for ease of installation. The only drawback would be a pump would have to circulate water constantly and you’d have to be 100% sure the element is completely submerged in water (that’s why mine didn’t work as I kept forgetting to check I didn’t have an airlock and the element blew). I’d probably look at getting an oversized Willis Jacket if I was to test it again - so a 16” jacket with a 14” or 12” element, I felt the sleeve didn’t seem to have much circulation room inside but maybe that’s the point ?
