@Clean zero. I dont mind Conservatories like that, as long as not stupidly awkward..I use hot water most of the time and like a challenge like the con roof it’s great when you have finished and stand back and give yourself a well done .Roofs like that one you charge accordingly and explain why it is costing so much and when the customer sees the results they are over the moon and I get a lot of recommendations through it .Yes hard work but golden rewards which is what you want
TFR and degreasers don’t kill off the spores behind brackets etc hypo does and turns it to slime it reduces the amount of scrubbing dramatically and speeds up the job time .As would de greaser or Tfr.
I know this is an old post but I've finally had my webasto hot water unit fixed and is purring like a cat. ive got the vitron charger installed which is awesome charging my battery, but what I want to know is, do you think I can get away with just using my primary battery (115Ah) which powers my power reel and pump, to keep my hot water unit going for a 7 hour day?We do 4 weekly cleans on the coast that the glass is opaque after 4 weeks seagull poo sticks like glue it cuts the time in less than half using hot in this type of work .it’s not cheap I accept but it’s still cost effective .
@spruce is the technical guy and will explain it far better than me but don’t think that would be enough amp hours I think you would be draining the battery to muchI know this is an old post but I've finally had my webasto hot water unit fixed and is purring like a cat. ive got the vitron charger installed which is awesome charging my battery, but what I want to know is, do you think I can get away with just using my primary battery (115Ah) which powers my power reel and pump, to keep my hot water unit going for a 7 hour day?
Or do you think I need to daisy chain a secondary 115Ah battery? How do you have your battery system setup for hot water?
Thanks appreciate it.
This is one of those "how long is a piece of string" questions which depends on so many factors.I know this is an old post but I've finally had my webasto hot water unit fixed and is purring like a cat. ive got the vitron charger installed which is awesome charging my battery, but what I want to know is, do you think I can get away with just using my primary battery (115Ah) which powers my power reel and pump, to keep my hot water unit going for a 7 hour day?

Yeah i agree every system is different. Ive migrated to the pure freedom hot water elec reelmaster, fixed ontop of my 500L cube tank.This is one of those "how long is a piece of string" questions which depends on so many factors.
I tend to do what a supplier recommends as their experience is better than mine. If Grippatank were supplying a diesel heater and electric reel, they will supply 2 Numax combo leisure batteries and link them together. The combo battery has CCA rating.
I believe that the controller made by Spring Europe fitted to the p/f reel will dampen the initial milliseconds short when starting the electric reel. Maybe Ian Sheppard of Spring could add his input. It's this high DC current draw that I would be concerned about with my heater. @Ian Sheppard
What we do know is that @dazmond has been running a 9.1kw diesel heater supplied by Grippatank, a Purefreedom electric reel and his pump successfully for many years with 2 x Numax leisure batteries, a b2b on board charger and a top up charge every night to fully recharge his batteries.

Ive daisy chained my original 2 leisure batterys that xline fitted (both same manufacturer and volts) so my vitron charger positive cable (which is fused) goes straight to my heater battery, then short positive and negative cables attached to the battery that powers my pump and reel, that same battery is earthed to the van wall.
This was all down to google research, ive tested it on my driveway it seems to work fine, but the real test will be when i do a full day cleaning next week.
despite having a good b2b charger using thick 16mm 110amp cabling, im still going to hard charge at least my heater battery fairly regularly, especially in the winter months, as the cold canes the battery and more times than not, because the cold has depleted my heater battery sitting on the drive the frost stat doesnt work so doesnt protect my hoses. All fun and games. I want to make sure frost stat is gonna work on those frosty nights so i dont wake up to frozen hozes & pump - which means hard charging battery overnight (common sense tells me anyway)
One thing which has stumped me a bit though…my 5kw xline hot water unit which was fitted in may 2020 (used roughly about 18 months part time before the thermo top evo broke) xline guys put in lime antifreeze, they told me to not let it go below half way, then i bought prestone premixed (50/50) topped it up same year, a further several months later and the coolant level never went down. If it doesnt need to be topped up regularly, then how do u change the coolant round for fresh antifreeze if its been in the unit/resevoir for years.
I dont know whether im barking up the wrong tree, but ive been testing my now fixed hot water unit for past day or so now, checking temperatures, cleaning my own windows etc, and it can be random temperatures. One minute its tepid, next its hot, then next it goes down to lightly warm…is this something to do with my antifreeze thats been in there for 3 or so years? Ive looked inside and the coolant looks clean.
Then stupidly i went to my v11 controller to the temp (frost stat temp cage dangling externally off my tank cage) to see if i can change the temp of the water from the controller, it was reading 10c then as day went on went to 16c then dawned on me that it was the temp of the back of the van lol! Changing temp from the controller would just be too logical and easy after all!
The only way i can change the temperature of my water on the xline webasto unit is the temp gauge on the unit itself which is annoying, but even adjusting that periodically didnt overly make much difference, even when adjusted to ‘high’.
So would this issue be ‘old’ coolant? Or is this normal? Even on ‘high’ setting ive struggled to get over 40c when my unit should be able to get well over that.
Btw i tested the water for about an hour at home.
I just dont know why after 5-10 mins of startin the heater goin to toasty then shortly after goin to tepid or lower.
Good idea. Less messy than removing the hose from the heater inlet.I used my wet and dry vac and sucked all the anti freeze out of my header tank and replaced with fresh earlier this year
This is possibility number 1 of the heater shutting down and then restarting as you say.Antifreeze wont effect the temp out of the heater. It's just there to stop the coolant freezing and to prevent corrosion of the internals of the heater and pipework.
As for the temp going up and down that could be due to it shutting down and then restarting between jobs. Some systems have bypasses in so when you shut off your pole the heater continues to heat water and puts it back in your tank, therefore never shutting down. Other people plug their hose back into the tank so again the heater is still heating the water. I don't think these heaters like switching on and off frequently as startup tends to use a bit more diesel and can, over time, clog the combustion chamber with excess carbon, plus startup pulls a lot more amps than when it's fully running.
Just so you know, when you parallel up the batteries any current you pull comes out of both batteries i.e. if they are physically connected +ve to +ve and -ve to -ve then it's effectively 1 battery. The wires connecting between the 2 batteries should be the same thickness as your b2b and have a fuse in.
Definitely mains charge your batteries each night to ensure they last as long as possible.
ahh, someone else who has harnessed the heat from the exhaust, congratualtions, it seems people like yourself now find that you can get extra heat from that, it won't be long before the manufactuers will be clicking onto this.As has been said, the main issue with these heaters is once the heating loop is up to temperature, then the unit will shut down.
Power up / down pulls apx. 17 amps so if allowed to repeat through the day your battery will suffer.
This is the unit burning off any excess fuel in the ignition chamber.
Main concern is to prevent this.
I built my own system (9kwwebchinasto) I use a third heat exchanger (HE) to bleed heat into the tank once the loop is hitting 85°c, so stops this cycle.
I also fitted an EGR cooler from a Jaguar on the exhaust. Before fitting exhaust was 300°c +
After fitting, 70°c
Tank water is circulated through the EGR
I've had no issues with the heater, but have to run the coolant loop heat higher as the heat exchangers are slightly undersized (due space restrictions and my inexperience with calculating temperature exchange deltas)
Another reason for high temp is that the header tank is only 5 liters which is the biggest I can get that is made from polypropylene which can take 120°c
All the header tanks I see on xline, pure freedom etc. use a tank manufactured by kingfisher (polyethylene) which can take 60°c.
I Have seen these melt if the heater loop is turned up too much.
Another (simpler way) to bleed heat back to tank is a simple solenoid valve between the HE & hose reel. But the pump on this line must be switched on.
My third heat exchanger is a 22kw unit. Works fine. I also have the pump on a 12v PWM regulator. The pump speed is set so the pump pushes just enough hot water to lower the temp slowly.As has been said, the main issue with these heaters is once the heating loop is up to temperature, then the unit will shut down.
