Also, if you stop the water flow for too long the heater will shut down.

Agree, But it doesn't matter how you stop the water flow. Stopping it for too long will cause the boiler to shut down, which is when our problems start. It takes power to restart the boiler which can deplete battery charge and if it's a regular occurrence, sooting up of the boiler internals.

That’s a potential issue for me as I don’t do many houses in a row. So it would be start/stop a lot. My round is bigger houses spread over a a square mile at times.

You don’t want to be turning the boiler on and off it needs to run all the time and have a return to the tank so it keeps running  otherwise you will have no end of problems a diesel heater isn’t like a gas boiler with on demand heating , also if you turn it off the hose reels will go cold , ours run 8 hours a day and don’t switch off apart from lunch times .

One of you needs to upload a video to YouTube, showing how it all works etc etc. please

I would imagine the easiest solution (although not cheap) is to have a two man system with one on tick over sending hot water back to the tank.

As I've mentioned before, I've modified my 2-man system by adding a third heat exchanger. I've added a 3rd Shurflo pump, pwm controller and a 12v digital temperature cooler. When the internal circuit's water temperature reaches 82 degrees C, the digital controller activates the 3rd Shurflo pump bleeds the temperature back to 76 Degrees C. At the point the pump switches off. Between those temperatures the Webasto pump is on tick over and this allows my heater to run for hours without it switching off and restarting.

I just connect my microbore to a female EZ in the top of the tank I’ve fitted,after every job I can connect it’ll never turn off.

Hi Zesty.

The WFP Link radio remote controllers and the Stand alone radio remote controllers are controlling the delivery pump out to the reel and giving the flexibility to adjust Flow and Pause flow. We have produced V16 HW controllers that can switch a Heater and have frost protection. Many of the distributors use these when making a Hot water system.  Pausing the delivery  pump does'nt stop the heater. Most hot Boxes have a header tank and the heater has its own pump to circulate water through the heater and header tank and exchange plates as Spruce has commented.

The Controller is switching the Heater via signal cable (purple) https://www.youtube.com/@springeuropeltd7880/videos

When we could get Bluetooth modules just before the world went mad we  have made V16 WFPL HW and via the app the heater can be switched separately form pausing the pump.  (Currently we would make V16 WFPL HW XBT (no bluetooth) if ordered)

As long as i have not miss understood. If you bought a Hot box that already has a V16 HW, You can add the One Shot stand alone as now between the HW controller and pump on the Brown cable.  Or If you have a Controoler with WFPL you could  as some choose to just leave your existing controller to manage the delivery pump and have the V16 HW in the Hot box to just switch the heater, use frost protect and monitor temperature.

Cheers

Spruce, where have you been? There’s loads of threads that need adult replies on here instead of the forum clown!

I struggle to keep up these days. The wife slipped when exiting a narrow boat on a one day cruise in Skepton in July and broke her hip. They operated and pinned (screwed) it together in Airedale hospital. This has failed and she is on the waiting list for a full hip replacement. So this means that I get the caring duties, the shopping duties and everything else hospital and doctor related because she can't do much and she can't drive like this.

Lots of things have taken a back seat and tbh, I'm just very tired.

Sorry.

I am very sorry to hear that your wife is a lot of pain. I hope that she gets the replacement she needs and is soon getting better again. Best wishes to you both and take care

Thanks Ian, that’s very helpful as always!

The last paragraph is probably the way I will go.

Thank you guys for best wishes for the wife's speedy recovery.
She is feeling pretty low ATM.

Being on a morphine solution i for pain isn't helping her mentally either.

She has had one op cancelled at the last minute and now it's pencilled in for the end of February 2023. So she has a way to go before things improve.

It's a longer op than just a replacement hip as they have to remove the existing metal work and make that good first and then start on the hip replacement.

Hope all goes well spruce is there any chance of getting it done earlier with a cancellation spot ?.

I’m afraid the NHS is totally broken spruce, and that’s coming from someone who’s wife works there.

It needs reform, it it simply unexceptable that she has to wait that long. I hope it gets brought forward. A tough time, but you will get through it.

You're right, zesty.

Best wishes to you and your wife, Spruce. It's an awful situation for you both but at least your wife has you to look out for her.
Take care and keep posting if you can, my friend.
