With constant circulation it’s more  efficient  & cost effective to feed into a header tank rather that the main water tank. If you main tank feeds a much smaller header tank (with a ball valve) and this header tank feeds the pump, when the water returns back into the header tank after going through the heater it will preheat much quicker.

As it enter the heater at a higher temp you use less gas /diesel to bring it up to working  temperature. Also you are not  unnecessarily heating up your full main water tank.

I don’t think this option is available from hot WFP manufactures but it’s used by other industry who clean with hot water so anyone doing a self build it might be useful to incorporate such a system

The heater has an internal flexi hose I changed this for the same with a flat blade screw,if you shut this off it gets hotter than standard heaters as no cold water passes through it I’ve been doing it in summer for years. Not recommended if it’s under warranty though.

today i timed myself.apart from 30 mins for lunch and a 10 min coffee break this afternoon my intervals in between jobs/windows with my pole tap off was no longer then 3 mins(mostly 2 mins).usually it was to move my hose or trad the odd ground floor windows.

is this a short enough interval to keep the heater from going into "shutting down" mode?

Hi Daz.

I think we are going to have play it one day at a time.  Just get used to the equipment and see how it handles downtime. Then adapt your methods of use to your needs.

My guess would be that it will shut down have a good chat to Oliver explain what you are trying to accomplish and he will be able to modify it to suite your style of work to a degree that’s what he did with mine anyway,

Probably will keep a box of tea bags and a mug in the van.  TEA ON TAP.

that means the heater will be firing up and shutting down many times over a day which is supposed to be bad for the burners(as well as fluctuating water temperature).i was hoping it would just keep running.it doesnt sound like these heaters are suitable for wfp really.

still time to cancel your order, personally i would have asked all these questions first  . I dont know why you just dont rig up filling your DI with hot water from home, you've said yourself hot doesn't make you quicker or is that necessary. If its supple hoses in winter you want then hot straight to DI will do the job and save you over 4k.

Have a chat with Oliver like I did yesterday following reflections posts.   That's why I'm now going to run my other pump all the time on a trickle.   I don't think it will cost much more to run it this way.

He did say the system will go into a standby mode of some kind when it comes to temperature without turning off for a short period of time.  So you will have to see how it works for you. 

He also said the system is intelligent and designed to switch on and off at times.  But not to do it too many times when working compact.  It does not damage the heater but will shorten the life of a service before getting in cleaned out.

As you say.  Your time between jobs is very short so you probably won't have it running that much longer than you would working on the glass.

You have a small tank like me so come the afternoon when your tank is less than half full you may get away with turning the burner off as your tank water should be warm.

It will be fine just have two heat exchangers and one of them returning water to the tank all the time and the boiler will stay on all the time this is what we do and never have a problem , you are stressing yourself unnessaseraly Oliver is no fool talk to him and he will give you options as to the best way to do it for your situation

Sound advice it will be fine we have a 1000 ltr system and when I work on my own after lunch I still have about 5-600 ltr in the tank it’s that hot you cannot put your hand in it , if you want to you could turn the boiler off and use it that way we do that in the summer months , with a 500 ltr tank it will heat up much quicker as you will have half the water I do , Oliver is the expert but if you want to give me a ring Ime more than happy to talk you through what we do it’s difficult to put it all in writing on hear

[Jonny 87]

Daz id definitely have a chat to Oliver before next week.

As above, a hassle free option for you would be to get a second pump fitted to circle the hot water back to your tank, then by lunch time you can jusy turn the burner off.

I’ve been looking up a lot on the webasto heaters over us last few days, and this seems to be the best and most efficient way. It would also tie in with why I had so many issues all
Those years ago with the webasto heater, ours was constantly stop Starting and then every 4 months or so the burner would die, meaning a £300 bill. The technology has probably improved inside them too mind you.

It’s worth while having the chat though. 👍

Thanks for all your advice buddy. It helped me big time to get my head around the procedures.  Oliver also put my mind to rest last night too.

Daz. You will be fine mate

[NWH]

Daz you are having the plug in overnight option which I’m having if you charge on the mains every other night your heater will run fine but you will need to do this,if you stop for lunch and you have a bit of a drive to the next lot of work it’ll be fine if it powers down once or twice,as a rule if you want hot water between jobs just recirculate it back to tank it’ll keep the heater working turn the flow down the lower the flow back to tank the hotter the header tank will be.

[johnwillan]

Hi Dazmond
Spuce's reply (No 63) explains perfectly how the Grippa system works, as stated it will not shut down each time you stop the flow.

As explained we run these units and they are great, recirculating on route, between cleans or during breaks does raise the temperature but it's not imperative, I'd say it's more a personal choice.

I suggest you wait and see, I'm sure you won't be disappointed.

On what are you basing this ? It will shut down in a short space of time if the flow is stoped , this is why the return to tank is put there to prevent it shutting down and keeping the water in the hose reel cerculating so is stays hot

[NWH]

Above is correct I’ve had 1 for 12 years if you don’t recirculate back to tank it will after a short while go into shut down mode,as for servicing these things a year  or 3 yearly service is rubbish you’ll know if the burner or the heat exchanger needs replacing because it won’t heat the water as hot. I changed my burner after 11 years and at the time it was still working my main issues with heat was battery power.

At last someone who knows what they are talking about , to many people voicing opinions on something they have no experience with and giving out confusing and wrong information to people considering buying these systems

[dazmond]

cheers lads.ill make sure they fit a recirculate back to tank on the system when i take it in next wed morning.

IMO if the burners on these heaters soot up and fail prematurely due to constant stopping and starting(firing up and shutting down)then they should fit a recirculate feature on them as standard.shouldnt they?

so to get the best out of these heaters is to keep them running constantly for most of your working day with minimum shut downs/start ups?

[dazmond]

im surprised theres no videos showing how these heaters work
