I suggest you ask Oliver regarding safe operating.temperatures.

There are so many variables that you need to be aware of if you want to avoid buying new glass for your customers.

First of all, the hot water didn't cause the glass to break. It also seem to contradict the Mpemba effect where hot water appears to freeze quicker than cold water.

on a really cold day i thaw out windows that are frozen(on connys/porches with no heating on)with my hot water no problem...they dont ice back up either usually so hot water DOES NOT freeze quicker than cold water at all......its a myth.....(for cleaning windows in icy conditions anyway)....

You will love it.

I have two pumps running..   Mine can't run one hot and one cold.  They need to be the same. The heater is controlled by one controller to turn the heater on and off.    The second pump and controller draws off the boiler whether its on or off.   So if the Heater is on then both pumps run on hot.   

I keep the second pump running back to the tank at a low flow just to prevent the burner shutting down when your main pump is DE.    Don't worry as it takes a while anyway to shut down if you don't have another pump on constant flow back to tank.   But if you leave your main controlled on DE  for more than 5 mins without a second pump running the burner will go into shut down mode. 

It's advised not to keep it going into shutdown mode and startup mode regularly. 

Use the return to tank method to keep burner on between jobs if its going to be less then 20 mins between the jobs to help protect the burner.

Thanks Paul!

I’m going to run it the same way. If there’s two of us working then great, if not I will have one circulating back to the tank and monitor the temperature of the tank water.

[Jonny 87]

jonny you live in scotland.....is there a fitting centre up there or are you coming all the way down to cambridgeshire?

There is but I’m coming down to Cambridge for it.

Fitting is actually a few hundred quid cheaper, and I quite fancy making a trip of it. Wife is already planning places to visit when we’re down, lol.

I’m just ironing out the final Details with Oliver, then going to get a date booked. They are booked out till November though. Just hope this winter doesn’t start too early. 😬

[Splash & dash]

I have a Grippatank 9 kw boiler with two heat exchangers one runs each hose reel we work as a two man operation per van. in the summer I have it set on minimum as it was so hot you couldn’t put your hand under  it at all or re wind the hose you couldn’t hold the hose , winter time it’s run flat out all the time on maximum 8 hours a day 5 days a week I find that my fuel costs are around £70 per week and we don’t do much mileage it definitely uses more fuel than the manufacturer s figures , but I would never go back to cold it’s definitely quicker , cleans better , especially on salt covered windows , and plastic cleans , we have cracked 2 windows in four years not good but u can live with the occasional pay out both windows had previously been damaged or were packed to tight when originally fitted ,according to the company who replaced them ,

If you run very hot if any pane has a tiny crack in it on a cold day it will crack from corner to corner as soon as the hot water hits the glass,a lot of the time these small cracks can’t be seen from the ground. I clean with confidence on PVC on very cold days but you have to be careful on older glass. 

[dazmond]

I cracked one small pane on an opener back in Jan.it already had a small crack in the corner and it went the full length of the glass and popped!the customer was fine about it as it was already damaged....my water was warm(not hot).It was quite a cold day but not freezing(4c)...

I'm now very careful of any glass that has a crack in it as hot water will damage it even further....

[dazmond]

For those who 've had the hydroheats for a while...have you ever had them serviced and where do you go?don't fancy going all the way back down to Cambridge if I can go to somewhere nearer...pure freedom said they would service it for me when the time comes(it's a bit nearer than cambridge)

Cheers lads

[NWH]

They’ll service it at your house I don’t rhink there’s a lot you can do with em tbh,if something’s not working on it you’ll know very quickly. You have the plug in battery converter with is key to keeping them running right I do 60 odd miles a day which means I only need to plug in the mains once a month or so as I have there very good split charger also.

have you ever had the burner replaced on your 10+ year old heater nigel?or had anything replaced on it during its working life?

cheers

[NWH]

I replaced everything on it Daz I changed the complete unit,when you assemble the new 1 you have to put it together like your changing a burner. You have to reinsert the burner line up the glow pin and plug the burner or glow pin lead back into the unit,it’s not to bad to do quiet easy really you just have to make sure you take pictures with all in place and keep taking them as you take it apart.

[NWH]

If I had to change a burner it would be no problem probably take an or so,taking it apart and putting it back together is what takes the time not fitting the burner.

[DeLuce]

Those of you with a Grippa system, how often do you charge it over night?

I charge mine every weekend for one night !!
But my round is quite scattered. I don’t have houses together where I would be there cleaning for a morning or all afternoon like Daz. So the system gets a charge up between customers.

October 31st & November 1st. 

Booked in for the 9kw hydroheat, battery to battery charger, new hot water hoses and fitting.  Can’t wait.

[The Jester of Wibbly]

Nice.

Just do your research on the chargeing method as its unlikely a battery to battery charger will cut it.  You will also need to bench charge from time to time. 

Grippa installed one of me so all I do is plug  the mains into the socket installed on the van and let it charge overnight securely.  It also needs to be a powerful one to be able to charge two batteries..

You might want to think about this before purchasing both options.   The bench charge will be enough without the need of Battery to Battery instalation.

Thanks for the tips paul. That’s an interesting one. Think Im Going to stick with the battery to battery charger and just monitor things from there.  I don’t mind having to bench charge every other night, or even every night if I have to. I also run two power up reels so I think I need to have some power getting put back into the batteries throughout the day.

i disagree...i think its better to have both charging methods to keep the batteries in tip top condition...diesel heaters are heavy on  batteries esp the 9kw version so i little charge when driving to and from jobs and driving to work and back keeps them from dropping too low IMO.....

[The Jester of Wibbly]

Probably overkill Daz or paranoia 

Been running mine a year now bench charging every night.  Battery readings never go under 12.4 at end of day.  Most days it finishes on 12.5.

However I don't use power reels though.

both me and jonny use powered reels so that takes more out of the batteries each day......id rather not discharge them more than 25%(its supposed to be better for the batteries longevity).....also occasionally ill go 2 days without bench charging....

[DeLuce]

I'd get both in the van too.
That's what I've got, the 9kw plus electric Grippa reel,with batt  to batt charger as I drive around, and also the smart charger for a boost at the weekend (for me anyway, as I don't have a really compact round). Grippatank put the plug socket at the back tailgate of van and provided the right length extension cable with plug for my shed socket. 
Well worth doing that Jonny.
I liked my immersion set up.
 But there's something about my Grippa set up that makes life so much easier. Most days, I just get home, fill up the tank. That's it. On the weekend, one night, I'll put the charger to go.

Sounds great. I love the idea of never having to worry about heating the van at nights during the winter too. Was always a pain for me trying to work out what setting to have the oil filled radiator on, and even then it didn’t always work. Plus cost me a few quid at night just for protection.  It’s a luxury I’m really looking forward to.
