Hi, yes it was me that got burnt, and I wouldn't wish it on anyone. Its now been 3 months and the scars and discomfort are still well and truly there. The surgeon has said it will take 6-12 months to heal. After much thought the only reason for this accident was that the small clear hose that I placed in my wetsuit was too long...the water hose was the same as the air hose, the non kink type. We had filters on which we checked and cleaned regularly, the connection between the water hose and the clear hose into the suit was a click on fitting which requires both hands to unclip it....this is not as easy as it sounds when you,ve got boiling water going into your wetsuit. before my mate got to the machine to turn it off I think I could feel cooling water coming through, this explains that I must have rolled a rock onto the small clear hose stopping the flow and heating up what was in the heat exchanger and when I stood up and pulled the hose it released that water into my wetsuit. Im guessing it was probably only about half a litre or so of hot water but it was enough. I am looking forward to getting back into the water but may use a drysuit next time. I appreciate everyones comments and ideas on these systems, a lot of you have said that a filter is a must...I do agree but it didn't save me, I think a combination of things are needed i.e.. filter, surge tank , keep a regular check on the foot valve and clear away any leaves etc, a non kink hose to a valve or connection that dosent need 2 hands to operate it and is secured in a fixed position so that you don't need to look for it when the **** hits the fan, and that the clear hose into your suit isn't any longer than your upper thigh. Rock on next season.

I've decided to take a rest this week, gather my thoughts on how to proceed. Need to sort my living conditions at home to. living in squalar. Keep us posted on the proline hose, what size are you useing? I'm going back to Barfellm i think, Good stuff, I'm not sure wether you NZ guys have ay experience with it but its Quite flexible and light and these days its durable. Its basically plastic and hard inner surface, almost has a waxy feel to it so it rarely gets blockages. Its only downfall is that its not see through and the new stuff is black so even if you lift it out its hard to see where they are. Good stuff all the same.

i just notice drg post of the tempering valve. www.apexvalves.co.nz/plumbing/apex/tempering.htmlI try to keep my stuff as simple as possible and don't add stuff unless i fully understand it, also want to keep it as simple as possible. This little valve looks simple as. From what i can make out, it lets the warm water flow but if for some reason it heats up to much, it opens the inlet for cold water right ? So long as the cold water hasn't had its flow stopped its all good.

having read all this, and considering that my claim has good access, think I will simply use a gas califont, at least they switch off when the flow stops.

Solution will be a secondary heat exchanger between the hot water and a separate line to feed the divers so no steam can be inyected.

Hi There, I am currently reviewing the possibility of going full time dredging sometime in the future and hence researching Hot water Systems which will alllow 8hours dredging in cold Otago shoulder season waters. I have briefed most comments and would like to thank everyone as they have been very helpful! Just a quick question of Safety, - why not incorporate a Thermostatic Mixing Valve set to say 35 degrees with an automatic shut off when the temperature gets above say 38degrees? www.hotwatercylinders.nz/images/source/RMC/HEAT160035-1.jpgI have yet to research these valves and there may be an ovbvious reason they won't work but seems like a logical solution if they do? Cheers
