Hi Lloyd, Is the filter the same as the ones on washing machine hoses? Cheers

I dont think your filter idea is the best way of filtering the water to your HWS. A far better method is to use an inline filter that you can buy from garden supply outlets. Its about 150mm long and 25mm in diameter. You can unscrew either end and remove the filter inside to clean and replace. Each end has the normal garden hose type coupling. Put the filter anywhere between your pump and HWS. The best thing with this type filter is that you can easily clean and get underway in a few minutes. If I can find a photo I will post it here.

I have to disagree about the inline filter. They can block up. Mine did and i got burnt. Myself and a few other dredges use this simple washer filter. (Yes, its the same as the ones for washing machines) and its never blocked. It can't block up. I've been burn't before and there is no way i'd use anything but this type of filter. i hope these photo's come through. notice that nothing is clamped after the tap and that i simply use a short length of coper pipe to connect the hose that goes into my suit to the hotwater hose.

this is where the filter goes. i might have to try getting a photo inside the pump to show how it ever so slightly protrudes into the flow of the water in the pump Attachments:

Thanks lloyd. i like the fact that the water is either forced through that washer filter or the crap is blown off the mesh to allow water through . At first i thought the inline filter was a good idea because it has more surface area of mesh, but it could still block up if the water is dirty . I also like the idea of the thermostatic mixing valve on Rods heater aswell but would it be wrong to put some pressure relief in there before the mixer because if the valve senses a temperature spike it will shut off the steam/hotwater then where will it go ? I have heard that the mixers can fail when they encounter extreme temperatures .

I'm not sure, i have no experince with relief valves etc but i think someone commented on having a reserve of water in your line, is a good idea. It would have to be after the tap and not be too large as to cool the water to much i'm guessing. Hmmmm, the inlet to the reserve if i'm thinking right would be at the top of tank and the outlet at the bottom !!! someone correct me if i'm wrong. Anyway i'll just add one more photo of the tap and notice i havn't clamped the line to it. The last comment i want to make is that i went a little overboard on the amount of copper pipe i used but i did that on purpose so i can pretty much keep the tap nearly fully open. Attachments:

Hi You may already have been told or already know that its a good idea to have a join close to you in the hose so you can pull them apart as soon as you feel the water temp going up but its also a good idea for the last part that going into your suit to be a soft hose so you can fold it to cut off the flow while you try to pull the two hoses apart. Also if the rose is between your bottoms and you over jacket the water will still heat your body but not your legs this is not as efficient but much safer. Quack

This hot water thread has been a good one, my surprise is the number of people that have encountered others issues and or been cooked by there system. I looked at a number of systems and am a but doubtful of setting one up running of the motors, So I have tried a califont, yes they switch of at 20 minutes of use. It was a a thing to try and I set it up and worked it for an hour or two. unfortunately I have become unwell. Hospital for 4 weeks and at home bored. So did not get a chance to put it to some real work. The only modification is it needs a filter and have taken on board what has been said. I do have a tap at the pump and a tap at the weight belt. also a soft pipe into the wetsuit which is very easy to pull out. Its attached to the airline and floats.
The califont I used was a 5 litre per minute model. I set it up and it could heat 11 c to 74 c you could not put your hand under it , realize its not a big flow. with adjusting the califont I got it supplying 42 c water. I was told that they would only heat about 25 c above the input water temp, believe me that is not true with the small califonts. (what would be a good Temp? some have said just over body temp? ) When they say I am allowed back on the road etc. I will be trying it out properly.
With the tap I just switch it off and on every ten or twenty minutes when I take a break and check my lines and weight belts. The califont switches off then back on and straight back to the set 42 C temp. With the tap up topside the person up there can switch it on and off the same way and you would not know its been done. It uses 2 size D batteries to run. When I have the dredge all back home I will set up and take some pictures if people would like. a friend has tried a bigger califont and they do not work as its all to with water flow and they need to much.
Only thing I don't like is when it starts it tells you the water temp.
anyway my dredging season stopped real quick ANZAC day or the system would be well tested. Cheers

Hi I was one of the three on the trip where Hutch got the bad burn although I was working on another hole further up stream at the time. After reading this thread I think we all should be looking at the best way to be prepared if a burn dose happen one of your team. I have just a start on things we would do now with the help of (captain hindsight) (1) Have burns first aid kit. (2) Be aware of the closes land line i.e. local framer. (3) Try to keep the victim in the water as Long as possible (4) Don't leave him to go for help he may go into shock and drown. This is only the start so if there is a doctor among us he may wont to add or change my short list. That it from me. PS Get your name on there will. Quack.
