Propane preheat

[Ryan]

Is there any reason I shouldn't preheat with something like this? If I set it at 130 or so my pump should be able to handle the heat fine.

What's the flow rate? Heat rise over incoming water? Nice small BTU's...

This ones most likely a better choice. 45 degree rise @ 2.7 gpm. I'm at about 1.8 gpm coming from my wand and it is only triggered 50% of the time so it should give a nice rise in temp.

I gues my real question is will this hurt a heat exchange TM? I'm curious if it will cause it too overheat or anything.

Good question. I'll plead the Marty.

LOL I think I'm going to try it. I might ditch it this summer but my heat isn't crap in this freezing weather.

i preheat my water in my v and run it through my traditional exhaust hx it shouldnt hurt anything but i would probably talk to greenie if you dont have a diverter or a bypass on the hx.

Do you use a water tank or hook up directly to a hose?

 

[Ryan]

I have a 55 gal tank but I think I'm going to set this up to run off a water hose.

I had a tankless at my last house. It will need to sense a certain flow before it kicks in, might want to verify the exact specs. Will the water go to a mix tank or direct to the pump?

 

[Ryan]

Its made for camping so a water hose should have enough flow to kick it in. I'll ask the seller about it though thanks for bringing that to my attention. I bypassed my mix tank because the float valve kept going out and I was sick of replacing it. I have a chemical draw (pressure washer style I think its called a demi valve) setup after my pump.

I ASSume your float valve was electric? I used one of these to replace my electric float valve.
