jleamont Report post Posted May 9, 2018 Had enough of our Aquahot and it’s only able to provide CONTINUOUS how water in the shower for maybe 15 minutes. I went all out and installed a Precision Temp RV550NSP tankless and plumbed it to the shower hot side. Link; https://precisiontemp.com/products/rv-550-nsp/ Problem with Aquahot (especially older models) they only can provide 55 degrees of water temperature rise, when your water coming in is 37 (37+55= 92 aka mad DW ). I have never had a cooler shower as I don’t take that much time, her...well not so lucky. The Aquahot will come on strong but it’s not a direct fired water heater, said another way the water coil picks up heat from being wrapped around a boiler that is hot. It also doesn’t turn on when water flows which gives it an opportunity to cool down and recovery just isn’t fast enough. A true tankless water heater come on immediately when water flows through it. This unit provides 88 degrees continuous. I just wrapped up the Exhaust final touches. I ran it a few weeks ago on a test and the shower never dropped below 125 degrees for 45 minutes. Here’s some photos; I changed the tips to match both heater systems. Share this post Link to post Share on other sites

Bill Yeah, if I got my tail handed to me one more time for that water temperature issue this coach would have been up for sale and I might have been part of the package deal .

manholt Report post Posted May 10, 2018 Quote Looks good. Is that "bondo" on the lower bay door? Hard for me to relate to cold shower, never had that problem with my AH. Linda will take a shower, then me and there is no cold spots or decrease in temp! We do not require "boiling" water! My mother was a Dermatologist, "too hot water, over 104 degrees, is not healthy"! Hot water, is like a steam bath, it opens the pores, then once clean, you want to close the pores, by taking a cool shower! That consultation is free of charge, since I don't have a License!

jleamont Report post Posted May 10, 2018 Jim, https://vibrantperformance.com/catalog/index.php?cPath=1527_1034_1056 Carl, that is a reflection of the exhaust hanger box and a sheet of cardboard I was laying on, the paint on this coach is like a mirror. Make sure you tell her that when you meet her in a few weeks, give me a warning first, so I can start to sprint away Share this post Link to post Share on other sites

hermanmullins Report post Posted May 10, 2018 Joe, I didn't see it anywhere, is your Tankless WH diesel or propane? Herman Share this post Link to post Share on other sites
jleamont Report post Posted May 10, 2018 Five, unit was $1125 to my door, extension pipe for the exhaust, clamps, hangers, PEX tubing and elbows, propane hose, (20 gallon LPG grill tank already had extras), TWO propane tank holders DOT approved with strapping, (I carry an extra 20 gallons of propane) stainless exhaust outlet. Total out of pocket $1240.00 The project took me about 4 hours from start to finish. The hardest part was drilling the air inlet and exhaust holes in the floor, trying to miss the cross beams on a Semi Monocoque chassis was a bit challenging and utilizing the space so our junk would fit back in Share this post Link to post Share on other sites

jleamont Report post Posted May 10, 2018 5 minutes ago, hermanmullins said: Thanks, Cold water has a "T" just before the Aquahot, that line comes up and over into the tankless unit as the "blue" line in the photo. They are all routed for full access to the Aquahot for routine maintenance, No obstructions! The red out goes right back into the bay and is connected to the shower hot line which is removed from the manifold and connected with a Shark bite. If something goes wrong I can release the shark bite, reconnect the line to the Hot water manifold and open the valve and its back to the factory design. I actually considered pulling ball valves in to redirect the water flow, but I figured that would be over engineering. I ran their wall mounted tankless water heater from this company (same internal specs) in the last coach for 6 years, never had a problem other than couldn't get my DW out of the shower.

I was running it for the first time, DW comes out "well i see you got it working" how do you know that?
