RVing In Winter Water Pump Freezing Solved

[@etubrutus3501]

Good job, I love your innovative solutions. To those who are afraid of the electrical component, insulating the compartment and installing a lower and upper vent should achieve the same result. Perhaps not as efficiently, but the idea is to keep it above freezing, not warm.

That's a great idea! I hate to rub it in but where I live right now it is 76 degrees out. Stay warm!

On Amazon you can find DC ventilation fan systems and vent grills used in audio/video and IT cabinets. These are scalable and thermostat control is available for these units. This gives you a greater selection of computer size fans moving as much volume of air as desired..

I searched your key words and did not find many options. I recieved more results just searching ps fans or 80mm fans. I could add a potentiometer to controll fan speed but the arctic fans I chose are whisper quiet at full power and move plenty of air. If you have a link to better fans I may share the link in the description. I picked up five fans for 15 bucks but then the price changed to 24 bucks. Still not bad. I'm sure people are open to suggestions. Let me know. Thanks and take care. Jim

You should only need the fan on the exhaust side and just a vent on the intake.

It is a big cabinet for one 80mm fan. I did try it with one fan and it was not circulating enough for me. Feel free to experiment with you setup. Thanks for the comment and happy camping. Jim

HaHa 15 degrees made me laugh..you see I llive in Alaska and 15 degrees to us is very warm out. :)

This looks like a great solution.

Sweet

Have you considered insulating the walls (&floor) of the cabinets

[@ptcclatlptcclatl1683]

Jim, you couldn't run a heat duct into that area with an exhaust vent? On second thought all you need is the exhaust fans with small vents to draw warm air in. That way you would only draw half the power.

[@fullmoonadventureclub]

Unfortunately, there is not a single heat vent on that side of my RV. It was easier to run wiring than duct work. Otherwise it would have worked to have the duct work run through the cabinet which would give off enough heat to keep the water pump warm. Good idea though. Thanks for the comment and happy camping.

Great innovation solution to the freezing fresh water tank and hot water pump ... However you went too fast in how to wire the whole system... can you comment on that ? much thanks... AT

Super! :)

Great idea. You might want to try just running the two lower exhaust fans and save a bit of power when you keep the inside temps well above freezing - they might provide enough circulation. Another potential modification is to use a 12V thermostat like this (Amazon ID B01H6FBY92). I've seen people use 120V thermostats to cycle power to deep freezers (the kind you reach down into) to operate a chest freezer as a refrigerator keeping food around 35 degrees.

I thought about doing both of those things. Running two fans didn't quite get me up to RV temperature. I also considered a thermostat but at .8 amps I'm not too worried about it as I rarely go camping in under freezing conditions. But when I do it'll work. I should have mentioned that in the video but since I didn't do it in my install I just left it out. Great ideas though. Thanks for sharing them with us. Take care and happy camping. Jim
