My Hubby just installed the new RV-550 EC tankless water heater, We love this so much already and we will probably be purchasing another for our tiny house that we will be building soon !
Nothing like a 15 minute shower after a long day or even just to wake up. Try that with a regular RV hot water heater and you will be freezing!
5 Stars isn't enough !
I own a 2018 Forest River Wolf Pup camper the my Wife & I live in full time and it had a 6 gallon hot water heater in it, I was tired of turning the shower head on and off to conserve hot water while taking my shower, honestly this tankless is the best investment you can make for your camper!
Installing the tankless is simple and common sense 2 wires for 12 volt positive and negative, That's it for that, then connect the hot and cold lines and finally the propane line. 1 1/2 hours later I was taken an uninterrupted hot shower!
Yes I recommend this, oh and don't forget to order the buytal tape and door for your full installation..
With the standard 6 gallon water heater, my Wife could take her shower but it had to be taken fast or you would run out of hot water, Then I had to wait for the water to heat up again for my chance.
The Precision Temp RV=550 EC is the greatest thing ever !
GOOD TIMES HAVE COME OUR WAY !
Thanks Precision Temp !
Precision Temp is an extremely dependable unit. I have had my RV-550 for over 4 years now. I live in my RV Full Time with my wife and daughter and believe me we have used this hot water unit countless hours with very little problems. Gary in technical support is fantastic to deal with for any troubleshooting you may inquire. I am a Steamfitter with over 40 years over experience, and I can tell you with confidence this is a great unit for the price!! I’m a happy camper!!!
We purchased our first Motorhome after several 5th wheel rvs. All 5th wheels had hot water heater tanks and motorhome has the tankless on demand rv-550 unit. We use every other month and had issue with no hot water on our last trip. Called Precision Temp service and left message----they called within 30 minutes and suggested several things to try. Within an hour, water heater was back up and running. By the way, you can shower all day if needed!!!! Can't say enough about these folks! Thanks Gary for the help!
I had owned previously in my 27-foot RV Carriage compass the model 550 tankless hot water heater. I fell in love with it never had an issue always the correct temperature. Right now I purchased a new RV it's a keystone Alpine 36 footer and it has a 12 gallon hot water tank and when my funds allow it I intend on changing that 12 gallon hot water tank to the model 550 tankless hot water heater I will be having my local RV maintenance guys take care of it for me this is one hot water heater that hands down beats all that I've seen.
The PrecisionTemp RV-550 EC tankless, water heater utilizes our patented VariFlame Control technology to deliver an endless flow of hot water for the ultimate shower.
Whether in the dead of winter in the North Dakota oil fields or on sunny days in southern Florida, hot water is there for your enjoyment.
With 55,000 BTUs—the highest hot water output in the industry—and built-in freeze protection, the RV-550 EC delivers on-demand, continuous hot water.
The heater operates only when the hot water outlet is turned on. The VariFlame control system then keeps the water temperature constant, regardless of the flow rate or incoming water temperature.
With higher efficiency and 55,000 BTUs, the RV-550 EC produces more hot water than traditional water heaters.
Without a tank to keep hot, many people report that they use up to 50% less propane. Owners love the lower operating costs and fewer fill-ups.

What makes the RV-550 special?
Continuous, endless, no-wait hot water for as long as you want. You can shower for an hour! Or longer…
How does the RV-550 provide continuous hot water?
The RV-550 has no tank. The water is heated as it flows through the copper tubing.
How do I get the RV-550 to make hot water?
Simply turn on a hot water faucet. A flow meter in the RV-550 is activated and the heater automatically comes on. When you turn off the faucet, the burner shuts down. There’s not even a pilot light — it uses a 12V current for the electronic ignition.
How long does it take to make hot water?
The RV-550 begins making hot water in seconds.
If endless hot water is such a good idea, why doesn’t everyone do it?
Most people don’t realize that they have an alternative to tank heaters. Once you use one, you will never want to use anything else!
Does the RV-550 install just like other water heaters?
Yes. The RV-550 installs and flues just like a tank heater. The RV-550 NSP installs just like a tank heater, but flues through the floor instead of the wall, using the included exhaust pipe. The water, gas and electrical hookups are the same type used on tank heaters.
Will the RV-550 fit into the same hole from my old water heater?
In almost all instances it will. The RV-550 is designed to replace most 10 gallon heaters without modifications. Cutout dimensions are 14.5″ high x 13.5″ wide x 13.5″ deep. Flanges are 17″ high x 17-5/8″ wide. To replace a six gallon heater, add 2.5” in height (up or down) to the sidewall cutout.
How long are the venting pipe(s) supplied?
The standard exhaust pipe is designed to go through a typical 1.5″ floor and elbow to the side, but we can provide the extension to go through a thicker floor, or you can get one at a local muffler shop. A PVC conduit can be used through your floor for combustion air.
Is the RV-550 as noisy as my current tank heater?
No. It is so quiet that the only way you know it is operating is that you have hot water!
When operating, does it create as hot an exhaust as my tank heater?
No. It is about 50% cooler. It will not scorch the side of your home.
Does the RV-550 use more propane than tank heaters?
To the contrary, the RV-550 is far more efficient. Plus, because there is no standby heat loss, you may find that you are using only half as much propane.
How do I winterize the RV-550?
Simply drain the RV-550 of water by blowing it out with air or running non-toxic antifreeze through the heater while winterizing the rest of your plumbing system. The RV-550 only requires about a pint of antifreeze.
Could you further describe the cold weather protection system on the RV-550 model?
The cold weather protection on the 550 series is standard. This feature will prevent freezing under most conditions. It has a built-in thermostat that turns the burner on in low burn when the heat exchanger temperature is about 38° F. At the same time, small 12 volt heaters protect the internal plumbing and control valve.
In order for this to function, the 12 VOLT AND GAS SUPPLY MUST REMAIN TURNED ON. This allows the burner to fire and electric elements to protect the system. Any freezing of the water heater or other plumbing components can cause severe damage that is not covered by warranty.
Unlike other tankless models, you don’t have to dump water on the ground or plumb it back into your water tank. This wastes water and propane. Our freeze protection uses very little propane and less than 2 amps of power.
Aren’t all “wetted” components in the heated living space of my home? Why do I need freeze protection?
The “wetted” components are technically inside, but the combustion air is drawn from the outside through an opening in the bottom of the unit. On the NSP model, the 2″ exhaust pipe also goes to the outside. This can allow freezing air to enter the unit.
