Who can we get service information from? Tiny House who we purchased it from hasn’t responded. Only had the water heater a few months and haven’t used it again til now. Very frustrating!
Please call Ray at 513-641-4446 ext.110. Ray will be happy to assist you with your PrecisionTemp on demand water heater.Thank you for reaching out to us. We want to have happy customers.
The folks at Precision Temp are a great group of folks to deal with. The Techs have saved my bacon a couple of time with their Informative Tongues to my Attentive Ear(s). For that I am very thankful and blessed.
The only reason I'm buying another is because of suffering a lightening strike, The EC-550 we are using now works, but, doesn't work right. Lightening strikes does weird things to electrical circuits. I know. We replace just about everything electrical. The techs @ Precision Temp helped me over the hump after the lightening strike. getting the unit to work. However, this winter, the unit is giving up the ghost. So, time to replace with a new unit.
Again, my sincere thanks to Precision Temp.

We are full time RVers. Our hot water wasn’t turning on. We emailed Kay @ precision temp the issue. She immediately contacted Ray from the services department. He called us back within 30 minutes of our water not turning on. He help me with troubleshooting techniques, showed me how to use the multi meter. He walked me through from front to back how the electrical and gas source works on our 550-EC tankless hot water heater works. Found out that one of the main fuses tripped. We we up and running within two hours of his call. Thank you Precision temp for your timely service.
Thank you for allowing us to assist you! We truly care about our customers. Please remind your friends we are here before the sale, during the sale, and and as long as you have a PrecisionTemp unit.
We installed a RV550 EC in a remote Maine cabin with solar power.. It would not consistently ignite and/or burn continuously..No RV repair would come that far.. There was no cell coverage.I followed the service manual but got no results. I was ready to take it to the recycling center, a victim of high tech. But I called Ray Jordan at PrecisionTemp..
He clearly walked me through how to test and adjust the ignitor and vacuum switch. With an allen wrench set and multimeter I followed his directions and BINGO we have consistent and continuous HOT water. The unit may be pricey but you get Ray Jordan as well. That free available expert is worth the price.. We love the unit now that it is working perfectly after Ray's clear and simple instructions.
Thank you for the review!! We (Ray is included LOL) are always here for you.
Ordered rv550 to replace 500 love it. Precision temp is great! Excellent customer service. Thank you.
It is always great to hear from our customers. Thank you so much for your review!
Is it easy to winterize, we come up to tiny home cabin in winter a lot on weekends
Thank you for the review! Great reminder to winterize unit when not going to be used!!!
My RV-550 EC came with my travel trailer. It was not working, probably due to power surge with the previous owner, as well as related electronics. I live in a small town and my repair person was not familiar with this heater, so he relied on Ray for on-phone support. Ray was just fantastic! Very patient, and helped my repair guy methodically solve the issue, which ultimately led to replacing a couple of parts and thenneeding to replace my AC to DC converter (not part of the heater but an important part of the chain). The unit itself now works great and the service and accounting departments (shout outs to Ray and Kay) were just great.
Thank you so much Wally! PrecisionTemp is always here to help!!
We spoke with Kay from Precision temp as she is the Sales/Marketing Manager, and purchased the EC-550 model on May 16, 2022. Since we installed on July 1st, 2023, up to and including now, (after SEVERAL deep freezes), we have been EXTREMELY happy with the unlimited hot water (especially with our 500 LBS propane tank!). It literally is life changing and we LOVE taking hour long showers, especially one after the other! Thank you for the amazing endless hot water! Keep up the AMAZING products (sending a fellow camper your way).
Thank you so much! PrecisionTemp is here for you!!!
We are very impressed with the communication and speed of delivery for our new water heater. Can easily give PrecisionTemp our highest unqualified recommendation.
Purchased a rv550 water heater to replace my rv 500. Everyone I spoke with at preceision were very helpful and professional.
Very easy install. Plumbing and electrical and gas connections very similar to the rv 500, and size is virtually the same.
Couldnt find an rv dealer willing to do work the for a couple of months out, so did myself.. Seems to be working great.
Thank you so much for the review!! We are always here for you!
Hot Water in Any SeasonThe PrecisionTemp 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.
The Proof is in the POWERWith 55,000 BTUs—the highest hot water output in the industry—and built-in freeze protection, the 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.
More Hot Water. Less Propane.With higher efficiency and 55,000 BTUs, the 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.
