The RV-550 EC tankless water heater delivers on-demand hot water efficiently and conveniently with up to 55,000 BTUs of power.

Choose between a white painted aluminum door or an unpainted aluminum door. The unpainted doors may have light scratching when they arrive but can be buffed out to a nice looking finish with a little work.

At a flow of 1.5 gpm it can provide shower temperature water with incoming temperatures as low as 40 degrees.

A 20 pound tank of propane will provide approximately 940 gallons of shower temperature water.

The RV-550 EC is quiet and efficient. For the same amount of propane as a conventional water heater, the RV-550 produces 15% to 20% more hot water. And because you are not constantly reheating a tank, many people find that they use as much as 50% less propane.

Whatever the incoming water temperature, the patented gas modulation of the RV-550 EC gives you consistent water temperature. Water as hot as you want it for as long as you want.

The RV-550 EC includes a cold weather package. Instantaneous water heaters only come on when you turn on the hot water tap. Therefore, anytime the temperature drops to 32°F (0°C), they are susceptible to freeze damage. The RV-550 EC, however, will turn itself on for short periods of time as the temperature approaches freezing. This will protect the unit down to temperatures of 20° F (If 12V power is available and your gas is left on).

Requires 12-volt connection.

Weighs 35 pounds

Frequently Asked Questions:

Q.  What does EC stand for?
A.  Electronic control.   Not only does the EC control temperature by monitoring water flow, but it also looks at temperature variations and the computer quickly makes updates.  It improves the performance, especially in marginal water flow situations, resulting in better performance all the way around. 
Q. Does the heat output modulate?
A. Yes, the water heater modulates based on water flow. With less water passing through it, the flame will be smaller so as not to overheat the water. You will mix hot and cold at the shower just like at home. The maximum temperature rise will be 88 degrees above the temperature of the incoming water. This can be achieved at 1 GPM. At 1.5 GPM, it can raise the temperature by 66 degrees.

Q. How warm will my shower be?
A. A typical shower in an RV or tiny home has a maximum flow rate of 1.5 GPM. Standard shower temperature is 105 degrees. The heater can warm 1.5 GPM flow by up to 66 degrees. So as long as your incoming water is at least 39 degrees, you'll achieve that 105 degrees at the flow of 1.5 GPM.

Q. What is the minimum temperature possible?
A. 33 degrees. Lower than that is ice.

Q. How many gallons per minute can the water heater output?
A. There is no maximum output.

Q. Does the water heater need minimum water pressure?
A. No minimum water pressure is required. But it does need a gallon of water to fill the heater before it will start. If the water is not moving or is not in the heater, it stops heating.
