By installing a Wave 3 heater, I wanted to save on battery power and avoid noisy furnace use in milder weather.

Wave T Fitting

I used a T-fitting to tap into the propane and feed the range and water heater. I added a T and SS braided hose to reach the water heater access door area.  Another approach would have been to tap into the line under the cooktop.

Wave Under Range

Then, I removed water heater’s access door and stowed it alongside. I added a 2×4 spacer to get the removable TV arm far enough out to clear the cabinet’s edge.

Wave TV Mounted

I cut plywood to mount onto the TV arm and installed the Wave 3 to it.

I added a shut off at the end of the braided line and a three-foot rubber hose securing the valve to the wall.

The Wave 3 is in stowed in the daytime operating position.

Wave Daytime Position Olympian

The Wave in the night position allows for maximum heat toward the cabover and I have room to pass by.

Wave Night Position

I did a short test on its performance. After one-hour on high, it brought my Lance 480, a 9.5 foot non-slide, from 50-degrees Fahrenheit to 70-degrees Fahrenheit. It was 45-degrees Fahrenheit outside.

Overnight, the outside temperature dropped to 21-degrees Fahrenheit. The inside temperature was at 63-degrees Fahrenheit. I checked a couple times during the night and the inside temperature varied from a 35 to 40-degree rise from the outside temperature.

The temperature was measured at the cabover bed height. It was 10-15-degrees Fahrenheit lower at the dinette away from heater’s focus. I didn’t have any fan mixing the air. I plan on adding a couple of computer fans in the future to address this.

I really didn’t have room in my camper for a larger Wave heater. In a bigger camper, at these temperatures, I would suggest finding a way for the larger Wave 6. The Wave 6 is double the footprint and offers 150-percent of the output.

My initial view of the Wave 3 is that it fits smaller campers. It will need furnace to supplement it below 32-degrees Fahrenheit. I will be able to use it to about 55-degrees Fahrenheit on low without opening vent more than current 1/2-inch.

It sips propane. Even on high it only uses one pound every seven hours, so it would run just short of a week on one 20-pound tank. It’s dead quiet; I can’t hear it. The humidity has been maintained at 37-percent with the top vent and dinette window both cracked 1/2-inch for safety. The CO alarm hasn’t sounded.

Be sure to follow ventilation requirements and use a CO detector for safety.

Installing the Wave 3 took about hour of hands-on time, and a few more to plan. This modification cost me about $350.  In my opinion, the skill level of this modification is medium.
