Looks promising.
We review the Alde system and ask the big question; is the Alde better than a traditional RV furnace and water heater?

Efficiency: Alde vs Traditional Furnaces and Water Heaters
The majority of truck campers on the market use either a Suburban or Atwood/Dometic furnace with 20,000 to 30,000 BTUs. There are exceptions, but this is the BTU range for most truck campers.
During operation, the amp draw of Suburban 20,000 and 30,000 BTU furnaces is 6.5 and 8.5-amps respectively. The amp draw of Atwood/Dometic 20,000 and 30,000 BTU furnaces is 4.8 and 7.5-amps, respectively.
The majority of truck campers on the market use either a Suburban or Atwood/Dometic water heater with either 4-gallons or 6-gallons of water capacity.
The Suburban water heaters range from 9,000 BTU (4-gallons) to 12,000 BTUs (6-gallons) and draw 13-amps. The Atwood/Dometic water heaters range from 8,800 and 10,000 BTU (6-gallon) and draw 12.7-amps.
We were unable to find data on the propane consumption for Suburban or Atwood/Dometic furnaces or water heaters.
The Alde 3010 can be configured to either 11,000 or 18,700 BTU. For both heat and hot water, the Alde system draws a maximum of 1.9 amps for about three seconds when starting on 12-volt DC.
After those three seconds, there are two Alde components that cycle on and off depending on the temperature of the glycol; a combustion fan (0.4 amps), and a circulation pump (0.2 amps). The Alde fan and pump only run when the glycol needs to be heated.
Adding the draw of the combustion fan and circulation pump together, the Alde system draws about 0.6-amps of 12-volt power when running off propane. This explains why the Cirrus 920’s batteries only drop a tenth of an amp or two overnight. You read that right.
When running, the Alde system consumes 0.9 pounds of propane per hour. Alde reports that the 3010 system can operate for two weeks on a 20-pound propane tank. This mirrors our experience as well.
Based on the data and our first-hand truck camping observation, the Alde offers game-changing 12-volt and propane efficiency.
