Precision Temp RV-550 Tankless Water Heater
With four-season versatility and multiple venting options, the Precision Temp RV-550 Tankless Water Heater is the only water heater you'll ever need. It allows all of the Tiny House's occupants to shower comfortably by producing endless hot water. It is not limited to a few minutes supply of hot water as with low-end tank type units. Nothing worse than having the hot water shut-off mid shower when you have soap in your eyes!
The RV-500 efficiently and conveniently performs with up to 55,000 BTU's of power. At a flow of 1.5 gpm it can provide shower temperature water with incoming temperatures as low as 40 degrees. A 20lb tank of Propane (a barbeque-type tank) will provide approximately 940 gallons of shower temperature water.
The RV-550 is quiet and efficient. For the same amount of propane 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 50% less propane.
Hot Water in Any Season
Whether on cold East Coast winter evenings or on sunny days in Southern California, an endless flow of hot water (or until your water tank is empty!) for the ultimate Tiny House Hot Shower.
The Proof is in the POWER
With 55,000 BTUs—the highest hot water output in the industry—and built-in freeze protection, the RV-550 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.
Without a tank to keep hot, many people report that they use up to 50% less propane. Tiny House'rs owners love the lower energy consumption and ability to be powered by off-grid solar solutions.
