Hydronic Heat — Now Without Diesel
Unlike diesel-only tankless water and hydronic heaters, the TwinTemp runs on propane and can be used in all motorhomes, fifth wheels, horse trailers and towables.
In addition to the versatility of propane, the TwinTemp Junior offers greater heating efficiency, whisper-quiet operation, and safer flue gas temperatures.
Dual-Source Unlimited Heat
With a 55,000 BTU propane burner—the highest hot water output in the industry—and a 1500-watt electric element, the TwinTemp Junior delivers on-demand, continuous hot water and hydronic space heating.
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 and Heat. Less Propane.
With higher efficiency and 60,000 BTUs, the TwinTemp Junior produces more hot water than traditional water heaters.
With higher efficiencies, many people report that they use up to 50% less propane. Owners love the lower operating costs and fewer fill-ups.
