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, safer flue gas temperatures and no scheduled maintenance.

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. RV owners love the lower operating costs and fewer fill-ups.

TwinTemp Versus the Competition

Testimonials

Enjoying the Quiet Comfort of TwinTemp:

“Previously when I would park my coach on a site and not drive it during the winter, it was important to fill my diesel fuel tank so as to minimize condensation, which could mix with the fuel.

Since the TwinTemp burns propane, I no longer have to worry about running down the fuel level. Also, this means that if I need more propane, I can have the mobile propane service deliver it, versus having to drive my rig out to a service station for more diesel.

Once again, thanks for everything. We really enjoy the quiet comfort.”   – John C.

Hot Water in Any Weather:

“For the first time since we have owned the coach we were able to take showers with the shower valve wide open and the water stayed consistently, comfortably warm.

We were only able to do that with our Aqua Hot when the incoming water temperature was above 70 degrees. Thank you.”   – Fred B.
