The compact Aqua-Hot 125 can be installed inside/under cabinetry or furniture. This highly efficient system operates as the van’s heating system and continuous hot water supply. As many as 3 heat exchangers (black units in photo) can be placed throughout the van to bring heat where needed. The burner is installed on the underside of the van chassis for noise reduction and exhaust.

• All in One Unit – Fast and easy installation, one unit provides heat and continuous hot water.
• High Altitude Ready – Adjusts O2 and fuel mix to optimize flame for altitudes up to 11,000ft. Will not soot up and does not require the same maintenance required on other systems.
• Great for Off-Grid – Uses the vans on board diesel fuel for all heating and hot water needs with the option to use the electric element when shore power is available.
• Continuous Hot Water – 110-120F at .8 gpm for kitchen and all water needs.
• Quiet – The combustion unit is installed outside the van with its own exhaust, while low decibel fans provide heat inside.
• Night Mode – Provides ample heat with further noise dampening.
• Dual Fuel – Either diesel via the van fuel tank or shore power electric.
• LCD Controller – Up to 3 independently controlled zones, intuitive controls -plus test and diagnostic tools.

At its most basic level, Aqua-Hot hydronic heating uses tubing to run hot liquid into heat exchangers that disperse heated air into living areas. Coils, with potable water running through them, wrap around the boiler to transport hot water to faucets and appliances. A variety of heat sources are used depending on the system, but all use some combination of the vehicle’s engine surplus heat, diesel fuel or propane and AC shore power.
