Girard Tankless RV Water Heater
The RV Industry’s First On-Demand Induced Draft LP Gas Tankless Water Heater!
• Instant hot water*
• Unlimited Hot Water
• No Recovery necessary
• No Old Fashion Storage Tank
• Energy Efficient-Dual BTU Burner
• Environmentally Friendly

The Girard Products’ GSWH-1 Tankless Water Heater incorporates a power blower that forces the combustion air through the heat exchanger (Induced draft). This patent pending technology results in a unit capable of providing

• Higher Combustion Efficiency than atmospheric heaters
• Heat Transfer Efficiencies in excess of 90%
• Higher Wind Resistance Performance
• No Adjustments necessary at High Altitudes
• High Burner Power in a small footprint
• Quieter Performance

How a Tankless Water Heater Works:
1. A hot water tap is turned on.
2. Cold water enters the heater.
3. A water flow sensor detects that water is flowing.
4. The microprocessor based circuit board automatically ignites the burner.
5. Water Circulates through the Heat Exchanger.
6. The water is heated to the set temperature.
7. When the tap is turned off, the unit shuts down.

It’s the Flow that Makes it Go!
The GSWH-1 Tankless Water Heater Operation is literally based on the flow of water. That is to say, that the temperature of the hot water coming out of the hot water faucet is determined by how open or closed the hot water faucet is; the faster the flow, the cooler the water; the slower the flow, the hotter the water. By adjusting the flow, RV’ers can literally have endless hot water!
It’s Green!

The Girard Tankless RV Water Heater uses up to 60% less LP Gas than storage tank model water heaters since the GSWH-1 only uses energy when hot water is demanded. There is no pilot light to burn even if no hot water is needed. A storage water heater loses heat just sitting there. Even insulated tanks lose heat that goes right out the flue. The Dual BTU feature makes sure that less gas is used if the temperature of the incoming cold water is relatively warm. It doesn’t take as much energy to heat warm water. The GSWH-1 is lightweight and since there is no storage tank that could weigh as much as 90lbs, less fuel is used to tow or carry it.
