Girard Product Tankless Water Heaters: Endless Hot Water for the Road

For RV owners who refuse to compromise on comfort, Girard Product has established itself as a leading name in RV water heaters. Rather than relying on conventional 6- or 10-gallon tank units that limit your hot water supply and demand long recovery times, Girard engineers purpose-built, on-demand tankless systems that deliver a continuous flow of hot water whenever you need it — whether you're showering after a long hike, washing dishes at a remote campsite, or doing laundry on the go.

The Girard Tankless Water Heater Lineup

Girard's product range spans several model families, each designed with the unique demands of RV living in mind. The flagship GSWH-2 is a third-generation tankless propane water heater that represents the current pinnacle of Girard's engineering. It is also notable for a significant industry achievement: the first induced draft water heater in the RV industry. The lineup also includes the GSWH-1 and the GSWH-1M, which offers adjustable BTU settings ranging from 18,000 to 36,000 for greater flexibility across different RV sizes and usage profiles.

What Sets Girard Apart: Technology & Performance

At the heart of every Girard tankless water heater is an onboard microprocessor that continuously monitors inlet water flow, inlet water temperature, and outlet water temperature, then regulates the burner to maintain a consistent, precisely set temperature. This eliminates the cold-water surges and scalding fluctuations that plague simpler systems.

• 42,000 BTU output — delivers optimal performance for typical RV plumbing systems at a flow rate of 1–1.5 gallons per minute
• Digital User Control Panel (UCP) — allows temperature adjustment between 95°F and 124°F, with Fahrenheit/Celsius toggle, live outlet temperature readout, and on-screen error codes for easy diagnostics
• Freeze protection — built-in safeguards make these heaters reliable for four-season and winter camping use
• Ultra-quiet brushless motor — operates on 12V DC power drawing less than 3 amps, virtually silent compared to traditional tank heaters
• Propane efficiency — Girard tankless heaters use approximately half the LP gas of a comparable six-gallon tank heater for the same amount of hot water
• Drop-in installation — compact dimensions fit any standard tank water heater cut-out opening with no bypass plumbing, no anode rods to replace, and no tank to drain; conversion door kits are available for Atwood, Suburban, and Dometic retrofits

Why Go Tankless with Girard?

Traditional RV tank water heaters force you to manage limited hot water reserves and wait up to an hour for a full tank to reheat. Girard's tankless approach eliminates recovery time entirely, heating water only on demand — which also means no wasted energy maintaining a standing tank of hot water between uses. The result is a system that extends your boondocking range, conserves propane, and frees up valuable storage space in your rig. The GSWH-2, for example, takes up less than half the space and weighs roughly one-third as much as a conventional 10-gallon water heater.

Backed by a two-year limited warranty and supported by comprehensive installation documentation and troubleshooting resources, Girard tankless water heaters are trusted by both RV manufacturers and aftermarket upgraders alike.
