Natural Gas Tankless Water Heaters

Natural Gas Tankless Water Heaters — High-Efficiency On-Demand Hot Water

If your home is on the natural gas grid, a natural gas tankless water heater is almost always the most cost-effective long-term choice for hot water. Natural gas is cheaper per BTU than electricity in most Canadian provinces, and tankless means you're only paying to heat water when you actually use it — not keeping a 40-gallon tank warm at 2am.

The performance numbers are worth knowing: natural gas tankless units typically deliver 3–6 GPM of hot water continuously. That's enough for a shower and a dishwasher running at the same time, or two showers back to back without a cold surprise.

For indoor whole-home use, the Camplux 5.28 GPM indoor natural gas unit — available in grey or white — handles 3–4 simultaneous fixtures and suits most Canadian homes with 2–3 bathrooms. For outdoor installation where venting isn't an option, the 5.28 GPM outdoor model mounts on an exterior wall and connects directly to your gas line.

A few things worth knowing before you buy:

• Natural gas and propane are not interchangeable — confirm your fuel type before ordering. If you're on propane, see Propane Tankless Water Heaters.
• Indoor natural gas units require proper exhaust venting per Canadian building code. A licensed gas fitter is required for installation in most provinces.
• All Camplux natural gas tankless units are CSA-certified for Canadian residential use.
