On Demand Water Heaters — Endless Hot Water, No Storage Tank
The math on traditional tank water heaters is straightforward and not great: you heat 40 or 60 gallons of water around the clock, whether you use it or not. When the tank runs out, you wait. On demand water heaters flip that entirely — they heat water only when you turn on the tap, and they don't run out.
For most Canadian households, the switch to on demand is one of the better home upgrades available. Lower energy bills, no cold showers, and no 60-gallon tank taking up half the utility room.
The right type depends on your fuel source and installation:
Gas on demand (propane or natural gas) — higher flow rates, lower operating cost, requires venting. The Gas Tankless Water Heaters range from 2.64 to 5.28 GPM and cover everything from a single bathroom to a full home.
Electric on demand — no gas line needed, no venting, easier installation. The Electric Tankless Water Heaters run from 11kW to 27kW and require a dedicated 240V circuit.
Portable on demand (propane) — for camping, RV, and off-grid use. The Portable Water Heaters range from 6L to 20L and need no permanent installation.
RV on demand — wall-mounted propane units for motorhomes and travel trailers. See RV Tankless Water Heaters.
Not sure which type fits your situation? Start with the fuel source — that narrows it down fast. All Camplux on demand water heaters sold in Canada meet CSA or ETL certification standards.
