Tankless water heaters heat water only when you need it - no standby losses, no waiting on a recovery cycle, and no oversized tank in the basement. They cost more upfront but last roughly 2× as long and never run out of hot water during a busy morning.
Why go tankless
Tankless wins for households with high or variable hot-water demand:
Endless hot water - multiple showers + dishwasher simultaneously
20-30% lower water-heating energy use
Lifespan 18-20 years (2× tank lifespan)
Compact wall-mount footprint frees up basement space
ENERGY STAR-certified condensing models
Sizing tankless properly
Sized in GPM (gallons per minute) of simultaneous demand. Common KW sizing:
1-2 bathrooms, 1-2 people: 6-7 GPM
2-3 bathrooms, family of 4: 8-9 GPM
Large home with soaker tub or simultaneous demand: 10-11 GPM
Cold inlet water in winter (5°C) reduces effective output by 20-30% - we size for design conditions
