Direct Answers
Tankless Water Heaters FAQ
Does tankless mean unlimited hot water?
It can run continuously within its rated flow and temperature rise, but too many simultaneous fixtures can exceed capacity.
Can a tank heater be directly swapped for tankless?
Not always. Gas, venting, power, condensate, and water connections may need significant changes.
Why does my tankless heater fluctuate?
Scale, flow sensors, clogged filters, gas supply, venting, crossover, or demand beyond capacity can cause unstable temperature.
