"When a tankless heater fires up, it senses the temperature of the incoming water and a computer microprocessor determines the amount of energy that's needed to deliver the water at the temperature setpoint and flow rate," explains Michael Stebbins, president and founder of trutankless, a manufacturer.
Other advantages, assuming the tankless heater is working properly, are an instant and steady supply of hot water and, in many cases, some savings in the cost of heating water.
For homes that use up to 41 gallons of hot water daily (probably a two-person household), the DOE estimates savings of 24 to 34 percent on the cost of providing hot water via a tankless heater compared to a conventional storage-tank heater.
A disadvantage is that ittakes up a bit more space than the tankless heater.
We could have gone solar with rooftop photovoltaic collectors to heat our water, or chosen an on-demand, tankless heater to replace the dinosaur we took out.
The maximum flow of a tankless heater is limited by the power output of the heating element and is also greatly affected by the temperature of the incoming water.
The average home center price for a tankless heater is $1,000, plus about $200 for a stainless vent.
(A tank heater continuously warms the water, even when it's not needed; a tankless heater activates only on demand.)
