These systems eliminate standby energy losses that occur in storage tank systems because they heat water only on demand. A propane instant water heater is compact in size, provides superior energy efficiency, and delivers an endless supply of hot water.
Tankless water heaters can average a flow rate of about 222 gallons per hour, more than three times higher than a standard 50-gallon electric storage tank water heater’s delivery rate of 62 gallons in the first hour. This dramatic difference in performance can mean the difference between taking a hot shower and a cold shower!
Since a tankless system can provide 2 to 3 gallons of hot water per minute, it’s unlikely that your family will ever run out of hot water!
