Tankless water heaters, also known as on-demand water heaters, provide hot water only as it is needed. By heating water only when it’s needed, tankless water heaters cut water heating expenses, while also providing continuous hot water delivery.
How tankless water heaters work
When a hot water tap is turned on, cold water travels through a pipe into the tankless water heater. Either a gas burner or an electric element heats the water. You don’t need to wait for a storage tank to fill. However, a tankless water heater’s output limits the flow rate.
Continuous does not mean unlimited
Typically, tankless water heaters provide hot water at a rate of 2–5 gallons per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones. However, even the largest, gas-fired models can have trouble meeting multiple, simultaneous demand. For instance, running a shower and dishwasher at the same time can result in more demand than many units can handle.
Choosing the right water heater
Getting too much water heater is just as bad as getting too small a unit. That’s why MoreVent techs take time to survey your water use before making a recommendation. In the event a tankless water heater isn’t a fit for your hot water needs, we’ll provide you alternatives such a a traditional tank water heater or heat pump water heater.
Tankless water heater installation
No matter which type you choose, installation day is the most important day in the life of your water heater. That’s why experienced MoreVent water heater installers take the necessary steps to prevent unnecessary future system malfunctions, ensuring your water heater operates safely and efficiently.
