Selecting And Sizing Your New Tankless Or Conventional Water Heater

If you’re in the market for a new water heater, the first step in your search is choosing between a newer tankless model or a conventional water heater. Whereas conventional models store hot water in a tank at all times, tankless models heat water only when it is needed. Because they heat water on demand, tankless heaters do not waste heat and energy when they’re not in use. Tankless heaters are more expensive than conventional heaters, but depending on your needs, a tankless heater may make up for its initial cost through energy savings.

Tankless heaters, like conventional heaters, can be powered by multiple kinds of fuel, including propane, electricity and natural gas. Your choice of heater type will be influenced by the fuel you already use and any others that might be available in your area (in Grand Traverse and surrounding counties, mainly gas and electricity). You may find that using a new fuel source for your water heater can save you money in the long run, even if you have to pay for installation.

Tankless heaters cannot produce as high a flow rate as conventional models and may not be able to supply enough water for multiple uses at the same time. You can remedy this by installing two or more tankless heaters or even separate heaters for various appliances.

After choosing a tankless or conventional model and fuel source, you will need to size your new heater. This process is different for tankless and conventional heaters. Sizing a conventional heater is based on the heater’s first-hour rating (the amount of hot water it can supply per hour) and your household’s peak-hour demand. To figure out this number, use the Department of Energy’s Energy Savers worksheet. To size a tankless water heater, you must calculate the flow rate and temperature rise you’ll need at any one time. For further explanation, go to the Energy Savers page on sizing a tankless heater.
