Tankless Water Heaters

Despite the benefits there are some things to consider before you decide to install a tankless water heater. Most models require at minimum a ¾ inch gas line to supply enough gas to the unit. A 7.4 gpm unit can use 199,900 BTU at peak operation as opposed to a 40 gallon tank type water heater that uses around 40,000 BTU. In some cases the gas line is not sufficient and a new dedicated line may need to be run from the meter to supply the unit which adds to the cost of installation. A tankless water heater costs about 3 times as much as a regular tank type and installation costs are higher because of the extra labor involved as well as materials. Gas fired tankless water heaters require a special sealed, stainless steel venting because they use an electric blower to force the exhaust gases outside. This means that your old venting is not able to be used at all. It does mean though that they can be vented through an outside wall instead of out the roof. If you opt for an electric model gas supply and venting problems are eliminated but if your service is not able to handle the amperage of the unit it may need to be upgraded. Also there are issues with the hardness of the water here in Rio Rancho and surrounding areas and tankless type water heaters can sometimes be prone to build up inside the heat exchanger coil. There are ways to clean and prevent this buildup but they are extra costs to consider.

A tankless water heater is not for every household but the benefits of reduced energy costs with unlimited hot water is a big draw for people. They are fairly straight forward to install and the extra cost of installation will be eventually paid back through energy savings over the years. Most models come with a 10 year warranty on the heat exchanger which exceeds that of the average tank type model. Always research before you decide to purchase to make sure the model you select is right for your situation. If you do finally decide to install a tankless water heater you can be assured of cheap unlimited hot water for many years to come.
