Considering a Tankless Water Heater in Your Bathroom

Traditional tank-style water heaters are sometimes adequate to keep up with intermittent use – a load of laundry here, washing a few dishes later, while someone else is cleaning up elsewhere. It’s when two or three application points are in use at once and one of those is someone trying to enjoy a warm shower that traditional water heaters can’t keep up. The shower turning cold is a nuisance no one needs to experience when you install a tankless water heater in the bathroom.


If your old tank style hot water heater isn’t keeping up, here are more reasons to consider installing a tankless water heater in your bathroom.

4 Reasons To Go With a Tankless Water Heater

You will enjoy instant and continuous hot water. Just think about that! Take as long a shower as you want, even while a hot-water hogging dishwasher is doing its thing elsewhere in the house. You’ll never have to get into hurry-up mode when you feel the water starting to turn cold on you, because it never will.

Great for bathroom extras. If you have a hot tub, jetted tub or garden tub. When you want a large amount of hot water in a short amount of time, without robbing the rest of the house of hot water, a tankless water heater is ideal.

You’ll save money with a tankless heater. The truth is, traditional hot water heaters are quite inefficient. If your bathroom sink is 40 feet of pipe away from the water heater, for example, then you’ve got a lot of water cooling off in that line when you turn off the tap. That’s money lost. And if you use metered water, running the sink for 10-20 seconds while waiting for the hot water to show up is more money down the drain. In addition, today’s top tankless units are Energy Star rated and have an energy factor – similar to an energy efficiency rating – in the mid-90s. Most energy experts estimate that tankless water heaters save 20% to 35% in energy costs over tradition water heaters. That adds up quickly!

You’ve got options. First of all, you can select an electric tankless water heater or a gas-fired tankless water heater. An electric model will be easier to install and less expensive initially since it doesn’t need to be vented, but energy will cost more going forward. A gas model can be used with either natural gas or propane, both of which are less expensive currently than electric heat. Secondly, you can choose the right size tankless heater to satisfy the demand in the bathroom. For single points of application such as one sink, a tankless heater with a 1 gallon per minute to a 2.5 g.p.m. should be very adequate. For an entire bathroom, tankless water heaters sporting a 3.0 to 5.0 g.p.m. are more than enough, even with a heavy user like a jetted tub.
