3 Reasons to Choose Tankless Water Heaters

I just filmed a segment on this topic yesterday for my Time Warner Cable News show called “Your Home” so this topic is on my mind today.

I think there are three big reasons why you should consider a Tankless Water Heater.
#1  Efficiency.
The Rheem tankless heater I use most often is a 94% efficient condensing unit.  (Here’s a link to the Rheem page for specs, or to Amazon to get a basic price)

That means it can convert that $1 of Natural Gas into 94 cents of hot water.  Compare that to a standard 50 gallon tank gas water heater that’s typically 60% efficient and you are getting 34 more cents out of your dollar of gas with this Rheem unit.  I also like these units because they remain Off until you open the tap and it senses flow, then it flash heats the water.  This is really nice for the households that are gone all day at work, or that have occasional hot water use.  The Rheem model I was filming with yesterday had an Energy Guide sheet saying an average family would use $198/annually in natural gas with that model installed.

#2  Space Savings.
If you are in the Southern US I would highly recommend mounting your tankless water heater on the outside of your house.  This can be a big space savings if you are replacing a tank water heater that’s mounted inside your house.  When I remodeled my house a few years ago, the tank water heater was in the pantry off the kitchen.  By mounting my new Tankless outside it netted me about 6 square feet of panty space! That’s huge!

BEFORE:  Water Heater & furnace inside a closet by the front door!
AFTER:  Tankless Exterior Mounted Rheem unit on the side of the house.

#3 Luxury.
This is probably my favorite reason to go Tankless.  I have a wife and 4 young kids and if I wanted to take a shower after the night time routine I often ran out of hot from my 50 gallon tank water heater.  Now that I’m using a Tankless water heater I can jump right in after everyone in the house has bathed/showered and NEVER run out of hot!  That’s fantastic.  Granted it doesn’t work great for encouraging water savings, but those cold showers after 5 minutes of hot water were not fun for Daddy.

I hope you found this helpful.  If you can think of some further reasons why you’ve gone tankless be sure to comment below.  Stay tuned for next week when I discuss Tankless Water Heater maintenance.
