Want Endless Hot Showers NOW? Five Signs a Tankless Water Heater is Right For You

Water heater leaving you out in the cold?       

A tankless might be the answer!

1) Do you have a large family and/or often run out of hot water?
If you've got four or more people who like to take showers or baths every day, then you've also got plenty of dishes and clothes to wash too, so you're using a ton of hot water and probably running out often. Large families need a tankless water heater because it heats water ON DEMAND. Regular water heaters heat a few dozen gallons of water and when it's gone, it takes a while to heat more, leaving you out in the cold. With a tankless, special coils heat the water at the time you need it, so you never run out! No more staggering showers for family members and scheduling when to run the washer.

The water flow sensor detects the water flow. The computer automatically ignites the burner. Water circulates through the heat exchanger. The heat exchanger heats the water to the designated temperature. When the tap is turned off, the unit shuts down.

2) Do you have a bulky heater in a small space?
Regular, tanked water heaters take up a lot of room in a small house, often squatting in a big chunk of floor, closet, or attic space. Tankless heaters are smaller and last up to ten years longer than a conventional heater. Your tankless will be mounted on a wall, inside or outside, freeing up space for storage.

3) Do you want to save energy and money?
Tankless water heaters are more energy efficient than regular water heaters since you don't have to pay to keep the heated water constantly hot. You're also not losing heat that's idly sitting in a tank that, while insulated, is still going to lose heat and require constant reheating. There are also tax credits and rebates you can earn by going tankless. Check it out below. All of this will save you money every year!
Graphic reads: New Tankless Technology - Newer, smaller tankless models cost significantly less, and they typically do not require larger gas lines, all of which helps narrow the cost gap with tank units. Tax credit and rebates: You can earn a federal tax credit by buying a gas or oil water heater with an energy factor of at least 0.82, which effectively covers all tankless units. Local tax credits and utility rebates may net more savings when going tankless. Payback: The higher cost for tankless can be returned over time through energy savings. Replacing a standard 50 gallon electric water heater with a gas fired condensing tankless can reduce annual energy costs by more than 60% or $318. How quickly you recoup the tankless premium ultimately depends on reducing installation costs and finding additional rebates

4) Do you worry about your water heater leaking and destroying your flooring, walls, and ceiling, plus causing black mold?

That's a valid concern, tanked water heaters leak all the time, often causing mold and water damage issues for the homeowner. Since water isn't stored in the unit, but rather heated fresh on demand, there is little reason to worry about a tankless heater leaking and/or causing a mold issue. You can rest easy and breathe freely.
Graphic reads: When a Tank fails, it may be a slow leak or a massive flood. Weakened by rust and corrosion over time, a burst storage tank can dump 30-80 gallons of rusty water in your attic or garage. That's a major mess to clean, even before a new unit can be installed. 7 out of 10 water heater failures are due to a tank bursting or failing

5) Are you tired of repairing or replacing your heater after your 6-year warranty runs out?

Navien tankless water heaters actually offer a 15 YEAR warranty on the heat exchangers. That's even more than the 12 years quoted in the infographic below. And for sure, that's a lot longer than a tanked water heater warranty, which hovers around six years. Tankless heaters do incur a higher up-front cost to install, but they save you money in gas heating every year, and last twice as long, with a longer warranty. Keep in mind that if you have hard water, you need to get a softener, as hard water is very bad for tankless heaters. And just like a tanked heater, you'll need to flush your tankless every year to keep it working nicely.
Graphic reads: Tanked water heaters last 10-12 years on average, whereas tankless water heaters last up to 20 years. In tanked heaters, minerals from water allow sediment to build up over time at the bottom of the tank, shortening its useful life and lessening its efficiency in the meantime. When a key part breaks you'll likely need to replace the entire unit. Tankless heaters prevent scale buildup. Plus, all parts are modular and easily replaceable.

Do I Need To Hire a Licensed Plumber? Your Common Questions Answered!

Help! I have a plumbing problem! Should I try to do it myself, hire a handyman or call a licensed plumber?  In Texas, there are only TWO legal options when you have a plumbing issue:  1) As the homeowner, you can fix your own plumbing, OR  2) You can hire a state-licensed, insured plumber who is working under a valid Master Plumber's number.  If you have your plumbing work done illegally, it could be a costly mistake, since damage from illegal work isn't covered by your home insurance.

7 Trees That Cause the Most Plumbing Damage - Are Any in Your Yard?

What kinds of trees do you have in your yard? You need to find out! To protect your plumbing you must know what kind of trees you have and where they are planted in relation to your sewer lines, since some trees are more trouble than others for your plumbing. Tree roots can exploit tiny cracks or holes in your sewer pipes, and use them to invade!  It's a very common problem in Central Texas to have tree roots clog, crack and even completely destroy parts of sewer lines.  Did you know that tree roots can be 2-7 times as long as the tree is tall? These roots will travel long distances seeking water. Roots can actually sense water vapor, and will follow the trail of leaking moisture straight back to small cracks, badly sealed joints, or pinholes in your pipes. Was your home built 1950-1986? Then you very likely have cast iron sewer lines which are very deteriorated and especially vulnerable to root invasion. Read more here. As you can see in the diagram above,  roots will invade
