Question 1

WHAT IS A TANKLESS WATER HEATER?

Accepted Answer

Tankless water heaters are compact in size and provide a steady flow of hot water for as long as you need it. Rheem tankless gas water heaters are more energy efficient than conventional water heaters, because the tankless models eliminate the need for reheating stored water.

Question 2

HOW CAN I DETERMINE WHICH WATER HEATER IS RIGHT FOR ME?

Accepted Answer

Choosing a water heater is based on your family size and how much hot water you will use in one continuous hour. We call it Peak Hour Demand.

Question 3

CAN IT BE INSTALLED IN THE SAME PLACE MY OLD WATER HEATER WAS INSTALLED?

Accepted Answer

As long as enough combustion air is provided, tankless water heaters can be installed in a utility room, garage, basement or attic, or on an outside wall . Plus, they can be installed in locations where a storage water heater may not fit. The Digital Temperature Controller can be mounted in any room.

Question 4

HOW MUCH MORE DO THEY COST TO PURCHASE?

Accepted Answer

Generally, a tankless water heater will cost about 2 to 2-1/2 times as much as a standard water heater to purchase and install. Keep in mind that in addition to lower operating costs, useable square footage is gained by choosing tankless!

Question 5

HOW MUCH CAN I EXPECT TO SAVE ON MY MONTHLY BILL IF I INSTALL A TANKLESS WATER HEATER?

Accepted Answer

Test results have shown that a tankless gas water heater costs about 40% less to operate than an electric water heater, and about 30% less than a natural gas water heater.

Question 6

CAN I USE A RECIRCULATION LINE WITH RINNAI TANKLESS WATER HEATERS?

Accepted Answer

Yes, a recirculation pump can be a great addition to your Rinnai tankless water heater system when continuous, on-demand hot water is needed. Plus, the modulating technology and minimum fire rating of the Rinnai tankless rack system enables it to maintain consistent temperature in a return line with limited waste. In that case, it only uses the energy necessary to keep the line heated when in use.

Question 7

WHAT IS THE BEST TEMPERATURE SETTING FOR A WATER HEATER?

Accepted Answer

For most people, a comfortable setting is about 120 degrees Fahrenheit. Manufacturers use this number as a pre-setting for many new water heaters. For older models, setting the thermostat to medium should do the trick.

Question 8

WHY DO I KEEP RUNNING OUT OF HOT WATER?

Accepted Answer

If your hot water keeps running out much faster than it used to, your home is likely in need of water heater repairs. Your water heater could have a broken dip tube, which should prevent cold and warm water from mixing in your tank. Another possible problem could be that the lower heating element in your electric water heater has failed. While some of these issues can be fixed with repairs, it may be necessary to plan for a new water heater installation in the near future.

Question 9

WHY DOES MY WATER HEATER KEEP LEAKING?

Accepted Answer

Water heaters can spring many different kinds of leaks. Though you might not think a leak is something to worry about, according to Plumbing Manufacturers International, 13.7% of all water use is the result of leaks. If you notice your water heater is losing water, take a closer look. Sometimes, the internal tank has a crack, or one of the pipe fittings has become loose. Try to see where the leak is coming from to better explain the issue to water heater repair services over the phone. While leaks with a definite source can often be patched or repaired, a widespread leaking problem could mean that your whole system needs replacement.

Question 10

WHY DOES THE WATER TAKE SO LONG TO HEAT UP?

Accepted Answer

Slow wait times generally have to do with the plumbing in the home and are rarely cause for concern. Ranch-style houses tend to have longer pipelines, which means it takes longer for warm water to reach the faucet. You might need to call pompa plumbing to alter your home’s water circulation system to remedy this issue.
