Cost Efficiency

Tankless units have a higher efficiency rating and lower your home’s energy consumption resulting in lower energy bills. Water is heated only when it is used eliminating the need to store and heat water 24 hours a day.

less maintenance2

Less Maintenance & Worry

The lifespan of a tankless unit is twice that of a traditional tank unit and is backed by a hefty warranty, typically 12-years on the heat exchanger.  Without a tank, there's less worry over leaks or ruptures.

allows you to set the desired temperature and prevent scalding accidents.

Condensing Units trap the condensation and reuse it provide additional efficiency and savings.
Recirculating Systems some units come with a recirculation pump eliminating the ‘cold water sandwich’ and providing instant hot water. Some systems even learn your habits, having hot water ready for you at the same time each day.

How a Tankless Works

A gas tankless water heater is an efficient appliance that uses a heat exchanger to heat water only when it's needed, which can help you save on your energy bill.

 1 Hot water is turned on.  howitworks1
 2 Water enters the appliance.
 3 The water flow sensor detects the water flow
 4 The computer signals the burner(s) to ignite.
 5 Water circulates through the heat exchanger.
 6 The heat exchanger heats the water to the designated temperature.
 7 When the tap is turned off, the unit shuts down.


Tankless Maintenance


Keep your tankless running efficiently with a check-up and flush.   Ongoing maintenance helps keep your heat exchanger free from scale buildup which impacts the efficiency of the unit and it’s lifespan.   ALL water heaters, tank or tankless can have scale buildup over time.  The good news is a tankless flush will quickly clean the buildup and lengthen the life of your appliance.

Tankless Check-up and Flush $129  
Schedule your service by calling our service department at (803) 323-5304, option 3.
Please note:  A pre-installed drain kit is necessary to run the flush service.  YCNGA installs a drain kit as part of our standard installation, but other installers may not.  If your tankless does not have a drain kit we will not be able to run the flush through your unit. 




Protect your EXTERIOR MOUNTED tankless unit during a power outage


How to drain your exterior tankless unit
 Only in the event of a POWER OUTAGE with subfreezing temps

Freeze protection comes standard on all Rinnai Tankless Water Heaters. As long as there is both power and gas supply to the appliance, freeze protection guards against outside temperatures as cold as -22°F (‐30°C) for indoor models, or as cold as -4° F (-20° C) for outdoor models when protected from direct wind exposure. Because of the “wind-chill” effect, any wind or circulation of the air on the unit will reduce the effectiveness of freeze protection.


If the Rinnai Tankless Water Heater will be dormant or loses power during a period of possible below-freezing temperatures, it is recommended the water be drained from the unit.

If the Rinnai unit or the external piping has frozen, do not operate the tankless water heater.
