The Benefits of Going Tankless: Save Money, Save Energy

Tankless water heaters use 24-34% less energy than conventional storage water heaters in homes that use 41 gallons or less of hot water daily. They also last significantly longer, averaging a lifespan of 20+ years with proper maintenance, compared to 10-15 for a standard tank. The key to unlocking this longer lifespan is proper sizing and professional installation. The Department of Energy’s comprehensive guide to tankless water heaters explains the efficiency math, sizing considerations, and factors to evaluate before making the switch.

Tankless Installation Scenarios We Handle

These are the most common situations Calhoun homeowners bring to us for tankless water heater installation.

This is the most common installation scenario. We handle the full conversion—removing the old tank, upsizing the gas line if needed, installing the new unit, and setting up proper condensate drainage and venting. Most conversions are completed in a single day.

New construction offers the cleanest opportunity for tankless installation, no conversion challenges, and we can spec the gas line and venting correctly from the start. We work with builders and homeowners on new construction installations throughout Gordon County.

Large households, homes with multiple bathrooms in simultaneous use, and homes with high-demand fixtures sometimes benefit from a second tankless unit serving a specific zone. We assess demand loads and design multi-unit configurations that ensure consistent hot water throughout the home.

Anderson Heating, Air & Insulation: Calhoun’s Tankless Water Heater Installation Team

Can my home handle a tankless water heater?

Most homes can, but the installation sometimes requires upgrades. Gas tankless units need an adequate gas line size. Older lines may need to be upsized for the demand, for example, while condensing models require a drain for the condensate. Electric models need significant electrical service capacity. We assess all of these before recommending any equipment.

How much does a tankless water heater installation cost compared to a tank replacement?

Tankless units carry a higher upfront cost associated with both equipment and installation. The savings come over time through reduced energy consumption, since tankless systems heat water on demand rather than maintaining a hot tank around the clock. We’ll show you the estimated payback timeline for your household’s usage before you decide.

How long does a tankless water heater installation take?

Most installations complete in a single day. Projects requiring gas line upgrades, new venting runs, or electrical panel work may take longer. We assess all existing infrastructure before starting and give you a clear timeline upfront.

Will a tankless water heater actually meet my household’s hot water demand?

Properly sized, yes. Tankless units are rated by flow rate in gallons per minute. We calculate your household’s simultaneous hot water demand, including showers, dishwasher, and laundry use, and size the unit accordingly. Undersizing is the most common mistake in DIY or improperly planned installations.

What maintenance does a tankless water heater require?

Annual descaling is the primary maintenance requirement for tankless units in most areas. We flush the heat exchanger with a descaling solution to remove mineral deposits, inspect the inlet filter and flow sensor, check the venting and gas connections on gas units, and test ignition and performance. Most manufacturers require annual service for warranty compliance.

We install gas and propane tankless water heaters from leading brands including Rinnai, Navien, Rheem, Noritz, and Bosch. We also install whole-home recirculation systems that eliminate the wait for hot water at distant fixtures. After installation, we recommend you protect your system with our annual tankless tune-up service to prevent the scale buildup that’s the leading cause of premature tankless failure.

Tankless installation is a strong fit when your current tank is at end of life and you want to upgrade efficiency, you’re expanding your family or home and need more hot water capacity; or you’re interested in reducing standby energy loss from keeping a large tank heated all day. If you’re not sure if tankless water heaters are right for you, give us a call. Our techs will provide a preliminary analysis based on your specific needs.
