SYMPTOMS

Signs you should consider a tankless water heater

If your water heater is acting up, one visit is usually enough to tell you whether it needs a repair or a replacement. Here are the most common warning signs:

  • • Your tank water heater is 10 years old or older
    • Hot water runs out partway through the second shower
    • Your tank rumbles or shows rust at the base
    • You want back the floor space a 50-gallon tank takes up
    • Gas bills keep climbing while your hot water use stays flat
    • Your household grew and hot water demand grew with it
    • You are finishing the basement or remodeling a bathroom
    • Scale and sediment keep shortening your tank’s life

If any of these sound familiar, call (614) 705-2041. Most homes get a clear recommendation in one visit.

FAQs

Common questions about tankless water heaters

How much does a tankless water heater cost in Columbus, OH? +

Total installed cost depends on the unit size, gas line work, venting route, and whether we are converting from a tank. You get an itemized written estimate after the in-home assessment. You approve that price before any work starts.

How long does tankless installation take? +

A tank-to-tankless conversion usually takes four to eight hours, depending on gas line and venting work. Replacing an existing tankless unit is often faster because the venting and gas supply are already in place.

Should I choose Rinnai or Navien? +

Both are condensing units with a 15-year residential heat exchanger warranty. Rinnai's SENSEI RX reaches 0.98 UEF and runs on natural gas or propane without a conversion kit. Navien's NPE-A2 has a built-in recirculation pump and buffer tank and can often reuse a 1/2 inch gas line up to 24 feet. We recommend one after measuring your gas supply and venting route.

What warranty comes with a tankless installation? +

Rinnai and Navien both cover the heat exchanger for 15 years and parts for 5 years on residential installs. We register your unit with the manufacturer so that coverage starts on install day. Bedrock also provides a written warranty on our labor.

Does a tankless water heater work with Columbus hard water? +

Yes, with maintenance. City of Columbus water runs about 7 grains per gallon of hardness, and scale builds on the heat exchanger over time. We install service valves for annual flushing and can pair the unit with a water softener.

Will my existing gas line support a tankless unit? +

Many whole-home units need a 3/4 inch line. Navien's NPE-2 series can run on 1/2 inch pipe up to 24 feet, which helps on some retrofits. We check your meter and pipe size during the assessment and include any upgrade in the quote.

How much will I save on energy? +

The U.S. Department of Energy estimates tankless units are 24 to 34 percent more efficient than tank models in homes using 41 gallons or less of hot water a day. Most tankless units also last more than 20 years. Your savings depend on household size and gas rates.

Why does hot water take a while to reach some faucets? +

Tankless units heat water on demand, so water already sitting in the pipes runs cold first. Recirculation solves this. Navien NPE-A2 and Rinnai RXP models have a pump built in, and we can add a dedicated return line where needed.

Do you handle permits? +

Yes. Tankless installs in Columbus and surrounding municipalities need a plumbing permit and often a gas permit. We pull every required permit and meet the inspector on site. Permit costs are part of the quoted price.

Are your plumbers licensed and insured? +

Yes. Bedrock holds Ohio plumbing license #PL50124 and carries full liability insurance. Our techs are trained on gas line sizing and condensing tankless venting.
