Around Ohio, more and more homes are going tankless.

A tankless water heater is an energy-efficient water heating system that heats water only when it is needed. Whether you are interested in installing a tankless water heater or need repair or maintenance on your tankless unit, Kellermeier Plumbing & Heating has you covered.

For decades, our team has been providing superior heating, ventilation, and air conditioning (HVAC) and plumbing services to the Northwest Ohio area. Our expert technicians offer residents in Perrysburg, Bowling Green, Watterville, and beyond with affordable, quality service.

What Is a Tankless Water Heater?

A tankless (or on-demand) water heater is a water heater that does not require a storage tank to heat the water. These space-saving, long-lasting water heaters provide an endless stream of clean, hot water for all your appliances simultaneously without temperature fluctuations.

Tankless water heaters use gas or electric burners to heat the water on the way to your tap. When you turn on the hot water in your home, it triggers the on-demand water heater to begin drawing water into this system. Within a matter of seconds, steaming hot water is coming out of the faucet.

Benefits include:

  • Up to 96 percent thermal efficiency
  • ENERGY STAR® certified
  • Almost instant hot water
  • Significant space savings over conventional tank heaters
  • Flexible installation options
  • Reduced risk of flooding

Unlike a tank water heater, tankless heaters do not use any energy when you are not using hot water, lowering your energy bill and reducing your carbon footprint. Tankless water heaters typically have longer service lives over tank models, lasting up to 20 years.

Tankless Water Heater Installation

Tankless water heaters come in different sizes based on your hot water needs. If you anticipate that multiple people will be using hot water at the same time, you may want to consider installing two smaller on-demand tankless water heaters rather than one large unit. Doing so helps ensure you have hot water at all times.us users and helps ensure there is hot water anywhere in your home whenever you need it.

You can trust our team at Kellermeier will find the best solutions for your comfort and needs. We are a third-generation family business serving customers throughout the CITY area. We take great pride in helping you get the best value out of your HVAC and plumbing equipment.

Tankless Water Heater Repairs

When you need repair for your tankless water heater, you want it done quickly and correctly. It could be a strange noise or lack of hot water—our NATE-certified professionals will get your system running. We know how it feels to go without hot water—we promise to get there as quickly as possible!

Tankless Water Heater Maintenance

If your water supply is hard, maintenance is needed when minerals build up over time and begin to cause blockages and other problems in your equipment.

While this can also be a sign that your on-demand water heater needs repairs, unusual noises coming from your unit can also be a sign to check for limescale buildup that you can remedy through maintenance.

Your plumbing and HVAC equipment is a significant expense. Preventative maintenance, such as scheduling tune-ups and inspections, gets the best return on your investment.

“When talking with Lynette to set up the appointment I was very impressed with her professionalism. I was told the serviceman would be coming about 8:00 am. 8:10 Rick and a helper were working on the installation of a tank-less water heater. A few hours later they were done and did a great job. They cleaned up after them selves, were very friendly and professional.
Highly recommend this company and their employees. We had a tank-less installed may years ago at another house by Kellermeier and would never have another company do any work for us.”
