How do Tankless Water Heaters Work?

Tankless water heaters, also known as on-demand water heaters, heat water directly as it flows through the unit. Unlike traditional tank water heaters that store and heat a set amount of water, tankless heaters heat water on-the-spot using electric coils or gas burners. This provides a continuous supply of hot water without the need for a storage tank.

Benefits of Switching to a Tankless Water Heater

When considering the switch to a tankless water heater, you'll find a range of compelling advantages that enhance both efficiency and convenience. These benefits include:

  • Energy Efficiency: Traditional water heaters keep a constant supply of water hot, resulting in unnecessary energy consumption. In contrast, tankless heaters only heat water as needed, reducing energy usage and lowering utility bills.
  • Space-Saving Design: Tankless water heaters are designed with space in mind. Their compact, wall-mounted units take up significantly less room compared to bulky traditional tanks, freeing up valuable space within your home.
  • Longevity: Tankless water heaters are built to last. On average, they have a longer lifespan than conventional tanks. This durability translates to fewer replacements and less overall maintenance costs over time.
  • Endless Hot Water: With a tankless system, you'll have a continuous and instantaneous supply of hot water. Say goodbye to the frustration of running out of hot water during showers or other household activities.
  • Reduced Risk of Water Damage: Traditional tanks are prone to leaks and ruptures, which can lead to costly water damage. Tankless water heaters eliminate this risk entirely, as they lack a storage tank. This gives you peace of mind knowing that your home is safeguarded against potential water-related disasters.

Switching to a tankless water heater not only addresses immediate hot water needs but also contributes to long-term energy savings and overall household efficiency. At John Stevenson Plumbing, Heating & Air Conditioning, Inc., we specialize in seamless tankless water heater installations and are committed to helping you reap the numerous benefits of this advanced water heating technology.

Frequently Asked Questions
  • Should I replace or repair my AC unit?

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
