Rinnai: The Best Hot Water Heater For Your Home

Updated: May 26, 2020

Mark Harris Homes specializes in building custom homes that are energy efficient, saving you money yearly. One of the energy efficient features that we offer with every home is a Rinnai Tankless Hot Water Heater.

Whether you are building a new home or replacing the water heater you currently have, water heaters can be a big investment for homeowners. When choosing what is best for your home, it's important to consider cost, longevity, and the efficiency of your hot water heater. If you want a more efficient and longer lasting water heater for your home, choose a Rinnai Tankless Water Heater.

Endless Hot Water

With having a Rinnai Tankless Water Heater in your home, you will eliminate the wait for hot water, reduce the risks of flooding, and you won't feel like you have to ration out your water. Rinnai Tankless Water Heaters supply your home with endless hot water, where as tank water heaters store only 30-50 gallons of water. Many traditional tank water heaters take longer to heat water, because of the larger volume of water. And once the tank heater runs out of water you are left in the cold, waiting for it to re-fill. Rinnai tankless gas water heaters heat your water with extremely efficient heating coils as it goes through the pipes, giving you all the hot water your home needs. You won’t have to wait even 15 to 25 seconds for your water to become hot, as tankless water heaters deliver two to three gallons of hot water per minute.

Energy Efficiency

Rinnai Tankless Hot Water Heaters are 40% more energy efficient than tank water heaters. Tank water heaters may heat your water when you aren't home, resulting in higher utility costs. Rinnai only heats your water as you are using it.

Saving Valuable Space

Though Rinnai Tankless Water Heaters look small, they are mighty. Most of the units are the size of a small suitcase and fit in places you'd never think they could go. Traditional tank heaters take up a lot of space in a closet, basement, or attic - space that could be used for other things. Rinnai tankless heaters are designed to be wall-mounted and can be installed inside or outside.


Rinnai Tankless Water Heaters have long lifespans. Traditional tank water heaters last 10-15 years, where as tankless can last more than 20 years. Though traditional tank heaters cost a lot less than tankless heaters, you will be saving more money in upkeep and utility costs in the long-haul by having a Rinnai Tankless Water Heater in your home. Also, Rinnai gives a generous warranty on each water heater to offer homeowners more peace of mind.

As you consider your water heating wants and needs, consider Rinnai Tankless Water Heaters.
