Justin Time Plumbing & Heating offers the broadest array of tankless water heating systems in northern Indiana. Gas hot water heaters are efficient and effective. You now have the choice of traditional or tankless hot water systems. Justin Time Plumbing & Heating would like to provide you with some information to help in the decision making process of your new water heater system.

How Tankless Works

When a hot water tap is turned on, water enters the tankless water heater. A sensor detects the water flow, and activates a gas heating device, which quickly raises the water temperature to a preset level.

When water flow stops, the heating device shuts off. Thermostatically-controlled tankless water heaters vary their output temperature according to water flow rate and inlet water temperature.

Unlike traditional storage tank water heaters, tankless water heaters do not store a reservoir of hot water. As a result, standby losses are reduced, which makes them an energy-efficient alternative to traditional water heating.

When water flow is detected, they begin heating water, making them highly efficient and cost effective. When the demand for water ceases, they enter standby mode and use essentially no energy.

There will always be hot water. Endless hot water - for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches our lives.

Tankless water heaters consume a fraction of the space consumed by a tank heater. They can be mounted inside or outside.

Because tankless heaters do not store water, they are less subject to corrosion than tank-type heaters. As a result, their expected equipment life is longer - possibly more than 20 years, compared with 10 - 15 years for traditional heaters. Also, because they are not heating 40 - 50 gallons of water 24 hours a day, tankless water heaters are less susceptible to leakage than tank-type water heaters.

Navien Is An Industry Leader

We are proud to service, install and perform maintenance for our customer's Navien Tankless Water Heaters.

Navien Condensing tankless water heaters are compact heating units that provide hot water as it is needed, and do not store hot water like traditional tank-type water heaters. Often, Navien water heater owners find that their units last longer than 20 years with proper routine maintenance.

Navien units also boast some of the lowest energy and maintenance costs across the water heater industry, and unlike some other tankless units they are able to produce more than 11 gallons per minute, they are very powerful units.

Key Benefits of Tankless:

  • Hot Water When You Need It: Unlike tank-type water heaters, gas fired tankless water heaters provide hot water as it is needed. When a hot water tap is turned on, a sensor detects the water flow and activates the tankless heater, which quickly raises the water temperature to a preset level. Hot can then continuously be produced virtually forever.
  • Efficiency Choices: Tankless heaters are highly efficient, in regards to their UEF ratings. Regular gas fired tanks sometimes have ratings of less than 0.60 UEF, with tankless having 0.97 UEF. . This represents a very significant improvement in energy efficiency for tankless water heater owners that can add up to hundreds of dollars in savings each year.
  • Space Saving: A great benefit of tankless water heaters is that they are wall mounted, so virtually no indoor floor space is used. They do not require a traditional mechanical space like a tank type unit.
  • Longer Service Life: Because tankless heaters do not store water, they only operate when they are needed. As a result, they are less effected by wear, tear, and corrosion than tank-type heaters. Gas fired tankless equipment life is typically 20 years or more, compared with 10 - 15 years for traditional tank water heaters.
  • Leading Edge Safety: Tankless water heaters are sealed combustion. They draw combustion air from outdoors, and have low temperature sidewall or roof venting.
  • Integrated Recirculation System: We offer Navien® water heaters. Their "A" models come equipped with ComfortFlow®, and advanced hot water recirculating system that can provide fast access to hot water whenever you need it.
