Gas fired tankless water heaters are more and more popular throughout our service area in Starke County, Indiana. Gas fired tankless water heaters offer several unique features:

Unlimited Hot Water On Demand: 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 water can then continuously be produced virtually forever.

Efficiency Choices: With tankless UEF (Uniform Energy Factors) of up to 0.97 compared to UEF ratings of less than 0.60 for common gas fired tanks. 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: Tankless water heaters are wall mounted and they take up virtually no interior floor space. 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 outdoor, and have low temperature sidewall or roof venting.

Integrated Recirculation System: We feature Navien® water heaters. Their "A" models come equipped with ComfortFlow®, and advanced hot water recirculating system that can provide fast access to hot water throughout your application.
