Why Use a Tankless Water Heater?
Endless Hot Water: Since there is no tank to fill, there is no end to your supply of hot water. Depending on the model, Takagi Tankless water heaters deliver between 200 gallons and 500 gallons of hot water every hour on demand. Tankless systems guarantee that an endless supply of water is available to residences, commercial spaces or anywhere a constant source of hot water is needed.
Space-saving and Easy Installation: A standard FLASH water heater, taking up only 2.2 cubic feet of space and 60 pounds, is about the size of a suitcase. This allows for installation in spaces with limited area or even outdoors with no enclosures.
Money & Energy Savings: Since a tankless water heater has neither a storage tank to keep heated all day, nor a pilot light, it burns gas only when you need hot water. This eliminates standby heat loss, which can be as high as 3-4% every hour for storage tank type water heaters. This higher efficiency can allow you to save up to 50% off your utility costs.
High Quality (no more tank leaks): The Takagi Tankless Water Heater is made using the best quality material for durability and long life, unlike storage tanks which are designed to eventually rust and be thrown away. The Takagi tankless system uses all copper and brass water ways, stainless steel burners, a rust resistant baked polyurethane finish, and even has pipe freezing protection.
Enviromentally Friendly: The Takagi Tankless Water Heater is the only product of its kind to receive SCAQMD (Southern California Air Quality Management District) approval for it's low emissions (CO, Nox) With high thermal efficiency, Takagi systems use much less fuel than traditional systems.
Many Applications: Space Heating, Floor Heating, Re-circulation System, Large Volume (such as hotels, apartments or industrial plants) and more.
