SECTION III: GENERAL INFORMATION

FEATURES

The Bradford White EVERHOTIGI series tankless water heater is a high output, high efficiency appliance, which heats the water continuously as hot water is being drawn for use. Unlike tank type storage water heaters, this water heater does not store hot water. The burner operates whenever there is a demand for hot water and is off when the hot water flow stops. Hot water is continuously supplied for any length of time required, as long as the specified flow rates are not exceeded. There is no need to set the temperature higher than required for sufficient capacity. The EVERHOT water heater has sufficient capacity to supply several hot water faucets simultaneously. The hot water flow capability will be dependent upon the temperature of the outlet water selected. More detail can be found at the beginning of Section II, “Specifications” section in this Installation and Operating Instruction Manual. Your plumbing professional should determine your hot water requirements before installing this water heater to be sure the capacity is sufficient for your application.

The IGI series water heaters are designed to be installed on or near an outside wall for indoor installation only. The water heater is compact (23 1/2” (59.7 cm) H x 13 5/8” (34.6 cm) W x 8” (20.3 cm) D) and mounts on a wall using the supplied wall bracket. No floor space is needed and the water heater can be mounted at a height convenient for servicing.

The weight is less than 50 pounds (23 Kg) and can be installed by 1 person.

The burners ignite within 3 seconds of water flow (1/2 gallon/minute (1.9 L/m) minimum) by direct spark ignition. There is no standing pilot.

A variable speed combustion air blower forces the combustion air supply into the burner compartment.

Direct vent design uses only outside air for combustion. The venting system is a coaxial design requiring a single 5 1/4” (13.3 cm) hole through the outside wall or roof. Vent pipe fittings have internal gaskets for a tight seal to prevent leakage of flue products and combustion air.

The burner flame is continuously monitored and modulated to match the heating requirements of the water flow. Temperature and flow sensors continually monitor the water flow and outlet water temperature and adjust the burner and combustion air blower to maintain temperature.

The IGI model series have a digital temperature control integrally mounted to project through the front panel of the water heater. The outlet water temperature is adjustable from 96-160°F for residential models (IGI-180R series) or 96-180°F for commercial models (IGI-180C series). The front panel temperature control also displays fault codes if the water heater malfunctions to assist with servicing the water heater. No installation is required for the main temperature control.

In addition to the main temperature controller, up to two optional bathroom temperature controls are available on the residential models for setting the water temperature in the bathroom fixtures up to 120°F.

The heat exchanger coil is provided with anti-freeze heaters for protection in cold climate conditions to ambient temperatures as low as -30°F (-34°C). Drain solenoids should be installed to drain the water heater in the event of a power failure.

The water heater is very quiet in operation.

IGI-180C, IGI-180R specifications

Bradford-White Corporation is a well-known name in the water heating industry, offering a range of reliable and efficient products. Among its noteworthy offerings are the IGI-180R and IGI-180C indirect water heaters. These models exemplify the company's commitment to quality and innovation, featuring robust designs and cutting-edge technologies.

The IGI-180R and IGI-180C units are designed to provide a consistent supply of hot water for residential and commercial applications. Both models have a storage capacity of 180 gallons, making them ideal for settings that require large volumes of hot water, such as restaurants, schools, and larger households. Their large tanks ensure minimal wait times and a reliable hot water supply, even during peak usage periods.

One of the key features of the IGI series is their indirect heating capability. Instead of relying on electric elements or gas burners, these heaters use a separate boiler or heating system to provide the necessary heat. This allows for more efficient operation, as the water is heated more evenly and effectively. The models integrate seamlessly with existing boiler systems, making them an excellent choice for those looking to upgrade or expand their hot water capabilities without extensive modifications.

Both the IGI-180R and IGI-180C incorporate advanced insulation technology, minimizing heat loss and improving energy efficiency. The high-density foam insulation encases the tank, keeping the water hot for longer periods and reducing energy costs associated with reheating. This insulation also contributes to a longer lifespan for the unit, as it reduces the wear and tear on the heating systems.

Another pivotal characteristic of these units is their durable construction. Bradford-White utilizes high-quality materials and rigorous manufacturing standards, ensuring that the IGI models withstand the test of time. The tanks are constructed from heavy-duty steel with a glass lining that protects against corrosion and sediment buildup, enhancing the longevity and performance of the water heater.

Lastly, both models come equipped with a range of safety features, including an integrated Pressure Relief Valve and a temperature control system. These elements safeguard against overheating and pressure issues, ensuring safe operation.

In conclusion, the IGI-180R and IGI-180C indirect water heaters by Bradford-White Corporation stand out for their efficient, reliable, and durable design. With advanced heating technology, excellent insulation, and robust safety features, they are a smart investment for any hot water demand scenario.
