It means Flammable Vapor Ignition Resistant. An ANSI (American National Standards Institute) standard went into effect in July 2003 that will prevent a water heater from igniting flammable vapors outside the combustion chamber. This helps to protect homes.
No, they are not. The consortium of manufactures agreed on flame arrestor plate technology to create the new generation of FVIR water heaters. Early in the development, Rheem researchers at their Montgomery labs discovered that flame arrestor plate designs might be vulnerable to the effects of lint, dust and oil – LDO. Rheem urged the ANSI standards be reviewed. As a result, the ANSI standard now includes testing for reliability in LDO environments. Throughout development, Rheem engineers have been highly attentive to the role LDO robustness will play on product reliability and consumer satisfaction.
The HPWH uses heat pump technology to achieve a 4.0 efficiency rating. (Residential gas is approximately 0.50; residential electric is approximately 0.60; and commercial oil is approximately 0.40). The HPWH is also ‘Energy Conservation and Environment Friendly Products’.
Choosing a water heater is based on your family size and how much hot water you will use in one continuous hour. We call it Peak Hour Demand.
Yes we do. We have a full line of standing pilot, intermittent spark, direct vent, sealed combustion and high efficiency commercial water heaters. Our Xtreme models will provide up to 756 gallons of hot water in an hour; and recover the tank contents in as little as 8 minutes! You can select from an electric model or gas model.
Yes we do. We have a full line of heat pump, hybrid solar energy, and new model of heat recovery tank. Our HR models will utilise the heating from Air condition generating hot water.
- Instantaneous type
- Storage type
In choosing the type of water heater depends on the usage. Installation area Power constraints Investment budget The cost of producing hot water
- Hot water requirements
- Room size
- Device type And the number of hot water points in each room to assess the demand for hot water.
