The International Builders’ Show often provides a useful view of what’s on the mind of builders and product manufacturers. This year, smart-home technology was one of the dominant themes. From kitchen and bath products to water heating, manufacturers are continuing to expand the home-automation features of their products. Tankless water heater manufacturer Rinnai, for instance, announced additional smart-home platforms that integrate with the company’s products. The company says it is now the first water heater company to integrate with Samsung SmartThings, allowing owners of tankless water heaters to use a Wi-Fi module to control the unit’s water temperature and recirculation.

“SmartThings allows homeowners to connect their devices and manage them as one,” said Mark Buss, vice president of marketing for Rinnai. “This gives homeowners more convenience and control over their tankless water heater than ever before.” Rinnai also supports voice control for both recirculation and water temperature with Amazon Alexa and Google Home.

Rinnai also launched a new I-Series boiler for the residential market. The I-Series boiler offers simultaneous home heating and domestic hot water production. That means if the heat is running and someone in the home wants to take a shower, the heat is not interrupted as it is with many traditional boilers in existing homes. The technology also includes an innovative bypass servo valve, which enables precise control of the hot water temperature. The boiler is available in both combi and heat-only models, and comes standard with multi-zone heating control.
