The I-Series boiler from Rinnai is designed to provide simultaneous space heating and DHW. There is no interruption if someone uses hot water during a heating cycle. The technology includes a bypass servo valve that enables control of the hot water temperature. The boiler is available in both combi and heat-only models and comes standard with a multi-zone heating control. It will be available in July.
