Raypak® H7-1503A 1077471

Time-honoured technologies unite with cutting-edge advancements in Raypak's MVB modulating vertical boiler. Small space is no longer a problem and our compact design fits through a 32 in door opening to make it the perfect choice for those hard-to-reach retrofit projects. The MVB is built to last, from the structural steel base to the stainless steel flue wrapper. The built-in Versa IC Integrated Control platform precisely tracks the heating load to eliminate costly overshooting and the 7:1 turndown ensures high efficiency throughout the firing rate and actually increases efficiency during part load, right when you want it.
