Caleffi, Milwaukee, Wisconsin, announces its new 290 series service valve kits specifically designed for tankless
water heaters, combi boilers, and electric tank-type water heaters. The contractor-friendly valves connect directly to standard 3/4-inch MNPT nipples on tankless water heaters to allow for efficient isolating, flushing, and servicing of the heaters. Variations of the kit are available with the 520 series TankMixer. These codes add point-of-distribution temperature control featuring its AngleMix thermostatic mixing valve and cold-water tee with recirculation connection.
