hot water heat zone valves have a three-pass round coil structure. A conical coil is used for the effective protection of the furnace wall at the boiler end. This product is equipped with an advanced combustion device and is fully automated in operation. After the burner ignites the fuel, flame fills the round coil tubes and transfers heat by radiation through the tube wall (first pass). The high temperature flue gas gathers at the back door and then turns to the convection tubes section (second pass), where heat transfer takes place by convection. The flue gas gradually cools down here and flows to the front door, where it is reversed and goes into the third pass. After that, it enters into the chimney through the economizer and is released into the atmosphere.
hot water heat zone valves.This type of heater is delivered as a whole, and is installed on site, it only needs to connect thermal gas(oil) piping and electricity to start operation. The heater has four heating areas: furnace radiation heating area, the first convection tube bundle heating area, the second convection tube bundle heating area and economizer (waste heat boiler).
In this video, This Old House plumbing and heating contractor Richard Trethewey explains how to create zones in a hot-water heating system. Steps: 1 Turn off cold-water line to boiler; shut the electricity to boiler. 2 Drain water from boiler, if there's
