Boiler Zone Heating Circulation Problem - Hello, I have a Peerless boiler and recently it had been inspected by a buddy who has been in the business for 35+ years. He installed a new pressure-reducing valve in the rear which was leaking very little. I have 3 zone valves in a split-level ranch home. in a split-level ranch home.

Hot Water Boiler Piping Zone Valves - Thermostats and Zoning. A zone valve is hooked directly to a thermostat. On a call for heat, the thermostat contacts close completing the circuit to the zone valve and energizing a small motor in the zone valve. This motor opens the valve. As the valve opens an end switch in the zone valve closes.

The heated water from the boiler is fed to one side of every radiator (the feed pipe) while the other end of each radiator is connected to a separate common return pipe. This means that the temperature of the water entering each radiator is more or less the same so each radiator should heat the local environment by the same amount.

The heating boiler piping diagram at page top, courtesy of Raypak® shows the heating system circulator pump assembly (red in our sketch) on the return or inlet side of the heating boiler. By piping convention the triangle (which we surrounded in red for emphasis) points down, showing the direction of water flow.

Slant/Fin and Weil-McLain cast iron boilers have been proposed so I've read over their installation manuals. For radiant floors, both the Weil-McLain and Slant/Fin manuals recommend using primary/secondary piping or a method they call Boiler-Bypass to provide return water temperature protection. Slant Fin also says a three-way valve arrangement

The farther a heat-emitting unit is located from the boiler, the greater the length of the piping in the circuit. Although this factor causes problems in balancing the water supply among the various circuits, balancing can be achieved in a number of ways, including (1) balancing cocks, (2) proper pipe sizing, or (3) using a reverse-return system.

Hydronic radiant floor heating systems use a boiler or district heating to heat water and a pump to circulate the hot water in plastic pipes installed in a concrete slab. The pipes, embedded in the floor, carry heated water that conducts warmth to the surface of the floor, where it broadcasts heat …

It has three ports, one for the return water from the radiant zone, one for hot water from the boiler loop and a mixed port to supply the radiant zone. These valves can be manually set to maintain a fixed temperature or they can have an actuator that repositions the valve according to the load.

Combi system. This diagram illustrates how simple the heating system connected to a combi boiler is. No external pump, no tanks, no external expansion vessel, no motorised valves and in many cases item 6 is not needed either. (An automatic bypass valve is fitted inside most combi boilers …

2003/4/1 · The second three-way thermostatic valve bypasses hot water from the boiler outlet back into the return water flow whenever it senses the return temperature falling below its setpoint. This action limits the amount of heat delivered to the other three-way valve when necessary to prevent the distribution system from gulping down heat faster than the boiler can produce it.
