The reason this system is called a 'Y' plan is because of the shape of the 3 port valve.
Heated water from the boiler is diverted to the hot water coil or the radiators depending on which service the programmer is asking for and which thermostat is calling for heat. The 3 port valve also acts as a switch to turn on heating system components. Therefore you need a certain sequence of switches to work in order for the system to operate. For example with radiators:
1. The programmer reaches a timed period where the radiators require heat.
2. The programmer activates a live supply to the room thermostat.
3. If the room is cold then the thermostat will switch this live supply to the motor in the three port valve.
4. The three port valve will motor over to open the radiator water outlet. (Takes about 10 seconds)
5. When the valve opens it switches a separate live supply which feeds the boiler and pump.
6. Boiler and pump receive live supply and operate. Soon you should feel some hot water in your radiators.
The three port valve has 2 live supplies to motor it one way or the other depending on what the system is calling for: hot water or hot radiators or both.
What else can I help you with?
Can radiant heating replace central heating systems?
Yes, radiant heating can replace central heating systems, as it provides efficient and even heating by warming surfaces and objects in a room rather than just the air. This system can be particularly beneficial in areas with high ceilings or in open-plan spaces. However, the feasibility of replacing central heating with radiant heating depends on factors such as the existing infrastructure, installation costs, and specific heating needs of the building. It's essential to evaluate these factors before making a decision.

How can I install a hot water floor heating system in my home?
To install a hot water floor heating system in your home, you will need to first determine the type of system that best suits your needs, such as hydronic or electric. Next, you will need to plan the layout of the system, including the location of the tubing or heating elements under the floor. Then, you will need to install the tubing or heating elements, connect them to a boiler or water heater, and fill the system with water. Finally, you will need to test the system to ensure it is working properly and make any necessary adjustments. It is recommended to consult with a professional for guidance and assistance during the installation process.
