Define a y plan central heating system?

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.

Do you need to shut water off at water heater before shutting main water off?

Yes, it’s a good practice to shut off the water supply at the water heater before turning off the main water supply. This helps prevent the water heater from draining and potentially damaging its components. Additionally, it reduces the risk of sediment buildup and helps maintain the water temperature in the tank until the main supply is restored. Always ensure the water heater is turned off before performing maintenance or repairs.
