It is generally recommended to turn off the shut-off valves instead of the angle valves when shutting off water supply to a fixture or appliance. Shut-off valves are designed to control the flow of water to specific fixtures and are easier to operate, making them a more convenient option for regular use. Angle valves, on the other hand, are typically used for installation purposes and may not be as accessible or easy to operate. Additionally, shutting off the shut-off valves can help prevent wear and tear on the angle valves, ensuring they remain in good working condition. **

The pipes may still be warm even though the heating is turned off because residual heat from the hot water circulating through the pipes can take some time to dissipate. Additionally, if the pipes are located near a warm area of the house or are well-insulated, they may retain heat for longer periods of time. It is also possible that there is a mechanical issue with the heating system causing it to continue to generate heat even when it is supposed to be off. **

The decision to turn the water boiler off or on depends on the specific circumstances. If the boiler is not in use and there is no need for hot water, it is generally more energy-efficient to turn it off to save electricity. However, if hot water is needed regularly or if the boiler is used for heating, it may be more practical to keep it on to ensure a constant supply of hot water. It's important to consider both energy efficiency and practicality when deciding whether to turn the water boiler off or on. **
