How to Drain Hot Water Boiler?

Answer

Before draining the boiler, you should first turn off the boiler and the water supply, then let the boiler cool down before attempting to drain the water. Locate the boiler drain valve, place a container underneath the boiler drain, then open both this valve and the valve of one of the radiators in the house, preferably one on the topmost floor. The water in the boiler should then drain into the container, allowing you to perform any maintenance that you need to.
