How to drain the boiler

This, of course, means that before doing anything you should read the boiler manual and ensure that you are familiar with all the parts of your boiler and what you are doing.
We will take you through a step-by-step on how to drain your Worcester Bosch Combi boiler.
- Ensure that the boiler is switched off and is no longer connected to the power supply. This is the first and one of the most important steps. The boiler must not be turned on.
- Give the water time to cool down, it is important to ensure that the water is cool before anything is drained so that the people that are working on it are not at risk of being harmed.
- After you have given the water time to cool down, you must connect a hose tightly and securely to the drainage valve. This is generally at the lowest point of the lowest radiator in the house or property in question. If you are unsure of this then you should consult a gas safe engineer or a professional.
- Once the hose is safely attached, the valve on the radiator that the hose is attached to is opened and the water will begin to drain from the system.
- This process of drainage can be quicker by way of opening the vents at the top of each radiator, however, you need to remember that you must know what you are doing and have the skills to carry out these steps, to avoid any damage or destruction of your heating and boiler.
- Once the water has all gone and you have successfully drained it, you can close the bleed valve, and the process is complete.
So these are the basic steps of draining a Worcester Bosch Combi Boiler, however, as we alluded to at the start, all boiler systems and different boiler types will have different specifications. So, ensure that you are sufficiently skilled, following the correct manual for your specific boiler and performing all the steps in a safe, controlled manner.
