Hello there, I'm an expert in home heating systems and I'm here to help you with your query. It's a common concern to wonder if it's possible to use a heating system when the water supply is interrupted. Let's delve into the details.

Firstly, it's essential to understand the different types of heating systems and how they interact with the water supply. There are several types of heating systems, including central heating, which is commonly used in residential and commercial buildings. Central heating systems can be powered by various sources such as gas, oil, or electricity, and they typically consist of a boiler, radiators, and a hot water storage tank.

The cold water storage tank you mentioned is a crucial component in many homes. It's usually located in the attic or loft and serves as a reservoir for cold water used throughout the house. This tank is connected to the main water supply and is filled when the water supply is available.

Now, let's address the scenario where the water supply is cut off. If your cold water storage tank is full, it means you have a reserve of water that can still be used for certain purposes. However, it's important to note that this water is not replenished until the water supply is restored.

In terms of running your central heating, if your heating system uses a boiler that is separate from the water supply for the cold water tank, it should be safe to continue using it. The boiler heats the water that circulates through the radiators, and this process does not necessarily require a continuous supply of cold water. The water in the system is recirculated and does not get used up in the way that tap water does.

However, when it comes to using hot water, caution is advised. If the water supply is off, the cold water tank cannot be refilled, which means the pressure in the system could drop. This drop in pressure can affect the operation of your boiler and the delivery of hot water to your taps. Additionally, without a fresh supply of cold water, the water in the tank may not be as clean, which could be a concern if you're using it for washing or cooking.

It's also worth mentioning that some heating systems have safety features that prevent them from operating if the water pressure is too low. In such cases, the heating system would not function until the water supply is restored and the pressure is back to normal.

In conclusion, while it may be technically possible to run your central heating with a full cold water storage tank when the water supply is off, it's not advisable to use hot water under these circumstances. It's always best to check your specific heating system's manual or consult with a professional to understand the safest course of action. Remember, safety and the proper functioning of your heating system should always be your top priorities.
