POU heating systems, or Point of Use heating systems, are designed to provide hot water directly at the location where it is needed, such as sinks or showers. This eliminates the need for long pipe runs from a central water heater, reducing heat loss and improving efficiency. These systems can be electric or gas-powered and are often compact, making them suitable for small spaces. POU heaters are ideal for homes, offices, or any setting where hot water demand is localized, ensuring quick access to hot water without delays.
