A downflow heater is a compact electric heater typically installed on walls, often in bathrooms or small spaces. It works by drawing in cool air, heating it, and directing the warm air downwards to provide quick, localized heating.

Yes, downflow heaters are commonly used in bathrooms in the UK because they provide instant heat in small areas. They are safe to use in bathroom zones if installed in compliance with IP (Ingress Protection) ratings and UK electrical regulations.

Downflow heaters are designed to provide short bursts of heat in small spaces, which can be energy-efficient if used properly. Many models come with features like timers and thermostats to help minimize energy consumption.

While some homeowners may install downflow heaters themselves, it is highly recommended to have them installed by a qualified electrician, especially when installing in a bathroom to comply with UK electrical safety standards.

The running costs depend on the power rating of the heater (typically between 1kW to 2kW) and how often it is used. For occasional use in a small space, such as a bathroom, the cost is generally low, but it’s important to monitor usage to avoid high energy bills.
