Non-domestic showers

Non-domestic showers refer specifically to showers used in commercial and hospitality settings, such as hotels, gymnasiums, student accommodations, hospitals and office spaces.

To be energy efficient, a shower should use the least amount of water and energy while maintaining a high-quality user experience. The ETL criteria for showers include consideration of flow rate, pressure independency and spray coverage as indicators of efficiency.

For end-users, particularly those with high shower usage, the economic and environmental benefits are substantial. By investing in ETL-listed showers, they can reduce their water and heating bills by adopting high-efficiency shower systems that regulate flow and temperature effectively.  

The ETL's inclusion of other related technologies, such as wastewater heat recovery systems, presents alignment opportunities for delivering comprehensive energy-saving solutions to end-users. By capturing waste heat from shower water to preheat incoming water, end-users can further enhance their energy efficiency and reduce operational costs.
