Wash Safely

Even when safety is top of mind, preventing hidden dangers in your water heater and at the tap probably isn’t. You need your home working to keep you and your loved ones safer.

Safe from Scalding

Handwashing is crucial to helping prevent the spread of disease. It’s important that your home’s water temperature is hot enough to kill germs but not so hot that it scalds.

Thermostatic Mixing Valve

The Right Temp Every Time

Water heaters need to be set at 140˚F or higher to kill bacteria but this could lead to scalding water at the tap. Our Resideo mixing valves allow you to set your water heater to a higher temperature to reduce the threat of bacteria growth, yet the mixing action helps prevent scalding at the tap.
