In order to prevent bacterial growth, hot water tanks are required to keep water at a temperature of 140 degrees celsius. However, water exiting the valve is not permitted to be over 120 degrees celsius. As a result, buildings are required to have a domestic hot water mixing valve to facilitate this quick cooling process. 

​

What seems like a small process can lead to big problems if not handled correctly. The risk of bacterial growth or overheated water exiting the valve is very serious and poses as a major health risk. Jermark has over 35 years of experience maintaining the monitoring domestic hot water mixing valves, and we can give you peace of mind that your tenants' hot water tanks will be running smoothly.
