Questions and answers
Can I set the hot water temperature above 60C?
The maximum flow temperature for the Worcester Greenstar 4000 can be adjusted between 30°C and 82°C. However, if the flow temperature is set above 65°C, it is advisable to fit a thermostatic mixing valve (TMV) to prevent scalding. Therefore, you can set the hot water temperature above 60°C, but safety precautions should be considered.
