Why Ariston S 3.5 COM PL Water Heater water is not hot enough?
- JJason JenningsAug 9, 2025
If the water from your Ariston Water Heater is not hot enough, it could be due to several reasons. First, too much water might be flowing through the heater; try reducing the flow rate via the outlet tap. A reduction in the ambient temperature may also be the reason; try switching to a higher temperature setting. Also, check if the mains stop valve is fully open and that there are no other restrictions in the supply line, as the water pressure may be below 100 kPa. If none of these solve the issue, there may be an electrical malfunction, in that case have the heater unit checked by a qualified electrician or contact your local authorised distributor.
