Frequently Asked Questions - EWH-80VM Vivax
How do I set the temperature on my Vivax EWH-80VM boiler?
Turn the thermostat dial located on the front panel. The range is from 30°C to 75°C. For normal use, set between 55°C and 65°C to prevent scale buildup.
What does the pressure relief valve do and how to test it?
The pressure relief valve releases excess pressure to prevent tank rupture. Test it every 6 months by lifting the lever briefly; water should flow and stop when released. If not, replace it.
How often should I replace the anode rod?
Inspect the magnesium anode rod yearly and replace every 2-3 years or when it's less than 10 mm thick. This prevents corrosion of the tank.
Why is my boiler leaking water from the bottom?
A leak could be due to a faulty pressure relief valve, loose drain valve, or a corroded tank. Check the connections first; if the tank itself leaks, it may need replacement.
Can I install the boiler horizontally?
Yes, the EWH-80VM supports both horizontal and vertical wall mounting. Ensure the drain valve is at the lowest point for proper draining.
How do I drain the water heater?
Turn off power and water supply. Attach a hose to the drain valve, open a hot water tap, then open the drain valve. Flush until clean water runs out.
What size water heater do I need for a family of 4?
An 80-liter tank (like the EWH-80VM) is suitable for 2-3 consecutive showers. For 4 people, consider a larger model or manage usage.
The water is not heating; what could be wrong?
Check the circuit breaker and thermostat setting. If both are fine, the heating element may be faulty. Test with a multimeter or call a technician.
How do I descale the heating element?
Descale every 1-2 years depending on water hardness. Drain the tank, remove the element, and soak in vinegar or descaling solution for several hours, then scrub gently.
Can I use an extension cord?
No, never use an extension cord with a water heater. It must be directly connected to a dedicated power outlet with proper grounding to avoid fire risk.
