Vasco Appliance Repair in Longlevens

Why is my Vasco radiator making a hissing or rushing water sound?

A hissing or rushing water sound from a Vasco radiator typically indicates excessive water flow at the valve, often caused by high system pressure or debris partially blocking the valve. The heating system may require water-side balancing to ensure proper flow distribution. Contact a qualified heating engineer to diagnose and resolve the issue.

What does a blinking orange LED mean on a Vasco E-Volve controller?

A blinking orange LED on a Vasco E-Volve controller indicates that manual override is active via the MEMO button. This temporarily overrides the programmed schedule. Press the MEMO button again to cancel the override.

What does a blinking red LED mean on a Vasco E-Volve controller?

A blinking red LED on a Vasco E-Volve controller indicates that boost mode is active, providing rapid heating to 30°C for one hour. The radiator will automatically exit boost mode after the set duration, or you can cancel it manually by pressing the boost button again.

Why does my circuit breaker trip when my Vasco electric radiator turns on?

Vasco electric radiators are double-insulated (Class II) and must be connected without an earth wire. If the radiator is wired with an earth connection, it will trip the circuit breaker. Do not attempt to check or modify the wiring yourself. A qualified electrician must disconnect the earth wire to resolve this installation issue.

Why won't my Vasco E-Volve WiFi module connect to the internet?

The Vasco E-Volve WiFi module only supports 2.4 GHz networks. Many modern routers and WiFi extenders operate on 5 GHz, which is incompatible. Check your router settings to ensure the 2.4 GHz band is enabled and move the module closer to the router during initial setup.

How do I calculate the correct heat output for a Vasco radiator?

Use the formula: square metres × watts per square metre = required heat output. A radiator's heat delivery is expressed in watts, and the required output depends on the room type, desired temperature, insulation level, and heating system type.

How do I bleed a Vasco radiator?

Turn all radiators to their highest setting and let them run for at least fifteen minutes. Switch off the central heating and wait at least ten minutes for the radiators to cool. Starting with the radiator closest to the boiler, close the radiator tap, place a container under the bleed valve, and turn the valve anticlockwise with a radiator key or screwdriver until water flows out instead of air. Close the valve and repeat for each radiator, working from lower to upper floors.

What is the ideal temperature for Vasco underfloor heating?

Set underfloor heating surface temperatures differently for each room based on use. Bathrooms are typically most comfortable with floor surface temperatures around 32°C, while living areas work well at around 28°C. These are floor surface settings, not room air temperatures. There is no single perfect temperature—adjust based on personal comfort.

Why is my Vasco radiator cold at the top but warm at the bottom?

This is typically caused by air trapped in the radiator, preventing hot water from circulating fully. Bleeding the radiator using a radiator key or screwdriver at the bleed valve will release the trapped air and restore proper heating.

What is the difference between the Vasco Boost and Boost H ventilation systems?

The standard Vasco Boost recovers heat from exhaust air to warm incoming fresh air. The Boost H includes an enthalpy heat exchanger that recovers both heat and moisture from the outgoing air, providing improved indoor comfort during the heating season by maintaining better humidity levels.
