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

A blinking green LED on a Vasco E-Volve controller indicates frost protection mode is active or open window detection has been triggered. Close any open windows or doors and the radiator will resume normal operation once the temperature stabilises.

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 the Er error mean on a Vasco electric radiator?

The Er error on a Vasco electric radiator indicates that the room temperature sensor is defective or disconnected. Switch off and unplug the radiator from the mains before any inspection. If the error persists, contact a qualified heating engineer for sensor replacement.

Why is my Vasco electric radiator not heating even though the remote shows it's cold?

The RF remote temperature reading is indicative only and may differ from the actual temperature at the radiator's sensor, located at the bottom rear of the unit. Cold draughts from open doors or windows can affect sensor readings. Consider disabling open window detection or calibrating the temperature sensor.

Why is my Vasco radiator making ticking or gurgling noises?

Ticking or gurgling noises in a Vasco radiator are typically caused by air bubbles trapped in the heating system. Bleed the radiator using a radiator key at the bleed valve until water flows consistently. If noises persist after bleeding, there may be a leak or expansion vessel issue. Contact a qualified heating engineer for inspection.

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.

Why should I avoid installing thermostatic valves on radiators in the same room as my room thermostat?

Thermostatic valves sense temperature close to the radiator and close when the target is reached. However, the room thermostat positioned elsewhere may still register a cooler temperature, causing the boiler to continue running. This conflict can cause the heating system to malfunction or work inefficiently.

Do I still need to place radiators under windows?

In older, poorly insulated homes, placing radiators under windows remains advisable to combat cold draughts from single or poor-quality glazing. However, in well-insulated homes built within the last 20 years, radiators can be positioned anywhere due to improved glazing and insulation.

What is a Vasco ventilo-convector?

A ventilo-convector is a heating unit that warms air through a heat exchanger. Cold air is drawn in, heated, and then rises as warm air to circulate throughout the room. Unlike traditional radiators that rely on radiant heat, convectors actively move air for faster, more even temperature distribution.

Can I paint my Vasco radiator?

While possible, painting radiators requires thorough preparation including cleaning, sanding, and stripping the old finish. Skipping these steps results in a radiator that does not perform properly. Use heat-resistant radiator paint only.
