Vasco Repair Service in Werrington

Why does my Vasco radiator stay cold when the heating is on?

A cold Vasco radiator when the heating is on may indicate a stuck valve or an issue with the valve insert. Do not attempt to disassemble or manipulate valve components yourself. Contact a qualified heating engineer to inspect and repair the valve mechanism.

Why does my Vasco radiator with blower make noise after turning off?

This is normal operation. Vasco radiators with blower units have a post-ventilation cycle that continues briefly after heating stops. The blower will stop automatically once this cycle completes.

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.

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.

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 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.

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.

What happens if the supply and return pipes are connected the wrong way round?

If the supply and return pipes are reversed, the radiator will not heat properly or may only warm partially. To identify the correct connections, increase the thermostat setting and feel which pipe heats up first—this is the supply (flow) pipe.

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.

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.
