Vasco Appliance Repair in Davenport & Cale Green

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 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.

Why is the boost function not working on my Vasco electric radiator?

The boost function may not work if the thermostat is not connected to the blower unit, open window detection is enabled, the target temperature has been reached, or the radiator lacks power. Check these factors and disable open window detection if needed. You can also activate boost directly on the blower unit.

What does Error 12 mean on a Vasco electric radiator thermostat?

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.

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.

Are Vasco fan convectors noisy?

Modern Vasco fan convectors operate very quietly with adjustable fan speed settings. At lower speeds, the sound is barely perceptible, making them suitable for bedrooms and living spaces where noise levels are a concern.

Can I use underfloor heating for cooling in summer?

Yes, if your heat pump includes a cooling function, cold water can run through the underfloor heating pipes to cool your home. A water temperature of around 18°C is ideal for cooling. Ensure the floor surface temperature remains above the dew point to prevent condensation forming on the floor.

Why does my Vasco radiator make ticking or gurgling noises?

These sounds indicate air bubbles trapped in the heating system. While not immediately harmful, trapped air should be removed by bleeding the radiators to prevent oxidation and corrosion of the pipes over time.
