Vasco Appliance Repair in St David's

Why does my Vasco electric radiator keep heating when the set temperature has been reached?

The radiator's temperature sensor is located at the bottom rear of the unit. If you have underfloor heating, this can warm the sensor area more than the rest of the room, causing the radiator to continue heating despite the RF remote showing the target temperature has been reached. Consider recalibrating the temperature sensor through the settings menu to compensate for this difference.

How can I check if my Vasco E-Volve WiFi module is connected to the temperature sensor?

To verify the connection between your E-Volve WiFi module and temperature sensor, open the Vasco Climate Control app and navigate to Settings, then Setup, then E-Volve WiFi. Select your room and open Room Settings to check the sensor connection status. If the sensor is not detected, ensure it has fresh batteries and is positioned within Bluetooth range of the WiFi module.

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 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 does my Vasco radiator not heat efficiently when installed close to the floor or ceiling?

Vasco radiators require adequate clearance above and below for proper air circulation. Cold air is drawn from the floor and rises as warm air exits above the radiator. Insufficient space restricts this natural convection process, reducing heating efficiency. Maintain approximately 10 to 15 centimetres of clearance both beneath and above the radiator where possible.

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.

Should I turn off underfloor heating when I'm not at home?

No, do not turn underfloor heating off completely when away. Set the thermostat to 14°C for extended absences. Underfloor heating takes on average one to one-and-a-half hours to change temperature by 1°C, so it responds slowly to adjustments.

How do I control a Vasco electric radiator with WiFi?

The E-Volve WiFi module connects your electric radiator to your home WiFi network, enabling control via the Vasco Climate Control app. The module communicates via Bluetooth with a temperature sensor placed in the same room, allowing you to set temperatures individually for each room from anywhere.

Why is ventilation filter maintenance important?

Filters remove unhealthy substances from outdoor air including pollen, dust, and contaminants. They also prevent contamination of the air ducts, which can otherwise become a breeding ground for bacteria.

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.
