Vasco Repair Service

Why won't my Vasco RF thermostat pair with the electric radiator?

The RF remote control and RF receiver are not pre-paired from the factory and must be connected following the instructions in the thermostat manual. Ensure both devices have power, position them close together during pairing, and follow each step carefully. If pairing fails repeatedly, press and hold the MEMO button on the RF receiver for more than 10 seconds to cancel and retry the pairing process.

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 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.

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 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.

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.

How do I clean a Vasco radiator?

Dust radiators regularly using a vacuum cleaner or damp cloth. For ladder-style or vertical designer radiators, use a long feather duster to reach between the tubes. Convective heating units collect dust particularly easily and benefit from regular attention.

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.

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.

How does a Vasco infrared panel work?

Vasco infrared panels heat objects and people directly rather than warming the air. An electrical element heats the panel surface, which emits invisible infrared radiation similar to the warmth of sunlight. This radiation is absorbed by walls, furniture, and people, creating even and comfortable warmth without air circulation.
