Heat Recovery Fans
Heat Recovery Fan Single Room Heat Recovery is a through-the-wall ventilation unit designed for a one-room installation, such as a kitchen or bathroom. It works in the same way as the whole house method, by extracting the moisture-laden air and supplying the fresh, tempered air that has been warmed by the heat exchange cell. This method of ventilation is ideal for replacing old and inefficient extract fans, by providing a much more energy-efficient alternative.
Lo-Carbon Tempra Single Room Heat Recovery Unit
Features & Benefits Fits in 100mm diameter hole – ideal for refurbishments 74% heat recovery Reduces your carbon footprint Choice of control options Suitable for refurbishment Summer setting Helps prevent noise ingress Continuous running or intermittent extract Through The Wall Mounted Heat Recovery Unit The Vent-Axia Lo-Carbon Tempra is designed to fit in 100mm diameter hole and is suitable for refurbishment, kitchen, bathroom, toilet or utility applications. The unit meets the performance requirements for intermittent extract fans under the Building Regulations Part F (Table 1.1a) and also for continuous products. Installed in all wet areas, the Tempra is classed as a wholehouse ventilation system and therefore is only required to move the amount of air as laid down in table 5.1a of Document F. Maximum wall thickness 318mm The manual summer setting allows the unit to be set to extract only, helping to prevent a dwelling becoming too warm in hot summer conditions. Performance Tempra can be set to run continuously at 6l/ s or 9l/s, boosting up to 13l/s, recovering heat from extracted air and returning it to the dwelling. The unique, compact heat exchanger has a temperature efficiency up to 70%, saving energy and reducing your carbon footprint. For intermittent extract the Tempra is set to 15l/s. The Lo-Watt ECDC motor with twin impellors consumes as little as 3.4 Watts on trickle rate and runs almost noiselessly at only 20dB(A). Typical Installation
The unique heat exchanger design allows the Tempra to be fitted in a 100mm diameter hole, allowing it to replace standard 100mm extract fans while giving all the benefits of heat recovery.
