Home Owner Ventilation System Guide

Condensation and Mould

In Britain, condensation in houses is a problem, particularly where warm moist air is generated in areas like kitchens and bathrooms or by drying clothes over radiators. The moisture in the air gets left on surfaces in colder parts of the house, resulting in water running down the windows, leading to black mould on walls, ceilings, and in cupboards.

How can we reduce humidity levels:

• Adequate Heating: Air is like a sponge; the warmer it is, the more moisture it will hold.
• Adequate Insulation: Prevents cold surfaces for moisture to condense.
• Adequate Ventilation: Removes the excess moisture held in the warm air and provides fresh air, resulting in better indoor air quality.

Provide adequate ventilation

Traditional intermittent extract fans provide peaks of airflow. This means we are warming indoor air and then extracting it to outside, which is not energy efficient.

Instead, continuous running extract fans in bathrooms, kitchens, and utility rooms work with the natural air flow in the house, meaning you have a constant supply of fresh air which prevents germs multiplying and spreading, giving you a healthy home, but without the heat loss associated with intermittent fans.

What is it and why is it there?

The Vent-Axia Lo-Carbon Revive™ has been designed to meet all the requirements of the Building Regulations for bathrooms, kitchens, utility rooms, and toilets. It is designed to run all the time, which will keep your home fresh, healthy, and free from condensation.

What does it do?

The fan is designed to run continuously at a very low rate and boost when required. The low running rate means it has extremely low noise levels.

How will it help?

It will prevent the build-up of moisture in the house, remove steam and odours during cooking, and prevent black mould forming on the walls, behind cupboards, etc. It will also help stop the dampness that you can get in your cupboards and wardrobes, on your clothes and furnishings, caused by inadequate ventilation.

How do I control it?

The Lo-Carbon Revive runs all the time on 'Trickle' setting to ensure your home is ventilated at the correct level. Different methods are available for operating the boost speed, from simply being triggered by your light switch to an integral sensor which measures the levels of humidity and switches the fan to boost.

Does the unit require any maintenance?

Maintenance is minimal as the fan is designed to reduce the chance of dirt build-up. However, to clean the unit, the fan's power supply must be turned OFF first, then carefully wipe the front panel/grille with a damp cloth until clean.

DO NOT switch off the product

The fan is set to run continuously 24 hours a day, 7 days a week.

What are the running costs?

Its energy-efficient Lo-Carbon motor means a long life and low running costs. This means that, even though it is running continuously, you won't see a large electricity bill because it costs only 22p a week to run*.
