Whole House Heat Recovery System
What is it and why is it there?
The energiSava 250 is a centralised heat recovery fan unit that continuously removes stale, moist air from your bathroom, kitchen, WC and replaces it with clean fresh tempered air through circular valves mounted in your ceiling and into your living room areas.
How will it help?
It will prevent the build up of moisture in the house, reduce steam/condensation and odours during bathing and cooking, which contribute to black mould forming on the walls, behind cupboards etc.
It will also help minimise the dampness that you can get in your cupboards and wardrobes, on your clothes and furnishings, caused by poor ventilation.
It provides continuous, all year round ideal indoor air quality.
How do I control it?
The system operates continuously 24 hours a day at a low rate known as ‘trickle’, to ensure your home is ventilated at the appropriate level. You can send the system into a higher rate called ‘boost’ by utilising the switch live. The switch live is an automatic function, sending the unit to boost when the bathroom or kitchen light is on.
Summer bypass
This helps to reduce the air temperature coming into the dwelling during the warmer periods. It is an automatic function and operates when the supply air temperature to the property is above 25ºC.
