Heat Recovery Ventilation system (HRVS)

Today’s homes are built with extra insulation to keep warm air in and reduce energy costs. This however leaves very little opportunity for your home to be naturally ventilated.

Ventilation establishes a good level of indoor air quality and an environment that is free from condensation, odours and indoor pollutants caused by cooking, washing and day to day living. It is therefore important that you have adequate ventilation in your home.

Having the heat recovery ventilation unit installed in your apartment

will not only ensure that your property has good indoor air quality,

it will protect the fabric of your apartment from condensation and mould, thus resulting in a healthier living environment. 

How do I operate the unit?

At installation your unit will have been set to run continuously to a level that will adequately ventilate your apartment for the majority of the day.

However, there will be occasions when the humidity/ moisture levels in your home will rise; this is usually due to activities such as cooking and bathing or showering. During these times your unit has the functionality to increase its extract rates via a boost mode, and remove the excess moisture.

There is a switch in your kitchen and the switch next to your bathroom light.

Turn this on to boost when cooking or showering or when you need extra air circulation. Keep on boost for at least 10 minutes after a shower


What maintenance is required?

The filters (located on the front of the unit) need to be cleaned every few months

and replaced every 6-12 months. (Maybe change every 3 months if no cleaning is done) The heat exchanger and motor should also be checked every 12 months. 

For replacement filters contact Paul for the price for supply only or supply and install.
