Home Ventilation

Home Ventilation

Today's stringent building regulations and general awareness for energy conservation means that our homes are now better sealed than ever. Double glazing, draft excluders and thicker roof insulation all help to reduce the rate at which heat escapes from our homes, yet as a consequence very little fresh air can enter, and the air within our homes can become stale.

Opening windows around the house can help, but this is not a controllable means of ventilation. Heat is quickly lost, and open windows can represent a security risk.

In certain areas, noise pollution from nearby roads, airports and schools is a good reason in itself for doors and windows to be kept firmly closed.

A home heat recovery ventilation (HRV) system is the solution.

Heat-recovery ventilation

home ventilation

Fresh, outside air is drawn into the HRV unit, where it is filtered before being delivered into various areas within the home via concealed ducting.  At the same time, stale air is continually being removed from other areas within the home, which is then exhausted to outside.


heat recovery mode

The simple concept of the above home ventilation system is fine when the outdoor air temperature is exactly the same temperature you like to keep your home at, but it wouldn't be desireable to deliver outside air at say -5°C into the home, would it?

This is where the efficient heat recovery technology steps in.

The stale, but warm air being extracted from the home passes through a heat exchanger within the HRV unit which collects up to 80% of its heat energy before exhausting it to outside.  The fresh air being delivered into the home then passes through the same warm heat exchanger, collecting the recovered heat as it does so.

As a consequence, most of the expensive heat that you've created in your home is retained, but the stale air in which it existed is removed.


intelligent heat recovery controls

The intelligent electronic controls of the HRV unit can automatically monitor the temperature of the outside air, to determine whether or not the fresh air being introduced into the home needs to be warmed by the heat exchanger.

If the outside air is cooler than 23°C, the fresh air being drawin in will automatically be routed through the heat exchanger before being delivered into the rooms.  If the outside air temperature is 23°C or above, the incoming air automatically bypasses the heat exchanger, in turn providing free cooling to the home in the summer.
