Heat Recovery Systems

Heat recovery systems take the heat out of the air that is being expelled from your house and use it to warm the new air entering your house.

Why the need to ventilate your home?

These days as we try to be more energy conscious we build for ourselves lighter, better insulated and sometimes quite unbreathable homes.

Normal family life generates considerable moisture from such activities as cooking: 3 litres per day, showers and baths: 1.5 litres per day, body respiration and perspiration 1-2 litres per day per person etc. (BRANZ). With this level of moisture generation combined with current tight home construction, relative humidity levels (airborne moisture) increase dramatically. This causes problem condensation and produces a home that ultimately becomes harder to heat and makes insulation less effective.

Dry-Matic

To provide a cost effective solution to condensation problems Smooth-Air have designed, developed and manufactured the Dry-Matic range in New Zealand for New Zealand conditions.

Dry-Matic Ventilation Systems are ideal for

• Existing Homes
• New Homes
• Rental Accommodation

Heat Transfer – Heat Humper

Use the excess capacity of your heat source to warm other rooms in your home. An average size lounge requires 2-4 kW of heating, yet heating appliances such as log burners* can generate 10-20kw. That’s 5 times the amount of heat required for a lounge room. This leaves an excess of 8-16 kW of heat available to warm other rooms in your home. Air trapped at ceiling level can reach temperatures in excess of 30°C so, why not …

…hump that heat to where it’s needed!
