HEAT RECOVERY VENTILATION SYSTEM (HRVS) 


The Heat Recovery Ventilation System (HRVS) - 'ComfoAir 350' is manufactured by Zehnder (in Germany), imported into New Zealand by Fantech and is distributed by Carters. This is the second house in New Zeland to adopt this system.

The 'Fantech' HRVS has been considered throughout the detailing for construction as can be seen in photographic record from the pouring of the concrete floor slabs.  The ducting (grey) is woven through the structure to remain concealed, and to service all rooms within the house.  The outlets are recognisable at this stage of the construction process, as large grey bulbs that sit below the ceiling line.  These will be trimmed to accommodate the vents that will be fitted later.

The grey ribbed ducting is fitted into the framed walls and ceilings
The grey bulb terminating at  the end of the ducts will have outlet grilles fitted later in the build process.


The ceilings have been framed, and  linings have been installed allowing for hatches in the ceiling to access the HRVS units for future servicing and maintenance.






Now the house interior has been lined, the duct fittings are installed for use. The duct is located alongside to the left of the light in this following picture, and on the wall above the kitchen cabinetry in the picture after.

    Luckily I installed new ducted system at my new house in Auckland. This system blows heated or cooled air throughout the house through discreetly installed grill vents. Guys from Fonko heating and cooling service installed it in the short period of time at affordable price. At least in my house I can enjoy the perfect temperature all year round.

    HRV or ERV for Lower Hutt home?

    Hi,
    I came to this blog, while doing some research about installing a central ducted heating system with ventilation, primarily to help with my sons hay fever allergies, for my single story single glazed 1998 home in Lower Hutt.

    It would be great to get your recommendation for Lower Hutt region houses - Heat Recovery Ventilation or Energy Recovery Ventilation.

    Thanks and Regards,

    Ren
