Build Expo LHZ Heater Winner

Judy, an Architectural Designer is now the proud owner of an LHZ heater after attending the Build Expo held in Auckland in July.

HRV's Commercial Sales Manager, Rhonda Taylor, said "Judy was overwhelmed  to receive her prize. The room the heater went into was very cold at the time of our arrival. After half an hour of switching it on, we went into the room and she was delighted to feel how cozy it was. She loved the design of the heater - calling it "very posh looking".

A very deserving winner!

Builders Tips:

Why builders should discuss ventilation with their clients

1. New homes are being sealed up really tightly with new requirements for insulation, building wrap and double glazing.
   
2. The building code requires at least 0.35 air changes per hour or at least one complete air change every 3 hours.
   
3. The G4 code states that this shall be achieved by providing a net openable area of windows of other openings of no less than 5 % of the floor area.
   
4. Home owners are creating anything up to 20 or 30 liters of moisture per day by showering, cooking, breathing, etc.
   
5. A Californian study showed that less than 17% of their home owners open more than one window on a regular basis for ventilation. We believe that NZ figures are very similar.
   
6. Because we are not ventilating our homes on a regular basis high levels of moisture are retained within the building envelope leading to mould and other problems.
   
7. As a builder your reputation is based on the functionality of your homes which can be drastically affected by excess moisture (crying windows).
   
8. Double glazing has the effect of raising the temperature of the internal glass and thus may reduce the amount of condensation on this area. However the actual level of moisture is likely to have been increased and the condensation is now more likely to appear on the aluminium unless the thermally broken suite is used.
