ECO HOUSE POWER READINGS & SAVINGS

This house uses a fair bit of power – aircon on in the home office, the washing machine and dishwasher are used every day, and people like to shower. The daily power cost was averaging $8.84/day. A decision was made to make the place more eco-friendly and reap the long-term benefits, and the following was installed:

• 7k PV panels
• 4.5k Hotwater heat pump and tank
• LED lighting

Additionally, the house was connected to electricity through Electric Kiwi who offer the free “hour of power” (more details on the Energy Solutions page) – the washing machine and dishwasher are on timers and set to come on during the hour of power. The Hotwater heatpump was also set on a timer to come on at 8:30am when the PV panels are generating electricity. The result? Daily power charge is now averaging $3.90/day. That is a saving of nearly $5/day, a total of $1722 a year, meaning in 6.6 years the investment would have paid for itself, and everything beyond that is money saved.
