NB Common heat pumps are food refrigerators and air conditioners.
If you go to Sustainability Victoria’s pdf file ‘Benefits of Energy Smart Housing’ http://www.sustainability.vic.gov.au/resources/documents/eshousingmanualch01.pdf, there is information at the bottom of page 4 regarding the greenhouse impact of the heat pump vs a solar-boosted electric system.
The publication states that both the annual and lifecycle greenhouse impact of a heat-pump is substantially less than a solar-boosted electric heater!
Sean asks, why then did the Federal Government reduce the changeover rebate for heat-pumps to $1000 yet left the rebate at $1600 for less-efficient solar-boosted electric systems?
Sean tells us that GAS and solar-boosted GAS systems have a lesser impact but only if you have access to Natural Gas. The document doesn’t show the figures for solar-boosted LPG but the additional impact of LPG tank delivery/refill in regional areas outweighs the solar gain so they are not worth considering (cost much more to buy and operate than heat-pumps too).
Has haste/politics been the problem? The Green Loans and other sustainability incentives and rebates have been incredibly popular but it does seem that industry experts have either not been properly consulted or ignored due to the huge popularity of the Government schemes.
Do we need an open forum so questions can be asked and responses discussed, then Government can make adjustments where necessary and regain some credibility/integrity?
