Econergy selected for "Building Boxes" Project

15th December 2014

Building Boxes is an Eco Home Build project being carried out by Writer Michele Powles and her husband James Winton.  The project is interesting from several angles. Not least the practical energy efficiency and passive features built into the house without blowing out the budget.   

Michele and James have chosen the Econergy water heater for its high efficiency and ability to fit into a house design that involves some distance between the outdoor unit and the storage cylinder.  They also liked the fact that Econergy was made and supported locally.

To keep updated on the project you can follow their blog here:

Econergy wins Mega Efficiency Award at 2014 National Sustainable Business Awards

 19th November 2014

Econergy has won the Mega efficiency Impact Award at the NZI National Sustainable Business Network Awards held at Shed 10 on Auckland’s waterfront on 18 November. 

Econergy impressed the judges with proof that new generation heat pumps are changing the wasteful industry of hot water cylinders, backing up their application with impressive results around energy savings for everyday households. The judges liked the fact that Econergy systems can be retrofitted onto current hot water systems: this shows they are providing a solution which is tailored to the NZ market. The judges believe there is huge potential for technology like this to improve energy efficiency, and would like to see solutions like this becoming the norm.

Econergy Managing Director, David Senn said “We are blown away by this award, especially given stiff competition on the night from several publically listed companies.  We take it as tacit endorsement that our growing customer base is saving a massive chunk of energy and carbon emissions with their heat pump hot water system installations.  Receiving this recognition will help us to scale the project together with its economic and environmental benefits”

Homeowners grab $575 heat pump water heater grants
15th August 2011

Press Release – Econergy Limited

Demand for government heat pump water heater grants has exceeded expectations, according to Econergy Limited, manufacturer of the Consumer award winning HP4000LT heat pump water heater.

Homeowners have been able to access a $575 EECA Energywise grant for installing an Econergy heat pump water heater in their homes since February of this year.

“Demand for the grants has exceeded expectations” says Econergy Managing Director David Senn, having used their 2010/11 allocation up by 20th July. New allocations have now been made by EECA and are available, but only on a first-in first served basis. “At the current rate of uptake, we are expecting this fiscal year’s allocation to be used up by November of this year, so would encourage interested parties to make expressions of interest at an early stage”.

Heat pump water heaters work by moving heat from ambient air into a hot water cylinder, allowing efficiencies over 300% to be achieved compared with the standard immersion element which is only 100% efficient. Heat Pump Water Heaters have the potential to allow widespread energy savings & reduction in the national grid load, being retrofit table to the majority of New Zealand homes.

18th December 2009

Econergy Managing Director David Senn was ecstatic when he learned from Consumer NZ that his HP4000LT heat pump water heater was awarded best product of the year in the home and DIY products category.

“This is a great win for New Zealand” says David, whose product received a consumer recommendation for the best heat pump water heater earlier this year, beating world leading brands manufactured in Australia and Germany.

Four years ago the Econergy heat pump water heater was little more than a dream, when David was still building a prototype system at his friend's workshop in Ardmore on weekends. Weekdays he worked as a consultant saving pennies for launch of his startup company.

“Learning we won best Home and DIY product of the year has been a great boost for our small team” says David. “This is great finish to a year of dynamic growth”.

Consumer NZ's Bill Whitely said...

“The Econergy HP4000LT was the star of our heat-pump water heater test, blitzing its competitors. These water heaters work by using warmth from outside air to heat your hot water. Our test found the Econergy, a locally designed and made product, was at least three times more efficient than a standard electric cylinder. It's on a par with solar-power in terms of energy savings - and is likely to out-perform solar in less sunny parts of the country”.
