*Registering does not lock you in to a purchase

As part of our work at the Queenstown Electrification Accelerator, we’re looking for different ways to make electrification easier and cheaper. One way we’re doing this is by harnessing the community's collective purchasing power to secure community discounts with suppliers. As always, the QEA remains completely independent, and does not earn any commission on sales - we just pass all the savings on to you.
Right now you can access around $1,000 off the retail price for products from Reclaim Energy, Daikin, Emerald, Stiebel Eltron and Black Diamond (see below for specs and prices). After you have registered your interest you will be contacted by the installer(s) of your chosen product(s). It's important to note that signalling your interest does not lock you into a purchase.
Some of the discounts are only available in the local Queenstown Lakes area, however some are available nationwide.
Current group discount products
The below costs are based on a standard LPG replacement. If you’re installing in a new build or replacing a different system, unless otherwise stated, discounted rates still apply and a tailored quote will be provided after a site visit. All prices include GST.
All-in-One Systems
Also known as integrated systems, all-in-one systems combine the heat pump and hot water cylinder into a single unit. Most all-in-one systems are designed to be outdoors, however some (such as Stiebel Eltron's option below) can be installed inside as well. They tend to cheaper than split systems.

Split Systems
Split systems separate the heat pump from the hot water cylinder, which offers more flexibility in layout. Generally, compared to all-in-one systems, split systems are known to be more efficient, be better in cold climates, and have higher recovery rates (which means they heat water faster).
