Using a heat pump to heat hot water

Posted on Dec 12, 2012

Is your power bill killing you?

Installing an Econergy heat pump water heater could help. We talk to managing director David Senn to find out more.

How does the Econergy® water heater work?

Manufactured in New Zealand for South Island weather conditions, the Econergy water heater is a very efficient heat pump that heats your water cylinder instead of heating your home. Like a normal heat pump, it moves energy to heat water, not creating the heat by using an electric element. The heated water is passed through the Econergy® into the top of the hot water cylinder where it can be drawn off straight away for use in the house.

That sounds very cool, why should I install one?

Electricity has risen at seven percent above the rate of inflation in the last decade. With partial privatisation on the cards, similar power increases look set to continue.
Hot water makes up about 40 percent of a family’s power bill and installing an Econergy, in many cases, saves around 28 percent on the power bill.

Will I need a new hot water cylinder – or can I use my existing?

The Econergy will connect to any standard electric hot water cylinder. If your cylinder needs replacing, or you’re building, then we can provide an Econergy stainless steel heat pump ready hot water cylinder, which is designed to give you the best possible performance from your Econergy heat pump water heater.

What savings can I expect?

Heating the “Econergy” way is proven to save at least two thirds compared with your electric hot water cylinder - the cheapest primary heating source available. The Econergy® HP4000LT has also been rated by Consumer as the number one heat pump water heater in their test.

So what’s the catch?

There is no catch. The small amount of noise emitted from the heat pump won’t be an issue if the unit is located correctly. All systems are installed with a comprehensive three year onsite parts and labour warranty.
