Hot water heat pump

Hot water heat pumps use the same technology as your standard room heat pump, meaning fantastic energy efficiency when compared with an electric hot water cylinder.

Mature Technology with Recent Advances

Heat pump hot water (HPHW) technology has been around for at least the last 40 years. With the latest refinements, they have secured their place among the most efficient home heating sources available. Hot water heat pumps essentially extract and concentrate heat from the air outside your home and force it into a water tank, giving you a source of hot water. This process uses less energy than it transfers, meaning you get out more heat than you put in electricity.

Air-source HPHW is a great option in Tauranga and the Bay of Plenty region because the ambient air temperature does not often go below 11 degrees.

We Offer Proven & Trusted HPHW Systems

Eco Plumber & Gasfitter prefers the HPHW systems that we have seen to be reliable, with the best efficiency and great after-sales service. Rinnai is one of our trusted brands, as is Econergy.

The Econergy hot water heat pump has been tested and proven to be among the most efficient units on the market, with up to 70% energy savings, where some brands only deliver 50% energy savings (when compared with electric). When the system is on standby, no power is used. The Econergy heat pump is able to be fitted to new installations and retrofitted to existing hot water systems. Econergy is a quality New Zealand-made product.

Further advantages for an Econergy hot water heat pump system are low installation costs and no building consent required. The location of the unit is flexible and just like standard hot water cylinders, they can be connected to ‘ripple control’ power, meaning they take advantage of the lower electricity rate offered by your power company. They are especially suitable for families who have high levels of hot water usage.

Eco Plumber & Gasfitter has many happy clients in Tauranga and the Bay of Plenty after fitting Econergy hot water heat pumps. Contact us today to find out more.

We wish to acknowledge the awesome service provided right before Christmas Eve. Very grateful for your willingness to accept the job and get it done – which meant our son and family could enjoy a well-deserved holiday with running water!!! Please pass on our appreciation to the staff as well. We will be recommending your business.

We have had Dale to our place three times - underfloor heating problems, gas hot water issues and a stove service. Each time he arrived at said time and explained everything as he fixed the issues. Great communication and would highly recommend. Thanks.

I booked Eco Plumber to relace a shower rose. Due to a change with one of their appointments. They came the same day I booked them. Brilliant service. Prompt. Took all the discarded bits with them. Very fair charge. I will use their service again.
