Eco-Smart Hot Water

Transform your energy expenses with advanced water heating systems that promise up to 70% savings, blending eco-conscious living with cost-effective luxury.

Hot Water Heat Pumps

Hot water heating accounts for around 30% of the average household energy bill. Choosing the right system for your needs can make a real difference, especially to your monthly expenses.

Whether you are replacing an existing water heating system, building a new home or just researching your options, we are happy to help. A Calitec hot water heat pump split system could be the perfect solution.

These are available in 250 litre and 300 litre stainless steel hot water cylinders, plus other sizes on request. Wetback (hot water from wood stove) and solar coil options are also available.

Energy Efficient

What makes Calitec so unique?

  • Their robust stainless-steel refrigerant cycling split system is designed with Kiwi homes in mind and is easy to install in both new and existing homes.

  • The heating capacity is almost twice as much as a standard electric heater, ensuring a recovery time twice as fast as usual for your hot water cylinder.

  • Split System Design – maximum flexibility, keeping the outdoor unit out of sight.

  • Intelligently controlled set and forget system.

  • Wet back option for more savings. PV solar compatible.

  • Reliable in all weather and in all seasons.

Eco friendly & long lasting

Is it a ‘green’ system? Yes, we think it is the most economic domestic hot water system currently available in New Zealand.

Why? By using the best materials we are convinced that it is a very long lasting system. That is why our hot water cylinders have a 20 years warranty and the outdoor heat pump unit has a 5 year warranty.

Unlike other heat pump hot water systems where you have to change the complete system, only the outdoor heat pump unit has to be replaced after its expected lifetime of 10 to 15 years. This reduces purchase and installation costs and also reduces the amount of waste. Economic efficiency = ((Purchase & Installation Cost) / Lifetime) + Annual Running Costs.

Enjoy savings of up to 70%!

An average shower will cost you around $1*. With our heat pump technology we can heat up your water with 70% less energy - which means that same shower will only cost you 30 cents.

How much will I save?

A hot water heat pump can save you up to 70% of your water heating costs. Every household’s water usage is different so finding good, trustworthy information for your personal situation is important to help you understand all your options.

With electrical, gas, solar or heat pump hot water, there are so many options today. What are the differences and what is the most cost effective and environmentally friendly option for your family?

To find out your total savings it's important to compare the upfront costs (purchase and installation), annual running costs, and lifetime costs of different types of hot water systems. ​ In many situations a hot water heat pump system will be much more efficient than traditional electric or gas water heaters. Heat pump technology can heat up your hot water cylinder with just 30% of the energy, compared to other systems. Heat pump technology works day and night, in all seasons and in all weather conditions.

“We were dealing with another Air Conditioning Company that were not living up to my expectations, Air Mc were recommended by some of my friends in the Building Industry. I would thoroughly recommend Air Mc to any person or company as they are the most reliable and trustworthy team that I have had the pleasure to work with and would recommend them to anyone needing Air Conditioning and Refrigeration installs and servicing in their home or business.”

“Excellent service from the initial communication to the end of the job. It was not an easy job hence I battled to find anyone willing to take it on. Many other companies are full of promises and no delivery. This company is not like them. Price was very reasonable as well.”

Great company to deal with. I had contact with a few other businesses about replacing a heat pump for our lounge but these guys were by far the best for communication, value and timing. My brother used a differrnt company a few weeks prior who left the exposed cables live and had to come back several times! Their communication with pricing and options was very efficient and we were able to arrange a quick turn around for install. The guys turned up on time and made light work of the job + removal of old unit Would definitely recommend to others
