Hot Water Heat Pumps/Central Heating

Heat & Cool Your Rooms, Underfloor Heating & Hot Water Heating,

All From One System! 

On average, over half of a home’s energy consumption is taken up by traditional hot water and heating, so when considering how to reduce energy costs and improve heating efficiency, it makes sense to turn to hot water heat pump technology. 



Heat pump technology that revolutionised home heating in New Zealand can be just as effective and efficient at heating your home’s hot water.

How Does a Hot Water Heat Pump Work?

Just as a heat pump that heats a room in your home, the outdoor unit uses electricity to absorb available heat energy from the surrounding air and then transfers it to your home so it can provide energy efficient hot water heating and heating for underfloor or radiators. 


The option of an installed hot water cylinder provides your home with hot water and integrates with the outdoor unit to create a whole home water heating and central heating solution.


Hot water heat pumps work without the need for oil, flammable gas or other hazardous substances, reducing the potential risks that these fuels can create. Therefore,  having no need for a gas connection or a fuel tank.

Whole Home Central Heating & Hot Water Heating Combined

With hot water heat pump technology, whole home central heating can now be combined with hot water heating, all in one system. 

These total home heating solutions provide room heating using radiators as well as underfloor heating. It is the ultimate in total home comfort.

Underfloor Heating

Underfloor heating is evenly distributed; radiant heating that provides the ultimate in comfort that you cannot see. Hidden from view, under floor heating is particularly suited to modern open plan homes with higher stud and exposed ceilings.

Radiator Heating

Radiator heating elements are the ideal solution for responsive heating that can be mixed and matched to each room. Quick to heat up as well as turn down or off, radiator heating is easy to control and manage room by room.

Renovating or New Build

There are hot water heat pump solutions ideal for new homes (as the underfloor piping can be installed during the construction phase) and for existing homes where the piping can be connected to radiators installed around the house.



Hot water heat pumps are perfect for installation in new and existing homes as their design allows them to be connected to most types of water cylinders in good condition.

Daikin Altherma 

Daikin Altherma Hydronic Heating Systems are highly flexible, energy efficient home heating systems. At the heart of the system lies an innovative air to water heat pump that provides hydronic heating and cooling all year round. Unlike traditional hot water heaters, the hot water does not stay in the storage tank, it is heated instantly as it passes through the tank. 

There are several different options available to provide heating in your home and Altherma is compatible with all of them. The selected system can simply be connected to the Altherma unit. The below can be connected to your system:

  • Underfloor heating: possibly the best solution for new installations, maximum comfort and efficiency due to radiated heat and is unobtrusive.
  • Fan coils: able to heat and cool, cased or concealed units, individual control & easy installation
  • Radiators: traditional heating solution, low capital cost & easy installation

Mitsubishi Electric’s Ecodan

Ecodan is an advanced heat pump system that cleverly combines the hot water heating supply for a home with energy efficient whole home central heating; all through the same system.

With proven Mitsubishi Electric Technology, Ecodan is designed for New Zealand conditions; maintaining high performance during the winter months when heating is in high demand. Whether you need central whole home heating, hot water or both, Ecodan Hydrobox and Cylinder Systems can provide the perfect solution.


Packaged Cylinder System

The 200 litre Cylinder provides improved performance and fast heat-up times through the use of Plate Heat Exchanger Technology and FTC5 Control. The Cylinders are completely pre-plumbed and wired for ease of installation. The Cylinder can provide heating and hot water to your home.



Packaged Hydrobox System

The Hydrobox is primarily for space heating in the form of underfloor or radiators or a mixture. With a small footprint and sized similarly to gas hot water systems, they are a highly adaptable solution for retrofit and new builds. For systems where a 3rd Party Cylinder with a heat exchanger coil is to be installed, this can be easily catered for by adding a 3-Way Valve to the system and connecting to the FTC5 Controller.
