Split System Heat Pumps

Split-system heat pumps are better at heating individual rooms because they provide targeted heating, allowing for precise temperature control in each room. They operate more efficiently by transferring heat directly to the specific areas where it is needed rather than heating an entire house through a central system. The internal heat pump unit can be set to maintain the temperature of the room it serves.

It is easier to maintain existing interior design when utilising split systems due to its flexibility. For example, air-managed systems can be fixed onto a wall, a drop ceiling, or suspended from the roof. In certain circumstances, floor models can also be installed for underfloor heating.

Ductwork expansion projects are challenging to undertake. On the other hand, installing a split heating system in an individual's house is a stress-free and easy job. Connecting indoor and outdoor components can be achieved with a three-inch hole, which is less intrusive than other systems, as conduits are easily accessible in different sizes.

Mini-split systems allow for individual room temperature control, enabling users to heat or cool only the rooms they are using. This eliminates the need to adjust the temperature for the entire house, leading to substantial energy savings.

Split systems possess a great feature of customisation. Other prominent features include increased control and built-in sleep functions.

There are three main categories of heat pumps in New Zealand, and they are all connected via ducts. They are geothermal, air-to-air, and water sources. Heat pumps collect heat from the air, ground, and water outside one's property and use it indoors.

An air-source heat pump is a commonly used heat pump that transmits heat between the outside and inside of a home. Essentially, it operates on the principle of heat exchange, using a refrigerant to absorb heat from the outside air, even in cold temperatures, and then releasing it indoors to provide heating.

Air-source heat pumps are also available in a ductless version for homes without ducts. They are called mini-split heat pumps, an exclusive type of air-source heat pump that produces hot and cold water rather than air. These reverse-cycle chillers are widely used with radiant floor heating, where heat is supplied directly.

Geothermal (ground or water-source) heat pumps achieve higher efficiency by transmitting heat between your home and a nearby water source or the ground. They benefit from stable temperatures and result in low operating costs despite higher installation expenses. They offer several advantages: reducing energy usage, providing consistent and controllable humidity, and fitting easily into various homes, depending on the property, landscape, and subsoil. Prevalent in places like Rotorua, geothermal heat pumps are particularly suitable for severe climates, making them more effective than air-source heat pumps in such conditions.

There's more than one solution for heating and cooling systems in New Zealand. Although a split air system works great, you can also use a ducted heat pump system. However, if you like the idea of having a heated floor, underfloor heating is another option to use to keep your home warm during the winter months.
