Air to Water Heat Pumps

Featuring the best air-to-water heat pumps in New Zealand

Air-to-water heat pumps are a preferred home heating option in New Zealand due to their cost-efficiency, ease of installation, and ability to provide consistent heat to large spaces. The right air-to-water heat pump for a space depends on factors such as the size of the area, environmental conditions, building style, insulation, glazing, and ceiling height. Other considerations include whether the space is open-plan, the type of ventilation, and the optimal placement of the heat pump within the room. These types of heat pumps provide instant hot water and heating and are an important part of a wider range of hot water heating systems from trusted suppliers in New Zealand.

Benefits of having air-to-water heat pumps

Air-to-water heat pumps offer several benefits, including high energy efficiency and cost savings, as they utilise ambient air to generate heat, reducing reliance on traditional heating fuels. They provide heating and cooling capabilities, making them versatile for year-round use. These systems are environmentally friendly, producing lower carbon emissions than conventional heating systems. Additionally, they integrate well with underfloor heating and radiators, offering consistent and comfortable indoor temperatures. Easy to install and maintain, air-to-water heat pumps can also increase property value given their growing reputation.  

Types of air-to-water heat pumps

Monobloc heat pumps

These single-unit systems contain all components, including the compressor, heat exchanger, and refrigerant circuit, in one outdoor unit. They are simple to install and connect directly to the heating system.

Split heat pumps

These systems have an outdoor unit that contains the compressor and an indoor unit with a heat exchanger. The two units are connected by refrigerant lines, allowing for flexible placement and reduced indoor noise.

Hybrid heat pumps

These combine an air-to-water heat pump with a traditional boiler. They switch between the heat pump and the boiler depending on which is more efficient at a given time, providing both reliability and efficiency.

High-temperature heat pumps

Designed to deliver higher output temperatures, these systems are suitable for homes with existing radiator setups that require elevated water temperatures to function efficiently. This makes them an excellent choice for maintaining comfort and ensuring effective operations.

How to choose an air-to-water heat pump

When choosing an air-to-water heat pump, consider your home's heating and cooling needs based on size, insulation, and climate. Depending on your existing infrastructure, select between monobloc, split, hybrid, high-temperature, and low-temperature systems. Opt for high-efficiency energy models with a good coefficient of performance (COP) and seasonal energy efficiency ratio (SEER) ratings. Ensure the heat pump suits your climate and check for quiet operation. Look for smart features like programmable settings and Wi-Fi controls. Choose reputable brands with good warranties and consider the initial cost, potential energy savings, and available incentives. Finally, select models with environmentally friendly refrigerants and low carbon footprints for future compliance and sustainability.

Ongoing maintenance

Proper care and maintenance of air-to-water heat pumps are essential for efficiency and longevity. Regularly clean or replace air filters to ensure optimal airflow and check refrigerant levels to maintain effective heating and cooling. Inspect and clean the evaporator and condenser coils, and clear any obstructions around the outdoor unit to ensure proper airflow. Inspect the ductwork for leaks, ensure the thermostat and controls function correctly, and check electrical connections for wear or damage. Monitor the system for unusual noises or reduced efficiency, and schedule professional maintenance checks once or twice a year. In colder climates, prepare the system for winter by checking anti-freeze levels and protecting the outdoor unit from snow and ice buildup. These steps will help keep your heat pump running efficiently and extend its lifespan.

Other hot water heating products you might need

There are several different types of water heaters on the market to consider for your home. For an environmentally friendly choice, a solar hot water system is ideal. However, if long-term savings are your priority, a gas water heater is great, thanks to its durability and minimal repairs. Another popular option is electric water heaters due to their easy installation and ability to provide instant heat.
