Air to water electric heat pumps explained: an eco-friendly option in commercial heating and cooling

22 September 2022

The rise of heat pumps in Australia

Air to water heat pump systems are emerging as a sustainable alternative to traditional commercial heating and cooling system options in the Australian market. Heat pumps offer an environmentally friendly solution, primarily because they can use renewable electricity as their energy source.

Heat pump efficiency and application

Heat pumps are specifically well-suited for low-temperature systems like underfloor floor heating & cooling. This is due to their lower operating temperatures compared to traditional heating solutions i.e. gas boilers. While it is now possible to obtain Hydronic heat pumps with higher operating temperatures this can negate the environmental benefits due to the increased cost and energy consumption.

How air to water heat pumps work

An air to water heat pump operates by transferring heat from the ambient air into a water based system, essentially recycling heat from the environment. This is notably more energy-efficient than traditional systems that burn fossil fuels to produce heat. By leveraging the existing warmth in the environment rather than generating heat from scratch, air to water heat pumps can provide significant energy savings, which is what makes them a sustainable choice for commercial climate control and water heating needs.

Climate considerations for heat pump installation

Typically, heat pumps are ideal for climates that require moderate heating or cooling. In water heating applications, a hydronic heat pump works similarly to a refrigerator. Electricity powers the heat pump, pumping refrigerant through the system. This refrigerant absorbs heat from the air and transfers it to the water in the tank, effectively warming the space while expelling cold air back into the atmosphere.

BAXI Auriga A Heat Pump

Ideal for commercial and residential applications, available in a multitude of outputs, this model can be teamed with renewable solar power for maximum benefit. This is a highly efficient monobloc solution for all commercial project needs. Download data, specification, and installation details for the BAXI Auriga A Heat Pump.

Can heat pumps be used in winter and summer?

During winter, heat pumps draw heat from the cold ambient temperatures outdoors to warm the indoor space, whether that be a residential home, multi-level build, or large-scale commercial space. Conversely, in the summer, they can reverse the cycle, transferring heat from your indoors back outside, offering commercial heating and cooling solutions for all seasons.

BAXI Auriga A Heat Pump

With near silent operation, this compact heat pump offers heating of space and hot water up to 65 degrees Celsius. With up to six capacities available it also offers electronic management of eight different climatic curves for maximised performance and boasts A+++ energy efficiency.

Types of heat pump systems: ‘Split’ vs. ‘Monobloc’

The terms ‘split’ and ‘monobloc’ indicate the configuration of a heat pump system. Monobloc versions incorporate all components into one external unit placed beside the building, making them easier for heat pump installation. Split systems, however, have both an external unit with a heat exchanger and an internal cassette unit situated inside the property. At Hydro Heat, we are proud to supply the BAXI Auriga A range of air-to-water Monoblock heat pumps. These quality products offer an environmentally friendly and sustainable solution for commercial heating and cooling. If you’re looking to install floor heating that can integrate easily with solar panels, these products are the answer with options available up to 16kW simple single unit installation.

Heat Pump sustainability: powered by renewable electricity

One significant advantage of heat pumps is that they run on electricity. When this electricity is sourced from renewable options like solar or wind, it makes hydronic heating solutions both efficient and sustainable. Pairing a heat pump with solar panel installation on your commercial projects will not only benefit the environment but also be a solid marketing angle, particularly for multi-level residential projects.
