Hydronic Air to Water Heat Pumps
If you’re looking for an energy efficient means of providing your home with hydronic infloor or radiator heating and Geoexchange is not the option for you then the next best option is an air to water hydronic heat pump. Hydronic air to water heat pumps harvest the natural stored renewable energy in the air to efficiently create heated and chilled water. We have selected units from two of the worlds leading manufactures that we feel are the best quality with the highest efficiencies on the market.
The Uses of a Hydronic Air to Water Heat Pump
The main use for a hydronic heat pump is providing heated water to your hydronic floor heating system, but they can also be used to provide heated water to hydronic radiators, hot water for domestic purposes (washing etc) and pool heating.
The Difference with Our Heat Pumps
Not all hydronic heat pumps are created equal. Due to the Stiebel Eltron heat and NIBE pumps being manufactured in Europe they have to meet an extremely high testing regime that is not replicated anywhere in the world. Another huge difference between most other hydronic heat pumps on the Australian market and the Stiebel Eltron and NIBE units is the control system supplied with the heat pump is integral to its greater efficiency. Where most heat pumps except an “dumb” on/off signal from your control system the Stiebel Eltron and NIBE heat pump monitors internal home temperature, external air temperature and the temperature of the water in your heating system and adjusts it accordingly giving you a greater level of comfort and a higher level of efficiency.
Air to Water Heat Pump System Overview
The above diagram shows and overview of a hydronic infloor heating system utilising a Stiebel Eltron air to water heat pump. You will see a heat pump, HMS trend heat pump controller/pump set, buffer tank and a hydraulic module. Using the above kit gives you a total system solution.
Why use a buffer tank?
If you have been looking at hydronic heating systems for your home utilising other heat pumps you may notice we have included a buffer tank. You may ask why have we included this when others haven’t or say you don’t need one? This is because the primary role of a buffer tank is used to keep a minimum volume of water in the heat pump circuit at all times even when the heating load is very low. This prevents the heat pump from short cycling and provides a bypass route to maintain the minimum flow rate through the heat pump if most of the heating zones have shut down or have a reduced flow. Both the minimum flow rate and the minimum volume of water in circuit are necessary to keep the heat pump happy and operating to the manufactures tested specifications. Even on an inverter heat pump a buffer vessel is recommended.

Peace of Mind
Stiebel Eltron started life in the 1930’s manufacturing instantaneous water heaters adding the development and manufacturing of heat pumps in 1976. This gives us confidence that not only has the company been around for a while they have over 40 years of heat pump experience. This is a rarity in hydronic heat pump manufactures bringing equipment into Australia with most being made in China often pieced together with inferior components.
