If you are thinking of buying a heat pump, one of the latest and the most efficient technology that is available in market today is the Inverter Technology for heat pump.


1. On/Off heat pump is defined as “all or nothing (AON type)”, to ensure it can function properly, its power must meet the condition for thermal balance:
W1 >= Q1 (water heating) + Q2 (lose from water to air)

When the pool is at the right temperature, Q1 is no longer necessary, so the power needed is
W2 = Q2 (lose from water to air)
Q1 is no longer needed, but AON type can’t change its power, so it keeps function as W1 and Q1 is a waste. As consequence, a waste of energy will cost more on electricity bill and the temperature is not stable, in fact the temperature will varied in an interval.

2. Inverter can adjust the speed rate to use a minimum power required to maintain the temperature. It can change from W1 to W2 intelligently to avoid the unnecessary energy used. That is why the inverter is an energy saving technology, to avoid the energy waste. And also the temperature is more stable.

3. AON type has a power rate constant. It didn’t consider the change of environment. Therefore, AON usually is not a full season heat pump, the performance will be very different. It could be too hot in summer or not enough in autumn. Inveter can avoid this problem by changer the power rate.


1. Aquark has a R&D team with 20 years experience of heat pump. We self developed a stepless inverter technology, which is more advance than normal inverter. For example, step Inverter can adjust the speed 20% by 20%, or 25% by 25%. Aquark’s stepless inverter can adjust Hz by Hz to the best condition for using.

2. Aquark has a very strict quality control. Start form raw material and components testing, to the production chain, all the step is strictly follow the process. Our failure rate is lower than 0.5% which is an outstanding number among the manufacture.

3. Aquark’s product has many differences. Those differences make us being unique in the market and bring more attention. Innovation is in every product of Aquark. It’s also one of the key of Aquark to being competitive.


Mr. Silence is redefining the heat pump. It is totally a revolution of heat pump’s technology:

1. Mr. Silence is the first back-discharge heat pump ever. This design is patented, it also represent the strong R&D ability of Aquark.

2. This design can help to decrease the noise. In fact, Mr. Silence is the most silent heat pump in the market. A low noise while functioning will bring a comfortable enjoyment to the user. Mr. Silence’s noise level is 12 dB lower than On/Off heat pump, only 43 dB at 1m distance.

3. Outstanding performance: COP up to 16 certificated by TUV, thanks for the stepless inverter technology. More than 90% of energy used is free from air. This makes it environment friendly.

4. Garden friendly: this remarkable design will hide the fan, eliminate the disturbing wind, and require less space for installation.
