Brand History

Heading

The brand’s history is rated based on its longevity and experience in the market

 The heat pump operates at a noise level of less than 40 dB, making it extremely quiet and ideal for installation near living spaces without causing any disturbance.

‍
 The noise level is between 40 to 45 dB, which is still very quiet and suitable for residential areas with minimal noise concerns.

‍
 The noise level ranges between 45 to 50 dB, making it moderately quiet but potentially noticeable in quieter environments.

‍
 The noise level ranges between 50 to 55 dB, making it more noticeable, but still within a tolerable range for most households.

‍
 The noise level exceeds 55 dB, making it louder and potentially disruptive, especially in more sensitive or quiet areas.

‍

Refrigerant

 The product uses a natural refrigerant like CO2, which has zero ODP (Ozone Depletion Potential) and an extremely low GWP (Global Warming Potential) of 1, making it the most environmentally friendly choice.

‍
 The product uses R290 (propane), a low-GWP refrigerant of 3 that is highly efficient and environmentally friendly, though it requires careful handling due to flammability.

‍
 The product uses R134a, a refrigerant with moderate GWP of 1430, offering reasonable environmental performance, but less efficient than more advanced options. It is not allowed under certain State rebates like in Victoria

‍
 The refrigerant has a high GWP (above 1500) but is still legally accepted in many regions.

‍
 The product uses outdated or harmful refrigerants, which have a high GWP and are likely to be banned due to their negative impact on the environment.
