Stiebel Eltron Heat Pump Faqs

What is a heat pump?

A heat pump represents an energy-efficient and eco-friendly apparatus that maximises the utilisation of low-quality thermal energy. While heat naturally moves from hot to cold, it doesn’t naturally reverse direction. The operation of a heat pump involves a mechanical process that compels heat to move from a lower-temperature source to a higher-temperature destination in a reversed cycle. This mechanism consumes only a minimal amount of energy to achieve a significant heat transfer, effectively harnessing and conserving low-quality heat energy that would otherwise go to waste, thereby promoting energy efficiency.

Why is a heat pump low-carbon and eco-friendly?

The heat pump operates without releasing harmful gases, greenhouse emissions, or acid rain pollutants, and it doesn’t generate waste heat pollution. Opting for a heat pump equates to embracing a lifestyle that is both environmentally friendly and low in carbon footprint.

What are the features of a Solar Heat Pump?

The Solar Heat Pump incorporates panels into its system to facilitate heat exchange with the external environment using refrigerant, eliminating the need for components like motor fans and four-way valves. This results in a straightforward design, compact dimensions, cost-effectiveness, and minimal noise levels. The system draws from various heat sources, including solar energy, ambient air energy, wind energy, and rainwater energy, ensuring a continuous supply of hot water around the clock, free from environmental limitations. It maximises the capture of natural energy and can harvest heat from a broader area, achieving an impressive maximum COP of 6.0.

What are the features of an Air Source Heat Pump?

The Air Source Heat Pump harnesses the ambient air as both a heat and cold source for heating and cooling purposes. Thanks to its superior cooling and heating capacity, which surpasses the energy consumption of the heat pump, it stands out as an efficient and energy-efficient product. This system combines heating, cooling, and domestic hot water functions seamlessly. Leveraging DC frequency conversion technology, it achieves an A+++ energy efficiency rating. With the adoption of EVI technology, it can operate efficiently even in extremely cold conditions as low as -30°C. Additionally, it incorporates innovative noise reduction technology, resulting in exceptionally low noise levels. It utilises the environmentally friendly R32 refrigerant, ensuring minimal environmental impact.

What are the features of CO₂ Heat Pump?

The CO₂ Heat Pump employs an environmentally friendly natural refrigerant. It operates by compressing the CO₂ refrigerant into a high-temperature, high-pressure supercritical fluid. This fluid then enters a gas cooler to exchange heat with water. The water absorbs the heat, causing its temperature to increase. Subsequently, the high-pressure fluid passes through an expansion valve, where it undergoes depressurization, absorbing heat from the surrounding air in the evaporator, and transforming into a low-pressure gas. The gas is then drawn back into the compressor for compression, initiating a continuous cycle that results in the production of hot water.

The CO₂ Heat Pump excels in high-temperature heating performance, capable of delivering water at temperatures exceeding 90℃. It also performs admirably at low temperatures, with the ability to produce high-temperature hot water even in extreme conditions as low as -35℃ ambient temperature. Moreover, it boasts high energy efficiency and a broad range of applications, operating effectively within an ambient temperature range of -35°C to 43°C. This versatility makes it suitable for generating domestic or industrial hot water in most geographical areas.
