Heat-Pumps

What is a Heat Pump?

A heat pump is an ingenious device capable of providing both heating and cooling to your home and providing domestic hot water efficiently. It makes use of reversing valve technology to change the direction of the refrigerant flow, enabling it to extract heat from the outside air to warm your house during winter, and reversely discharge heat outdoors to cool your home in the summer. It is a green replacement to your old boiler.

How Does It Work?

Why do we say it “moves heat” instead of “generates heat directly”? Using a refrigerant cycle, it absorbs heat from a low-temperature source (like outdoor air, ground or water), then compresses and heats this refrigerant to release the stored heat into a higher-temperature space (such as your home).

This process is similar to a refrigerator operating in reverse: while a fridge moves heat from its inside to the outside, a heat pump moves heat from the outside into your home.

Take an air-source heat pump as an example—here’s how it works:

• Evaporation: The evaporator is the place where refrigerant and outdoor air exchange heat, turning the refrigerant from liquid to gas as it absorbs the heat from the air.
• Compression: After evaporation, the refrigerant enters the compressor, which compresses it into a hot, high-pressure gas for the condenser.
• Condensation: The condenser is the place where refrigerant and water exchange heat, turning the refrigerant from gas into liquid as it releases the heat to water.
• Expansion: After condensation, the liquid refrigerant flows through an expansion valve, reducing pressure and turning it back into vapour, and then goes into the evaporator for the next cycle.

Core Advantages of Heat Pumps vs. Traditional Heating Systems

High Efficiency & Cost Savings

Heat pumps use far less electricity than traditional boilers to deliver the same amount of heat. This means lower energy bills and reduced energy waste.

Lower Carbon Footprint

By minimizing electricity use and avoiding fossil fuels (like gas or oil), heat pumps slash CO₂ emissions, supporting a greener, more sustainable future.

One-stop Comfort

Heat pumps provide year-round solutions: heating in winter, cooling in summer, and even hot water production. Their flexible design allows seamless integration with solar panels (PV systems) and battery storage for smarter energy use.

Energy Independence

No more worries about fossil fuel shortages or price spikes driven by geopolitical issues. Heat pumps break your reliance on oil and gas, insulating you from market volatility.

Flexible Installation Options

Monobloc systems

• All components are integrated into a single outdoor unit, connected to indoor water system terminals via pipes.

• Compared to split systems, this compact setup requires less financial investment, installation effort, and indoor space, enabling quick and easy deployment.

Split systems

• Components are divided into an outdoor unit and an indoor unit, connected by refrigerant pipes, offering excellent anti-freezing performance.

• The indoor unit features a slim design, saving indoor installation space and easily blending into home environments.
