Harness the free heat from the air with an advanced air-source heat pump. This renewable energy water heating technology will reduce home energy costs whilst providing a plentiful supply of hot water day and night in all weather conditions.

Hot water is a basic household need and there are few things more soothing than relaxing in a warm shower or bath. There are however, few things more frustrating than running out of hot water just when you want it. With a heat pump, reliable hot water is always on tap, regardless of the weather.

An energy efficient heat pump is a great way for households to reduce their energy consumption and cost of living. They are ideal for the replacement off old electric water heaters, where residential gas reticulation is not available and when roof- mounted solar collectors are not feasible.

The Enviroheat system is the perfect partner for your rooftop solar system. Whether you have an existing solar system on your home or you are considering it for the future, the Enviroheat is the perfect choice to add to your system to gain maximum benefit from the energy generated by the sun.

Our advanced control system is equipped with an automatic timer that allows you to maximise solar power generated during the daytime at night time. A second timer allows for an early morning boost to ensure you ever run out of hot water.

How Does the Enviroheat 250L Heat Pump Work?

Air-source heat pumps, in general, work by transferring heat from the outdoor air to the desired area, such as a pool or a building.

The heat pump contains a refrigerant that evaporates at a low temperature. The outdoor unit consists of a coil with the refrigerant inside. The coil absorbs heat from the surrounding air, causing the refrigerant to evaporate into a gas.

That refrigerant is then compressed, which increases its temperature and pressure, raising the energy level of the refrigerant.

Hot, pressurised refrigerant gas flows into a condenser coil which releases the heat it carries into the pool water, raising its temperature. As the heat is transferred to the pool water, the refrigerant condenses back into a liquid state.

The high-pressure liquid refrigerant then passes through an expansion valve, which reduces its pressure – causing it to rapidly cool and return to a low-pressure, low-temperature state.

This cycle continues as the refrigerant is circulated back to the outdoor coil to absorb more heat from the outside air – repeating until the desired temperature is reached.

By utilising this heat transfer process, air-source heat pumps can efficiently warm pool water by extracting heat from the outdoor air, even in colder climates. They are considered a more energy-efficient heating option compared to gas heaters since they don’t rely on fuel combustion and instead leverage existing heat in the air.
