Air Source Heat Pumps (ASHP’s)
Smarter, Greener Heating
✓ Save on Energy Bills – Delivers up to 5x more heat than the electricity used
✓ Eco-Friendly & Future-Proof – Uses renewable energy to reduce carbon emissions
✓ Space-Saving & Versatile – Compact outdoor unit with no need for an indoor boiler
✓ Smart & Scalable – Remote control via MSmartlife App and expandable for larger homes
Clivet Air Source Heat Pumps Efficient, Low-Carbon Heating
Clivet air source heat pumps (ASHPs) offer an energy-efficient, low-carbon alternative to traditional heating systems, harnessing heat from the air to provide warmth and hot water for homes and businesses. Unlike gas or oil boilers, which burn fuel to generate heat, ASHPs extract renewable energy from the outside air, delivering between 3 to 5 times more heat than the electricity they consume—a performance known as the coefficient of performance (COP).
Ideal for well-insulated properties, Clivet heat pumps can integrate with existing radiator or underfloor heating systems to maintain consistent indoor temperatures. Their compact, space-saving design means installation requires only an outdoor unit, with no need for an indoor boiler. Advanced features include high-temperature water distribution (up to 65°C), modular scalability for larger properties (up to 108kW), and smart connectivity for remote management via the MSmartlife App.
By switching to a Clivet air source heat pump, homeowners can reduce energy bills, cut carbon emissions, and take advantage of stable, 100% renewable energy sources—future-proofing their heating system for years to come.
✓ Space saving: installed outdoors, no indoor unit is required
✓ Designed for harsh climates: excellent performance at low temperatures and optional 3 to 9kW auxiliary heaters
✓ High temperature distribution an be used: water unto 65C
✓ Modular: combines up to 6 units in cascade for power up to 108kW
✓ Advanced connectivity: management via the dedicated MSmartlife App or via the Modbus port with EFLOControl3 EVO included as standard thermostats.
✓ Can be integrated with Solar PV systems

Air Source Heat Pumps, Pros & Cons
Advantages Of Air Source Heat Pumps
Lower operating costs: If the heat pump systems are sized and fitted correctly by an approved installer, your system will operate at a low cost and save money on your energy bills.
Low Co2 emissions: Currently, electrical energy is the greenest of all energy types available, with wind turbines growing to be the biggest Heat pumping offers many advantages. A heat pump with an air source saves you energy consumption by using less energy compared to a typical heat source. Air Source Heat pumps are versatile in terms of their cost. The ASHP can use a heating or cooling system for heating or water heating.
Disadvantages Of Air Source Heat Pumps
Installation cost: Depending on the size of the property and what is required the costs of the new system may be out of reach for 90% of the population at present. If retrofitting this system to an old house with old radiators and little insulation, the initial costs will be quite large. A modern house with good insulation and a heating system should be cost-effective with a short payback period.
Space required: the air source heat pump will need some outdoor space and some indoor space for a hot water cylinder.
Perceived Noise: At full load, an air source heat pump operates at about 56dba, which is about the same as a conversation at 3ft or light rain. At 3m away from the air source heat pump, the noise levels drop to 35dba or the same as a whisper. An air-source heat pump fan system works hardest when the air is coldest – i.e. in the winter when we are mostly indoors. During warm weather, heat pumps work less hard as they do not need as much air, and therefore the noise is much lower. Positioning the heat pump system is key.
Repairs and Servicing
Air source heat pumps are well-known technology with a lifetime between 20 to 25 years. Just like with boilers, you need to service your air source heat pump annually to ensure it continues to work at its maximum efficiency.

Air Source Heat Pumps, FAQ’s
Is an Air Source Heat Pump it right for my home?
An air source heat pump can be a great investment – it’s a highly efficient way of heating your home, helping you lower your carbon footprint and save money on your energy bills in the long run. But when you decide to install a heat pump, there are several factors to consider.
How does an air source heat pump work?
The air source heat pump absorbs heat from the outside air into a liquid refrigerant at a low temperature. Using electricity, the pump compresses the liquid to increase its temperature. It then condenses back into a liquid to release its stored heat.
How efficient is an air source heat pump?
Heat pumps use electricity to run, but they are more than 100% efficient. This means they produce more heat energy in kWh than they use in electricity. This makes it an energy efficient way to warm your home. By contrast, gas boilers consume more energy than they put out into your home. Modern condensing gas boilers are labelled between 92-94% efficient. Boilers installed before 2005, when new regulations came in, are significantly less efficient.
Is my property suitable for an ASHP?
Air source heat pumps offer an energy-efficient and environmentally friendly way to heat your home, but the suitability of your property depends on several factors, including insulation levels, the type of heating system in place, and the availability of outdoor space.
