What is an Air Sourced Hot Water Cylinder with a Built-In Heat Pump?
An Air Sourced Hot Water Cylinder is an unvented cylinder that uses a built-in air source heat pump as its primary heat source, rather than relying on an immersion heater (Direct Unvented) or a boiler coil (Indirect Unvented).
How does a Built-In Heat Pump Air Sourced Hot Water Cylinder work?
- Air Intake and Heat Exchange: The system draws in air from outside your home, passing it through a heat exchanger that transfers the air's warmth to a refrigerant fluid.
- Heat Transfer and Water Heating: The warmed refrigerant fluid is then compressed to increase its temperature, before flowing through a second heat exchanger inside the cylinder to heat the water stored in the tank.
- Efficient Hot Water Supply: The heated water is now ready for use in your home, providing a reliable supply of hot water with reduced electricity consumption, thanks to the use of renewable energy from the air.

FAQ: Hot Water Cylinders with Built-In Heat Pump
Yes, they use around 80% renewable air energy and just 20% electricity, making them more efficient than traditional cylinders.
No, the built-in heat pump is the main heat source, so you don’t need a boiler or immersion heater as standard.
We offer hot water cylinders with built-in heat pumps from 80L up to 250L, suitable for both small homes and larger properties.
An air source hot water cylinder uses a built-in heat pump to draw in warmth from the air and transfer it into the water stored inside the cylinder. The system works by pulling in air, passing it through a heat exchanger, and compressing a refrigerant to increase its temperature. That heat is then transferred into the water tank, providing a steady supply of hot water using mostly renewable energy from the air.
Yes, most homes can install an air source hot water cylinder. They are particularly useful in properties without access to gas, or where homeowners want to reduce reliance on boilers and immersion heaters. They work well in apartments, houses, and even small commercial spaces. The key considerations are available space for the unit and access to airflow for the heat pump intake and exhaust.
The right size depends on the number of people in your household and your hot water usage. As a guide:
80–150 litres: Suitable for 1–2 people or smaller homes.
150–200 litres: Best for medium households with 3–4 people.
200–250 litres: Ideal for larger households or properties with higher hot water demand.
Choosing the correct size ensures you always have enough hot water without wasting energy heating excess capacity.
Savings vary depending on your current system, household size, and energy tariffs, but most users save 30–50% on hot water heating costs compared to traditional immersion heaters or direct electric systems. Because the cylinder uses around 20% electricity and 80% renewable air energy, you’ll see lower bills as well as a reduced carbon footprint. Over the lifetime of the system, the savings can run into thousands of pounds.
