Connection of a buffer tank ensures minimum compressor run times and minimum water flow rates through the heat pump to maintain optimum efficiency. A buffer is essential for air source heat pumps as it provides the energy source for defrosting. Where the heat pump provides the sole source of heating, an electric immersion element can also be integrated to provide supplementary heating if required.

Modules matching the specific requirements of the heat pumps simplify connection to the heating system and offer the option of flexible expansion for domestic hot water or additional heating circuits.

The most common components are:

A) Compact manifold allows connection between heat pump, buffer tank and a single heating circuit, simplifying the installation process and reducing space.

B) hot water module allows connection between the heat pump and the hot water cylinder or second heating circuit.

C) Manifold bar allows simultaneous connection of the compact manifold and hot water module.

For the central hot water supply NOBO heating UK offers a range of unvented hot water cylinders, sized correctly for the maximum heating capacity of the heat pump. it is important to remember that due to lower flow temperatures, correctly sized heat exchangers are required to maximise performance. An integrated temperature sensor is connected to the heat pump manager, allowing the heat pump to automatically manage the production of hot water as well when required.

All heat pump cyclinders are fully UK approved for G3 Building regulations
