Grant air source heat pump

With one of the broadest ranges on the market and a focus on providing sustainable heating solutions, Daikin is one of the best established air source heat pump manufacturers in the UK. Whether you want a monobloc, split, high temperature or low temperature heat pump, Daikin will have a solution that suits your needs.

Outdoor units

Whether you're looking for a high temperature or low temperature air source heat pump for your home, you will always require an outdoor 'fan' unit. This will extract air from outside your property and use it to produce heat for your home.

Low temperature heat pumps

Low temperature air source heat pumps from Daikin are available in 2 different unit types; monobloc or split. There are details for each of these unit types below.


Altherma 3 Monobloc

This range of all-in-one outdoor units includes models with high output capacities, has a single set of compact unit dimensions across all output sizes, and has an attractive sleek design which makes it suitable for installing outside of different property types without being obtrusive.

Key features:

  • Compact dimensions for all output sizes (H x W x D – 870mm x 1,378mm x 460mm)
  • Horizontal front grille for more attractive design and reduced noise
  • Uses R32 refrigerant
  • Compatible with a range of control panels and the Daikin Residential Controller App
  • Separate hot water storage tank required for hot running water

Altherma 3 Split

These outdoor 'fan' units are used in conjunction with the Altherma 3 indoor units to provide heat throughout your home. As the work required to heat your home is shared between an indoor and outdoor unit, these outdoor units are smaller than the monobloc model.

Key features:

  • Smaller size and weight allows for roof and terrace mounting
  • Weather resistant due to an anti-corrosion treated heat exchanger
  • Uses R32 refrigerant
  • Must be paired with a Daikin indoor unit to function

High temperature heat pumps

In order to fulfil the heat requirements of homes with traditional radiators, Daikin has created a split heat pump solution capable of heating water to a temperature of 70°C.

A winner of the Red Dot Design Award in 2019, this outdoor unit has an attractive front horizontal grille which conceals the fan itself, and provides a sleek unassuming design. The amount of noise produced by the unit is reduced by the front grille. It also has a low sound mode for even quieter running.

Key features:

  • Compact dimensions for all output sizes (W x H x D – 1,270mm x 990mm x 460mm)
  • Uses R32 refrigerant
  • Can be used with existing traditional radiators
  • Must be paired with a Daikin indoor unit to function
