Heat pumps

Heat pumps are the perfect partner for heating and cooling systems designed to work at lower water temperatures, helping to support the design and construction of more energy-efficient buildings.

Types of heat pumps

Air Source Heat Pumps (ASHPs)

are an ideal solution for residential and commercial projects of all sizes including high rise buildings. Easy to install and requiring limited space, they offer a flexible solution for both new builds and refurbishments.

Ground Source Heat Pumps (GSHPs)

have a larger space requirement than their air source or water source counterparts but offer a better all year-round efficiency. They are ideal for projects where early consideration can be given to ground works and infrastructure.

Water Source Heat Pumps (WSHPs)

are best suited to developments that are located near a large body of water. This could include a canal, borehole, lake or river, where they can draw heat energy from.

Hot Water Heat Pumps (HWHPs)

are a low carbon technology for heating hot water, designed to be installed within a building. This allows specifiers their choice of space heating technology, such as gas boilers or direct acting panel heaters, as part of a hybrid system.

Heat pump support

Application design

When using a GDHV heat pump, our engineers are able to offer advice on designing a heat pump into your scheme, including buffer vessels and cylinders and hydraulic schematic advice for both single and cascaded units.

Quality and range

GDHV manufacture a wide range of high-quality heat pumps, including reversible and high temperature ranges. We have solutions suitable for internal and external installation, as well as heat pumps that are MCS approved.

Efficiency and cost

Developing heat pumps that have high efficiency in relation to their cost is key at GDHV. The true efficiency of our products can be seen through the Coefficient of Performance (COP) calculations.


GDHV offer a wide range of CIBSE accredited CPDs covering different aspects of the design and specification of heat pumps. All CPDs can be delivered online or in person.
