Air Source Heat Pumps (ASHPs)
High efficiency air-to-water units providing renewable heating and cooling services to domestic and commercial buildings.
Get in touchAir Source Heat Pumps
Air source heat pumps (ASHPs) are an ideal solution for most project types and sizes, as they don’t require as much space and are generally easier to install than a ground or water source heat pump.
Benefits
Ease of installation
ASHPs offer quick and easy installation as they only require an electrical and water supply connection. Their key consideration is to allow for air flow, making them an ideal solution for projects where space for a ground or water collector is limited.
Efficiency and range
Heat pump efficiency is measured as a Coefficient of Performance (COP). Our highly efficient ASHPs have a COP of circa 3.5+ at a water temperature of 35°C, including internal and external units, with reversible options for comfort cooling. We also offer evaporator protective coatings to extend system life-span against corrosion.
Testing and standards
GDHV have multiple heat pump factories, including in Germany, France and Ireland, with access to state-of-the-art testing facilities to provide you accurate heat pump information. Our products are tested to the latest EN standards, including EN15316, EN14511 and EN14825.
Application design
When choosing our ASHPs our application engineers will be able to offer advice on applying the solution to your project. This includes hydraulic schematic advice for single and cascaded units, alongside guidance on buffer vessels and water cylinders.
Product specification
We offer a range of three phase air source heat pumps for commercial and residential applications:
Product Range | Description | Nominal Rating at A10/W35* | Controller | Max Flow Temp |
---|---|---|---|---|
LATU | High efficiency air to water heat pump for external applications | 25 -60kW | WPM ECONPLUS controller This is a BMS compatible controller via additional plug in cards, able to work with BACnet and ModBus | 58-65°C |
LITES | Air to water heat pump for internal applications | 9 – 28kW | 60°C | |
