Garden buildings are proving to be an increasingly popular and cost-effective way to extend lifestyle and business space in a wide range of facilities.

Beyond a simple garden shed for storing tools and potting plants, modern garden buildings provide high quality, year-round accommodation for a variety of purposes. These include garden offices, garden studios, garden lifestyle spaces and simple relaxation areas.

The one thing that all of these high-quality garden buildings have in common is a need for heating and cooling throughout the year. Choosing the right garden building air conditioning solution is therefore very important.

There are several ways to approach garden building air conditioning:

Separate heating and cooling systems

The old fashioned approach used to require a combination of an electric heater for the winter and, perhaps, a cooling-only air conditioner. In reality, though, most such garden buildings and garden offices did without the cooling system and occupants simply sweltered their way through the summer. Apart from comfort issues, a key disadvantage of this approach is that electric heaters are expensive to run.

Heat pump air conditioning

As heat pump technology has improved over the last couple of decades the heat pump air conditioner has become the garden building air conditioning solution of first choice. This is because the same system provides both heating and cooling – with the heating being almost ‘free’ as heat is extracted from the surrounding air. There are two ways to provide heat pump air conditioning for garden buildings.

Split system air conditioners

Split systems comprise an indoor unit and an outdoor unit, connected by refrigerant pipework to enable a refrigerant to flow between the two. These split systems are very effective offering high seasonal efficiencies and performance. Split air conditioning can either be high wall splits or ceiling cassette systems as per the below images. If space and appearance is not an issue, then the split air conditioner might be your solution but they do have to have a large outdoor condenser which may look unsightly on your brand new garden building.

No outdoor condenser air conditioners

No outdoor condenser air conditioners have a built-in evaporator and condenser so there is no need for an outdoor unit. Indeed, they have a minimum visual impact on the building facade, with just two small external grilles that are only open when the unit is operating. Also, there is no requirement for refrigerant pipework so they are easy and quick to install and are not subject to F-Gas regulations. They can also be connected to a standard 13A supply with a conventional plug for ease of power connection.

In terms of energy performance, modern condenser-less heat pump air conditioners are able to provide Class A efficiency in line with new energy labelling regulations. Use of the latest generation of DC fans makes a further contribution to energy efficiency and the ability to provide low carbon heating at ambient temperatures as low as -10°C is a significant benefit.

Noise levels are also very low, compared to earlier versions of these units. Modern designs can achieve noise levels as low as 27 dB at one metre on low speed.

Powrmatic Vision condenser-less air conditioners

Powrmatic’s Vision heat pump air conditioners deliver all of the advantages of no outdoor condenser air conditioning discussed above, along with a stylish contemporary design and advanced control functionality accessed through a touchscreen display or remote controller. Advanced design and superior performance were key reasons why manufacturers are choosing Vision units for many of the garden offices and other garden buildings they supply.
