Air Source Heat Pumps

Energy-saving Heating & Cooling Packages From Worcestershire Garden Buildings


Climate Control

For garden offices & home studios

If you thought air conditioners were just for cooling then think again, because modern "air-to-air" heat pump systems now incorporate reverse-cycle technology so they can deliver low cost heating as well.


Compared to conventional electric heaters, air-source heat pumps (ASHP's) are the most energy-efficient heating systems available, providing homeowners and businesses with an affordable "all-in-one" solution that can deliver heating, cooling, humidity control and air filtration.


At WGB we recognise the benefits of ASHP systems, so to compliment our 2021 range of garden offices and home studios we now offer an exciting range of air conditioning packages that let you work, learn, train or play in a healthier and more energy-efficient climate controlled environment.


Conventional Heating

Comparing running costs

Gas central heating is widely recognised to be the cheapest form of domestic heating, regardless of the initial installation and ongoing maintenance costs, where the average unit price for gas in the UK is just 3.8p per kW/h.


In comparison, electric panel heaters, convectors and oil-filled radiators are a popular choice because they are relatively inexpensive to buy, cheaper to install and require no ongoing maintenance. The only downside is they rely on peak-time electricity that has an average cost of 14.37p per kW/h.


Night storage heaters are still considered to be the cheapest form of electric heating because they use Economy 7 Off-peak electricity, which costs around 50% less than the regular Peak-time tariff. However, whilst in principle they should be cheaper to run, they actually require double the input to achieve the output required.


For example, a night storage heater with an output rating of 1.5kw actually has an input requirement of 3.3kw to pre-charge the energy cells inside with enough stored heat to meet the output requirements that day.

Air Conditioning

Comfort, control and reduced energy bills

At best, a 100% efficient electric radiator can produce 1kw of heat energy using 1kw of electricity, whereas an air conditioner using heat pump technology can produce over 4kw of heat energy using the same amount of electricity.


Lets imagine your new garden studio uses 2kw of heat energy per hour to keep you toasty for 6 hours a day during an average 20 working day month. The cost of using an electric panel heater would equate to £1.72 per day, costing £34.40 per month during an average heating season.


In comparison, an air conditioner using heat pump technology to deliver the same amount of heat over the same period would cost less than 10p an hour, so in the worst case scenario it might cost £12.00 a month, saving at least £22.40 per month in running costs.


Of course, another clear advantage over gas and conventional electric heating systems is that ASHP system are an all-in-one solution that can deliver both heating and cooling, with additional features such as humidity control and air filtration to make your studio comfortable to use all year round.

Choosing your System

Select Output Rating

System Size

Our air conditioning heat pump systems are categorised into 4 groups based on their nominal output ratings:-


  • 2.5kW

  • 3.5kW

  • 5.0kW

  • 7.0kW


If you are unsure of the size you need you can use use our handy online calculator to find the minimum number of watts required before selecting a system from any group that has a greater nominal output capacity.


Remember, the output in kilowatts refers to the amount of heat energy a system can produce and not the amount of electricity used to produce it. As a general rule of thumb most air conditioning heat pumps systems only consume 200-300w of electricity for every 1000watts (1kW) of heat energy they produce.
