Air & Ground Source Heat Pumps


Air Source Heat Pumps
With the ability to tether to current heating circuits – and work particularly well with Solar PV and underfloor heating systems – ASHPs provide a constant low level heat that has proven especially effective in off-gas spaces.
- High Efficiency – Air Source Heat Pumps can delivery two to four times more heat energy that they consume
- Heat Transfer – ASHPs work by transferring heat from the outside air to the inside, making them effective even in cooler temperatures
- Heat & Cool – ASHPs can be used for both heating and cooling, making them a versatile option for year-round comfort
- Perfect for UK Weather – ASHPs efficiency is generally maximised within a typical range of between -20°C and +20°C


Ground Source Heat Pumps
Free yourself from the constraints of oil and gas, with a Ground Source Heat Pump. Capturing heat from the ground, and transferring it to your home or workspace to heat your space and hot water, Ground Source Heat Pumps work all year round, and provide a constant, reliable and renewable source of energy that is up to 300% more efficient than traditional heating systems.
- High Efficiency – Ground source heat pumps are highly efficient due to the stable temperature of the ground, which allows them to heat with minimal energy input
- Consistent Heating & Cooling – GSHPs are typically not affected by weather conditions
- Quiet Operation – The average ground source heat pump makes very little sound
- Flexibility – GSHPs can be adapted to various heating and cooling needs, and generally require very little maintenance
Bringing you all the benefits
Heat pumps as a sustainable technology offering customers a wealth of benefits, many of which they have in common. Each system, whether you’re considering an air source or ground source heat pump, has its own range of sustainable superpowers. However, both of them promise to deliver:

1. Savings
Energy efficiency, Eco-credentials & Cost Savings
Heat pumps use less energy than traditional heating systems by transferring heat rather than generating it.
By utilising renewable energy from the air or ground, heat pumps reduce greenhouse gas emissions and help lower your carbon footprint.
The efficiency of heat pumps often results in significant cost savings on energy bills compared to conventional heating systems like gas or oil boilers.

2. Reliability
Consistent performance with Comfort 12 months a year
Ground source heat pumps in particular provide reliable heating by drawing energy from the stable temperatures underground.
Heat pumps can both heat and cool, offering a versatile solution for maintaining indoor comfort in all seasons.

3. Home & Business Environment
Durability, Improved indoor air quality & Minimal noise levels
With proper maintenance – something the team here at UK Alternative Energy specialise in – heat pumps can have a lifespan of 15–20 years or more, offering a great return on investment. Heat pumps don’t rely on combustion, so there’s no risk of indoor air pollution or carbon monoxide emissions. Modern heat pump systems are designed to operate quietly, making them a discreet addition to your property.

The Science Behind the Technology
Heat pumps can efficiently heat and cool your home or business by transferring heat from one place to another, rather than generating it. They work on the same principle as a refrigerator, but in reverse when heating. By using electricity and leveraging renewable energy from the air or ground, heat pumps provide a sustainable and cost-effective solution for maintaining comfortable indoor temperatures year-round.
But how do the two main types of heat pumps, air source and ground source, differ operationally?
Air Source Heat Pumps (ASHPs)
These systems extract heat from the outside air – even in colder weather – and transfer it indoors to provide heating and hot water. During warmer months, they can reverse the process to cool your home. ASHPs are straightforward to install and are suitable for a wide range of properties and businesses.
Ground Source Heat Pumps (GSHPs)
These systems use underground pipes to draw heat from the earth, where temperatures remain relatively constant throughout the year. The captured heat is then compressed and transferred into your building. While GSHPs require more space and initial effort during installation, they offer exceptional efficiency and long-term savings.
Both types of heat pumps deliver impressive performance, are eco-friendly, and help reduce your carbon footprint. Choosing the right system for your property depends on factors like available space, installation preferences, and energy goals, all factors that our expert team of installers can advise you on.
