Heat pump: ground source or air source. That is the question everyone
is asking. Let’s focus on benefits and disadvantages of each technology. 

Advancement in technology has contributed to cost reduction of efficient heating and energy-generating solutions. At the same time, these solutions are environmentally friendly. In times of worsening climate crisis,
actions in to reduce our carbon footprint are necessary.
Heat pumps are a great proposition for people who want to bet on modern, efficient, green technology.

What is the difference between heat pumps?
Ground source or air source – which one should I choose?

Ground Source Heat Pump – how does it work?  

To answer that question we should explain how this technology is extracting energy.
In essence, ground source heat pump is taking
solar energy stored in the ground.

After the energy from the ground is extracted,
ground source heat pump transfers it to a heat exchanger where the energy is converted to the heat.
It can also operate in reverse cycle
and provide cooling for your home.

Air Source Heat Pump – how does it work?  

The operation of the air source heat pump does fundamentally differ
from a ground source.
Energy is not taken from the ground but from the air.
It is then transferred to internal circulation system where it is converted into the heating
or hot water for your home.
It can also produce cooling when necessary.

Air source heat pumps does not require as much space as ground source heat pumps.
That’s why they are often chosen
when large grounds are not available
or drilling a borehole is not feasible.

Ground Source or Air Source Heat Pump – which one is better?

It is difficult to categorically say which heat pump is better:
ground source or air source.
First of all, ground source heat pumps require large areas
for ground loop installation.
Otherwise borehole can be utilized providing
that heavy machinery can access borehole location.
Thus, they are primarily suitable for properties with large garden.
You will also need space to fit the heat pump unit indoor.
The reward is the highest possible efficiency of all types of the heat pumps. Ground Source Heat Pump does not affects
the overall appearance of the building.
It will also maintain highest efficiency despite lower outdoor temperatures.

Air source heat pump is a little different here.
Must be installed on outside.
Installation of this type of heat pump is cheaper and less demanding.
You do not have dig through the ground
but the heat pump is visible outside your house.
It requires very little space but will loose some efficiency in very cold weather.

Exhaust Air Heat Pumps – solution smaller house or flat

It is also worth considering
the exhaust air heat pump for smaller houses
or flats without any outside space available.
It takes the least space
of any other type of heat pump,
making it a frequent choice among our customers.

How does it work?
This type of heat pump extracts heat
from the exhaust air
of the building to transfer it to the supply air
or heating/hot water system.
It is combining mechanical ventilation with heat pump. It requires ventilation ducting to be installed
and is brilliant way to install renewable energy source
in homes without any garden space.

We specialize in all types of heat pumps listed above!

We are looking forward to answer your questions
and to provide professional advice on your specific requirements.
