The sun sends the earth 174,000 terawatts of free energy – every day.
It makes sense to use this gift of nature to heat and cool our homes.
Thermia heat pumps
Heating in winter and cooling in summer
The sun has been heating our planet for billions of years.
The earth is slow to give that heat back.
That’s why the ground temperature remains at a constant 0 to 10 C, whatever the season and however cold the weather.
This is enough to heat a house in winter and cool it in summer.
The earth accumulates solar heat,
keeping the temperature
below ground at a constant 0 to 10°C
Warm in the winter
The heat pump concentrates low-grade heat
from below the ground and raises its temperature.
This heat is then transferred to the house’s energy
distribution system – unusually radiators, hydronic floor
heating or fan coils.
Ground accumulates solar heat,
so the temperature underground
is from 0 to 10ºC.
Cool in the summer
The heat pump collects heat from the house
and deposits it into the ground,
This is more cost-efficient than traditional
Ashgrove’s team of experts specified, designed and sized the heat pump using Thermia Heat Pump Calculator software.
The hotel and spa are heated by Thermia ground-source heat pumps. 18 Robust heat pumps with a total capacity of 715 kW provide heating, cooling and hot water to 24,000 m2 of hotel rooms, the spa, offices, shops and apartments.
When the Carlsson family moved in to their new home, they were using an oil-fired boiler and a pellet stove to heat the house. The boiler was approaching the end of its working life and the pellet stove required a lot of attention.
Energy consumption for heating purposes dropped to 2847 kWh and the heat delivered to the house was 9373 kWh, so 70 % comes from thin air and is renewable energy. CO2 emissions, originally 4 240 kg dropped to 2 070 kg, this is a massive 51 % reduction (2,170 kg CO2).
Low carbon heating system
This 185 sqm bungalow was built in 2016. It is completely heated by underfloor heating. A 9kW Atec air source heat pump with a Total 180 litre cylinder has been running since March 2017.
“I’m very happy with the system. The consistent heat is great and the house is so comfortable I am delighted. I am starting another build in the near future and we will certainly be back to O’Brien Brothers and Ashgrove. Mike has been very helpful and is always contactable. It has been hassle free.” Noel Costello

"…we wanted to simplify our daily life. That is why we wanted to have a heating system that would take care of itself as much as possible. And we don’t need to do anything with our heat pump…" Mattias Carlsson
