By the fast development of OSB geothermal heat pump, let’s look back a little to see why we are more focusing in geothermal heat pumps now.
All heat pumps work in a similar way, by extracting heat from their surroundings (from the ground, the air, or from water) and converting it into useful energy which can heat your home. They need some electricity to run, but because they are extracting renewable heat from the environment, the energy output is much greater than the electricity input, making them an energy efficiency method of heating your home.
A ground source heat pump is typically more efficient than an air source heat pump, and it has better payback. However, a ground source heat pump is more expensive to buy and install at the beginning.
Especially when you consider the time of year you would typically rely on your heat pump the most – when temperatures drop during the winter months – it’s even easier to understand why the ground source heat pump wins in terms of efficiency. The temperature of the ground is fairly fixed at a constant 10 - 130C all year round, so a ground source heat pump remains consistently efficient throughout the year, unaffected by seasonal changes.
Below is a reference table as a comparison between three different type of heat pumps:
As from the chart, we know that geothermal heat pump is the most efficient type of heat pump among 3 different type, even though the cost is most expensive!
There are many factors to consider when choosing a heat pump.
Not only do you need to weigh up the costs and efficiencies of each system, but also the practicality of the installation, available space in your home, noise and any required planning permissions.
According to our consumer research, most people cite energy bills as one of the main reasons why they install energy efficiency upgrades at home. People with cold homes are the most likely group to look into this, as difficulty in heating rooms is the biggest single predictor for householders considering or planning energy saving action. In this case, geothermal heat pump no doubt is your prior choice.
It is time to replace your heat pump with geothermal type now !
