Heat Pumps from Energy Superstore
What exactly is a heat pump?How does it work?
The basic principle is as simple as it is brilliant: take the free energy that exists in the air and ground, and convert it into heating for a house. But things are rarely this straightforward. As the popularity of heat pumps has grown, so has the number of options. Today homeowners who have
decided to do something about their heating costs can find it difficult to get an overview of the world of heat pumps.
There are 2 main types of heat pumps:
Air to Water Heat pumps (IVT AirX)
Geothermal Heat pumps (IVT Greenline)
Horizontal Loop method
Vertical Loop method
With an air source heat pump there is no need to dig or drill. Instead the energy is sourced straight from the surrounding air. For a complete system that covers all your heating requirements, including hot water, you need an air/water heat pump. These are by far the most popular Heat pumps on the market due to their simplicity and cost effectiveness.
Lower investment cost.
No impact on the ground.
No large plot needed
The vertical ground loop collects solar energy stored in the bedrock. A hole is drilled into the bedrock and a pipe is installed to a depth of between 100 and 200 metres. The exact depth depends on the house, size of heat pump and surrounding conditions.
A common myth about heat pumps is that they will not work if several homes in the neighbourhood have already drilled down to the bedrock. This is definitely not true! The earth’s ability to store heat is almost endless – there’s enough heat for everyone.
A large plot is not necessary
Small impact on the plot
The horizontal ground loop collects solar energy stored in the ground, near the surface. If the bedrock is too deep down, or if you don’t want to drill for other reasons, this is a good option.
The loop is buried about one metre below the surface, and energy is extracted from the ground. The length of the loop depends on the house, the size of the heat pump and local ground conditions.
Lower installation cost compared to vertical ground loop
Can also be used to extract heat from lakes.
A groundwater heat pump collects energy from the groundwater.The water is pumped up from a water borehole to a heat exchanger, where the energy is recovered. The water is then discharged back through another well. This solution can be the best choice when groundwater is readily available.
Groundwater maintains a relatively high, even temperature, year round.
Heat pumps – a smarter use of energy
A heat pump from IVT creates a comfortable indoor climate in your home. While it’s supplying your home with heating, hot water and cooling, you can reduce your energy consumption
by up to 75 per cent. When it’s time to select a new source of energy for your home, a heat pump from Energy Superstore means you’re also contributing your share to
help the environment.
Heat Pumps are Economical
Solar power generates large amounts of FREE energy that is stored in the air, ground and ground water.
A heat pump will help you unlock this free energy.
By extracting this heat efficiently you can reduce your energy consumption considerably. The savings are often large enough to pay for the investment in just a few years.
Heat Pumps are Comfortable
A heat pump requires virtually No maintenance or refilling of fuel, and it’s very easy to operate. You can adjust your indoor temperature with just a touch of a button. The heat pump does not take up much space, normally only about as much as a fridge.
Heat Pumps are Eco-friendly
By choosing a heat pump you help to reduce the impact on the environment.
The technology is well-tested and the EU classifies heat pumps as a renewable source of energy. The amount of solar energy the heat pump extracts is much greater than the amount of energy it consumes.
COP – efficiency in specific conditions.
As a buyer it´s important that you find out how efficient a heat pump is. Most
manufacturers present this information in terms of COP (Coefficient of Performance).
In specific test conditions, an assessment is made of the heat pump’s ability to supply
heat, relative to the amount of electricity required to extract it. If a heat pump has a
COP of 4, this means that in the specified test conditions it produces four times more
energy than it consumes. Consequently the extracted energy makes up three quarters.
Be careful when comparing values
It’s important to be conscious when comparing a heat pumps efficiency. Measuring the COP in specified test conditions, without calculating the energy consumption for all the components in the system (e.g. circulation pumps), can produce what seems to be very good values. But a measurement
should not be done just to support a manufacturer’s marketing. It should give homeowners like you a more correct picture of how efficient the heat pump is, over time.
Annual efficiency – the real measure
A far more accurate measure of a heat pump’s performance is its annual efficiency (seasonal performance factor). This incorporates the whole year, including the warmest and the coldest
periods, as well as the production of hot water. Other factors that affect the overall result include house size, geographical location and number of residents.
