HEAT PUMP PROS & CONS
We look at the main heat pump options, along with the key factors that will help you decide if this efficient tech suits your project
Vaillant’s aroTHERM split is a Quiet Markapproved, lownoise air source heat pump that’s available in a wide range of outputs
Heat pumps are a modern, low-carbon space heating and hot water solution. They take warmth from low-grade sources (the air, ground or water), compress it to boost temperatures, and then distribute it around the home. Crucially, heat pumps produce more energy than the electricity required to run them – making this piece of kit an appealing choice for a range of projects – especially those with sustainability as a priority.
What makes heat pumps efficient?
Heat pumps work on the same principle as a refrigerator, but in reverse. Depending on the type of installation, energy is taken from the ground, air or water in a collector fluid known as a refrigerant. It’s then passed into the heat pump’s compressor, which pressurises the fluid into a gas, increasing its temperature. This gas passes through a heat exchanger, which extracts the warmth for use in your home’s heating and hot water system. You’ll also need a cylinder to complete the setup.
Nibe’s Build It Awardwinning PV-T heat pump is a truly innovative setup, combining a rooftop solar PV system with a GSHP appliance to enable installation in properties that don’t have spacious gardens
