Which Heat Pump Is For Me?

Which Heat Pump Is For Me?

Have you got a self-build project in the pipeline? Or simply looking to replace your current heating system in your property? The chances are, you’ve probably come across Heat Pumps in your research at some point along the way. If you are just having issues with your system make sure to try and do a San Diego air conditioning repair (this page). It can save you money in the long run.


So, what are Heat Pumps? Heat Pumps are an ultra efficient and highly sustainable way for you to heat your home, but which one is the perfect match for you? There are quite a few factors that will determine which heat pump is most suitable for your property, but hopefully by the end of this blog, you will have found the one for you.


Heat pump technology is more advanced now than ever before, with the introduction of inverter driven technology, heat pumps are no longer fixed output, glorified air-con units, they are in fact the most efficient way to heat your home and provide all your hot water. At Hero Renewables we only like to install products that we know will stand the test of time, whilst performing reliably and consistently all year around to meet our customers’ needs. The Hero Aquamaster was one of the first heat pumps to bring inverter driven technology to the UK market. By inverting the compressor within the ground or air source heat pump, the speed of the refrigeration cycle automatically adjusts, eliminating energy losses caused by stopping and starting. Variable flow temperature can save 30% or more when compared to a fixed flow, minimising lost energy and maximising your homes energy efficiency, whilst extending the life of your heat pump at the same time.


All of the heat pumps that Hero Renewables offer our clients are all inverter driven, this means that we can ensure our customers are going to have the most optimised and efficient system as possible. Our heat pumps also come with a 7 year warranty which covers all parts of the unit, as well as two years free labour on our service contract from Hero Care Plan. We design our systems to last a minimum of 25 years, however they are known to last much longer.


Comparing efficiencies between ground and air source heat pumps can get a little tricky. Ground source heat pumps use the energy stored in the ground from the sun’s rays and rainwater, collected either through pipes laid in trenches at least 1 meter into the ground, or from boreholes up to 100m deep! Air source heat pumps must take heat from the air, unfortunately in the UK we are not blessed with constant air temperatures this means the air source heat pumps needs to work a lot harder in order to run its refrigeration cycle in colder months. Despite an Air Source Heat Pump being able to extract energy from the air form temperatures as low as -25°C, running costs are marginally increased during winter, unlike a ground source, as temperatures remain around 10°C 1 meter down in the ground. The inclusion of underfloor heating can also have a significant effect on the efficiency of the system, as detailed in the chart below.

The size of your property is something to always bare in mind. Because Heat Pumps work best providing a low flow temperature, the less work the heat pump has to do in order to keep a constant heat, the better. If for example you were looking to heat a smaller, well insulated property, an air source heat pump would comfortably manage to distribute enough heat to keep the required temperature throughout. If you were trying to heat a larger, less insulated property it would be much more cost efficient to install a ground source as your running costs would be significantly lower.


So why not go for the more efficient Ground Source Heat Pump? Due to the ground works required in a ground source heat pump installation, they require an area of land around the building and a higher capital outlay to complete the groundworks. When compared to an Air Source Heat Pump, which only requires very little space outside of a property, therefore it can prove a more attractive for projects limited by a budget, and lacking land area to complete groundworks.


The latest news regarding Heat Pumps is the recent improvements to the Domestic Renewable Heat Incentive tariffs, the payments that you’ll receive for generating renewable heat from a Ground Source Heat Pump is 19.55p/kWh and for an Air Source Heat Pump 10.02p/kWh. So for an average 3 bedroom detached property you would expect to see RHI payments totalling £31,475.50 for ground source and £16,132.20 for air source over the 7 year RHI period.
