      • What types of renewable energy heat pumps are there?

        Heat pumps can use a range of heat sources and operate through a wide range of temperatures from 40°C up to 130°C. They can be used in many applications and make use of any suitable heat sources that are available. Heat pumps can be categorised into four key types: air source; ground source; water source; and high temperature – for use in industry.

        Blueflame ASHP - Types of Heat Pump

        There are four main types of heat pump

        1. Air source heat pump
          - Air to air :
          produces warm air which is circulated by ventillation units to heat your home; also for cooling in warmer weather.
          - Air to water :distributes heat via radiators or underfloor heating and also heats your hot water
           
        2. Ground source heat pump
          Requires pipes to be buried in the garden to extract heat from the ground to heat radiators, underfloor or warm air heating systems and your hot water.
           
        3. Water source heat pump
          An alternative to a ground source system extracts heat stored in water or a lake
           
        4. High temperature heat pump
          These are used in industry for high grade, high carbon intensity heat processes, such as drying, pre-heating and distillation. A waste heat interface recovers heat from site processes or CHP plant and supplies it to the heat pump, which then upgrades the heat to a higher temperature. This can be used in processes, to generate low pressure steam, or provide high temperature hot water.

        Air to Water Heat Pumps

        Most of the heat pumps installed in the UK are air to water heat pumps, which provide both space and water heating. They can be installed on almost all properties, including flats. A normal pump is about the size of a fridge, and you just need a place outside where it can be fitted to a wall or placed on the ground, with space around it to get a good flow of air.


        All air source heat pumps do produce some noise, as they contain a fan, but the modern ones are much quieter which is rarely a problem.

         

        Air-to-water heat pumps are simple to install and require little maintenance..They are an economical replacement to oil fired, coal and electric central heating, and a boon if you don’t have mains gas. And, as you won’t need a boiler, it frees up space in the home too. (Although electricity is needed to power the pump, extracting the heat from the outside air, a limitless renewable resource, even in temperatures as low as -18°C, far outweighs the cost of the electricity.)

        Air to Air Heat Pumps

        Air to air heat pumps are essentially air conditioners that work in reverse. The biggest benefit is that they have the ability to keep you nice and cool in the hot summer months and warm and toasty during the long cold winter.

         

        It pumps heated air into your house, therefore, you need another mechanism to heat your water. This is essentially seen as a hybrid system - which is a heat pump and traditional boiler combined. The concept being that the heat pump does most of the work, but falls back on the boiler to help out in particularly cold weather, when the heat pump may struggle.

         

        However an air to air heap pump hybrid does have some advantages. The pumps are cheaper and have a good efficiency. Since they don’t use radiators, you won’t need to install bigger ones, although you may need ducting (pipes) in order to carry the hot air around to different rooms.

         

        Another big benefits of an an air to air air source heat pump is their energy efficiency. These systems use electricity to move heat from the air outside to the air inside, rather than generating heat through the use
        of fossil fuels. This means that they can provide heating and cooling at a much lower cost compared to traditional systems.
         

        In addition to being energy efficient, air-to-air heat pump systems are also very cost effective to install. They do not require the installation of any additional fuel lines or tanks, as they solely rely on electricity to operate. This makes them a good choice for homes that do not have access to natural gas or bottled gas.

        Ground Source Heat Pumps. Blueflame ASHP

        Ground Source Heat Pumps 

        Ground source heat pumps are the most energy efficient but, due to the cost and complexity of installation, are better suited to new builds during the later construction phases

         

        Ground source heat pumps (GSHPs) use pipes that are buried underground to extract heat from the ground, which is then used to heat radiators, underfloor or warm air heating systems and hot water in your home.

         

        A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. As the ground stays at a fairly constant temperature under the surface, the heat pump can be used throughout the year.

         

        The length of the ground loop depends on the size of your home and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.

         

        More details can be found on the Ground Source Heat Pump Association website.

        Water Source Heat Pumps. Blueflame ASHP

        Water Source Heat Pumps 

        A water source or lake heat pump effectively works in the same way as a ground source heat pump. By using heat stored in the lake water and lake bed. The collector circuit is laid on the bottom of the waterway and carries heat to a waterside home. Using heat from water reduces energy consumption in an efficient way.

      • Is an air source heat pump right for my property ?
      • Air Source Heat Pumps Compared to Ground Source Heat Pumps?

        Three important differences ...

        The installation

        Ground source heat pumps generally require a large garden or piece of land within which to be installed. Alternatively they can be installed in deep boreholes - as such both types of installation results in excavation costs before the physical system is integrated, within the property. The condensing unit is usually quite large and is sited inside of the premises.

        Air source heat pumps however do not require any intensive installation, and the condenser unit is simply sited in a box on the outside of a property. .

        The efficiency

        The efficiency, or the measure of the heat energy output per kW of electricity, is stated as the COP (Coefficient of Performance) or SCOP (or Seasonal Coefficient of Performance — the SCOP is the average COP over a defined period of time such as a year). A typical 'SCOP' figure for an air source heat pump might be 3.2; the comparable figure for ground source heat pumps is more like 4, so for every 1kW of electricity, 4kW is generated. So ground source heat pumps appear to be slightly more efficient. However as the compressor and the refrigerant is very similar in both systems you need to check the temperature of the heat source, so the ground and the air. Towards the end of the heating season (December onwards) the ground could be colder as the heat is extracted. If the air temperature is then warmer than the ground temperature then it can be argued that the ASHP could be more efficient. Geographical location and ground condition and important when making this choice.
