Introduction to Heat Pumps

The sun is an energy source and its heat is stored in the earth. It is this stored heat that is converted by our heat pumps into heating and hot water for your home. Part of the heat from the earth is fed into the heat pump through a heat-transfer medium and converted into higher temperatures for your heating. The heat pump produces far more energy than it consumes. For every kilowatt-hour purchased you receive a free contribution from nature comprising a further three to five thermal kilowatt hours, which are available as heating capacity. This is referred to as the units 'Coefficient of Performance' (COP).

Savings

There are possible savings of up to 70% on your annual heating costs with a heat pump vs. an oil boiler.

Compact Collectors

Solution for smaller gardens. An excellent solution for smaller gardens or for areas where drilling holes is not possible. The compact collector, which is two metres high, is very easy to install, it is placed vertically in the ground buried one metre below the surface and the best of all you only need approx. 40m².

The compact collector revolutionizes the possibilities of geothermal energy. When combined with exhaust air recovery only 40 square metre of garden is needed to provide geothermal energy for normal size house.

Ground Water Heat If you have a borehole well with a good flow of groundwater, it can be your new source of heat. A pump moves water to the heat exchanger in the heat pump. This produces heat for radiators and hot water. You can also bore a new well for groundwater heat. As well as obtaining a reliable supply of heat at a very low operating cost, you can also get water for your lawns and reduce your water consumption. The amount of work to be done in your garden is small.

How The Heat Pump Works

  1. As the heat transfer medium (spirit/water) circulates in a plastic hose, it is heated by the rock or the soil.
  2. The liquid heats the refrigerant, which evaporates.
  3. The refrigerant is then compressed in the compressor, causing the temperature to rise considerably.
  4. The heat is given off to the heating and hot water system of the house in a condenser.
  5. The pressure of the refrigerant is lowered in an expansion valve and it returns to liquid form. The liquid refrigerant returns to the evaporator.

Air To Water Heat Pump

How The Principle Works
An air / water heat pump takes its heat from the outdoor air and ensures great savings. There is no need for bore holes and ground collectors so installation is quick and simple and can be installed in any type of house.

This also means that the air-to-water heat pump is a perfect and highly efficient solution for areas where it is not possible to drill for rock heat, or where the garden is too small to install a conventional heat pump system. JAGTech Ltd can offer a very compact unit which does not require an indoor unit. This is very attractive for those applications that indoor space is at a premium. This form of heat pump is ideal for the retrofit application as it has a reduced capital cost to that of ground source heat pumps.

The benefits to this style of installation include:

  • No indoor unit required
  • Available for all domestic applications
  • Built in weather compensation
  • Can be installed in conjunction with all other heat sources
