The preferred technology

IEC Heat Solutions are approved installers of ground source heat pumps manufactured by Oilon. Oilon are an international company who are based in Finland, with production facilities on 3 continents and a global dealer network.

The Oilon Chillheat pumps have proven themselves to be versatile and reliable, and the level of support and customer service they provide makes them an ideal partner for IEC Heat Solutions.

The Oilon pumps were selected for several factors which are critical to the operation and feasibility of ground source heating installations:

Key features

  • Excellent efficiency even at high temperature
  • Flexible automation & remote operation capabilities
  • Excellent part load run conditions
  • Compact size
  • Sound proofing enclosure for low noise & low vibration
  • Every unit subject to a factory run test prior to shipment
  • Ability to heat and cool using the same GSHP unit

IEC specialise in the modelling, installation and maintenance of the Oilon Chillheat ground source heating systems, and will help you to understand and operate your heat pump from commissioning onwards.  As always, our customer service and maintenance teams are on hand to ensure that your pump operates to its fullest potential.


Basic principles of heat pump technology

Take a look at this diagram to understand the basic principles of heat pump technology

  • The ground source heat pump operates by collecting energy from a ground loop heat source, and using this to heat the refrigerant liquid inside of an evaporator.
  • This liquid becomes a gas, which is pushed through a compressor to heat it to a high temperature.
  • The gas is then sent to a condenser, which cools the gas by heating water for distribution to the heat use.
  • The cooled gas returns to its liquid state, and is sent back to the evaporator to begin the process again

Ground Source Heat Pumps are run by electricity alone, and so do not rely on fluctuating fuel supply issues.  This electrical power demand means that the Co-efficiency of Performance (COP)  of the unit is of paramount important- meaning that the ratio of heat generated (kWh) for every unit of electricity used within the process should be as high as possible.

IEC specialise in maximising this COP to provide the greatest amount of heat or cooling at the lowest possible cost.
