About transen

‘GREEN HEAT’ is a term first addressed in the late ‘90s that addressed a significant opportunity for the ‘global village’ to increase the use on renewable energies.

The low-grade thermal applications that can be met by Green Heat represents the largest secondary end-use of energy in the world.


Since 2000 the senior personnel in Transen Sustainable Energy Systems have been involved with the design, development and manufacture of a range of water-to-water and water-to-air ground source heat pump systems. Single and three phase units are produced and tested at their factory in Coleraine, Northern Ireland and installed in residential and commercial projects throughout the UK

The company’s policy of ongoing product development has evolved whereby a prospective client is offered a ‘one stop shop’ package consisting of circulating pumps, ground loop systems with manifolds and stainless steel storage tanks, each designed to service the building’s space heating and hot water requirements.

The heat pump technology needs only an electricity power supply to produce space heating and cooling and domestic hot water. With the Transen unit having a high Co-efficiency of Performance (CoP) as against other forms of central heating the yearly energy costs to run such a system, with the correct sizing and programming, can be reduced by as much as 40%. Carbon emission is zero.

Additionally, according to a report recently published by NB Environment, in the United States, green buildings that achieve a high-energy efficiency Energy Star rating are selling at 27% more per M2 than buildings that fail to achieve this standard. Occupancy rates in energy efficient buildings were 92% compared to 87% for those with less efficient standards.

In the UK, the payment from the power generation companies for Renewable Obligation Certificates (ROCs) for energy produced by hydro and wind generation is to be increased substantially.

In theory a group of buildings, residential or commercial, constructed to a passive build specification, serviced by a wind or hydro generator and having a ground source heating/cooling system installed could achieve a negative power cost system. With the payment of carbon credits, a source of revenue could also be available to a developer, housing association or building occupant.
