Heat Recovery

Heat recovery systems use heat exchangers to capture heat energy, otherwise very often wasted, and reuse it by returning it to systems or processes, including heating space and/or water.

Of the many different types of heat exchanger available, the Eureka Permanent Transfer System® uses one of the most efficient, a reverse flow coil, to extract heat from refrigeration and chilling systems. By diverting the refrigerant from between the compressor and condenser, the PTS transfers heat to stored water, which can then be used either directly or as a support for traditional heating systems. The process also super-cools the refrigerant before returning it to the chilling system, thereby improving performance and/or reducing power consumption.

The PTS is just one of a number of Eureka systems tailored to work with chilling systems from 4kW upwards. As a rule of thumb, for every kW of cooling capacity, we can provide 20 litres of water heated to 55°C for every hour of operation. For example, a 12kW chiller, operating for 10 hours every day for a year can provide 876,000 litres of hot water, and this from heat normally simply vented to the atmosphere.

Whilst fitting with new plant is ideal, retro-fitting to existing plant is viable in most cases. Cost benefits of a heat recovery system depend largely on the type and scale of the installation, but heat recovery can give substantial long-term energy savings. It often reduces the need to generate heat in the first place, making further energy and cost savings. More information is available from the links below:

Suitability

A feasibility study must be undertaken, and independent expertise should be sought to ensure the viability of such a system.

Good Housekeeping

If a heat recovery system is already installed, ensure that it is functioning efficiently by regularly checking it.

Types of Equipment

There are several options for recovering heat, including plate heat exchangers, thermal wheels and run-around coils.

Uses of Waste Heat

Waste heat can have many uses depending on the requirements and the grade of waste heat.

Sources of Waste Heat

There are a number of items of plant common to many sites which all have the potential for waste heat recovery.

ESEA Ltd are heat recovery system suppliers based in Peterborough and supply heat recovery systems across the UK, so if you are interested in the possibilities or would simply like to know more we will be pleased to discuss the options with you and, as appropriate, conduct a survey without obligation.
