Simple Steps for Recovering Lost Heat

It is perhaps an unfortunate fact that often 80% of the heat we produce in our homes or in industries is lost through a necessary ventilation system. This generating of extra heat is, of course, an expense we could all do without but not having adequate ventilation could have higher expenses in aspects of health and of course safety. Today, however, there is an option which does not eliminate the need for ventilation but uses the ventilation system to reduce energy costs and that option is to add a heat recovery system to our existing ventilation system.

When fossil fuels are used to create heat for whatever purpose, the fumes which are given off can be hazardous to our health and so need to be adequately ventilated. However, those ventilated fumes are now thought to be one of the main causes of global warming and so many industries are faced with a dilemma. The dilemma is as to whether or not to replace their existing ventilation system with a more efficient system in order to meet tighter government regulations concerning CO2 emissions or switching to renewable energy which does not give off such harmful emissions. Both options though can be expensive but more recently another option has become available and that is to add a heat recovery system to your existing ventilation system as this can both help to reduce emissions and reduce costs at the same time.

Heat Recovery System

A heat recovery system is a system which collects the heated air which is to be exhausted and by transferring it to a heat transfer unit, allow that otherwise exhausted heat to be used to heat boilers or just incoming, cooler, fresh air. By using this heat which would have otherwise been dispersed into the atmosphere where it would contribute to global warming, it is instead ‘recycling’ it and using it productively. It is estimated that with a professional grade heat recovery system like the ones provided by Exodraft, the world’s leader in heat recovery systems, a saving of as much as 20% can be expected in future energy bills. Although perhaps not completely eliminating emissions escaping into the atmosphere, the system should help any industry to meet the stricter emission levels being set by their governments and do so without the cost to replace the existing ventilation or heating systems.

Cost and Savings

Although the heat recovery system does have a price, as it is an addition to your existing system, it is cheaper than a replacement system and experts estimate that its cost can be recouped by cheaper energy costs in the future, over a period of only 2 years. After that 2 years of course, as the heat recovery system needs minimal maintenance, those savings convert into profits or in the case of a household, savings.

Installation and Compatibility

As a heat recovery system is designed to be an addition to an existing system, minimal disruption is caused during installation. Today there are recovery systems which have been designed for use with almost every existing ventilation system in use and so compatibility is assured. Also as the recovery system has been designed as an addition and not a stand-alone system, it takes up little if any working space as the main units, such as the heat transfer unit, have been designed so as to nicely fit in potentially vacant spaces such as cupboards or even ceiling voids.


Although the system requires minimal maintenance, it may be necessary on occasions to clean the heat transfer unit but in order to reduce disruption and cause inconvenience, most of the larger suppliers of the systems will provide replacement units for cleaning periods, ensuring no loss in production in industry and no cold nights in the home.
