Whether in the home or at work good energy management is essential to reduce costs and to protect the environment. This is why TEC Heating Controls, a long established leader in the heating industry, have introduced the Heat Manager system onto the market. The Heat Manager system works on the concept that you only have heat where you want it, when you want it. In principle you wouldn't walk into your home and switch on all your lights- nor would you switch on an entire cooker when only one ring is required.
