Hot Water Production

Reduce Energy Costs

Heated water can be fed into both local and district heat systems to cover basic heating requirements. It can also be used as the heat supply of individual facilities, such as hospitals. Peak heat demand can be met through a buffer and a peak boiler plant. Gas engines can raise the efficiency of cogeneration plants to over 90 percent (40 percent electrical and over 50 percent thermal energy).

Calculating the Economy of a CHP Plant

In the evaluation of the economy of a CHP plant, the energy costs saved and/or revenues from the production of electricity and heat are compared to the necessary capital investment. The electricity generated from the plant can either be fed into the public grid or used for the operator's own supplies, economically a significantly more attractive proposition. This makes it possible to include electricity savings in the equation as well.
