Heating and Hot Water - Energy Saving Information | YouGen

System boilers (also known as a sealed system), like conventional systems, work by storing hot water in a cylinder. However, the hot water is pumped through the heating system, and does not need a feed and expansion tank in the loft. The pros and cons are similar to a conventional boiler, but the installation is quicker and more efficient.

For example in the scheme shown in Fig. 19.2, an industry requires 24 units of electrical energy and 34 units of heat energy. Through separate heat and power route the primary energy input in power plant will be 60 units (24/0.40).If a separate boiler is used for steam generation then the fuel input to boiler will be 40 units (34/0.85).If the plant had cogeneration then the fuel input will be

This very much depends on the size of the system, how often it is used, and chosen fuel type. Larger boilers have a higher output and use more fuel, so a 25kW boiler will use 25% of the fuel that a 100kW boiler will use if they are both ran at their full output for the same amount of time.
