the approximate efficiency of water tube boiler without heat recovery is

CHP Combined Heat Power Engines

The environmentally friendly organic working fluid is turned into vapor by application of a heat source in the evaporator. The organic fluid vapor expands in the turbine and is then condensed using a flow of water in a shell-and-tube heat exchanger (alternatively, ambient air can be used for cooling).

Estimating the Cost and Energy Efficiency of a Solar …

Another solar water heater performance metric is the solar fraction. The solar fraction is the portion of the total conventional hot water heating load (delivered energy and tank standby losses). The higher the solar fraction, the greater the solar contribution to water heating, which reduces the energy required by the backup water heater.
