Why I replaced my new gas boiler with a heat pump - FORESIGHT

In a heat transfer process, this temperature difference will vary either with position or with time. The general heat transfer equation was thus developed as an extension to Newtons law of cooling, where the mean temperature difference is used to establish the heat transfer area required for a given heat duty.

and boilers can typically operate at recirculation rates of 20-25 percent without adversely affecting boiler heat transfer and efficiency. This comparison illustrates that the increased flow of LFG as compared to natural gas will not adversely affect boiler operation, although the burner, controls, and fuel train will require some modifications
