How to Buy a New Boiler | The Family Handyman

2021-1-6 · A boiler's energy efficiency is rated with an "annual fuel-utilization-efficiency" (AFUE) score, which stands for and indicates the percentage of energy the boiler converts into heat. By federal law, a new boiler is required to have at least an 80 percent AFUE rating, but old boilers may have an AFUE rating between 56 percent and 70 percent.

Induction boiler – Infinity SAV

The boiler works by means of an induction coil, which creates a variable magnetic field using current of 50 Hz frequency. The metal maze system, which intensifies the heat exchange, is heated by means of magnetic reversal and practically without loss transfers the released energy to the heat carrier.
