The author provides information about boilers. He mentions that pumping is one of the factors that has to do with actual operating efficiency of the boiler, where an oversized and overpumped boiler will never get above 88%. He notes the key to saving energy which is to go low and slow with both the water temperature and flow rate, Thus, he states that every boiler must have a control that watches how cold it is outside and adjusts the temperature of the boiler accordingly.
