Boiler – Fundamentals and Best Practices
When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat

WOAH! Is that hot water boiler sized properly? | US Boiler
Jul 21, 2019 · The shorter the cycle the less efficient the boiler becomes as standby losses increase. We don't want to heat the system water too quickly. Smaller inputs and slower temperature changes are key to greater comfort and higher efficiencies. The only way to properly size a hot water boiler is by performing a heat loss calculation.
