Purchasing Energy-Efficient Large Commercial Boilers .

A minimum turndown ratio of 5:1 is recommended for gas-fired, hot-water boilers. This is particularly important in condensing boilers that run more efficiently at part load. Low mass : Because boilers cycle on and off and it takes time to bring a high-mass boiler up to operating temperature, using low-mass boilers will reduce energy consumption.

Using Water Heaters for Radiant He

Typical boiler systems use a design temperature of 180°F or higher, which produces scalding hot surface temperatures at cast radiators and convector units and is too hot for radiant floor applications. Lower water temperatures are becoming more common because they are safer for children and and produce a more even and comfortable heat.
