Condensing-Boiler Tips

September 2007
Heating/Piping/Air Conditioning Engineering;Sep2007, Vol. 79 Issue 9, p72
The article offers tips for maximizing efficiency of condensing boilers. Low heating-water return temperature (HWRT) enables boilers to operate the majority of time in condensing mode. It is advisable to use industrial-quality pressure-independent control valves at coils. Boiler capabilities should be considered when choosing a piping configuration.
