The whats, hows and whys of NOx emissions in commercial

The latest limits from Ecodesign in September 2018 reduced the emission level on all natural gas boilers up to and including 400kW to a level of 56mg/kW. This changed from net figures to gross. The previous best classification was Class 5 and stated at 70mg/kWh net. 56mg/kWh gross converted is 62mg/kWh net, so a reduction has been made.

Hot Oil Heating vs Steam Boiler Systems for Tank Heating

Performance. In terms of performance, hot oil systems do better than steam heating. Thermal fluid heating is more reliable, providing more consistent heating and accurate temperatures. They also have a high degree of customizability, allowing for optimal performance. Circulation, or in-line, heaters are key components in thermal fluid heating.
