The role of the design and operation of individual heating

Oct 15, 2016 · Natural gas boilers can be nowadays divided into two categories: high efficiency boilers (LTB) or condensing boilers (CB). Both technologies have a common operation basis, being the difference that condensing boilers recover part of the latent heat content of the exhaust by condensing their vapour water content through heat exchange with the water returning from the load side.
