represents a significant opportunity for improved cycle efficiency. Overall boiler efficiency becomes primarily a function of the final flue gas temperature, and will typically be in the range of 80 to 85% when the excess air ratios are near optimal. In principle, one should calculate the individual cost components rigorously for the site-specific

Learn MoreThe simplest way to calculate the size of electric boiler for your home is to times the number of radiators you have by 1.5 to give you the number of kw you need. Consult your boiler installer as to the correct size of electric or gas boiler, as buying an overly-powerful boiler leads to

Learn MoreMar 23, 2021 · In the context of current operating costs, natural gas might prove the least expensive option when it comes to central heating fuel sources, especially if one uses a condensing boiler, which is capable of converting almost 90% of the fuel it consumes into heating. Nonetheless, it is not a secret anymore that gas prices will go up in the near
