85 Efficiency Natural Gas Boiler

is high efficiency gas boiler worth the investment?

A high efficiency gas boiler (gt;90%) must have the flue gas condense in order to achieve that efficiency. The flue gas will only condense when the return water temperature is 120 degrees or less. An ordinary system has return water temperature much higher than this, because this is the temperature for which your radiators are sized (typically
