efficiency of water tube boiler

Is a high efficiency, condensing gas boiler the best

The biggest difference between condensing boilers and "conventional", non-condensing boilers is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation.
