how to maintain your condensing boil

How to Maintain Your Condensing Boil

While the effectiveness of the condensing process varies depending on the temperature of the water returning to the boiler, it is always at least as efficient as a non-condensing boiler. The condensate produced is slightly acidic (3-5 pH), so suitable materials must be used in areas where liquid is present.
