Yes, even if you don't have to use one.
Typical condensate from a condensing boiler has a pH level of 3.2 to 4.5, which is acidic enough to leave stains, kill shrubs, and eat away cast iron drainage systems. In fact, in some municipalities condensate neutralizers are required by law when draining condensate into home plumbing systems.
Condensate production can be estimated based on one gallon per hour for every 100,000 BTUs of input, so make sure the size of the neutralizer is correct. Condensate neutralizers contain ½" marble or limestone chips that are readily available at any home store. Our neutralizers are clear, to allow consumers to see if the marble or limestone chips are low and need to be replaced. So remember to include a condensate neutralizer when designing a system. Not only is it good for the environment, it may also be required by law.
