Is the condensate from boiler toxic?

The condensate expelled from a condensing boiler is acidic, with a pH between 3 and 4. Condensing boilers require a drainpipe for the condensate produced during operation. The acidic nature of the condensate may be corrosive to cast iron plumbing, waste pipes and concrete floors but poses no health risk to occupants.

In this way, how corrosive is boiler condensate?

Carbonic acid is a weak acid, but as the condensate water is pure, this weak acid reduces the pH significantly, often in the range of 5-6. At this low pH, the condensate water is very corrosive to carbon steel piping.

Also Know, is the plume from a condensing boiler dangerous? "The condensing boiler plume is a nuisance." Although it might bother some homeowners, the accumulated plume is not a problem at all. It actually proves that the boiler is working as intended.

Likewise, people ask, how much condensate does a boiler produce?

A general rule of thumb, 3.5 litres of condensate is produced for every 30kw of input providing the boiler is operating in full condensing mode. A boiler having 30kW of input operates for 1200 hours annually will produce approximately 4200 litres of condensate.

Can boiler condensate go into rainwater?

It is possible to terminate a condensate pipe into a rain water down pipe that terminates into the foul waste system. An air break must be installed between the appliance condensate outlet and the drainpipe connection. This needs to be external to the property to avoid flooding should the downpipe become blocked.
