What kind of tubing should I use for draining condensate

The boiler now needs to be able to manage this condensate by draining it from the bottom of the heat exchanger and out to the drain in the boiler room. Since the condensate is acidic, it will corrode floor drains and concrete unless it is treated before being sent to drain. In some cases, neutralization treatment is required by code.

Feb 19, 2017 · If using a neutralizer before a condensate pump I stick a scrap of 3/8" OD copper in the discharge tube for the same reasons. My first home boiler was a high 80% near condensing cast iron WM Gold GV model. The plastic drain hose was about 6" short of the PVC floor drain. The first years of use eroded/etched the concrete floor, cutting a groove

Condensate drain problems - Central Heating and Gas Boiler

The condensate trap is absolutely mandatory for a high-efficiency gas furnace. Since the drain taps into the exhaust system, leaving it open to the air would allow for a potential exhaust/flue gas leak in the living space, which is a big no-no. Additionally, the inducer motor would suck air through the drain if it weren't trapped, which could

Dec 16, 2018 · My boiler has an outlet fitting for this condensate water but the manual doesn't say what kind of of tubing should be used to drain it. The other tubing attached to my boiler is copper (for the water in/out) and steel or iron for the gas connection. The fitting for the condensate is plastic, however, which I'm sure is for a good reason.

Dec 17, 2019 · The condensate pipe is used to drain all the excess water produced from the condensing process in your boiler. Since the water, aka the condensate, is mildly acidic (that's because it is a by-product of the condensed waste gasses), it needs to be drained through a PVC or ABS pipe. Any metal pipe used would corrode.

Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less. It is this resulting condensate liquid that is acidic and requires treatment to avoid damage to piping systems, sewerage systems and other items it may come in contact with.
