Does a condensing boiler need a drain?
A condensing boiler will produce about 2 litres of condensate an hour at an average temperature of 30-40℃. This condensate needs to drain into your waste water outlet or to a drain via your condensate pipe.
How much water should come out of a boiler condensate pipe?
around 2-3 litres
There will often be around 2-3 litres of condensate water produced in an hour if the boiler is operational. Typically, it is expelled in around 300ml bursts, so you may hear the water going through the pipe at intervals.
Can boiler condensate drain to ground?
Under no circumstances should boiler condensate be put straight to ground or down the side of buildings without first being neutralised. We have seen a reasonable number of installations where the condensate outlet drain is released directly down the side of the house or flat.
What comes out of a boiler condensate pipe?
Condensate is what gets produced when your boiler is being used to heat your home or produce hot water. This is because when your boiler burns fuel, a chemical reaction causes produces carbon dioxide and water vapour by-products. After this water has been collected, it gets expelled out the condensate pipe.
What does a boiler condensate pipe look like?
Look under the boiler to see if there is a plastic pipe – It’s usually white and around 20mm (about ¾”) wide. The pipe should run to the outside of your home and should always run into a drain. The condensate pipe is the diagonal pipe running along the side of the house.
Where does condensate line drain?
In newer homes, HVAC condensate drains are tied most often to bathroom drains. Common drain lines inside your home include in your bathrooms (sinks, shower or tub, toilet), kitchen (sink, water line to your freezer), laundry room, and water heater.
Where is the condensate pipe located?
Look under the boiler to see if there is a plastic pipe – It’s usually white and around 20mm (about ¾”) wide. The pipe should run to the outside of your home and should always run into a drain. An example of a condensate pipe is shown below. The condensate pipe is the diagonal pipe running along the side of the house.
Why is water coming out of my condensate pipe?
The boiler condensate pipe is blocked The condensate has frozen inside the pipe, which leads to a blockage and therefore you get a leakage upstream. You can simply solve this problem by pouring warm water onto the pipe. After that, inspect it carefully, along with the fittings, because they might split if frozen.
Does a condensate pipe need a trap?
Manufacturer’s instructions must be followed for the correct connection of the condensate discharge pipe from the boiler as this may vary due to the design of the boiler. For example a visible air break and trap is not required if there is a trap with a minimum condensate seal of 75 mm incorporated into the boiler.
Where is the condensate pipe on my boiler?
Where is the condensate pipe? The condensate pipe runs from the boiler to a suitable existing waste pipe system, or external drain pipe. If it is connected to an external drain pipe, it will be found outside your property leading out from your boiler.
Where is my condensate pipe?
You’ll usually find your condensate pipe leaving your home at the nearest outside wall. It usually looks like a small, white pipe starting from the wall, then heading down into a drain or run off system. Condensate pipes can sometimes be connected straight into waste water flows, such as the waste pipe of a sink.
Where is the condensing pipe on a boiler?
What size pipe for condensate drain from a combi boiler?
Hi, I’ve been told by a gas safe engineer that the condensate drain from a combi boiler must only use pipe that has been joined with solvent weld. (I used 22mm barrier pipe and speed-fit elbow, joining into a 40mm waste pipe that has plastic compression fittings).
What does the condensate pipe do on a boiler?
The main job of the condensate pipe is to transfer the wastewater that gets produced from the boiler, into the sewer. As simple as this may appear to be however, it’s important to know whythis happens.
Can I connect the boiler condensate discharge pipe to an internal pump?
Where it is not possible to connect the boiler condensate discharge pipe to an internal “gravity discharge point” then the installer should use a condensate pump connected to a suitable internal connection point such as an internal soil stack (preferred method), internal kitchen or bathroom waste pipe such as a sink, basin, bath or shower waste.
What is the best material to drain condensate from a boiler?
Condensate from condensing boilers is quite corrosive, a view shared by experts (Xinqiao 2006). That’s why plastic is a good drain material. Stainless steel might be acceptable in some situations.
