Can boiler condensate go into a soakaway?
If the condensate discharges outside and no drain is available, a purpose made soakaway can be fitted. This must be fitted to the manufacturer’s specifications. In other words, the correct distance from the property, and the correct depth down, so dampness does not come into the house.
Where do you drain the condensate on a boiler?
In the condensate process, wastewater is produced. This needs to exit the boiler and does so through a small pipe called the ‘condensate pipe’. This will usually exit out behind the boiler, through the external wall, and connect to a drain. It will be made of plastic.
How far should a condensate soakaway be from the house?
Should be 500mm from foundations and depending which make you use should have the holes facing away from building.
Does boiler condensate need a trap?
The boiler should never be operated without the condensate trap in place, as it prevents noxious combustion gases from travelling down the condensate pipe.
How does a condensing boiler heat water?
Condensing boilers are water heaters fueled by gas or oil. They attain high efficiency by using waste heat in flue gases to preheat cold water entering the boiler. Water steam that is produced during combustion is condensed into liquid form, which leaves the system through a drain.
How much water should come out of a condensing boiler?
An efficient condensing boiler will generate around 2 litres of condensate water an hour at a temperature of around 30-40°c. This needs to be safely disposed of, within the buildings waste water system.
How much water does a condensing boiler produce?
What size should condensate pipe be?
Any external boiler condensate pipe must be a minimum internal diameter (ID) of 30mm, and insulated, using suitable waterproof and weatherproof insulation. Any internal condensate pipe should be a minimum of 19mm ID and upsized to 30mm ID minimum before passing through the building structure to outside.
How do I know if my boiler is condensing?
If you can see the steam coming from the flue through an external wall (or roof), and if you also have a white plastic pipe leading to a drain, this will certainly be from a condensing boiler.
Does a condensing boiler need a flue?
Why Would I Need to Move My Boiler Flue? The regulations and guidelines for boiler flue siting have changed significantly since condensing boilers were made compulsory in 2005. If the flue goes through the roof (a vertical flue) rather than a wall (horizontal flue) then other alterations may need to be made.
Does a condensing boiler need a water supply?
Condensing boilers help the environment with an increased efficiency to up to 12% . Space savings: a condensing combi boiler does not need a hot water tank and is available in a wide range of compact sizes, making it much suitable and convenient to fit in a kitchen cupboard than conventional boiler models.
Where does the condensing go in a soakaway?
One additional domestic appliance of soakaways is the condensate soakaway. Condensing boilers located near an external wall within a property are designed to collect condensing steam created when a boiler heats up. The, now cooler, condensed water then runs off to a soakaway pipe.
Why do you need a soakaway for a boiler?
This means that the boiler has less work to do to heat the water. The condensing water is collected in the main body of the boiler and this needs to fall by gravity to a drain . (A)pump it to a drain. (B) Fit a soakaway (when there is an outside wall available).
How is a soakaway used in the UK?
Soakaways are used to manage surface water at its source, and serve as an alternative option to draining off surface water via a stream or sewer system.
How does a condensate pump in a boiler work?
Condensate pump or soakaway? Condensing boilers do this by having an extra heat exchanger in the flue. As the flue gases (fumes, smoke… and the like) heat up the water (or some cases the air) some of the steam condenses and is collected in the boiler. This means that the boiler has less work to do to heat the water.
