As a result, the [ ] While the condensate pipe safely transports the wastewater, the condensing boiler efficiently generates this condensate. [M] Condensate disposal A condensing boiler won’t work without a boiler condensate pipe. Condensate traps Building regulations require a trap in the pipe whether it is terminated directly to the outside or before it connects to The condensate pipe should have a fall of at least o ormm per metre away from the boiler where possible. Modern gas boilers can recycle latent heat from waste exhaust gases The guide features several key instructions for installing a condensate pipe that will provide maximum protection to the boiler and the customer. Installation and regulation compliance is key to a functioning Contents1 Boiler condensate pipe regulations for installers Condensate pumps External conditions Unheated areas in buildingBoiler condensate pipe regulations for homeowners Over the years, the weather patterns in the United Kingdom have become more extreme because of climate change. The condensate pipe then disposes of the resultant wastewater, ensuring the smooth operation of the boiler These documents give guidance on how to install the condensate drainage pipes in order to reduce the possibility of freezing The condensate pipe is an integral part of a boiler that channels waste condensate from the boiler to your home’s external drains. Condensate is water produced from the process of condensation. We now have to deal with cold and prolonged sub-zero temperatures. With today’s rising energy a condensing boiler, the heat exchanger has to be made of robust materials to prevent the acidic condensate from corroding and completely degrading the materi-als within the Power Boilers Section I – Power Boilers Provides requirements for all methods of construction of power, electric, and miniature boilers; high temperature water boilers, Selection of condensate discharge pointCombined discharge from pressure relief valve and boiler condensate drainUse of condensate pump British Standards, Building Regulations and boiler manufacturers’ installation instructions currently allow condensate drainage pipes to be located either internally or externally, installing boiler condensate discharge pipes KeyBoilerVisible air break at plug hole – alternative connection can be below sink trapmm sink, basin, bath or shower waste All condensate pipework must ‘fall’ from the boiler by a minimum ofdegrees (52mm per metre)The pipework must allow air to be supplied back to the appliance for temperature (EWT) and a ˚F (55˚C) temperature rise (delta-T) to produce a boiler leaving water temperature (LWT) of ˚F (82˚C). Condensate contains a relatively large percentage (16% in some cases depending on pressure) of the energy that is used to produce the steam. Regular maintenance of your condensate pipe is essential to prevent blockages, particularly during colder seasons when the risk of freezing is high. Every time a condensing boiler works, it produces a condensate. The pipe is responsible for discharging wastewater from the boiler into the sewer. This material is most often stainless steel, although various materi-als are used depending on the boiler manufacturer Condensate piping shall be of approved corrosion-resistant material and shall not be smaller than the drain connection on the appliance. It also outlines the alternative of condensate pumps and how to overcome the challenges associated with existing installations Selection of condensate discharge pointCombined discharge from pressure relief valve and boiler condensate drainUse of condensate pumpChoice of discharge pipePositioning and termination of the condensate drainage pipeIn-line condensate neutralizer devicesMaterials and components British Standards, Building Regulations and boiler manufacturers’ installation instructions currently allow condensate drainage pipes to be located either internally or externally, or a combination of these. The boiler extracts heat from waste gases, improving its efficiency and, as a bonus, reducing energy bills. Such piping shall maintain a minimum horizontal slope in the direction of discharge of not less than 1/8 unit vertical inunits horizontal (1-percent slope). Condensing boiler performance is Condensate Drain Pipe Installation. The number of degree bends should be kept to a minimum, installing boiler condensate discharge pipes KeyBoilerVisible air break at plug hole – alternative connection can be below sink trapmm sink, basin, bath or shower waste trapSink, basin, bath or shower with integral overflowOpen end of condensate discharge pipe direct into gullymm min below grating but a condensing boiler, the heat exchanger has to be made of robust materials to prevent the acidic condensate from corroding and completely degrading the materi-als within the boiler and the ue stack.
