  • Installer Guide to Condensate Discharge Pipe Installation 2019

    Installer Guide to Condensate Discharge Pipe Installation. Correctly fitted condensate discharge pipes are vital to the function of a condensing gas or oil boiler. Due to a high volume of boiler breakdowns caused by the freezing of condensates, a guide has been published for installers by the HHIC.Learn More

  • Condensing boiler - Wikipedia

    Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.Learn More

  • Is a high efficiency, condensing gas boiler the best

    Aug 13, 2018 · The condensate drains to the bottom of the heat exchanger and runs out of the boiler through a condensate drain. Because this fluid is a byproduct of combustion, it is acidic, typically between 3.2 and 4.0 pH (which is significantly less caustic than lemon juice or soda).Learn More

  • Will Furnace Condensate Corrode Plumbing? | Building Advisor

    Jan 01, 2019 · High-efficiency boilers and furnaces require a condensate neutraliser to protect drain pipes from corrosion. ©123RF.COM. Condensate from a high-efficiency furnace typically has a pH of about 5.0, but can range from 3.5 to 6.5. It's important to note that pH is a logarithmic scale, so pH 5 water is 10 times more acidic than pH6.Learn More

  • Confused about acidic condensate — MoneySavingExpert Forum

    Nov 12, 2008 · I'm currently getting quotes for a new central heating system. I was told by one engineer that the condensate from a gas condensing boiler is acidic and if sent down an old cast iron waste stack, it will corrode it. To get around this, it would either need it's own plastic piping or pump it up into the plastic guttering.Learn More

  • Condensate pipe poking out of wall (not connected to drain

    Jun 04, 2020 · 71,294. Thanks Received: 4,043. Location: Crossgates. Country: ayebut said: ↑. Hi, I had a boiler installed in my first floor flat and the engineer has left the condensate pipe sticking out of the wall by a few inches - it doesn't connect anywhere. He says it can just drip into the earth below.Learn More

  • Condensate Neutralizer Kits - AERCO

    AERCO Condensate Neutralizers are ideal for neutralizing condensate from condensing boilers, water heaters and furnaces operating on natural gas or propane. Condensate is acidic and has the potential to harm the environment and the sewer system. The AERCO Condensate Neutralizer will raise the pH of the condensate to a more neutral level before Learn More

  • Condensing boiler - how much condensate

    Jan 07, 2010 · Re: Condensing boiler - how much condensate. I insisted that our condensate pipe was run internally, into the soil stack. I reckon half a bucket an hour at full tilt, but that's a guess based on when our condensate trap, or more accurately its drain plug, sprung a leak a couple of years ago.Learn More

  • Installer Guide: Condensate discharge pipe installation

    installing boiler condensate discharge pipes Figure 3 – Connection of a condensate pump - typical method (NB manufacturer's detailed instructions should be followed). Note – Any external pipe work should be insulated, pipe cut at 45 degrees and a drain/ leaf guard fitted. Key 1 Condensate discharge from boiler 2 Condensate pumpLearn More

  • Clogged Condensate Drain Lines In Boilers - Howell Mechanical

    Condensate drain lines have traps – they're often U-shaped, though they can be siphon-based traps. These are the parts of the drain line that are most likely to get clogged. When the drain lines become clogged, the condensate can begin to flow back into the bottom of the heat exchanger. When this happens, your boiler will turn off Learn More

  • How to Clean a Boiler Condensate Trap | Viessmann

    For example, compared to an old G-rated non-condensing gas boiler, an A-rated condensing model can save a detached home over £300 a year in energy costs. To experience the ongoing benefits of a gas condensing boiler, you'll need to make sure it stays in good condition - and among other things, this means keeping the boiler condensate trap clean.Learn More

  • Managing Condensate for Condensing Boilers

    All Hamilton condensing products contain a condensate drain assembly that provides for the following: Connection to the main drain port on the heat exchanger. Connection to the inlet air condensate removal system. Connection port for the sensing line to the pressure switch monitoring the condensate flow and excess pressure on the venting system.Learn More

  • Boiler condensate drain pipe | Screwfix Community Forum

    The pipe work from the boiler should be of a minimum 19mm ID or as per manufacturer's instructions and the condensate discharge pipe shall be run in a standard drainpipe material, e.g. poly (vinyl chloride) (PVC), un-plasticized poly (vinyl chloride) (PVC-U), acrylonitrile butadiene-styrene (ABS), polypropylene (PP) or chlorinated poly (vinyl chloride) (PVC-C).Learn More

  • Condensate trap - DIY Plumbing

    Nov 02, 2018 · The condensate trap is a device inside a condensing boiler which collects water from the condensing process before it is expelled into the sewer via the condensate pipe.The purpose of the trap is to prevent toxic gases from entering the condensate pipe, and to manage the flow of condensate fluid out of the boiler.Learn More

  • How to fix and prevent a frozen boiler condensate pipe

    Feb 08, 2021 · The main reason that a condensate pipe freezes up is because the boiler and pipework have been poorly fitted. There are a couple of options. First, see …Learn More

  • Boiler Condensate Drain | DIYnot Forums

    Sep 03, 2019 · The neighbours upstairs have a Condensing boiler, the condensate drain has frozen, nothing unusual there then?? BUT?? the The boiler is sited in an Un-Heated room, the drain is completely internal, no pipework exposed to the somewhat stiff breeze at -4C at present. Worth considering how to avoid the above? especially in say a Garage?? Ken.Learn More

  • Boiler Condensate into Septic Tank — Heating Help: The Wall

    Feb 03, 2009 · The condensate I wish to allow to drain via ABS to the septic DOES INDEED get neutralized. The local inspector is not allowing any condensate to enter the system. He prefers to to send it through the wall and make a muddy mess in the sideyard. Also, and I don't want to make anyone feel bad, it doesn't freeze here. I use 38 degrees as a design dayLearn More

  • Condensate Neutralizers for Condensing Boilers/Heater

    Clogged Condensate Drain Lines In Boilers. Back in the day, boilers were terribly inefficient; there were hot gases that would escape from the boiler. Heating engineers thought to themselves "Hey, we can use that heat for something", and condensing boilers were born. One byproduct of condensing boilers is the condensate drain line – which, unfortunately, can get clogged.Learn More

    Oct 15, 2019 · With both floor drains and condensate pumps, problems occur when the liquid cannot drain properly from the boiler. Under sizing the condensate line from the boiler to the drain can be one reason that this occurs. When sizing these lines, some contractors underestimate the amount of condensate liquid that comes from a condensing boiler.Learn More
