Contractors who install gas-fired condensing boilers know that dealing with the products of combustion is a big challenge when installing these appliances. The difficulty of disposing of the condensate (water) has to some degree been overcome by allowing it to collect in the base of the boiler where it can be disposed of into the drainage system. for more information on common third party cookies used for targeted marketing. Even though the very first models were using somewhat less reliable components compared to conventional heating systems at the time, the latest upgrades that were carried out throughout the last 10 years or so, have significantly improved the quality as well as the reliability of the condensing boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. Low boiler pressure is one of the most common boiler problems and it can have many possible causes. Join our social media community to get updates, You can change your preferred cookie settings below. The primary cause of waterside problems with condensing (and any other kind of) boiler is de bris remaining in the system after installation. Flue condensation is normal for a condensing boiler. They usually have a maximum flue gas temperature of 100 degrees C and are usually much lower; often between 50 and 70 degrees C. Please choose the time you wish to be contacted.

Condensing boilers are not harder to maintain than conventional boiler systems that run on gas or electricity. Read more about our cookie policy. "Condensing boilers are hard to maintain.". With condensing boilers, the flue is effectively part of the heating system, as it is the heat from the burned gases that starts warming the returning water from the system. Although a marginal benefit of about 3% (in terms of heating capacity) can be achieved by coupling a condensing boiler with oversized radiators, it proves impractical and not that cost-efficient as one might expect. That is, turn up the boiler so that we get the fuel-economy of a condensing boiler, and turn down the radiator thermostats. Friday: 8:00am - 3:00pm.

The most common boiler on the market is known as a condensing boiler and one of the main problems with them can be caused by the condensed liquid as it’s removed by a pipe. Everything you need to know about boiler flues A boiler flue, despite its identical pronunciation and similar spelling, has nothing to do with excessive sweating, runny noses, chills and feeling rough. The only difference comes down to ensuring that the condensate drain is clear while used. Thus, one shall not worry about the appropriateness of operating a condensing boiler with standard size radiators, all the more so when most of the current heating systems have already integrated large radiators. Since the flue gases leaving the condensing boiler are cool, they tend to produce a noticeable mist of water vapour around the flue terminal (outlet) itself (as the gases condense upon contact with the surrounding air masses). Become an affiliate, Opening Hours in the face if you go outside into my back-yard, not to mention that hanging any washing out (obv. The boiler’s flue grommet can deteriorate and dislodge during use and allow … Viessmann Vitodens 100-w 30kW is very popular, but it is also available as 26kW and 35kW.

With modern condensing boiler systems, only about one litre per hour of condensate is produced, which has the pH levels of between 3.5 and 5. Nevertheless, one should give much attention to the boiler and flue location prior to installation, as to make sure that the forming plume won’t get close to the neighbouring properties or pedestrian paths. "Condensing boilers are difficult to install.". It does so by using the previously untapped heat that comes from exhaust gases, that in the case of a conventional boiler system, would normally be released into the atmosphere. When in condensing mode the flue gases give up their ‘latent heat’ which is recovered by the heat exchanger within the boiler and used to preheat the return water. The risk: The boiler’s flue grommet can deteriorate and dislodge during use, allowing the boiler to emit carbon monoxide, posing a risk of CO poisoning, according to the CPSC’s recall notice.
