What is a gas condensing boiler? | Viessmann

In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is

2009/1/10 · If the condense waste water has backed into the boiler or home and frozen serious damage could result, which will involve a very costly repair I do not recommend that you try de-icing the pipe. You might cause more damage and any condensing boiler should only be serviced or mended by a trained and qualified plumber having experience in that type of condensing boiler.

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., which would otherwise have been wasted.

2017/10/31 · If your boiler pressure levels are over 30 psi (pounds per square inch), your pressure relief valve is letting out steam as a safety measure. You see, your pressure relief valve is designed to prevent your boiler from building up too much pressure and will automatically discharge hot water/steam when pressure levels hit a dangerous level of 30 psi (pounds per square inch) or higher.

Is your boiler condensate pipe leaking? Here's what to do!

2019/12/17 · 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.

By expelling the water waste from your system down an external drain, the dangerous fumes that are produced can escape in a safe manner away from the property. At the same time, because of the nature of condensing boilers, you're able to save a lot of money since your boiler is able to recycle any lost heat to continue to heat your home.
