Frozen condensate pipes can affect any boiler in an area with harsh winters and exquisite temperatures. Failing to address this issue will ruin your boiler, so you will most likely spend a fortune to repair it. Fortunately, a quick check every once in a while can prevent these issues. Moreover, thawing is the most common solution to this problem. However, no matter how simple it seems, the truth is that you need a qualified plumber for it. Otherwise, you risk damaging the respective pipe, which will inevitably lead to plenty of other issues. Plumbing is not the best field for DIY projects.
