Commercial Boiler Repair Leeds – What Causes Heat Exchanger Failure?
Commercial boilers are very different from domestic boilers because they are built to heat and service large buildings. This means that they need the power to heat and circulate huge amounts of hot water around over more extensive pipe networks. When breakdowns occur, it is a big job as commercial boilers are very complex. Enertech FM is an innovative maintenance company and offering responsive and professional commercial boiler repair in Leeds. Using a team of versatile on-call gas engineers, we offer emergency plumbing and boiler repair callouts to cover you in the event of a breakdown. Boiler problems can arise from a number of different things, a common one being heat exchange failure.
What Are Heat Exchangers?
The heat exchanger is probably the most intensely used component of a commercial gas boiler which is why we see so many problems arising from them. They seek to transfer the heat created from the boiler’s fuel source via water which is sent through the cold water heating area via a pipe. As the boiling hot water loop flows through the exchanger, heat is emitted from its surface thus boiling the cold water ready to be pumped to radiators.
Fouling Of The Exchanger Surface
Fouling is a very common issue in commercial boilers especially ones that are significantly old. The term refers to the buildup of deposits like sand, rust or limescale on the exchanger surface over time. Much like kettles, residue buildups will occur on anything metallic if it is constantly exposed to water over time. In areas of hard water fouling is significantly more likely. When the exchanger surface is coated in scale, the component’s ability to transfer heat is severely reduced resulting in underperformance, low heating temperatures and slow responses. If your building’s heating has become slow and less responsive then you need commercial boiler repair Leeds from professionals that can clean and recondition your heat exchanger unit.
Unwanted Air Disrupting The Exchange Process
Sometimes when boilers are set up, there is unwanted air in the water tank which can also affect the transfer process negatively. If there are air pockets surrounding the heat exchanger then less heat is going to be transferred efficiently from the exchanger to the water. Air is about 25 times more inefficient at conducting heat compared to water so having any kind of air barrier between the exchanger and water will result in lost heat. Unwanted air is usually the result of improper start-up venting or faulty interior seals. At Enertech FM we specialise in commercial boiler repair in Leeds and the North West, our gas engineers will be able to properly vent your boiler and make sure that there is no air inhibiting the exchange process.
Heat exchangers usually come in the form of ribbed tubes as this gives a maximum surface area from which heat can be transferred. Cracked tubes on the exchanger can be down to a number of problems like welding defects, rust and general wear and tear that occurs from being exposed to constant heat and pressure. These breaks are dangerous and can result in leakages and the emission of deadly carbon monoxide so it is important you call a central heating professional.
