Hydronic Heating systems are exceptionally reliable and tend to run for years without any technical trouble or need for a repair. However, like any automatic power system, it’s inevitable that components and parts of the system will breakdown at some point in its lifespan. But when this does occur, it does not mean that you’ll have to replace your heating system entirely. In most cases your hydronic system will simply need a repair or service through which your system not only increases its efficient functioning but will also increase its lifespan and reliability in the following years.
There are many different technicalities that may fault when your hydronic system begins to shut down. Here is a list of a few common problems that may occur and the service required to fix it.
Power flushing is a cleaning process which removes accumulated deposits of sludge from a hydronic heating system. Over years of use, sludge tends to build up within your hydronic heating system whether its in your radiator panel, floor heating or your boiler. Sludge is a mud like substance that sticks to parts of your heater which causes the slow decrease in efficiency of your system. In some cases, it can even cause blockages, corrosion and eventual damage to your boiler.
Professional servicing teams are able to flush this sludge out of your heating system to help return the boiler to its optimal performance condition. It is recommended that each hydronic system be power flushed every 5-10 years in order to ensure the continuous reliable functioning of your hydronic heating system.
Air in radiators
Radiator systems can often become cold at the top which indicates that there is either air or hydrogen within the system. As a result of electrolytic corrosion, hydrogen gas often builds up and can eventually lead to the inefficient functioning of your heater. It is important to recognise if your heater has stopped heating at its full capacity, because if left untreated, radiators can develop an accumulation of sludge that will restrict the flow of hot air and ultimately reduce heat transmission.
Pump failure and seizure
Continuously untreated and un-serviced systems can develop an enhanced amount of pressure placed on the pump system. This means that the abrasive and magnetic properties of the sludge (often containing black oxide) causes increased bearing and shaft wear to the pumps, which can potentially cause them to fail completely. Therefore it is important to have regular services where a heating professional can observe the condition of the pumps.
When sludge and waste deposits of a large scale and build up in unprotected and overused boilers, these substances can cause an increased pressure and reliance on specific parts of the heater. What this tends to result in is the increased noise of function released from your hydronic system. This can be awfully uncomfortable throughout cold nights and so it is important to request regular power flush services to omit these waste products.
Heating System Cleansing
Before installing your new hydronic boiler, it is important to regularly cleanse and rinse out your heating system prior. It is a good idea to get professional help with this as the cleansing process requires the use of chemicals to fully protect and clean out your system properly. The process of cleansing and rinsing is to remove any debris and residues that have accumulated in the system over time. Through the use of these specific chemicals, your system will be fully cleansed and free of any waste deposits giving it the all clear to install your hydronic boiler.
It is very important that you undergo regular services and repairs to your hydronic heating system. Sourcing a heating professional to undergo all these services will significantly increase both the efficiency and reliability of your system. Ignoring regular services can mean that your boilers won’t last as long as intended and they will not provide the quality of heating that they are designed to offer.
