As such, when looking to resolve these issues, the best course of action is to start with having a water quality test carried out. Testing can range from a basic sampling and laboratory analysis with initial feedback, to a full interrogation and in-depth 30-section report with specific recommendations. Water quality tests, such as those offered by Spirotech, benchmark against the recommended levels of pH, conductivity, water hardness, and if there is any protector present. The results from these will help in putting a plan together to tackle the two main issues of corrosion and scaling. Depending on the results of the water test, recommendations could range frommany mechanical solutions, such as the fitting or replacement of a pressurisation unit, vacuum degasser (for the elimination of microbubbles and dissolved gases), or a dirt separator. Another new technology currently growing in popularity here in the UK are demineralisation solutions. Demineralisation solutions treat the water to ensure it is pH stabilised before it enters the system. By removing all the hardness (calcium and magnesium) from the water, to prevent the boiler from scaling and eliminate calcium deposits, and remove all salts (ions) from the water to help slow down corrosion, this can have great improvements in the performance of the heating or cooling system. Water quality tests can be done at any time but should be part of a regular service agreement to guarantee long-term results. If the site does not have an agreement in place, the chances are thewater will not have ever been tested in the past. Another good reason for carrying out a water quality test is that many HVAC manufacturers will only offer a warranty if the system water meets certain standards. With causes both identified and remedied, heating systems will harness the potential to work optimally, thus consuming less energy for the same desired outcome and in turn, having a positive effect on the associated costs with energy heating bills. At a time when it is important to consume energy more efficiently from both a financial and environmental point of view, testing and upgrading commercial water systems can help reap the benefits of each perspective. Professional Development In order to really get the best from any heating or cooling system and benefit from improved efficiency, it is important that facility managers are taking the time to educate themselves on the best practices when it comes to water treatment. We offer heating and plumbing professionals technical insight into the benefits and importance of these changes to a water system, through its UnderstandingWater Quality and Total Solutions CPD. The course identifies common problems caused by poor water quality, and outlines 8 key steps that can be taken to remedy these issues. Other topics covered include hydronic stability, the latest regulations and guidelines, how water conductivity causes corrosion, along with other factors such as the impact of hard and soft water. Bacterial contamination in closed heating and chilled water systems is also examined and explained.
