How to Keep Your Water Systems Safe in Cold Weather

18 December 2024

As the temperatures plummet across Scotland, keeping your commercial buildings warm and comfortable becomes a priority. However, amidst the focus on heating systems, it's easy to overlook the potential dangers posed by the cold to your water systems. Here at Caledonian Heating & Plumbing Ltd, we understand the importance of year-round water system maintenance. In this blog post, we'll share some key tips to help you keep your water systems safe and prevent costly issues during the cold weather months.



The Risks of Cold Weather for Water Systems


When temperatures drop below freezing, water pipes are at a higher risk of bursting. This can cause significant damage to your property, disrupt operations, and lead to costly repairs. Additionally, cold weather can create ideal conditions for the growth of Legionella bacteria, a potentially life-threatening pathogen that thrives in stagnant or slow-moving warm water.


Here are some specific concerns to be aware of:


Pipe Bursts: When water freezes, it expands, putting immense pressure on pipes. This pressure can cause pipes to crack or burst, leading to significant water damage.

Legionella Growth: Legionella bacteria can multiply in water systems that are not properly maintained, particularly in areas with lukewarm water temperatures (between 20°C and 45°C). Inhaling aerosolised droplets containing Legionella can lead to Legionnaires' disease, a serious form of pneumonia.


Taking Action to Protect Your Water Systems

Here are some essential steps you can take to mitigate the risks posed by cold weather to your commercial water systems:


Insulate Exposed Pipes: Insulating exposed pipes in unheated areas, crawlspaces, and attics can help prevent them from freezing. 

Maintain a Consistent Minimum Temperature: If your building is unoccupied for extended periods during winter, consider setting the thermostat to a low but consistent temperature to prevent pipes from freezing.

Drip Faucets: In particularly cold weather, dripping faucets can help prevent water from freezing inside the pipes.

Schedule Regular Water System Maintenance: Regular maintenance by a qualified professional like Caledonian Heating & Plumbing can identify potential problems before they occur. This includes checking for leaks, ensuring proper insulation, and flushing your system to prevent stagnation.

Conduct Water Risk Assessments and Legionella Testing: A water risk assessment will identify areas within your water system where Legionella growth is a risk. We can also conduct regular Legionella testing to ensure your water system is safe.
