How Insulated Cold Water Tanks Function

Insulated cold water tanks create a thermal barrier between the water inside the tank and the surrounding environment. This insulation ensures that the water remains at an optimal temperature, making these tanks ideal for areas with fluctuating temperatures.

Considerations When Selecting an Insulated Cold Water Tank

• Tank capacity
• Insulation material and thickness
• Planned usage of the tank
• Manufacturer’s reputation

Tricel offers a range of Regulation 4(1)a certified One Piece Tanks and Totally Internally Flanged (TIF) Tanks with a standard 25mm insulation, upgradable to 50mm. Our Hot-Press Sectional Tanks come with 38mm standard insulation, also upgradable to 50mm. Additionally, we provide non-insulated tanks suitable for non-potable water storage.

Uses of Insulated Cold Water Tanks

• Agriculture
• Healthcare
• Food Processing
• Domestic purposes
• Commercial & Industrial sectors

Advantages of Insulated Cold Water Tanks

Energy Efficiency
Insulated cold water tanks require less energy to maintain water temperatures, reducing energy costs. This efficiency avoids the need to constantly cool or heat the water, saving both energy and money.
Heat Loss Prevention
Insulated cold water tanks minimise heat loss, especially crucial in cold climates. Insulating tanks in regions like the UK reduces the risk of water freezing, which can cause tank damage.
Condensation Reduction
The insulation also prevents condensation on the tank’s exterior, safeguarding it from moisture-related damage. Inside the tank, insulation helps prevent mould growth, ensuring water purity.
Prolonging Tank Lifespan
Consistent temperatures and reduced stress on the tank extend its lifespan, offering long-term savings.

Supplying the Biggest Projects

With vast experience, we have completed various projects across different industries. No project is too big or complicated for us at Tricel. Every project is different, and we have installed GRP water tanks where space was restricted to a minimum and other structural factors were a concern.

Preventing Freezing in Cold Water Tanks

Temperature Monitoring

To comply with Regulation 4(1)a and prevent Legionella growth, cold water tanks should maintain temperatures below 20°C. The Legionella bacteria thrives in water between temperatures of 20-45°C. Keeping the water temperature lower than this and above 60°C eliminates the threat of the bacteria. Installing temperature sensors allows for precise temperature control, activating heating systems when temperatures drop. Advanced systems can offer remote monitoring and alerts.

The sensors will trigger the heating system to activate when the temperature drops below a set temperature. Advanced systems may even provide remote monitoring and alerts, allowing facility managers to respond to temperature fluctuations promptly.

Frost Protection

Constant water movement reduces freezing risks. Frost protection compensates for heat loss. M&E Consultants can decide whether frost protection is necessary for your specified water storage tank. In that case, we can provide 50mm insulation instead of the standard 38mm insulation.

One effective method is to insulate the tanks, which helps retain heat and to avoid freezing. In freezing climates, it may be necessary to use heat tracing or immersion heating in combination with insulation for comprehensive frost protection

Heat Tracing & Immersion Heating

While trace heating and immersion heating are beneficial, they alone won’t prevent freezing. Proper positioning of these elements is crucial. Ensuring uniform heat distribution prevents localised warming and potential freezing.

Trace heating is a method that provides a consistent source of warmth and is typically used for large water tanks or those located in unheated plant rooms.
