What is Water Tank Insulation?
The insulation itself is a material applied to cold water tanks to eliminate the risks of tanks cracking due to harsh cold conditions and to prevent heat loss. The insulation prevents the water from being affected by external elements, including ever-changing temperatures, making water storage a long-term, cost-effective solution. There are several ways the insulation can be applied, including:
- Blanketing: involves applying insulation in blankets or as an insulation jacket, mainly for water storage tanks in an attic.
- Foam: this type of insulation is sprayed directly onto the surface that needs to be insulated, forming part of a protective layer for the water tank.
The Benefits of Having an Insulated Water Tank
An insulated water tank ensures a safe and consistent year-round water supply that can be used for various reasons, from consumption to cleaning. There are many benefits to having an insulated water tank, including the following:
Preventing Heat Loss
One of the main benefits of water tank insulation is that it prevents heat from escaping. This is vital as it prevents the tank owner from incurring unnecessary costs on their energy bills heating the water back to the desired temperature. Insulation is essential in colder regions as it prevents the water tank from freezing or cracking.
Besides the potential risk of the water storage tank freezing during cold seasons, the safety of the water supply in tanks that are located outdoors can be affected in cold climates. However, applying thermal insulation protects the water tank and does not require energy or maintenance after installation.
REDUCE ENERGY LOSS
When an uninsulated water tank cannot keep its contents at the right temperature, energy is used to either cool or heat the water to the desired temperature intended for its use. This repeated energy use will result in higher costs being incurred. Additionally, the water tank will waste energy if the temperature is unstable. An insulated water tank is energy-efficient as it does not require additional power or features to control and regulate the water temperature. The water storage tank will maintain its ideal temperature with greater efficiency.
Generally, uninsulated water storage tanks create a large amount of moisture and condensation. This can cause problems as the condensation leads to mold potentially growing within the tank and contaminating the water supply. An insulated water tank can reduce or eliminate these risks.
How Thick Should The Insulation Be?
The thickness of an insulated water tank largely depends on the severity of the climate and how much temperatures fluctuate during the year. In colder climates, the insulation has to be stronger, allowing for greater protection from the outside temperatures and preventing the water storage tank from freezing. The 2021 International Energy Conservation Code states that all pipes in hot or cold water storage tanks with operating temperatures of 105°F or more, or 60°F or less require insulation.
Enough insulation must be used to be effective. Generally, the thicker the insulation, the more effective it is at preventing heat loss. According to DIY Data, 50mm thick insulation should be used, and this is also the frequently preferred thickness within the market.
Eco-friendly Insulation Material
As the issues around global warming and ozone depletion become more prominent, manufacturers, suppliers and customers of insulation materials and products are looking for eco-friendly alternatives. CFC-based insulation foam contributes to the problems faced by the environment. Tricel manufactures insulated water tanks known as the format 30 which means the tank roof and all sidewall panels are insulated with CFC-Free polyurethane foam. This insulation meets the water byelaws.
Different types of insulation material that can be used are safe and eco-friendly, including spray foam made from soybeans does not have any harmful chemicals, or fiberglass insulation made from recycled glass bottles. Having an insulated water tank reduces the need for electricity or other fuels to heat or cool the water supply, positively impacting the environment by reducing CO2 emissions. The thicker the insulation, the lower the CO2 emissions.
