Without a good level of insulation, a water tank will struggle to retain heat. This means it will lose heat extremely quickly and therefore more energy is needed to continually reheat it, time and time again. Not only does this impact heating the building, but also the use of hot water. As hot water is needed and used throughout the year, water tank insulation is beneficial at all times. It’s not something that you will notice during the winter months alone when you need to heat the building, properly insulating a water tank can even save you money during the warmer months as hot water is always being used regardless of the temperature outside. When you consider water tank insulation in this way, it’s very easy to see how it can save money and energy. An insulated water tank uses less energy and therefore you will spend less money on energy bills. Insulation is also very important for cold water tanks, as water temperatures dropping too low can cause pipes to freeze and damage. This means that insulation can actually help you to avoid repair costs going forward, as damaged pipes need replacing and the cost of this can quickly add up.
