How to Install Insulation on Your Cold Water Tank

We recommend using a cold water tank insulating kit, especially if you have previously fitted a high level of insulation with no success. The insulated panels generally come as two pieces; one long piece to pass around the water tank and another smaller piece which covers the lid. Wear protective gloves, eyewear and a dust mask. Fibreglass insulation can cause respiratory and skin irritation so it is important to try and avoid disturbing the insulation as much as possible. Lay a board down over the insulation so you can kneel down comfortably beside your work area.

Unroll the jacket, shake lightly and allow a few minutes for the insulation to expand. Wrap the jacket around the tank, starting at the centre of one of the short sides. Make sure all sides of the tank are covered.

Loosely tie the jacket using the ties provided in the kit. Make sure the ties are evenly spaced one third from the top and one third from the bottom of the tank.

Place the short panel over the tank lid and using a scissors, cut the insulation to allow entry of vent pipes (if fitted).

Use duct tape to seal the edges all around the insulation.
