- Proprietary jackets will fit most cold water tanks. Start by flopping the jacket over the tank arid pulling it roughly into position.
Rather than cut into the jacket’s ‘envelopes’, try to accommodate a pipe by parting the seam between them. All cuts must be sealed with tape.
When installing blanket insulation start with the side of the tank. If you’re using glass fibre blanket wear gloves and a face mask.
- If the blanket isn’t as wide as the tank is deep, a second layer, which should overlap the first, will be necessary. Use string to hold the blanket in place.
- The tank must have a firm lid to prevent the water inside being polluted. Don’t tie the lagging to the lid in such a way that it is impossible to undo.
- Expansion tanks riced insulating too. If using sheet polystyrene, remember to cut the panels so that their ends overlap when fitted to the tank.
- Use tape, string, or glue to hold the side panels together. Fill the gaps left as a result of making cut-outs with wedges of waste polystyrene.
- Make a lid for your tank by gluing together two panels of polystyrene. The smaller (inner) panel should just It inside the tank. Hot Tanks
- When using a proprietary jacket to insulate a hot water cylinder, start by securing the polythene ‘envelopes’ round the hot water supply pipe.
- The sides of the jacket are held in place with straps. Take care not to cover the capping and wiring of any immersion heater.
