Planning for installation . . .
- Determine the size of your geyser and make sure the geyserduvet pack will be suitable.
- For installations in ceilings, take every precaution not to stand on ceiling boards. Only stand on joists / beams.
- Use planks (minimum 32mm thick and 900mm long) as temporary floorboards to stand on by placing them over adjacent beams / joists.
Suitable ladder, heavy duty or kitchen scissors, a carrier bag for tools, a head torch, a tape dispenser (50mm wide), screwdriver for thermostat and inspection plate, a damp cloth and a dry cloth.
- While one person can install the geyserduvet with ease, it will be quicker when assisted.
- Wear old clothes (dusty ceiling) and good footwear for standing on the joists and beams. You will get hot, dress accordingly.
2 Setting the thermostat temperature
- Switch off electrical power supply to the geyser for the duration of installation.
- Open the thermostat inspection cover and check what temperature the thermostat is set to. To optimise savings, we recommend setting it to 50-55 degrees Celsius or lower if desired. Once set, screw the cover back in place.
- Insulating more or all exposed hot water pipes will reduce the temperature setting you will need for hot water at your tap.
3 Keep it cosy
When installing the geyserduvet, do it so that none of the duvet is squashed flat against the pipes or cylinder if possible. Flattening the insulation will reduce the available thermal resistance.
4 Install pipeduvets
- If necessary, run hot water to determine the hot water pipe.
- Install two pipeduvets on the hot water pipe nearest the cylinder.
- Start against the cylinder and work away, completely sealing/engulfing the hot water pipe, including all bends and joints.
- Have about a 5cm overlap on pipeduvets.
- Install the third pipeduvet on the cold inlet pipe nearest the cylinder.
- Do not cover any of the valves – this could lead to the failure of your geyser.
- Additional pipeduvet insulation is recommended on the hot water pipes between the geyser and the taps. They can be purchased separately.
5 Installing the geyserduvet panels
- Wipe the geyser cylinder clean and free of dust with a damp cloth. Wipe dry with a dry cloth.
- Before cutting panels or committing them with the double-sided tape, measure up and plan to cover all or most of the geyser;
- Hold panels in place to be sure of optimal cover
- The top long panel should overlap the side long panels.
- Install the long panels first and from underside to the top – joining panels underneath if possible.
- Install the short, end-panels last
- Cut the panels where needed to fit around geyser legs and adjoining pipes. For a snug fit, use fastening tape to reseal duvet dust covers where they were cut.
- When you are ready to commit the panels to their positions, remove tape liner on the strips of double-sided tape press panels in place against the geyser.
- Seal all panel edges and joins with fastening tape against geyser or adjacent, overlapping panels.
- Finally, make vertical and horizontal straps with excess fastening tape, making sure not to flatten the insulation.
6 Remove all tools
Recycle the plastic carrier bag as a bin bag and dispose of adhesive tape liner.
7 Switch the power supply for the geyser back on.
