Service manual

Repair or Replace?

However due to their age, it is worth considering whether it is economically viable to repair the unit or spending that little bit extra and replacing it with a current model with a long warranty; especially as newer gas hot water systems such as the Bosch range have a between a 5 and 6 star energy efficiency rating compared to the Pyrox unit which would have been around a 3 star energy rating.

  • LIKE A SINK HEATER – The Topliner 400 will deliver 3.2 litres per minute of hot water at 55°C— – USING JUST ENOUGH GAS.
  • LIKE A BATH HEATER – The Topliner 400 will deliver 6 litres per minute of hot water at 55°C” – USING ABOUT 60% OF ITS TOTAL GAS INPUT.
  • LIKE A FULL HOT WATER SERVICE – The Topliner 400 will deliver up to a generous 10 litres per minute of hot water, that’s 600 litres per hour of water at 55°C— – USING ITS TOTAL GAS INPUT. You only pay for the water you use – you can’t run out.
  • NO FLOOR SPACE NEEDED: Connect to an outside wall.
  • PYROX HOT WATER EFFICIENCY: At least 15%* better than Australian Gas Association minimum performance standards.
  • FLEXIBLE LOCATION: Your Topliner 400 can usually be sited close to the most used draw off points. This reduces energy wastage through long pipe runs.
