  11. Where should the gas tank be installed?
  12. The gas tank can be installed close to the water heater, in this case the normal 8mm rubber gas pipe can be used. The gas tank can also be installed distant from the unit, in the case of the gas tank being installed more than 5 meters away please contact our customer support, due to the fact that the gas pipe has to be sized according to the total distance of the same pipe.

  13. What are the benefits of purchasing a Rinnai gas water heater?
  14. Rinnai provides the customer with a high end quality water heater, the unit uses less gas consumption when compared to other traditional gas water heaters, and this is due to the modulating gas valve which enables the burner to use the least gas possible, taking into consideration the water flow rate, input temperature and desired output temperature.

  15. Does the unit need a flow pump to spark and ignite?
  16. No, not necessarily, almost all the units are connected to the roof tank and fed through using gravity, and this is due to the fact that the unit is equipped with a flow meter, which enables the water heater to spark and ignite once the flow rate has exceeded the 2.7ltrs /min.

  17. Can it be installed with a solar water heater?
  18. Yes, the gas water heater can be integrated with any type or brand of solar water heater. The unit will regulate automatically the burner according to the inlet temperature, thus if the gas water heater is set to 40 deg, and the solar is heated up at 50 deg, the gas water heater will not ignite and let the water passing through freely. In the event of the solar heating up the water half way through, for example from 10 deg the solar will heat it up to 25 deg, and the water heater will be set to 40 deg, it will automatically ignite and heat up by 15 deg to 40 deg which is the desired temperature, thus consuming half the gas.
