52S300 Hiline Solar: Key Benefits

Key Features

The 52S300 Hiline® range is available with either in-tank electric or continuous flow gas boosting. Boosting is a back-up feature that provides hot water during poor weather periods. The electric boosted models will provide a specified boost volume, with larger models designed to suit larger hot water loads. The gas boosted models feature an inline 6-star 24L/min continuous flow gas booster, which only turns on to heat water when the water temperature flowing through it is less than 60°C.

  •  Space saving roof mount design
  •  Reliable, low maintenance operation
  •  Energy Efficient – cuts energy use by up to 85^%
  •  Eligible for Government rebates and incentives

 

* The suggested price is comprised of RRP less the applicable solar incentive and excluding installation. Solar incentive value applies to 52S300/2NPT system in Zone 3.

^ Energy savings of up to 46% to 85% shown are based on Australian Government approved TRNSYS simulation modelling using a medium load. Savings and incentives will vary depending upon your location, type of Solahart system installed, orientation and inclination of the solar collectors, type of water heater being replaced, hot water consumption and fuel tariff. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff.

How the Roof Top Solar Systems Work

Model Type

The solar Hiline™ water heater is designed for both the solar collectors and the solar storage tank to be roof mounted. The solar storage tank has a Colorbond jacket and is suitable for installation with the NPT200 solar collectors.

The system does not have freeze protection. The system is not suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 5°C (41°F). This system has NO WARRANTY for freeze damage. In areas that are prone to frost / freezing, a Closed Circuit system should be used.

This water heater is designed to be installed as an electric boosted solar water heater with its booster heating unit connected to a power supply, however it may be installed with an in-series continuous flow or storage booster. If this water heater is installed with an in-series booster, then the electric booster heating unit will not be connected to a power supply.

Solar Operation

The solar Hiline system has its vitreous enamel lined solar storage tank installed on the roof directly coupled to the solar collectors. It works on the simple scientific fact that hot water rises. As the sun heats the water in the solar collectors, the increase in temperature causes the water to rise through an insulated copper pipe into the storage tank. This allows cooler water from the solar storage tank to flow into the solar collectors to be heated by the sun‟s energy. This process continues while solar energy is available and until the water in the solar storage tank reaches a temperature of approximately 75°C.

Automatic safety controls are fitted to the water heater to provide safe and efficient operation. The Sunstat valve limits the water temperature in the solar storage tank to a maximum of approximately 75°C. The valve:

  • Limits excessively high (scalding) water temperatures.
  • Reduces the discharge of hot water from the temperature pressure relief valve caused by high water temperatures.
  • Prevents the over temperature energy cut out on the electric thermostat from activating unnecessarily.

Orientation of Solar Collectors

To help maximise system performance, solar collectors should be installed with an optimum orientation facing true north (in the southern hemisphere) or true south (in the northern hemisphere). Always check for true north or true south using a compass or other suitable device.

To help maximise system performance, solar collectors should be installed with an optimum inclination. This is equal to 90% to 100% of the local latitude angle when collectors are oriented within 60° of true north or true south, and between 10° and 20° if the collectors are oriented between 60° and 90° from the optimum orientation. Generally, improved summer performance is obtained from an angle of inclination less than the optimum angle and improved winter performance is obtained by an angle of inclination greater than the optimum angle. If the angle of inclination varies by 20° from the optimum angle, the solar collectors will receive about 10% less total annual solar radiation.

Solar Boosting

In-Tank Boosting

An isolating switch is installed in the electrical meter box for an electrically in-tank boosted model. This should be left switched on to allow the booster heating unit to operate if required. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the colder months. The booster heating unit will only activate if heating is required and power is available from the switchboard. When the water is below the thermostat setting, the booster heating unit will turn on and heat the water. The booster heating unit will automatically turn off when the temperature of the water reaches the thermostat setting. If the water temperature drops below the setting again the booster will re-activate.

In-Series Gas Boosting

An in-series gas booster (also known as an instantaneous gas booster) can be installed between the solar water heater and the hot outlets in the house. This booster should be permanently active. The booster senses the temperature of the water passing through it: if the water temperature is above its temperature setting it does nothing; if below it will automatically heat the water up to the preset outlet temperature setting. This device ensures hot water delivery for a variety of hot water demands without the need for user intervention while enabling maximum solar energy contribution to the water heating.
