52D300 Hiline Solar: Key Benefits
Most suitable for areas that receive medium to high levels of solar radiation, and are not subject to frost conditions.
Show less
The electric boosted models are equipped with an in-tank element. Alternatively the system can be installed as a pre-heater with an inline Solahart gas booster water heater.

Key Features
The 5D300 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 model will provide a 150 litre boost volume. The gas boosted model features an inline 6-star 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 65^%
- 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 52D300/2NPT system in Zone 3.
^ Energy savings of up to 65% shown is based on Australian Government approved TRNSYS simulation modelling of a Rheem 52D300/2NPT and using a medium load in Zone 3 and apply when replacing an electric water heater. Any savings 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.
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.
In-Series Gas Boosting
An in-series gas booster (also known as a continuous flow 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 gas booster 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. For more information on this booster, consult the owner’s manual for the product.
