The Streamline 413MLV system is available Solahart's 'L' solar collectors to harvest the sun's heat and transfer it to the water. The L collector with its black powder coated aluminium absorber plate provides economical service in low to high solar gain areas.
Solar energy is transferred directly to the water as it is moved through the collectors by an electric circulator and the heated water is stored in the ground mounted MDV series tank. The electric boosted models are equipped with an in-tank element to ensure a supply of hot water during periods of poor or no solar gain. Alternatively the system can be installed as a preheater with an inline Solahart gas booster water heater.
- Stylish slimline design
- Minimum visual impact
- Can cut water heating energy use by up to 65%^
- Choice of collectors to suit high to low solar gain areas
* The suggested price is comprised of RRP less the applicable solar incentive and excluding installation. Solar incentive value applies to 413MLV system in Zone 3.
^ Energy savings of up to 65% shown are based on Australian Government approved TRNSYS simulation modelling of a Solahart 413MLV and using a large 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.
† Solahart Warranty Details: 5/3/2 warranty; 5 year cylinder and collectors supply, 3 year parts, 2 year labour; applies to a single family domestic dwelling only. Without limiting these periods, a 5-year whole-of-product warranty applies where a rebate has been received under Solar Victoria’s Solar Homes Program for installations from 1st July 2023.

How Split System Solar Water Heaters Work
As the sun heats the water in the solar collectors, the increase in temperature activates the circulator. The circulator switches on whenever the water in the solar collectors is hotter than the water in the solar storage tank. The circulator moves the hotter water from the solar collectors through the solar hot pipe to the solar storage tank and the cooler water from the solar storage tank is circulated to the solar collectors via the solar cold pipe to be heated by the sun’s energy.
This process continues whilst solar energy is available and the water in the solar storage tank requires heating. The circulator will deactivate when the water temperature in the solar storage tank is around 70°C to 75°C. The water heater will then enter Over-temperature operation.
During normal operation if the amount of solar energy available reduces, such as when the sky becomes very cloudy or the sun becomes lower in the sky in the late afternoon, and the water no longer gains usable heat from the solar collectors, the circulator will deactivate. The water heater will then enter standby mode.
The purpose of Freeze Protection operation is to prevent freezing of water in the solar collectors and solar pipe work in very cold conditions. The water in the solar collectors will cool during periods of no solar gain. In very cold conditions, such as overnight and very early in the morning before sunrise, the water temperature can approach freezing point.
If the hot sensor measures that the water temperature in the solar collectors is approaching freezing, the circulator will activate. Water from the solar storage tank, containing more energy than the water in the solar collectors, will circulate through the solar collectors keeping the water temperature above freezing point. The circulator will remain on for some minutes and until the hot sensor measures a water temperature at a safe level above freezing. When both of these conditions are met, the circulator will deactivate. The water heater will then enter standby mode.
