NS-300WB The normal footprint on a standard pitched roof of 21˚is: Flat roof (frame sits at 45˚) Foot print 1650D x 2450W x1100H no tank | 1600mm with tank : 350mm header tank/breather pipe Pitched roof (frame sits at 21˚) Foot print 1950D x 2450W x1100H no tank | 1600mm with tank : 350mm header […]

We are really keen to get a system however, as mentioned I do want to flat mount onto the roof rather than with a platform.   If the roof is flat (up to 15˚) the NS-200WB/22 SLIMLINE version will sit flattest on the roof with the tubes being at approximately 22˚.   If you have a pitched […]

Evacuated tube solar collectors offer several advantages over traditional flat plate solar collectors for hot water production, particularly in cooler climates and situations where maximum efficiency is desired. Advantages of Evacuated Tube Solar Collectors 1. Higher Efficiency in Cold Weather The vacuum surrounding each tube acts as an excellent insulator, significantly reducing heat loss to […]

When choosing a solar hot water system, not all collector technologies deliver the same performance. Evacuated tube collectors offer several significant advantages over traditional flat panel systems, particularly in Australian conditions where reliability, flexibility, and year-round performance are important. Superior Performance in Cooler Conditions Evacuated tubes are designed with a vacuum insulation layer around each […]

Hi Donovan, Residential delivery normally incurs significant surcharge, usually $400-$600 a tailgate is normally also required which incurs further costs. Outside of that, the reason we do depot collection (or commercial business address with a forklift) is that it minimises any chance of damage. Forklift to forklift has proven 98% success rate, residential and not […]

Hi Narisha, I would really need a bit more information on your situation to try to identify if there is an issue or if it is just seasonal solar depreciation. We had your tank installed last year. Where are you? What model HWS What methods are you using for boosting in winter Recently, in the […]

Hello. Just wondering what the header tank is for? Regards, Bruce   Hi Bruce,   With our NS-100/200/300WB range, the header tank is designed to refill the main tank in the event of evaporation or boiling. The main tank uses water as the heating medium, the water from there does not go into the house, […]

Vaughan asks… “I am looking to use a solar heater for an industrial purpose. I want to circulate hot water through a heat-exchanger (stainless steel pipe) to keep a tub of bees wax at approximately 80 – 100 deg C.” – We were involved in a similar project for the purpose of melting lard for […]

Boiling is a normal part of vacuum tube systems.   Time of year for boiling will differ with regions of Australia as well as time of year. In 2017 Mt.Isa had similar times for boiling as Tasmania, however Tassie boiled in winter where Mt. Isa didn’t.   It is not necessarily the hottest days, it’s […]

New NS-200WB install on a beautiful property in Wallan. Current hot water cost >$100 p/w. This should drop it by at least 60% #solarhotwater
