Solar Hot Water Heating System


Our solar hot water heating system uses solar tubes on the roof to heat the water before sending it to the cylinder via a small pump.

This is an easy alternative to a conventional hot water cylinder set up. It includes a cylinder, solar smart hot water controller, LCD display, pump and solar tubes. Something here about ease of installation and not damaging integrity of roof.

Unlike traditional solar PV, solar tubes allow up to 4 times the amount of energy to be harvested using the same roof area. The sun’s power goes straight into the hot water cylinder via a pump – no need for an expensive battery to store the energy.

Installation costs are similar to a heat pump ($5-$6k) but the Smart Hot Water Company solar hot water system is significantly cheaper to run than a heat pump.

In mild climates like Auckland a solar hot water system is expected to provide at least 80% of a households hot water needs. That means 80% of your hot water is free.

In winter 2 – 3 days of dark, cloudy weather may require the electric element boost to engage and top up the power. If there was a high demand for hot water overnight the electric element can engage to top up the power.

The small pump is very quiet (unlike some heat pumps) and will run continuously without the need for maintenance. The only moving parts are in the small water pump and this is likely to run for at least 7 or 8 years before servicing is required.

Problem: I need cost effective renewable energy source to heat my hot water especially for larger hot water draws. Solar Electric is very expensive for this scenario and I don’t have enough roof space anyway. 4kW is about the limit

Solar Hot Water Heating System

Solution: Solar hot water is actually an excellent product choice for this;

  • It is 400% more efficient than solar electric
  • Less roof space for same energy harvesting or scale up for much greater energy harvesting at moderate cost. Solar hot water panel costs are much lower than solar electric for the same power.
  • Instead of being limited up to 5kW with solar electric, you can harvest up to 20kW for the same roof area using solar hot water. This is more than enough for large families, ‘bed and breakfasts’ or even space heating
  • Save money, for larger users… a lot of money

The Smart Hot Water Company utilises evacuated tube solar collectors. This advanced technology uses copper ‘heat pipes’ inside toughened borosilicate vacuum tubes. Very strong and efficient.

Solar Hot Water Heating System

Because the tubes are round they harvest solar energy efficiently from much wider sunlight angles, lengthening your harvesting time. The panels are an astonishing 70% efficient at converting the sun energy into heat.

If you use more hot water, then solar hot water is a great investment.

The best part is our advanced Solar Hot Water controllers not only efficiently harvest your solar hot water but the same technology used by the Smart Hot Water controller and Smart Cylinder is present to control your back up electric element in your cylinder.

With the colour touch screen and all its benefits, you can see how well your system has been performing with its inbuilt data logging.
