High Pressure Direct System 200lt – Frost & Frost Free – w/
For 20 x Integrated Evacuated Tubes
Inland and Coastal Areas
This direct system can be used in frost and frost-free locations and where the water quality
is good (less than 600ppm Total Dissolved Solids/Minerals).
The direct system, is where the water to be used in the household (hot water) circulates through the solar vacuum tubes manifold, transferring solar energy into the storage tank of the solar water heater.
This direct system is installed as a Close Coupled System (thermosyphon circulation), where the solar water heater and integrated evacuated tubes gets installed outside on the roof.
Features
The Apollo Solar Water Heater Direct System complies with SANS 1307, is SABS 400kPa approved and can be used as a close coupled system only.
5Year System Warranty (T's & C's Apply)
SABS Approved
The inner cylinder is manufactured from 2.2mm stainless steel.
Polyurethane insulation between the inner cylinder and outer casement reduces energy and heat loss.
1x aluminium sacrificial anode is fitted for corrosion protection.
The solar water heater does not have an isolator switch fitted to the solar tank. An additional 2kW element, thermostat and isolator switch needs to be added to the system for the domestic hot water application (electric backup) in conjunction with an array of solar vacuum tubes.
The 2kW booster element ensures that the solar water heater can be used as a conventional electric water heater and as a solar water heater.
The solar water heater thermostat will automatically switch on when the incoming hot water from the solar vacuum tubes, has not reached the set temperature setting on the thermostat. This will occur on cloudy days and at night when the water temperature drops in the solar water heater or when hot water is drawn off and cold water enters the solar water heater. The element can also be controlled with a digital geyser timer and set to specific time intervals for the element to switch on.
