Solar Hot Water System Options

At Ecoplus, we offer quality solar hot water systems to suit your individual requirements: Split Systems (Evacuated Tube & Flat Plate) and Non-Split Systems (Close Coupled).

1. Split Systems

A. Evacuated Tube Solar Collectors Split Systems which offer:

  • Extreme efficiency in non-optimal conditions (e.g. cool and cloudy)
  • Top performance in winter
  • Heat retention of up to 97%
  • A ground tank that makes them Ideal for difficult installation sites
  • Although north facing is preferred, they also work facing NE, E, NW
    and W
  • Resistance to frost and hail
  • Individual tubes can be replaced if damaged
  • A collector with a series of tubes and two layers of glass between them creating a vacuum and preventing heat loss
  • Tubes containing copper pipes and holding liquid that superheats, transferring the heat to water that’s circulated from the ground tank.

B. Flat Plate Solar Collectors – Split Systems:

  • Are the most common
  • Can produce up to 80% of savings in terms of hot water costs
  • Also have a ground tank
  • Operate at maximum efficiency when the sun directly hits the panel
  • Are less efficient in winter (i.e. heat loss)
  • Look better than non-split s, close coupled systems
  • Differ to evacuated tube systems due to actual tank’s water flowing through the panels
  • North facing is preferable
  • Are susceptible to frost damage due to water flow through panels; however, Ecoplus supplies only quality systems with good frost protection

2. Non-Split System

A. Close Coupled Systems:

  • Have the water tank / cylinder positioned on roof alongside the solar panels (non-split system)
  • Uses the sun to heat the collector panels, with the heat being transferred to water in the cylinder
  • Are economical
  • Experience a reduction in efficiency in cool and cold climates
  • Typically use mains pressure
Choosing a Solar Hot Water System: Key Considerations

When choosing a Solar Hot Water System that’s right for you, some of the following should be considered:

  • Roof space (suitability and space)
  • Frost risk
  • Number of people residing in the home
  • How much hot water is required
  • Water consumption patterns (e.g. is everyone using the hot water at once)
  • Efficiency of the water heater system
  • Purchase and operating costs
