Frequently asked questions

• Should I get a direct or indirect system?

  Direct systems heat the water itself and suit coastal areas without frost. Indirect systems use a separate heat-transfer fluid that won’t freeze, so they’re recommended for colder inland areas , though they cost more.

• Is a solar geyser worth it compared to a heat pump or gas geyser?

  A solar geyser has the lowest running costs, since the sun does most of the heating for free. Heat pumps work well in any weather but use some electricity, while gas geysers depend on gas prices. For most homes with good sun exposure, solar offers the best long-term savings.

• What warranty comes with it?

  Warranties vary by brand, but a common example is Kwikot, which offers 5 years on the tank and 2 years on the collector. Installers usually add their own workmanship guarantee.
