What size Geyser do I need?

 These are the sizes that we find work well for most customers:

  • 85 Litre: Staff quarters up to 4 adults / Kitchen
  • 150 Litre: Single person’s flat / En-suite shower room
  • 200 Litre: Family bathroom 2 adults & 2 children
  • 300 Litre: Larger family or people who enjoy frequent deep hot baths!!

 We recommend that a separate unit is installed to supply a kitchen, as if the kitchen shares a geyser with a bathroom and your domestic staff use a lot of hot water during the day, there might not be enough water left for showering / bathing.

These sizes may seem large compared to the electric geyser sizes that you are used to, but remember that the solar geyser will only heat during the day. With an electric geyser, if you drain it completely in the evening, it will be hot again for bathing in the morning (assuming Zesa is on) With a solar geyser you need to make sure that you heat enough water during the day to cover your evening & morning requirements. The units are very well insulated, so the water will stay hot overnight, even in cold winter weather.

Do your prices include installation?

No, Our geyser prices are for supply only, so those customers who want to install themselves or have a plumber already can do that, however most customers use our experienced, professional installation team to install for them. This ensures that the geyser is installed correctly & that the full 2 year guarantee covers not just the the geyser but the installation as well.
For most domestic installations, the delivery & installation cost is $250, Assuming:

  • There is a sturdy, North facing or flat roof to install to.
  • We are replacing an existing electric geyser, i.e. hot water plumbing is already in place.
  • The site is in the Harare area.

If all of these conditions are not met, we are happy to come & do a site visit to provide a detailed fixed price quotation.

What do I need to know when choosing my Solar geyser Supplier?

  • Does your preferred supplier offer the full service, i.e. supply & install, otherwise, who will you contact if things go wrong?
  • Does your preferred supplier really know the product they are selling & if it will suit your requirements?
  • Remember that our units are fully stainless steel – tanks & frames & come with a 2 year guarantee on ALL parts & installation.
  • You will find cheaper units around, but please check the following when comparing quotes:
    • Number of glass tubes – the glass tubes collect the sun’s energy, so fewer tubes mean less heating – Our 300 Litre units have 36 x 1.8m tubes, 200l units have 24 x 1.5m tubes, 150l units have 20×1.5m tubes & the 85 Litre units have 15 x 1.5m tubes.
    • Angle of elevation – For optimum solar collection efficiency the angle of the glass tubes should be similar to the latitude that the unit is installed at. Harare has a latitude of 17 degrees South. Our units have an elevation angle of 25-30 degrees. Other units on sale in Harare are set to at 60 degrees elevation – Ideal for northern Europe, or Cape Town but not great for Harare!
    • Thickness of glass – our tubes are made from 1.6mm thick glass, and are rated up to 25mm diameter hail stones! Some Other manufacturers are only using 1mm thick glass.
    • Installation quality – our installation team have installed over 1000 of these units now & are proper qualified plumbers.
    • Guarantee – some other suppliers only offer a guarantee on the tank – ours covers everything, tanks frames, glass tubes,  pipes, fittings, etc, etc.
    • Spare parts – we keep a full set of spares in stock, so even after the guarantee period will be able to support the product for its full working life.

Why don't you do a smaller unit?

The 85 litre unit is the smallest one we sell for several reasons:

  • If you have a solar geyser with a smaller tank, say 50 litres, there is physically not enough room to connect a sensible number of glass tubes to the tank. The 50 litre units that others are selling have so few glass tubes (I have seen one with only 5 tubes!) that they will not provide adequate heating of even the 50 litres. Our 85 litre unit has 15 glass tubes and will genuinely heat 85 litres of water per day.
  • The installation cost of a solar geyser is usually fixed, irrespective of the size. As the geyser becomes smaller, the installation cost becomes a more significant proportion of the overall cost, making the cost saving of going for a smaller geyser insignificant.
  • When comparing our solar geyser sizes to that of an electric geyser, remember that the solar geyser will heat its capacity once per day, so once that amount of hot water is used up, you will have to wait until the next afternoon before there is hot water again, whereas with an electric geyser, once you have emptied it of hot water, it will re-heat again within a few hours (assuming that Zesa is on!), so for a 100 litre electric geyser, you could empty it 3 times in a day and get 300 litres of hot water, although you will pay for 3 lots of electricity to do that.
  • All solar geysers are less efficient during cloudy days, so it is always worth having a bit more capacity than you think you will need, which will allow you to keep a bit of hot water for the next day in case of cloud.

The cost of our all stainless steel 85 litre gravity solar geyser is $575.
