Low Pressure vs High Pressure Solar Geyser: Which Should You Buy?
Choose a low-pressure solar geyser if your home has a gravity-fed or low-pressure water supply. Choose a high-pressure system if your home runs on mains-pressure water. Low-pressure systems are usually the more affordable option. This guide helps you decide and size the geyser. The Sun Pays has supplied solar equipment in South Africa since 2007 and sells from Rayton, Gauteng.
Low pressure or high pressure?
- Low pressure suits gravity-fed or low-pressure water supplies, such as a tank on a stand or a borehole system that does not run at mains pressure. It uses a small auxiliary tank to keep the main tank filled.
- High pressure suits homes on mains-pressure water, where hot water must reach taps at full pressure.
If you are not sure which supply you have, send us a photo of your current geyser and plumbing and we will tell you which type fits. Detailed specifications: low-pressure geyser specs and high-pressure geyser specs.
How big a geyser do you need?
A common rule of thumb is about 50 litres of hot water per person per day. A 200L geyser typically suits a household of around four people. Hot-water habits vary, so allow extra if you run baths, a dishwasher or a large family.
