The grid fails on its own schedule, and your fence, cameras and lights go with it. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Collector absorbs sun; tank stores hot water. - Thermosiphon: hot water rises into the tank without a pump. - Pumped (split) systems put the tank indoors. Quick answer A solar water heater has a collector (flat plates or glass tubes) that absorbs sunlight and heats water or a heat-transfer fluid, and an insulated tank that stores the hot water. In most home systems, heated water rises naturally into the tank above the collector (thermosiphon), so no pump is needed. An electric backup element tops up the temperature on cloudy days.

Thermosiphon systems don't need power to heat water; the optional backup element and any pump do. Will I have hot water in the morning? Yes, if the tank is well insulated and sized for your use; the backup element can top it up. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
