Hey there! As a supplier of 120L solar water heaters, I often get asked about the dimensions of these nifty appliances. So, I thought I'd write this blog to break it all down for you.
First off, it's important to understand that the dimensions of a 120L solar water heater can vary based on a few factors. The design, the type of collector used, and the overall build quality all play a role in determining the size.
Tank Dimensions
Let's start with the water tank, which is the heart of the solar water heater. A 120L tank is typically cylindrical in shape. On average, the height of a 120L water tank can range from about 1.2 to 1.5 meters. This height gives it enough space to hold the 120 liters of water while still being relatively compact enough to fit in most residential or commercial settings.
The diameter of the tank usually falls between 0.4 to 0.6 meters. A smaller diameter might make the tank taller and slimmer, while a larger diameter will result in a shorter and wider tank. The choice of diameter often depends on the available installation space. For instance, if you have a narrow but tall area, a tank with a smaller diameter and greater height might be the way to go.
Collector Dimensions
Now, let's talk about the solar collectors. These are the parts that absorb sunlight and transfer the heat to the water in the tank. There are different types of collectors, such as flat - plate collectors and evacuated tube collectors.
Flat - plate collectors are quite popular. They are usually rectangular in shape. A 120L solar water heater with a flat - plate collector might have a collector that is around 1.5 to 2 square meters in area. The length could be around 1.5 to 2 meters, and the width around 1 to 1.3 meters. You can check out our Flat Solar Water Heater for more details on this type.
Evacuated tube collectors, on the other hand, consist of a series of glass tubes. The number of tubes and their length can vary. For a 120L system, you might have around 15 to 20 tubes. Each tube is usually about 1.5 to 2 meters long. The overall dimensions of the evacuated tube collector array will depend on how the tubes are arranged.
Portable and Non - Pressure Options
We also offer Portable Solar Water Heater and Non Pressure Solar Water Heater options. The dimensions of these can be a bit different.
Portable solar water heaters are designed to be more compact and easy to move around. The tank might be a bit smaller in size, and the collectors are usually more lightweight and have a smaller footprint. They are great for camping, small cabins, or places where you need a temporary hot water solution.
Non - pressure solar water heaters are designed to operate without high - pressure requirements. The dimensions of these can be similar to standard 120L models, but they might have different internal components that allow them to work under lower pressure conditions.
Installation Considerations
When it comes to installing a 120L solar water heater, the dimensions are crucial. You need to make sure you have enough space on your roof or in your yard for the collectors. There should also be enough room for the water tank, preferably in a well - ventilated area.
You'll also need to consider the clearance around the heater for maintenance purposes. You should be able to access all the components easily, including the valves, pipes, and the tank itself.
Advantages of a 120L Solar Water Heater
Now, why should you choose a 120L solar water heater? Well, for starters, it's a great size for a small to medium - sized family. It can provide enough hot water for daily showers, dishwashing, and other household needs.
Solar water heaters are also energy - efficient. They use the sun's energy to heat the water, which means you'll save on your electricity or gas bills in the long run. And let's not forget about the environmental benefits. By using solar power, you're reducing your carbon footprint and contributing to a greener planet.
