Diy Solar Water Heater: 10 Designs And How To Build Them
Solar water heaters use naturally occurring sunlight to heat the water that flows through them. This is a more environmentally friendly and direct method compared to using electricity and gas. They can be more efficient because there is no energy loss by converting one energy form to another, for example when electrical water heaters are powered by solar panels. Best news is you can build one yourself! DIY solar water heaters are incredibly easy to make.
What makes them even more exciting is that it is relatively easy to build them yourself. In this article, we will discuss a number of possible solar water heaters that anyone with some basic handyman skills can make. Of each of these, we will briefly discuss their main characteristics and how to build them.
Facts About Residential Solar Water Heating Systems
Solar thermal systems heat water for household use with clean energy from the sun. If you have an unshaded area of your property that faces south, southeast, southwest, or even west, you can install a solar water heater. Here are four facts about solar-powered water-heating systems.
1. Solar Water Heaters Use Energy Collectors
All solar water heaters include collectors where tap water heats up. The best collector for your home depends on your property, climate, and intended use of the hot water.
The three main types of solar water heater collectors are:
Flat-plate collectors are the most common in Florida. Flat-plate collectors are waterproof boxes fitted with dark absorber plates. Flow tubes positioned over the plates carry tap water over the heated plates and out to household plumbing lines.
ICS systems are sometimes called batch systems. Black tubes or tanks are in a waterproof box to preheat water with solar energy. Heated water exits the ICS collector and enters a backup water heater.
Evacuated-tube solar collectors use special glass tubes, metal tubes, and fins to absorb solar energy and reduce heat loss. The evacuated-tube collector system relies on the vacuum created between the glass and metal tubes to retain heat.
All three types of solar energy collectors rely on water storage. Solar energy systems are either active or passive, regardless of the collector type.
2. Active Solar Systems Use Pumps

Here Are 23 Ways To Save On Your Electric Bills Right Now
How quickly a solar water heater will pay back its cost in energy savings depends on the local cost of energy, whether you heat water with gas or electricity and even when you use hot water. You can find detailed instructions for calculating your payback period, but solar water heaters take longer to pay for themselves if they replace natural gas water heaters than if they replace electric ones. If your hot water costs are high, you could recoup your expenses in a matter of years, much faster than the 20 or more years a solar water heater can operate.
A more cost effective way to go solar could be to run an electric water heater with electricity-generating solar panels on your roof. Solar panels are getting cheaper and they can replace the power needed not only for heating water, but for any of your other home electricity needs. A rooftop solar array can be sized to include the needs of an electric water heater and, depending on the efficiency of the water heater, may require only a slightly larger solar array. And, your utility might pay you for any excess electricity you generate from solar panels. Any excess energy a solar water heater creates won’t be compensated.

How Does It Work
With the components of a solar water heater identified, this is how it works. The water heater absorbs the suns light via the collectors placed on the roof of the house. This light eventually gets converted to heat. The water heating system circulation comes into play in this part of the process as it is responsible for passing the heat to a water reservoir or tank. The exchange is activated by the thermal controller once it detects the collector being hotter than the water stored inside the container. This is a prevention mechanism when it comes to electricity usage, and this stops the system from overheating.
The efficiency of the heat collectors is at its peak during midday when there are no clouds, and the collectors are facing south. If the sunlight is insufficient, the water gets preheated, and an alternative system steps up to let the water reach the desired temperature.
Advantages Of Using Solar Water Heater
In contrast with the customary water heaters, these are substantially more cost-effective as it needs characteristic assets for warming purposes, for example the sun. Consequently a large portion of the customers are link to spare the expense of gas and power bills.
The unit controlled by the sun can be used to warm water in homes where there’s a lack of gas and power flexibly. One more best advantage of utilizing solar water heaters is that it’s eco-accommodating. It’s doesn’t produce such a toxic gas while working.
In contrast to customary water heaters, these are more tough and keep going long more.
However, legitimate consideration and support are expected to ensure effective working of the solar water heaters. It’s best proffered to have a specialist to introduce the water heaters in your home. However, detached water frameworks need less upkeep, dynamic water warming frameworks need support for smooth and appropriate working. Because of its high effectiveness just as dependability, the solar water heater is utilized by millions all around the globe.

How Many Solar Panels Do I Need To Run A Water Heater
Most homes will need three standard-size solar panels for an output of 1,500-watts of energy per hour. However, to run a solar water heater you would use collectors instead of panels. Panels are used for photovoltaic solar energy systems that absorb energy from the sun into PV cells in panels that cause electricity to flow.
What Is A Solar Water Heater
An effective way to heat your water without the use of your energy grid, solar water heaters draw power from the sun. Unlike traditional water heaters, solar water heaters utilize solar collectors on your rooftop to transform sunlight into solar energy, which is then used to heat the water in your home.

Passive Solar Water Heating Systems
Passive solar water heating systems are typically less expensive than active systems, but they’re usually not as efficient. However, passive systems can be more reliable and may last longer. There are two basic types of passive systems:
- Integral collector-storage passive systemsThese consist of a storage tank covered with a transparent material to allow the sun to heat the water. Water from the tank then flows into the plumbing system. These work best in areas where temperatures rarely fall below freezing. They also work well in households with significant daytime and evening hot-water needs.
- Thermosyphon systemsWater is heated in a collector on the roof and then flows through the plumbing system when a hot water faucet is opened. The majority of these systems have a 40 gallon capacity.
Active Circulation Solar Water Heaters
Active circulation systems are popular solar water heaters for residential homes. As mentioned, they use a pump to create hot water and circulate it throughout the home. In general, active circulation systems pump water between your home, the solar collectors, and the storage tanks. Active circulation solar water heaters can use one of two methods to heat water: direct circulation and indirect circulation.
- Direct circulation: Pumps circulate water through solar collectors and into the home, where homeowners can then use the hot water.
- Indirect circulation: Pumps will also circulate water through solar collectors. However, they use a non-freezing heat transfer liquid, which is beneficial for homes in areas with freezing climates.
Pros and Cons
|Works well in colder climates||Use an electric heat pump, which requires electricity|
|More efficient in heating water|
