Building a solar hot water heater is a fantastic DIY project, especially for someone who is just starting out converting to solar power. Why? For several reasons. To start with, it is easy and limited in scope, allowing the beginner to maintain focus and learn important solar concepts along the way.
It is also very cheap to complete. Considering these factors it has a HUGE and immediate impact on your power bill. Most people don’t realize it, but heating water usually accounts for a full one-third of their monthly energy expense. Only HVAC (air conditioning and heating) uses more energy in the average home.
You can usually build a solar hot water heater for under $100 – pretty good considering that one you have installed professionally will cost well over $1000. The parts are all readily available in your local hardware store or home center.
No special tools are needed. Most DIY’ers have a basic understanding of plumbing and wiring connections, which is all you really need to know to get started. It only takes a weekend to complete and you can be heating water for free on Monday morning.
There is no need to worry about the local climate as solar water heaters are in use all over the world. The design technology has been around a lot of years and is very reliable. Still, it is advisable to have a backup source – just like with any solar powered component -in case of long cloudy periods. You will rarely need your backup because unlike some other solar applications, the tank keeps the water very hot for an extended period of time once it has been heated.
Still, your sunlight and consumption may be different than mine so it makes good sense to always have a backup when using solar power for anything. Luckily, you already have your backup in place. You just keep your existing water heater and use it if/when you need it. Because the unit hardly ever runs it should last for years as your backup source with no concerns or expense.
In addition, your solar water heater will last years longer than a normal gas or electric water heater and require very little maintenance.
Much of the information on the internet about building solar water heaters is just plain wrong.I’ve seen claims that boast about being able to build one for $5. These are usually garbage, held together by wire and duct tape or worse. If you are going to do this project, do it right and make sure you can produce enough hot water for your entire home most of the time.
The honest truth is you can spend less than $100 and save 33% on your monthly energy bill simply by converting your home to solar hot water. Visit our site for more articles on this topic and great sources of information and instruction.
