Here are 3 important questions and their probable answers.
Question 1- How much water do you want to generate?
If your family unit is only one or two persons and activities like washing clothes are infrequent, a minor "batch" or passive system may be better. A quick method to determine your probable household hot water need is to simply multiply family members by 18 gallons. A family consisting four uses around 72 gallons or 360 liters of hot water each day for laundry, cleaning, bathing, and cooking. This number shall help you gauge not merely the collector you need, other than also the reserve tank essential for keeping your family with hot water.
Question 2- Where do you live?
About all of most systems are configured upon expected output of warm water for a specific weather. In sunny, warmer areas as Florida, Arizona, and Southern California, you may generate a tremendous quantity of hot water using a comparatively small system. In colder areas a large collector will be needed, and an active system shall be better to satisfy the home's warm water needs.
Question 3- What is your budget?
The solar heated household water should not have to be expensive. While compared to photovoltaic collection, solar water heaters returns much faster on investment and are very much reasonably priced. For merely a few hundred dollars you may build your batch-style arrangement and even commercially made systems for warmer weathers can be within your means.
