Why Solar is a Good Idea

Solar water heaters, also known as solar domestic hot water systems, are a cost-effective solution to generate hot water for an entire household. These systems may be used in any climate, and sunshine – the primary fuel source – is entirely free!

Your average solar water heating system includes a storage tank and a series of solar collectors – mounted on the roof or otherwise. There are two types of systems: active, which uses circulating pumps and controls, or passive, which does not. Either one is a smart choice for today’s homeowners.

Most solar water heaters require a well-insulated tank. Each tank has an additional outlet and inlet connected to and from the collector. In a two-tank system, the water heater preheats water beforehand. In a one-tank system, the backup heater is combined with the storage in a single tank. Depending on space requirements, you may opt for either setup. There’s no wrong answer here!

Overall, solar-powered heating solutions are becoming an efficient and cost-effective tool. Those who make use of such a system often enjoy exponential savings throughout the year. Your cost of installation will be quickly recouped over time as your monthly utility bills will decrease.

What is The Lifespan of a Solar Water Heater?

A solar water heater can last anywhere from 15 to 25 years, with proper maintenance and upkeep. If a solar water heating system is installed and maintained correctly, it can provide a reliable source of hot water for many years. On the other hand, lack of proper maintenance and upkeep can significantly shorten the lifespan of a solar water heater.

Inspect and maintain your solar water heater at least once a year to ensure it is functioning properly and to identify any potential issues early on. This will help extend the life of your solar water heater and ensure that it continues to provide hot water efficiently for many years to come.

Just like any other appliance, regular maintenance is key to prolonging the lifespan of a solar water heater. So, if you want your solar water heater to “live long and prosper”, make sure to give it the attention and care it deserves.
