Clean and efficient water heating. As you know solar energy is free and abundant, not to mention it has no carbon footprint. If you want to get away from gas and hydropower, solar water heating is an excellent option, especially if you live in an area that receives a lot of sunshine, as approximately 80% of the radiation is turned into heat energy.
Returning investment. Although solar power requires an initial investment to install, it replaces the energy you would otherwise be purchased from the power company. Depending on your location, the investment will eventually pay for itself in electricity savings. It’s estimated that with a solar water heating system, your water heating bill would be able to drop up to 80%.
Easy to maintain. The solar water heating system does not require much maintenance. All you need to do is circulate a water softener in the pipes every 3 years.
Quiet. There are few moving parts, but in general, the system does not produce much noise.
Non-intrusive. Unlike other solar technology that required the installation of up to 16 solar panels, the solar water heater needs two or three. You’ll need some extra space for the storage tank if you’re using the passive method, but other than that it doesn’t take up much space.
Renewable heat incentive. Domestic and commercial properties are entitled to claim the renewable heat incentive. This means that you will be paid for generating your own heat energy regardless of whether you use it all. There’s a user-friendly calculator available which tells you how much you can earn through this scheme. It can be hundreds of pounds a year.
Cons of Solar Water Heaters
Financial costs. Unfortunately, purchasing and installing the system is still a serious investment, and it would take up to a few years before you start noticing a financial benefit.
Depends on the climate. Like all solar energy, its effectiveness and output is highly dependent on the hours of sunshine your area gets during the day.
Only heats water. This system cannot be used to power other electrical devices other than heating the water.
