Solar water heating system (SWH) is a renewable energy source which uses the radiation from the sun to heat water and as been well established for many years. New technical innovations have improved performance, life expectancy, and ease of use of these systems. SWH Systems are designed to deliver hot water for most of the year and are a cost-effective way to heat hot water for your home. They can be used in any climate, and the fuel they use is solar radiation, that it is readily available to everyone, in other words sunshine, and is free. However, in winter there sometimes may not be sufficient solar heat gain to deliver enough hot water. So it is necessary to use a gas or electric appliance as a supplement to heat the water.
In the recent years, many suppliers are offering a Dual System, combining a PV panel next to a solar panel. The electricity produced by a PV panel can be used to power the solar heating pump.
Hot water heated by the sun is used in many ways. The best known use is in a residential setting to provide domestic hot water. SWH has also other applications; Swimming pools are the best beneficiary from the SWH technology as they are in use in summer when the sun radiation is the strongest. Swimming pool systems are simpler; the pool's filter pump is used to pump the water through a solar collector, which is usually made of black plastic or rubber, and the pool stores the hot water. Other applications of Solar Hot Water is commercial use, hotel, nursing home, marina, sports complex, university, park and recreational site, summer camp, factory and industrial site, farm and agricultural site, remote and off grid location...
Benefits of Solar Water Heating
Depending on where you live, using the sun’s free energy you can reduce your hot water energy consumption by 50% to 90%, making a big savings on your energy costs. That’s up to 90% less gas or electricity which needs to be produced by conventional methods. Analysis of the engineering and economics for a Solar Water Heating system shows that the system has a payback period of just two years.
- Save the environment; Using solar energy has a positive impact on the environment by reducing the use of nonrenewable energy sources to heat water, such as gas, coal, oil or nuclear power. Solar energy is safe, efficient, reliable and non-polluting. The consumer has direct control over the system, and unlike conventional water heaters, hot water is available even during a power outage. A family of four, with a Solar Water Heater can save up to 3 or 4 tones of greenhouse gas emissions compared to a conventional electric water heater, so you can imagine the benefits for future generations the planet.
- Grants and Government Incentives; Local, national and EU grants are available in order to support and encourage householders to install Solar Water Heating systems.
Before you start;
Before you decide about installing an environmentally friendly system to generate your own heat, make sure your home is as energy efficient. Very important is to improve insulation in your home and eliminate draughts, making your home more energy efficient makes investment more cost effective.

The proper installation of solar water heaters depends on many factors. These factors include solar resource, climate, local building regulations requirements, and safety issues; therefore, it's best to have a qualified, solar thermal systems contractor install your system. Before you purchase and install a Solar Water Heating system, you want to consider the following: 1. Determine your site's solar resource 2. Size correctly your SWH system 3. Evaluate the economics of a Solar Water Heating systems 4. Estimate and compare system costs 5. Determine the system's energy efficiency 6. Find out local regulations and covenants, When installing a SWH it’s important to consider installing a backup system for cloudy days or for the time of increase demand, freeze protection to prevent damage to the system in winter and over heat protection to prevent the storage tank from overheating. Your Installer or an independent advisor will be able to give you the right solutions concerning SWH.

Passive systems don't require much maintenance. For active systems, discuss the maintenance requirements with your system provider, and consult the system owner's manual. Plumbing and other conventional water heating components require the same maintenance as conventional systems. Glazing may need to be cleaned in dry climates where rainwater doesn't provide a natural rinse. Regular maintenance on simple systems can be as infrequent as every 3–5 years, preferably by a solar contractor. Systems with electrical components usually require a replacement part or two after 10 years. Local, national and EU grants, funds and financial support are available for domestic, community and commercial Renewable Energy projects.
