Here are three things to take into account before purchasing your solar-water heaters in Paphos.
The most popular water heaters are storage tanks that feature a tank where water can be stored and heated when it’s needed for use. In contrast, water heaters with a tank don’t store water and warm up the water as it goes through a group of coils.
When you are looking to purchase a solar panel heater, one of the things you need to do is decide on the capacity. This will determine how much heat the unit can produce and how effective it will be. The most important factor to consider is the size of your home. If you have a large home, you will need a higher capacity unit in order to heat it effectively. You also need to consider the climate in your area.
One of the most important factors is the energy efficiency of the unit. You will want to make sure that the unit you choose is designed to be as energy efficient as possible. The most efficient solar-water heaters will be able to generate more hot water with less sunlight, which means that they will be more cost-effective in the long run. The installation and price of solar-water heaters normally cost most than conventional heaters, but it’s an investment that pays off in the long run because having a solar heater can reduce your energy and electricity bills by 40-80%. The amount of money you save also depends on your usage of water. Plus, you don’t have to worry about gas price spikes anymore.
Let’s go over two methods of how to measure the efficiency of your solar-water heater.
The solar energy factor (SEF) is a measure of a solar-water heater’s energy efficiency. It is calculated by dividing the amount of heat delivered by the solar-water heater over a period of time by the amount of solar energy incident on the solar collector during that same period of time. The higher the SEF, the more efficient the solar-water heater. Keep in mind that the SEF doesn’t tell you everything about a heater’s performance. Though, consider things like how well the unit retains heat and how easy it is to maintain.
The solar fraction (SF) is a measure of a solar-water heater’s energy efficiency. It is the percentage of the sun’s energy that is converted into usable heat energy by the solar-water heater. For example, if a solar-water heater produces 1,000 BTUs of heat energy in a day and there are 4,000 BTUs of sunlight falling on the solar collector, then the SF would be 0.25, or 25%. The higher the SF, the more efficient the solar-water heater. Solar-water heaters with an SF of 1.0 are 100% efficient which rarely happens, the most common numbers are between 0.5 and 0.75.
Consider the annual operating costs and compare various systems before investing in a solar-water heating system. You can use this to calculate the energy savings and payback period of an investment in a more energy-efficient system, which will likely cost more upfront.
Knowing the system size needed for your home is necessary before you can choose and compare the prices of different systems.
You need the following to calculate a solar-water heating system’s annual operating costs:
Operation and maintenance costs for solar-water heaters are typically low, making them a cost-effective option for many homeowners and businesses. In addition, solar-water heaters can last for 20 years or more with proper maintenance, making them a wise investment for the long term.
