Solar Water Heater Maintenance Dubai | Solar Water Heater Dubai
A lot of energy is used in the home to heat water. In fact, about 18 percent of home energy use goes towards heating water. It is possible to reduce energy use and the associated costs, by switching to a home solar water heating system.
Such a system does not depend on fossil fuels and takes energy from the sun to heat stored water. It, therefore, saves money, which is a major advantage of solar heating systems. Energy from the sun doesn’t cost anything, so no charge from electrical utilities is needed.
Advantages of Solar Water Heaters
The advantages go beyond cost savings and the availability of power, which are also realized with solar electric systems. Here are a few unique perks of home solar water heating products that may convince you to upgrade your home.
These come in two forms. Direct circulation systems pump household water through collectors, which is then delivered to where needed in the house. They have automatic controllers that sense when sunlight is available. However, the systems are ineffective in temperatures below freezing.
Indirect circulation systems heat water by pumping it through a heat-transfer fluid that doesn’t freeze. It’s then sent through collectors and a heat exchanger. Operational in freezing temperature and in multiple heating applications, they’re often more expensive than direct circulation systems.
Two types are available here as well. An integral collector-storage passive system consists of a storage tank, solar collection unit, and pipes that pump cold water into the collector. It suits a home that needs hot water in the day and evening but also doesn’t work as well in cold outside temperatures.
A thermosyphon system works on the principle of warm water rising and cold water sinking. Warm water in the collector rises into the storage tank, which is a reliable configuration. A downside is the weight of the storage tank, which can be a challenge for contractors working on the roof; the system is a more expensive option as well.
Other advantages include:
Disadvantages of Solar Water Heaters
Maintenance is one disadvantage, although most systems don’t require a high degree of care. However, scaling occurs when there are minerals suspended in domestic water, which build up as calcium deposits in the system. Adding water softeners or mild acidic substances such as vinegar can avoid scaling. It only must be done every three to five years, but this can vary depending on the water quality.
Corrosion is another concern. In open loop hydronic solar systems, oxygen can rust any iron or steel part. The plumbing components are more resistant if they’re made of copper, brass, bronze, stainless steel, plastic or rubber. Storage tanks should be lined with glass or plastic to resist corrosion as well.
Also, active systems can overheat if the size of the storage tank isn’t appropriate for the collector. The general rule is that for each square foot of collector, there should be 1.5 gallons of storage. With that in mind, such a disadvantage can be avoided.
Cost can be another disadvantage. Oftentimes a solar water heating system costs more in terms of purchasing and installation, compared to other types of water heaters. The savings come over the long run because water heating bills can be reduced by as much as 50 to 80 percent. Price hikes, fuel shortages, and other issues with utility-based heat are not a concern either.
Getting the Most Out of a Solar Water Heater
There are many advantages to using a solar hot water systems, and many of the disadvantages can be averted through professional installation. Installers can check the roof to see if it can support the panels. They can also look at shading and other factors that might impact efficiency.
Professional installers can also help you get more out of the system. In addition to a more optimal configuration, they might be able to optimize roof space so water heating elements can be combined with photovoltaic systems. Electricity from these can contribute to additional heating capacity. In fact, combining different types of panels contributes to a high degree of energy efficiency.
Solar water heaters have their advantages and disadvantages, but they are reliable and efficient. Planning and proper installation help homeowners get the most out of them and avoid some of the disadvantages while reaping all the benefits the right system and size can afford.
Like every other big investment, investing in solar thermal requires a bit of research if you want to make a well-informed purchase. Depending on your location, solar water heater dubai will be a very good choice as a supplier in uae. Moreover, you should consider your budget, the size of the house and the type of system that you would like. Get more info at solar water heater maintenance dubai.
