Solar panels are getting cheaper day by day in Pakistan and after 3-4 months summer will end. People are looking for something that can help them save their money and solar water heater is one of them the solar water heater price in Pakistan is starting with Rs. 115,000 while a high quality solar water heater will cost Rs. 230,000.
| Tank capacity in liters | Estimated Price |
|---|---|
| 150 | 115k |
| 200 | 230k |
| 300 | 360k |
If you can afford one for your property let’s discuss in detail on how you can save your money after installing a solar heater in Pakistan.
Solar Water Heater Price in Pakistan (How it Works?)
Nobody wants to use their heater using gas or electricity because it costs them way to much and solar heater in Pakistan basically works after absorbing sunlight and converting it into the solar energy and then using that energy it heats the water.
Solar Heater vs Traditional Heater
As I mentioned above the on “What is a Solar Water Heater” that solar heater use clean energy to heat the water and it can only be used when the sun is out and no clouds are near your area while a conventional heater uses the gas or electricity which is available anytime. However, solar collectors inside the solar heater can’t power your appliances like traditional systems.
Types of Solar Water Heater in Pakistan
You should know why it is important to know what type of solar heater you need for your property and which one will work well for you and after knowing that this will help you save more more than you imagine.
There are two types of solar water heaters in Pakistan.
- Flat Plate Collectors (FPC)
- Evacuated Tube Collectors (ETC)
Flat Plate Collectors
The way flat plate collectors work is very simple judging by the name it has a flat dark surface which gets hit by suns heat and it absorbs it and try to collect as much energy as possible and then that energy help to heat the water that is flowing in it.
Evacuated Tube Collectors
The number of rows you can see in the image are the heat pipes (glass tube) inside which a plate is placed that absorbs the sunlight and that is energy is then transferred to heat exchanger through heat transfer in that exchanger the cold water is entered and will come out warmer after passing through it
Efficiency and Maintenance of Solar Water Heaters
Difference between both Types
| Aspect | Flat Plate Collectors (FPC) | Evacuated Tube Collectors (ETC) |
|---|---|---|
| Efficiency | Moderate (70%) | High (90%) |
| Cost | Lower (approx. PKR 50,000) | Higher (approx. PKR 80,000) |
| Maintenance | Lower (approx. PKR 2,000/year) | Slightly higher (approx. PKR 2,500/year) |
| Cost | Durable, sturdy design | Very durable with vacuum insulation |
| Durability | Effective in sunny conditions | Highly efficient in both sunny and cloudy |
| Performance | Uses flat-plate absorbers | conditions |
| Technology | Moderate | Uses evacuated glass tubes |
| Heat Retention | Easier and less complex | Excellent due to vacuum insulation |
| Installation | Suitable for residential and | Slightly more complex due to vacuum tubes |
| Applications | commercial use | Ideal for residential and commercial use |
| Appearance | Flat, larger surface area | Tubular, more compact design |
How Much Can a Solar Water Heater System Save You?
The summer as we all know will end in 3-4 months and winter will start in Pakistan. The usage of a normal geyser whether it is run on gas or electricity will cost you way more than you think also as of 6th July 2024 the electricity cost will be increasing so there is no way you need to run your geyser on that.
If you are going to use gas to for it that will also cost you Rs. 12,000-22,000 a month which is also costly. You can save yourself and your money after investing on solar heater and use warm water all winter without wasting any money.
Conclusion
Now lets see which one is good for you. The Flat Plate Collectors is very cheap and easy to install and works really well when the sun is out but the problem you can. face is with efficiency it because it is flat the performance decreases when the sun is not above those flat plates which absrobs the sunlight.
Evacuated Tube Collectors has no problem when absorbing the sunlight because it has tubes that you can see in the image with and those tubes are cylindrical in shape. When sun rotates it can easily collects the energy in any direction which increases the performance of heating the water inside the heat exhanger.
