Solar Geyser vs Heat Pump
Comparing solar geyser vs heat pump will help you find the right regenerative heating system for your home.
Solar thermal panels absorb heat from the sun, while heat pumps absorb heat from the air (air source) or underground (ground source). Both have many benefits, including the potential to reduce heating bills. However, one may fit your home better than the other.
In this article, we will help you choose between a solar heat pump and a heat pump.
What is a heat pump?
A heat pump is an electrical device designed to extract heat from one location and transfer it to another. Heat pump technology doesn't have to be new. It has been used for several years in countries like Canada. Both refrigerators and air conditioners use heat pump technology. More recently, heat pump technology has been incorporated into water heating with huge dividends.
How does a heat pump work?
If your goal is to save energy and reduce your electricity bills, a heat pump is a good choice. A refrigerator works by taking heat from the inside and transferring it to the outside. Your heat pump operates the same way, albeit in the opposite direction. It absorbs heat from the surrounding environment and transfers it to the water in the tank.
This process increases the temperature of the water while pushing cool air out of the room. This is the main reason why the air outside the heat pump is always cold. This heat transfer method of heating water is very efficient and fast.
Energy consumption and savings
Heat pumps are very effective in saving energy. It is important to note that temperature changes have only a slight effect on its energy consumption rate.
Compared to other traditional types of water heaters (electric and gas), heat pumps are way ahead. They only require about a third of the energy required by these heaters. This means that using a heat pump can save about 70% in energy costs.
Advantages of heat pumps
Heat pumps are a suitable replacement for conventional water heaters. They provide users with countless benefits, including:
1. They can heat a lot of water at once. There are heat pumps with a capacity of up to 200 liters.
2. Compared to traditional water heaters, they are highly cost-effective because you need less energy to heat the same amount of water.
3. They have a long lifespan. You can use your heat pump for five years without any major failures.
4. They can also act as coolants. Heat pumps tend to cool where they are installed.
5. The heat pump is completely safe.
6. They are easy to install and relatively simple to maintain.
7. The only disadvantage of heat pumps is the functionality of the refrigerant they contain. The heating coils must be adequately protected against corrosion. Also, refrigerant gas can be bad for the environment. It is recommended that you check the environmental impact before starting to use the heat pump.
Solar water heaters
Solar energy has been widely used in the past few years. Today, we have solar cars, lighting systems and now heating systems. Why don't we delve into how solar water heating systems work?
What is a solar water heater?
Solar water heaters use solar energy to heat water. It's so simple. They take the energy distributed by the sun and convert it into heat.
Solar water heating systems are installed in open spaces, where they receive maximum sunlight. Energy from the sun is converted into heat. This thermal energy is then transferred to the water in the holding tank.
Solar water heaters only work without electricity. They also don't have an on/off switch. Should. Use the sun to heat the water continuously throughout the day. This means that the amount of hot water you will have depends on the size of the storage tank.
Types of Solar Water Heaters
1. Flat Plate Collectors (FPC): These systems are made of metal. They tend to have longer lifespans.
2. Evacuated Tube Collectors (ETC): They are mostly made entirely of glass. They are more granular than FPC systems.
Both types of solar heaters may be equipped with pumps. This pump is used to effect the movement of water from the storage tank to the collector.
What type of solar heater should I buy?
Both systems are very useful. Deciding which one to buy comes down to your personal preference.
The ETC system can be said to be fragile. They are also cheaper than FPC systems. They are perfect for cooler regions where temperatures may drop below zero. If you are going to use these systems where the water is very salty, they must be cleaned regularly to avoid salt deposits.
On the other hand, FPC systems are more durable. They are made entirely of metal and can work in harsh conditions. FPC systems are expensive options. If you are using them in cold regions, you must buy antifreeze. Also, where there is salt water, you must use them with heat exchangers to avoid limescale deposits.
How efficient is a solar heater on a rainy day
Many users are often concerned about the efficiency of solar energy systems on rainy days. You don't have to worry about this. Your solar water heater will still work as long as it doesn't rain for more than two days. This is because your average solar system works with diffuse radiation. This diffused radiation remains in the atmosphere even if it rains for a day or two.
If you're still concerned, you can integrate your solar system with an electrical system that kicks in if the cloudy day persists for a long time.
Energy consumption and savings
When the sun is shining, your solar water heater consumes almost no energy. At night, however, it has a traditional geyser element used to heat your water. The total energy consumption of a solar water heater depends on how often you use your hot water. However, you can expect energy savings in the range of 45%-70%.
Maintaining a Solar Hot Water System
Here are some tips to ensure your solar heating system works for you in the long run:
1. If you use an ETC system, you must be extra careful. Be careful when cleaning. Since the glass is fragile, it may also need to be replaced from time to time.
2. You may need to periodically clean the system with acid. This is done to avoid scaling, especially if your water is classified as hard water.
3. If the exterior components of your solar heater are painted, you may need to paint them regularly to avoid corrosion.
4. Occasionally, leaks may occur over time. These leaks can be repaired by a local plumber.
Solar water heaters are a win-win for users. They are very environmentally friendly and can save you thousands of dollars on your utility bills. Likewise, renewable energy appears to be the future of technology. Following this exciting new trend makes great economic sense.
Also, solar water heaters are easy to install. Although, you should probably know that buying and installing new equipment can be very expensive. They are also very durable. Even with regular use, they have a lifespan of more than ten years.
On the other hand, heat pumps are also an amazing innovation. Those that drastically reduce your electricity usage are a huge help. If your goal is to spend less money to heat water, then a heat pump is for you.
There are no two ways. Heat pumps are very expensive. However, they are a cost-effective option that can pay you big dividends over a long period of time.
Finally, both heat pumps and solar water heaters are great alternatives to traditional water heaters. You can't go wrong with either.
