Generally speaking, solar water heaters cannot be used in small high-rise buildings. The upper floors of residential buildings are public spaces and cannot be used by individual owners to install solar water heaters. There is also a wall-mounted solar water heater that can solve the problem of the installation site, but there is a risk of falling, so it is not recommended. For small, high-rise residences, traditional gas and electric water heaters are more suitable.
Advantages and disadvantages of gas water heaters
Advantages: Gas water heaters are slightly less expensive than electric water heaters, have fast heating rates and relatively stable water temperatures. They are generally smaller in size. and provide hot water. Quantity is not limited, this is ready to heat type, does not require prelong-term heating and can be used at any time, so it is more suitable for families with a large population.
Disadvantages: Gas water heaters must be installed in separate rooms and the installation steps are more cumbersome than those of electric water heaters. Since there is a gas supply, this means that there can be gas leaks, producing harmful gases endangering human health. Additionally, if the kitchen and bathroom are far apart, using a gas water heater can easily slow down the water supply. Additionally, gas water heaters have very high water pressure requirements, which is why their use is not recommended for high-rise buildings.
What should you pay attention to when choosing a water heater
1. Water heater energy
You don't have to worry too much about electricity. water heater, but water heatersgases are very important. The gas on the market is mainly divided into natural gas, liquefied gas and artificial gas. Therefore, before buying, be sure to check which one is used at home. If the water heater you purchase does not have the same air source as your home, it will be very difficult to return or replace it.
2. Number of liters
The amount of hot water per minute when the tap water temperature and the set temperature differ by 25 degrees. If your house has a kitchen and a bathroom, 10 liters or 12 liters is enough. If you have a kitchen and two bathrooms, buy 13 liters or 16 liters. Likewise, you can also choose the number of liters based on the size of the shower head. The average shower head is around 7 liters and the faucet is around 5 litres.
3. Safety performance

The water pipe is too long, the insulation effect is not good, and the water is wasted.
The main concern when installing solar power is that it will cause safety hazards after installation. “There are elevators in high-rise buildings and the main elevator doors are on the roof. If you are allowed to install solar power, if the solar power leaks,This will seriously affect the safety of building owners and cause losses to residents. This is also a big problem. Again, there is not enough roof space for all homeowners to install solar
As for installing wall-mounted solar, from the walls of the building. the building is covered with insulation foam,The bearing capacity is insufficient, and if it is forcibly installed, problems such as falling from high altitude may occur. This is why, for safety reasons, the regulations for high-rise buildings prohibit the installation of solar energy.
