| solar water heater | Energy saving, environmental protection, low operating cost | Affected greatly by weather, high initial investment | sunny areas |
| Air energy water heater | Energy-saving and efficient, stable operation | High initial cost and takes up a lot of space | Families with high energy saving requirements |
Recommended hot water solution for two- and three-story villas
Based on the characteristics of three-story villas, the following combination options are recommended:
1. Solar + gas water heater combination
Use solar water heaters as the main heat source and gas water heaters as the auxiliary heat source. Priority is given to using solar energy on sunny days, and starting gas water heaters on rainy days or winter. This solution saves energy and ensures the stability of hot water.
2. Air energy water heater + water storage tank
The air-source water heater has high energy efficiency, and when paired with a large-capacity water storage tank, it can meet the multi-point water needs of a three-story villa. Water storage tanks can be installed on the roof or in the basement and deliver hot water through pipes to each floor.
3. Installation of instant electric water heaters in layers
Install independent instant electric water heaters on each floor to avoid energy loss in transporting hot water over long distances. This solution is suitable for areas with low electricity costs and is easy to install and maintain.
3. Plan comparison and selection suggestions
| Plan | initial cost | running cost | Maintenance difficulty | Recommendation index |
|---|---|---|---|---|
| Solar + gas | Middle to high | low | in | ★★★★★ |
| Air energy + water storage tank | high | low | Middle to high | ★★★★ |
| Layered instant electric water heater | in | high | low | ★★★ |
4. Precautions for installation and use
1.Pipe insulation: When transporting hot water over long distances, the pipes must be insulated to reduce heat loss.
