How to change heating from series to parallel
With the arrival of winter, the renovation of heating systems has become the focus of attention for many families. In particular, changing the traditional series heating system to a parallel type has become one of the hot topics in the past 10 days. This article will provide you with a detailed analysis of the transformation method of heating from series to parallel in terms of the necessity of transformation, specific steps, precautions, and comparison of relevant data.
1. The difference between series and parallel heating systems
Before retrofitting, you first need to understand the difference between series and parallel heating systems. Here's a comparison of the two:
| Comparative item | series system | Parallel system |
|---|---|---|
| Heating method | Hot water flows through each radiator in turn | Hot water flows through all radiators simultaneously |
| temperature uniformity | The temperature of the end radiator is low | All radiators have uniform temperatures |
| Maintenance convenience | The entire system needs to be shut down during maintenance | A certain radiator can be repaired individually |
| Energy consumption | higher | lower |
2. Necessity of transformation
Although the series system has a simple structure, it has obvious shortcomings: low temperature of the terminal radiator, inconvenient maintenance, and high energy consumption. The parallel system can effectively solve these problems and improve heating efficiency. The following is the statistics of netizens’ demand for transformation in the past 10 days:
| Platform | Amount of related discussions | Popular keywords |
|---|---|---|
| Zhihu | 1200+ | Changing series connection to parallel connection, uneven temperature of radiator |
| 3500+ | Heating renovation, winter heating | |
| Douyin | 5000+ | DIY renovation, heating repair |
3. Specific steps of transformation
1.Preparation: Turn off the heating system, drain the water in the pipes, and prepare the required tools and materials, such as pipes, valves, tees, etc.
2.Remove original pipes: Remove the pipes of the series system one by one, paying attention to retain the interface of the radiator.
3.Install parallel piping: Branch pipes are branched from the main pipe and connected to the water inlet and return port of each radiator to ensure that each radiator has independent water inlet and outlet pipes.
4.Install valve: Install valves on the water inlet and outlet pipes of each radiator to facilitate individual control.
5.test system: Refill water, check for leaks, and test the heating effect of each radiator.
4. Precautions
1.Pipe layout: The pipeline layout of the parallel system is relatively complex. It is recommended to plan the pipeline direction in advance to avoid intersection and entanglement.
2.Valve selection: Choose valves with reliable quality to avoid system leakage due to valve failure.
3.Professional help: If you are not familiar with the modification process, it is recommended to ask professionals to perform the operation to avoid unnecessary losses.
5. Comparison of effects after transformation
The following is a comparison of the heating effect of a home before and after renovation:
| Comparative item | Before transformation (tandem) | After transformation (parallel connection) |
|---|---|---|
| average room temperature | 18℃ | 22℃ |
| Energy consumption | high | 15% reduction |
| Maintenance convenience | Poor | Excellent |
6. Summary
Changing the heating system from series to parallel can not only improve heating efficiency, but also reduce energy consumption and improve maintenance convenience. Although the transformation process is relatively complicated, through reasonable planning and professional operation, the ideal transformation effect can be achieved. If you are facing problems with uneven heating temperatures or excessive energy consumption, you may want to consider retrofitting to enjoy a more comfortable winter heating experience.
