As shown in the figure below, there is a vent on the upper inlet pipe and a vent on the lower return pipe. If you can't find it, touch the hot one is the water inlet pipe, and the cold one is the return pipe.
How to deflate floor heating - the first step.
Put the gas into the water pipe first. First of all, connect the water pipe, and pay attention to someone to take care of it when there is gas deflated. This is because the deflated hose may run.
Then gently open the valve with pliers. Prepare a towel to wrap around the valve, as water will spill out of the valve during deflation and prevent water from running around.
How to vent floor heating - the second step.
Put the gas back into the water pipe. At this time, you need to close the main valve of the return water main first, which is the long handle, which will automatically close when it turns 90 degrees. The deflation process is the same as the water intake, except that the pipe needs to be connected to the deflation valve below.
Put a single water pipe in each house one by one, generally 3-4 per household. The specific operation is to close the main return valve, and close the valves of each single pipe, leaving only one of them to be the return water, and so on for each single pipe.
How to deflate floor heating - the third step.
The third step is to see under what circumstances the gas is successfully deflated, mainly to observe that there is no sewage and gas spewing out of the floor heating pipe. After reaching a basic stable state, finally open all the water flow valves, including the main return pipe, each single pipe. Pay attention to close the two air release valves tightly, with pliers, but not too hard, otherwise it is easy to cause damage to the valve.
If there is a problem with water discharge, be sure to close the main valve of the main inlet pipe immediately and cut off the water source immediately.
It has to do with the temperature of the water, the heating and the floor heating. >>>More
If the bathroom heating pipe is not connected to the heating, you need to consider whether it will be connected in the future, if it will not be connected in the future, then cut it off, if it is a pun, the plug will be blocked! If it's a single tube, string the tubes together! That's it.
Generally, the toilet needs to be installed. For which is more suitable for home use, floor heating and radiators must be more suitable. >>>More
Hello, from the aspect of what you said, there are the following factors that affect whether the floor heating return water of your home is not hot: 1. The laid pipe is too long, the water flows to the end only the temperature of warm water, there is no hot water temperature, and there is a temperature difference of about 10 degrees between the water inlet and the return water. (If this is the case, it is recommended that you add a circulating sail fiber pump) 2. There is dirt in the pipe laid in your home that blocks the water pipe, so that the water temperature is returned to the cold 3, and the filter screen is blocked, which will also lead to this situation.
It's certainly not reasonable, it's not right for you to do that, but it won't be a penalty.
