This is in fact due to unstable cold water pressure. The main solution is to install a thermostatic valve or a hot water booster. It is best to install both. The thermostatic valve can automatically adjust the temperature. But there are still times when you feel cold or hot, but they are much less frequent now. The same goes for installing a booster pump, because the pressure difference between hot and cold water is too great. When the cold water changes, the hot water changes significantly. If the hot water pressure increases and the hot and cold water pressure is relatively constant, then when the cold water changes, the hot water change will be small because the pressure difference is not large . You can first install a thermostatic valve, and if this remains unacceptable, install a hot water booster pump. That's it, it will be surevery useful. First of all, there is only a two-story gap between your solar water point and the water point, so the waiting time will not be long, so you don't need to circulation pump. What the after-sales service says is correct. The larger the gap between the water point and the solar water tank, the greater the water outlet pressure, the hot and cold water during use is also related to the stability of hot and cold water pressure. at that time Suggestion: You can cancel the circulating water pump (because you don't know if it is installed correctly) and directly install an automatic booster on the solar hot water outlet pump (it is better to 'use with the original water circulation pump) is available on the market for around 150 yuan each. Once installed, it can basically ensure the stability of hot water pressure and outlet speed of thehot water at all water points on both floors (reduce waiting time). There are also ways to stabilize cold water pressure: try not to share a water pipe with multiple households, use a dedicated pipe (your own dedicated tap water pipe), or try not to have multiple people in your home using intermittent water at the same time. time, or cold water pipes. Also install pressure-boosting equipment in the building or install a water storage tank on the roof to stabilize cold water pressure.
It's relatively simple. There are three ports, one with two ports on one side is connected to cold water and the other is connected to hot water, and the one with only one port is connected. one side is connected to the nozzle.
Yes Note that the thermostatic valve requires a minimum pressure limit for cold water and hot water. You can see it in theproduct manual, or it is better to ask the dealer. . Otherwise, state this clearly in advance when purchasing. If it is not accessible, you can return it if the effect is achieved.
