&1. Wilo Electric will recommend a suitable hot circulating water machine model for you based on your actual situation: ,&Indoor forced exhaust machine,
it is recommended to use a mechanical version of circulating water. (Two shower rooms, suitable for mass customers) Reason: The mechanical version has fewer procedures and is simple to operate. Press it before use and has a reset switch. It is useful in winter but not in summer. When hot circulating water is not used, the normal use of the water heater will not be affected.
, & outdoor unit,
If there is a return pipe, it is recommended to use the water flow version
(Advantages: Turn on the hot water faucet to circulate, and turn off the water to stop).
If there is no return pipe, it is best to use a wireless remote control type.
Advantages: Multiple remote controls can be added for operation anytime and anywhere.
The outdoor unit is installed far away and the switch is inconvenient. If there is a return pipe, turning on water is equivalent to a switch anywhere. If you have a remote control, you can control it indoors. The remote control has a two-way signal and you can see the water heater and hot circulating water at the same time. working status.
Usage experience: When you wake up in the morning and want to take a shower, you don’t need to move. Just control the remote control on the bedside and go to the bathroom to take a shower. Turn on and hot water comes out directly. No need to wait.
, & Indoor balancing machine, if there are two or more shower rooms, the circulating water must be installed at a certain distance. It is strongly recommended to use a mechanical plate imported pump circulating water system
The reason is that the balancing machine is originally installed in the bathroom. , it’s not too far from the bedroom, you just need to go there and turn it on before using it, so that both shower rooms and the kitchen can use hot water at the same time.
2. What is the difference if there is a return pipe or not?
It is recommended that those with return pipes use water flow control and fully automatic ones.
, & The water flow means that just turn on the hot water and then turn it off in any place with hot water, and the circulating water will automatically circulate at a speed of one meter in three seconds. After the cycle is completed, turn on any place with hot water. Hot water will come out directly.
Advantages: It is strongly recommended that wall-mounted boiler users use water flow control, because it can set short time control, which means that within a certain period of time, hot water can be used at any time.
, & Fully automatic means temperature control. Generally, bathing centers such as villas or hair salons can choose fully automatic mode. The so-called fully automatic means setting the temperature of the water heater to ℃, setting the circulating water system to ℃, and then There is a temperature control sensor probe connected to the end of the return pipe, so that once the temperature drops below 10°C, it will automatically start. It is started once a day, which is very wasteful. It is recommended that ordinary households do not use this function.
Note: Why can’t the above two functions be used without a return pipe?
If the water flow function does not have a return pipe, sometimes it will start when cold water is turned on. Because the water flow sensor is installed in the pump body of the water control panel, so the water pipe If the water inside fluctuates greatly, it will cause circulating water to work.
Temperature-controlled ones cannot be used, because if there is no return pipe, if the circulating water is frequently started, the cold water in the hot water pipe will be squeezed into the cold water pipe. In this way, when the cold water is turned on, hot water will also come out, so use a computer board. It is best not to debug the computer board by yourself to avoid debugging and setting the temperature control incorrectly.
If there is no return pipe, it is recommended to use a mechanical panel or a remote control panel.
