The reason why the solar water heater can not be heated
The electrical or signal cannot be passed, if it is sunny when water temperature is not up, it is because of the scale of the vacuum tube is too large, cloudy is not much effect. This is the water heater vacuum tube, I hope to help you.
The former can be cleaned, go up and take off the scale, the latter need to be replaced, and the other is because the line and the control device can not be heated
What do you mean, you can't heat it? Is it a home or a business? I'm here to give you a reply. If it's an electric heater, it can't be heated because of the serious scaling of the electric heating pipe or the damage of the electric heating tube
