Electric heater for a solar water heater
The utility model relates to the technical field of solar water heaters, especially electric heater is proposed for a solar water heater.
Solar water heaters, mainly through the absorption of solar radiation to heat domestic water, but in rainy weather insufficient solar radiation intensity, the solar water heater can not produce enough or sufficiently high temperature hot water, in order to compensate for the lack of solar water heaters, solar water heater installation of electric heaters, the use of such technology becomes more widespread, the inventors have found that in practice: electric prior art provides plus
Heat the following problems:
1, electric heater different solar water heater manufacturers use different specifications, models of heating pipes, since the dry, when using scaling and other reasons, electric tube easily damaged, once the electric heating tube is damaged, due to the inconsistency of standard models, such replace the heating tube, maintenance inconvenient.
2, the prior art to provide an electric heater heating tube is still in the water temperature is high enough, or under the water tank condition, the situation is a long dry heating pipe, so that waste of energy, but also caused by dry out high-temperature fire and other accidents.
3, the prior art does not have to provide an electric heater or earth leakage protection features, security issues exist during use.
Utility Model Content
The utility model is intended for the above-mentioned drawbacks of the prior art provides an electric heater for a solar water heater to provide a standard interface for easy installation and replacement, and leakage power
