It uses the flow of water to generate electrical energy for the appliance ignition or control system, without batteries in the hydrogenerator itself.<\/p>\n<p>It comes with an O-ring and a U-shaped metal clip. The model is <strong>WGKA-A-D-B (A)<\/strong>. Before buying, check the reference of the fitted part and the dimensions and connections of your water heater.<\/p>\n<p><\/div><\/div><\/div><\/div><\/div><\/div><!-- Row Backgrounds --><div class=\"upb_color\" data-bg-override=\"0\" data-bg-color=\"#f2f2f2\" data-fadeout=\"\" data-fadeout-percentage=\"30\" data-parallax-content=\"\" data-parallax-content-sense=\"30\" data-row-effect-mobile-disable=\"true\" data-img-parallax-mobile-disable=\"true\" data-rtl=\"false\"  data-custom-vc-row=\"\"  data-vc=\"9.0.1\"  data-is_old_vc=\"\"  data-theme-support=\"\"   data-overlay=\"false\" data-overlay-color=\"\" data-overlay-pattern=\"\" data-overlay-pattern-opacity=\"\" data-overlay-pattern-size=\"\"    ><\/div><div class=\"vc_row wpb_row vc_row-fluid\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h2>Gas water heater hydrogenerator: battery-free operation<\/h2>\n<p>When water passes through the component, the flow drives an internal turbine that converts this movement into electrical energy. This energy is used in the ignition or control system of the compatible heater. The hydrogenerator does not heat the water directly; that is the function of the gas appliance.<\/p>\n<p>An arrow on the housing indicates the flow direction. The red and black cable ends in a two-pin connector, so compare both the hydraulic and electrical connections with those of the part being replaced.<\/p>\n<h2>Compatibility with Bosch and Junkers<\/h2>\n<p>This GOLDMAN SERVICE replacement fits selected Bosch and Junkers water heaters; it is not an original part from those brands. Compatibility depends on the heater model and version. External appearance alone cannot confirm suitability.<\/p>\n<p>To select the correct hydrogenerator, check the following details:<\/p>\n<ul>\n<li>Water heater model and version.<\/li>\n<li>Reference of the fitted component.<\/li>\n<li>Dimensions and position of hydraulic connections.<\/li>\n<li>Two-pin electrical connector type and cable length.<\/li>\n<li>O-ring and U-clip fastening system.<\/li>\n<\/ul>\n<p>If you cannot confirm compatibility, consult your installer or <a href=\"https:\/\/goldmanservice.com\/en\/contacto\/\">contact GOLDMAN SERVICE<\/a> before ordering.<\/p>\n<h2>HDJ-X hydrogenerator technical specifications<\/h2>\n<table class=\"shop_attributes\">\n<tbody>\n<tr>\n<th scope=\"row\">Brand<\/th>\n<td>GOLDMAN SERVICE<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Reference<\/th>\n<td>HDJ-X<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Model<\/th>\n<td>WGKA-A-D-B (A)<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">SKU<\/th>\n<td>26008<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">UPC \/ GTIN-12<\/th>\n<td>199874184364<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Intended use<\/th>\n<td>Ignition or control system of compatible gas water heaters<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Electrical generation<\/th>\n<td>Powered by water flow; no batteries in the hydrogenerator<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Body dimensions<\/th>\n<td>76 \u00d7 49 \u00d7 63 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Product weight<\/th>\n<td>120 g<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Cable length<\/th>\n<td>100 \u00b1 5 mm<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Connector<\/th>\n<td>2 pins; red and black cable<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Housing<\/th>\n<td>PA-30GF<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Screws<\/th>\n<td>SUS302 stainless steel<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Retaining clip<\/th>\n<td>SUS304 stainless steel<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Colour<\/th>\n<td>Grey<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Package contents<\/h2>\n<ul>\n<li>1 GOLDMAN SERVICE HDJ-X hydrogenerator.<\/li>\n<li>1 O-ring.<\/li>\n<li>1 U-shaped metal retaining clip.<\/li>\n<\/ul>\n<p>The package does not include pipes, bushings, fittings or additional adapters.<\/p>\n<h2>Installation and checks<\/h2>\n<p>Installation and checks must be carried out by qualified personnel.

Do not install a component with a damaged housing, cable, connector, seal or clip.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Does it fit every Bosch or Junkers water heater?<\/h3>\n<p>No. It fits selected models and versions. Compare the part reference, dimensions and connections with the fitted component before buying.<\/p>\n<h3>Does the hydrogenerator need batteries?<\/h3>\n<p>No. It generates electrical energy from the water flow. This describes the component itself, not the requirements of other systems that may be fitted in the water heater.<\/p>\n<h3>Are the seal and retaining clip included?<\/h3>\n<p>Yes. It comes with an O-ring and a U-shaped metal clip, in addition to the hydrogenerator.<\/p>\n<h3>Is it an original Bosch or Junkers spare part?<\/h3>\n<p>It is a compatible replacement from GOLDMAN SERVICE. Bosch and Junkers are named to identify compatibility.<\/p>\n<h2>Documentation and support<\/h2>\n<p><a href=\"https:\/\/goldmanservice.com\/wp-content\/uploads\/2026\/08\/Hidrogenerador-GPSR_Multilingue.pdf\" target=\"_blank\" rel=\"noopener\">Download HDJ-X hydrogenerator safety information (multilingual PDF)<\/a>.<\/p>\n<p>See also our <a href=\"https:\/\/goldmanservice.com\/en\/recambios\/\">catering and HVAC spare parts section<\/a>.
