Instead of letting that heat simply drain away, a heat exchanger transfers it to the incoming mains water, so your boiler or water heater needs less energy to bring it up to temperature.\n\nA typical WWHR system can reduce the energy needed to heat shower water by 40–60%, depending on the flow rate and installation setup. That translates directly into lower utility bills and a smaller carbon footprint for your home or building project.\n\nFor those asking what is waste water heat recovery in practical terms, think of it as a simple, passive technology that works every time someone showers, with no moving parts, minimal maintenance, and no impact on shower performanc","contained","What Is Waste Water Heat Recovery?","uploads\u002Fstorefront\u002Fc4e58ff3-9c34-4a15-9b40-1cd1e45018d6.png",{"id":60,"type":49,"settings":61},"section-1781690214146-1fc96c2",{"width":23,"padding":11,"background":19,"backgroundColor":16},{"id":63,"type":53,"settings":64},"section-1783345097900-pfhg8ba",{"body":65,"width":56,"layout":66,"ctaHref":67,"heading":68,"padding":19,"ctaLabel":69,"imageUrl":16,"imagePath":70,"background":19,"backgroundColor":16},"WWHR relies on a straightforward principle of heat exchange. The system typically consists of a copper or stainless steel coil wrapped around a vertical section of waste pipe. When you shower, warm waste water flows down this pipe while cold mains water runs through the coil in the opposite direction.\n\nBecause heat naturally moves from warmer to cooler surfaces, the thermal energy in the waste water transfers through the pipe wall and into the incoming cold water. This pre-heated water then flows to your shower mixer or hot water cylinder, so the heating system has to do less work to bring it to the desired temperature.\n\nThe efficiency of this process depends on factors such as the length and diameter of the heat exchanger, the flow rate of the shower, and the temperature difference between waste and cold water. In many cases, heat recovery shower systems can recover up to 60% of the heat that would otherwise be lost down the drain.","stacked","\u002Fcommercial-waste-water-heat-recovery-solutions","How WWHR Works: The Science Behind Heat Recovery","View The Full WWHR Range","uploads\u002Fstorefront\u002Fcd674ec1-6114-4e80-b88a-ee171212cfc9.png",{"id":72,"type":49,"settings":73},"section-1781690214147-af1fa2c",{"width":23,"padding":11,"background":19,"backgroundColor":16},{"id":75,"type":76,"settings":77},"section-1781690214147-22942ec","heading",{"text":78,"align":22,"level":45,"width":56,"padding":14,"maxWidth":19,"background":19,"backgroundColor":16},"Key Benefits of Waste Water Heat Recovery",{"id":80,"type":81,"settings":82},"section-1781690214147-3bf209a","multiColumn",{"columns":83,"imageFit":93,"imageSize":94,"columnCount":95},[84,87,90],{"body":85,"icon":16,"heading":86,"imageUrl":16,"imagePath":16,"buttonHref":16,"buttonLabel":16},"By pre-heating cold water with recovered heat, your heating system uses less gas or electricity for each shower.

In residential applications, it is most commonly used in showers in flats, apartments, and ground-floor bathrooms where retrofitting a vertical system is practical. For homeowners looking to improve energy efficiency, adding a WWHR unit alongside a shower upgrade can be a straightforward project.\n\nIn commercial environments such as gyms, hotels, schools, and leisure centres, the consistent high-volume shower usage makes WWHR especially effective. These installations typically use larger heat exchangers, like those in the Power-Pipe range, to maximise recovery across multiple shower outlets.","right","Where WWHR Is Used",{"id":106,"type":49,"settings":107},"section-1781690214147-d887dbd",{"width":23,"padding":11,"background":19,"backgroundColor":16},{"id":109,"type":110,"settings":111},"section-1781690214147-15ee88c","richText",{"html":112,"width":56,"padding":11,"maxWidth":113,"background":114,"backgroundColor":16},"\u003Cp>\u003Cstrong>Installation Considerations\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>Whether you are a \u003Cstrong>Quantity Surveyor\u003C\u002Fstrong>, \u003Cstrong>Contractor buyer\u003C\u002Fstrong>, or \u003Cstrong>Homeowner\u003C\u002Fstrong>, understanding the installation requirements of WWHR is key to selecting the right system.\u003C\u002Fp>\u003Cul>\u003Cli>\u003Cp>\u003Cstrong>Retrofit projects:\u003C\u002Fstrong> For existing bathrooms, the Sanura integrated shower tray is often the simplest option because it does not require access below the floor.
