As part of Vaillant’s latest ecoTEC Plus range, it features a refined internal layout that provides easy access to key components, making installation, servicing, and maintenance quicker and more efficient.\n\nThis updated model includes a sleek semi-touch interface, giving both installers and homeowners a smooth and intuitive experience. The guided commissioning wizard simplifies the setup process, while the clear display and easy navigation make everyday use straightforward. With its familiar footprint, pipe connections, and flue positioning, the ecoTEC Plus 836 is also ideal for simple, like-for-like replacements.\n\nPerformance is driven by advanced Vaillant technology. IoniDETECT continuously monitors gas combustion, allowing the boiler to operate across a wide modulation range of up to 1:10. This ensures the system only uses the energy it needs, improving efficiency and helping to reduce running costs. linBUS technology further enhances performance by providing accurate readings of flow rate and pressure via the internal pump.\n\nDesigned with flexibility and future-proofing in mind, the ecoTEC Plus 836 supports automatic LPG conversion on most outputs, completed quickly through the interface without requiring additional parts. It is also hydrogen-ready, meaning it can safely operate with up to a 20% hydrogen blend, helping prepare your home for future energy changes.\n\nFully compatible with Vaillant’s range of controls, flues, boiler protection kits, and renewable technologies, this combi boiler can be tailored to suit a wide variety of systems. It is also smart home ready, working with the myVAILLANT connect internet gateway for app-based control and remote access (additional equipment may be required).\n\n\u003ch3\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\n\nRefined internal layout for easier installation and servicing\n\nIntuitive semi-touch interface with guided commissioning wizard\n\nIoniDETECT technology for intelligent combustion monitoring\n\nWide modulation range (up to 1:10) for improved efficiency\n\nlinBUS technology for enhanced system accuracy and performance\n\nAutomatic LPG conversion (on most outputs) with no additional parts required\n\nHydrogen-ready for up to 20% hydrogen blend\n\nSmart home ready with myVAILLANT connect (additional equipment required)\n\nCompatible with Vaillant controls, flues, and accessories\n\nFamiliar footprint for easy replacement installations\n\nUp to 10-year warranty available with Vaillant Advance Installer\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\nProduct Type: Gas Combi Boiler\n\nModel: ecoTEC Plus 836\n\nGTIN: 4024074906712\n\nHeight: 720 mm\n\nWidth: 440 mm\n\nDepth: 352 mm\n\nWeight (Net): 37.4 kg\n\nGross Weight: 40.5 kg\n\nWarranty: 5 years (extendable to 10 years with Vaillant Advance Installer)\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eIs the ecoTEC Plus 836 suitable for homes with high hot water demand?\u003c\/h4\u003e\n\nYes, this model is designed for larger households or properties with higher hot water usage, providing strong and consistent performance.\n\n\u003ch4\u003eCan this boiler be connected to smart controls?\u003c\/h4\u003e\n\nYes, it is smart home ready and can be paired with the myVAILLANT connect gateway, allowing remote control via an app when used with compatible systems.\n\n\u003ch4\u003eWhat makes this boiler energy efficient?\u003c\/h4\u003e\n\nThe combination of IoniDETECT technology and a wide modulation range allows the boiler to adapt to demand, reducing energy waste and improving overall efficiency.","brand":"Vaillant","offers":[{"title":"Default Title","offer_id":52979127681366,"sku":"148489","price":1776.7,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/vaillant-ecotec-plus-836-combi-boiler-6394235.jpg?v=1775036132","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/vaillant-ecotec-plus-836-combi-boiler","provider":"JJ Building Materials","version":"1.0","type":"link"}
