At Eco Spares, all WES (now Woodco) biomass boiler parts are 100% genuine OEM products. Each part is sourced directly from the manufacturer or their official distributors and undergoes strict quality checks before shipping. Look for the 'OEM-approved' badge on every product listing for extra assurance—this means your part will fit and function exactly like the original, protecting your boiler's warranty and performance. If you ever need confirmation, our technical support team is happy to verify compatibility or authenticity before you buy.
