Henrad radiators are indeed manufactured by the same overarching corporate parent group and share identical manufacturing standards, internal designs, and production facilities with Stelrad. While they are marketed under different brand names tailored to specific regional markets and distribution networks across Europe and the United Kingdom, both product lines are produced by the same leading corporate entity. They utilize the same high-grade steel materials, advanced convection fin configurations, and durable powder-coat paint systems. Consequently, choosing between Henrad and Stelrad typically comes down to regional availability through specific plumbing merchants or installer preferences, as both brands deliver comparable thermal performance and structural quality.
