Broad incumbents

• Vaillant Group: German heating incumbent (Vaillant, Saunier Duval, Bulex brands) producing buffer cylinders and DHW tanks (uniSTOR/Vitocell-class products) for installers. Direct overlap in residential buffer storage but Vaillant bundles storage with its boilers/heat pumps.
• Stiebel Eltron: German hot-water and heating specialist with extensive DHW tank and buffer storage ranges (SBB, SB, SBP series). Direct competitor in residential and small-commercial buffer/DHW storage.
• Viessmann (now Carrier): Major German heating-systems manufacturer offering complete boiler, heat-pump, and integrated thermal-storage tank lines (e.g., Vitocell). Overlaps directly with Juratherm across residential and commercial buffer/DHW tanks, but operates at vastly larger scale as a full systems OEM.
• Bosch Thermotechnology (Buderus): Buderus and Bosch brands produce Logalux buffer and DHW storage tanks for residential and commercial heating. Highly comparable product category with deep installer relationships across Germany.
• Elco (now part of Ariston Group): European heating and hot-water solutions manufacturer offering buffer and DHW storage tanks alongside burner and heat-pump systems. Comparable product category with broader systems portfolio.
• Kingspan (Hot Water Cylinders / hotwatercylinders.eu): Kingspan's hot-water cylinder division manufactures stainless-steel and enameled DHW/buffer cylinders across Europe. Comparable product mix to Juratherm's stainless-steel and enameled SKUs, sold through installer channels.

Direct peers

• Roth Werke: German manufacturer of heating, solar, and storage systems, including the Heliostar buffer/DHW tank family. Direct overlap with Juratherm in residential and small-commercial thermal storage for solar and heat-pump integration.
• Reflex Winkelmann: Specialist German manufacturer of heating-side buffer and DHW storage tanks (Reflex Storatherm line) plus expansion vessels. Closest pure-play peer to Juratherm with overlapping product positioning toward installers.
• Tuxhorn: German heating-system components maker (fresh-water stations, heating-circuit stations) that is Juratherm's existing joint-development partner on the PFW/PFWR multifunctional storage line. Highly comparable product overlap and channel.
• Flamco (Aalberts Hydronic Flow Control): European manufacturer of heating-side components including buffer storage tanks, expansion vessels, and air/dirt separation. Direct overlap in commercial and residential buffer storage with established German/Nordic installer distribution.
