Ascaso 230V Thermoblock with Fittings (1000W) Complete 230V/1000W thermoblock heating element with two 1/8" female BSP fittings for water circulation. The heating filament is wrapped in a 6 mm thick ceramic insulator that circles the center three times, while the internal water tubing (3.5 mm ID) circles the center five times for heat transfer. Gaskets are not included. SPECIFICATIONS 230V, 1000W 2 x 1/8" female BSP fittings for water circulation Ceramic insulator 6 mm thick, 3 wraps around the filament Water tubing 3.5 mm internal diameter, 5 wraps COMPATIBILITY Fits: Ascaso models using this thermoblock design Replaces: Ascaso I.2237 Works with: 2 x I.3096 heat exchanger gaskets (not included) INSTALLATION Technician recommended - involves electrical disconnection and plumbing work on a pressurized water line. PRO TIPS Always install both I.3096 gaskets fresh alongside the new thermoblock - reusing a compressed original gasket on a brand-new block is the most common reason a "new part" leaks right out of the box.
