EAN: 4062321025649 - manufacturer-number: TR1500TO5T - Boiler electric Energy efficiency class A, Energy efficiency class spectrum A+ to F, Tank volume 5l, Nominal power 2,2kW, Design form Built-under, Max. allowable operating pressure 0bar, Nominal inner diameter, cold tap water 3/8 inch (10), Water heating energy efficiency (Nwh) 37%, Capacity profile XXSAttention! Application notice:This item is a pressureless device (maximum permissible operating pressure = 0 bar). It must only be used with pressureless fittings (low-pressure fittings).Please note the difference between high-pressure and low-pressure fittings. The high-pressure fitting mixes the water inside the fitting. The low-pressure fitting is connected to a water tank (boiler) and has 3 connections.
