Tank heaters mounted under the sink are modern and ergonomic devices for quick water heating – an optimal solution for systems with one intake point of hot water (OW-5/10/15). Pressure versions can supply several close to each other intake points. Installation directly at the water intake point reduces heat losses associated with the transmission of hot water. They are used most often in small gastronomy, cabin houses, kitchens, bathrooms and toilets as well as in cosmetics and hairdressers studios.
In non-pressure versions: 5.1 / 10.1, offered with a water battery, are applied plastic tanks, polystyrene insulation and 2.2 kW heaters. The pressure series E10 and E15 are equipped with a safety valve in standard, they have an enamelled tank with a magnesium anode and a 2 kW heater. The except is E5 series which have the power of 1.5 kW.
Pressure water heaters OW-E 5 and OW-E 15 with a capacity of 5 and 15 litres, made of high-quality steel, protected against corrosion with ceramic enamel and protective magnesium anode. The devices are equipped with electric heating elements with a power of 1.5 kW (OW-E 5) and 2.0 kW (OW-E 15). They are equipped with thermoregulator enabling regulation of the domestic hot water temperature in a range of 30-80 ° C and an automatic thermal switch-off protecting the tank against overheating and malfunction.
