Closed and hydraulically controlled




DDLT water heaters are designed to serve one to several close points as would be found in a bathroom. The DDLT 21 and 24 are suitable for hot water supply to a bath or shower but not for simultaneous operation.

Should a shower or bath application be installed, then a 3-phase 400V supply must be provided.

The units are constructed with an impact-resistant white synthetic outer casing and glass-fibre reinforced polyamide heating block. The heater coils are directly immersed in the water so as to ensure rapid heat transfer and minimal scale formation.

Operation is automatically initiated when a tap is opened. The use of a dual safety system, with over-temperature and over-pressure protection (10 bar), provides the hot water installation with maximum safety.

DDLT Water Heaters will work with any type of tap including single lever taps.
