The new tank systems, such as WERIT safety tanks Techno K and E, offer numerous advantages in terms of safety and space savings: they are light-weight, clean and anti-corrosive and can be set up as battery, multi-block and angle systems. Thanks to their compact dimensions they are easy to handle, even in tight areas. A second exterior tank made entirely of plastics allows direct installation in the central heating room and makes the use of an oil pan, additional mason work and triple protective coating absolutely redun-dant. Anyone who installs a WERIT tank will be pleased with the additional space they now have available for other uses.
