pattereisiin

Pattereisiin is a Finnish noun form derived from patteri, meaning radiator. It is the illative plural form used to indicate movement into or placement into multiple radiators. The construction is common in technical descriptions of heating systems, installation instructions, and other contexts where heat distribution or routing to several radiators is described.

Grammar and usage: Pattereisiin appears when the action is directed toward more than one radiator. It contrasts with singular illative forms that refer to a single radiator. In Finnish, illative forms convey the idea of “into” or “onto” and are used with verbs of placement, installation, or flow, such as asennetaan (is installed) or ohjataan (is directed).

Contexts and examples: In practical texts about heating installations, pattereihin can occur in sentences like “Laitteet asennettiin pattereihin,” meaning that the devices were installed into the radiators. It is also used in discussions of how heat or components are routed to multiple radiators within a building’s heating network.
