Published prices across Finland run €1,500–€4,500. €1,500–€4,500 installed — a vendor’s stated range (fiksukuluttaja.fi, 2026). Some sources price the labour on its own, which is a different product under the same word: €60–€150 converting one existing block heater post — a marketplace’s stated range (urakkamaailma.fi, 28 August 2026). Usually quoted separately: upgrading the electrical panel, an electrical network survey and load management.
