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.

Household tax credit: 35% of the labour share of a company invoice, up to €1,600 per person per year, with a €150 own share (Verohallinto, 10 February 2026). The government has proposed raising this to 40% and €2,100 for 2026–2027, retroactively from 1 January 2026 (HE 113/2026 vp, Eduskunta, 11 June 2026). Parliament has not passed the bill, and the tax administration still writes about it in the conditional (Verohallinto, 16 June 2026).
