Published prices across Finland run €13,000–€18,000. The spread is method, not noise: the sources are costing different jobs. €17,000–€18,000 replacing oil heating, demolition included — 2 costed worked examples (Motiva, 2024). €13,100–€13,900 jobs actually paid for — median of 2 verified jobs (urakkadiili.fi, 19 August 2026). €13,000–€16,000 installed — a vendor’s stated range (1komma5.com, 2026). Usually quoted separately: a domestic hot water cylinder, a buffer cylinder, balancing the radiator network, work on the electrical panel and a foundation for the outdoor unit.

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).

The grant is closed. Applications ended on 25 May 2026 at 16.15, the appropriation was spent in full and over 300 applicants received nothing. It used to pay €4,000 / €2,500 depending on the replacement system (Elinvoimakeskus, 1 September 2026). Giving up oil heating altogether carries an elevated credit of 60% of the labour share, up to €3,500 per person, in force until 31 December 2027 (Verohallinto, 10 February 2026).

It is set by the distribution temperature, not by the brand: 2.8 on 30 °C underfloor heating, 2.2 on a 60 °C radiator circuit, and 1.8 for domestic hot water (Ympäristöministeriö, 20 December 2017). That is the running cost difference the emitters make before any brand comparison.
