Heat pump with "complete financing" — what to check?

5 checks for financing package deal:

1. Real annual raterequest effective rate (BKR-grade); marketing of "0%-rate Warmtefonds" is only for incomes < threshold, else 2-4%
2. Term + monthly7 years high income realistic, 20 years low income; calculate total: monthly × months vs cash-buy minus subsidy
3. Real lenderWarmtefonds is government-financed, but "private partner" can charge 7-12%
4. Subsidies in packageISDE often netted off in quote, but you must FILE ISDE in your name (no intermediary entitled to subsidy)
5. Connection termscan you sell/pay off before end without penalty? Red flags: low monthly, high price (often: "subsidies removed" embedded in price but not later paid out); marketing pressure to sign today; no written summary of financing. For own comparison: use Warmtefonds calculator directly and compare quote.
