IP-19 · Hydronic distribution network
Creating a heating network, for example when replacing electric radiators
Separate measure
Connection to an anergy network: M-05 and M-06 amounts reduced by 50%. The subsidised output is capped at 50 W per m² of energy reference area before the work.
Worked example
A 10 kW house, calculated on the scale.
Fictitious example: a single-family home heated with oil, whose thermal study sets the need at 10 kW.
- With an air-to-water heat pump (M-05)
- CHF 5,000
- With a geothermal heat pump (M-06)
- CHF 20,000
- Difference in favour of geothermal
- CHF 15,000
Any municipal grants and the tax deduction come on top of these amounts. Geothermal costs more to buy: see the prices on our geothermal page before comparing.
Conditions
The conditions to meet before filing.

A CECB® for buildings from before 2000
The envelope must be rated A to E, or A to C above 1,000 m altitude for an air-to-water heat pump. The CECB® is updated after the work.
A certified installation
Up to 15 kW, the heat pump is installed to the heat pump system module standard. Above that, a SwissEnergy performance guarantee and a quality label. For geothermal, the driller must hold the GSP label.

Frequently asked questions
Your questions on grants in Vaud.
How much is the Vaud grant for a heat pump in 2026?
+
CHF 5,000 for an air-to-water heat pump in a single-family home (M-05), CHF 20,000 for a geothermal or water-to-water heat pump in a single-family home (M-06). For other buildings, M-05 pays CHF 400 per kW above 15 kW and M-06 pays CHF 4,000 + CHF 800 per kW above 20 kW.
Must the application be filed before the work?
+
Yes. The application must be approved before any order, delivery or start of work. Equipment delivered on site before the grant decision disqualifies the application.
Is a new building eligible?
+
No. M-05 and M-06 fund the replacement of oil, natural gas or fixed electric resistance heating in an existing building.
My building dates from before 2000: what else is required?
+
A CECB® with an envelope rated A to E, or A to C above 1,000 m altitude for an air-to-water heat pump. If the envelope is rated F or G, insulation is needed before the application can be filed.
Can the cantonal grant be combined with a municipal grant?
+
Yes. Several Vaud municipalities pay their own grants, with amounts and budgets that change from one year to the next. Check with your municipality's energy department before signing.
Is the remaining cost tax-deductible?
+
Yes, the net investment after grants is deductible from taxable income as an energy-saving investment. Your accountant can tell you which tax year to attach it to.
