A heat pump quote should show more than just the equipment price. The key is whether the solution is complete and suitable for the building: heating output, domestic hot water, dismantling, electrical work, sound insulation, permits, and subsidy assumptions must be clearly stated. Those who only compare the final price often overlook the crucial differences. The comparison becomes most meaningful with two to three complete, identically structured quotes.
The most important points in brief
- Obtaining multiple quotes makes differences in technology, scope and price visible.
- The heating output must be justified and not simply taken over from the old boiler.
- Dismantling, sound insulation and electrical work must be included in every quote.
- Subsidy assumptions should be transparently indicated as an estimate or a confirmed contribution.
- Service, warranty and schedule are part of the comparison.
- The cheapest quote is not automatically the best.

What a good quote should include
| quote item | Why is it important? |
|---|---|
| Heat pump type | determines cost, efficiency and permit |
| Heating output / sizing | prevents under- or oversizing |
| Domestic hot water and buffer tank | crucial for comfort and efficiency |
| Installation and hydraulics | Connection to the existing system |
| Electrical work | own connection, adjustments if necessary |
| Dismantling and disposal | often a major cost block |
| Sound insulation | especially for air-to-water outdoor units |
| Permits / notifications | depending on the type of heat pump, canton, municipality and location |
| Subsidy assumptions | affect the net costs |
| Service, warranty, timeline | Reassurance throughout the service life |

Heating output and sizing
The output of the old oil or gas boiler should not be taken over without verification. Those who are still deciding between the systems will find a comparison of investment, operation and requirements under Heat pump or gas heating. A good quote justifies the heating output in a comprehensible way based on heat demand, building envelope, domestic hot water demand and heat distribution. An oversized heat pump cycles more frequently and operates inefficiently, while an undersized one cannot handle the cold days. The impact of sizing on operation is shown in Electricity consumption of a heat pump.
Domestic hot water, dismantling, electrical work and sound insulation
These items are most often handled differently – and this is exactly where the price differences between two quotes arise:
- Domestic hot water and storage: The size and type of the storage tank affect comfort and efficiency.
- Dismantling and tank disposal: A relevant block when replacing an oil or gas heating system.
- Electrical work: varying effort depending on the house wiring.
- Sound insulation: central for air-to-water systems; location and measures should be specified (see air-to-water heat pump).
Subsidy assumptions and permit
A serious quote shows whether and which subsidies have been taken into account – and whether it is an estimate or a confirmed contribution. It should also be clear who handles applications and permits. Since subsidies are regulated at cantonal level and not guaranteed, this point must be stated transparently. More on this: Heat pump subsidy Switzerland 2026. For borehole heat pumps, drilling permits and geology must also be considered.
Service, warranty and timeline
Over the entire lifespan, not only the purchase price counts, but also the maintenance offer, warranty conditions, response time in case of faults and spare parts availability. A realistic schedule – including delivery times and any permit procedures – also belongs in the comparison.
Information you should have ready
To enable specialist installers to assess your project realistically and prepare comparable quotes, some planning data are helpful. This is not about a form, but about the technically relevant fundamentals:
- Property type: single-family home, apartment building or commercial.
- Ownership status: whether you have decision-making authority.
- Existing heating system: oil, gas, wood/pellets, electric heating or an existing heat pump prior to renovation or replacement.
- Heat distribution: radiators, underfloor heating or mixed.
- Heated living area and number of people in the household: Basis for heating load and domestic hot water.
- Desired timeframe: So that deadlines can be planned realistically.
- Location with address: decisive for sound insulation, drillability and subsidy.
The more complete these details are, the more precise and comparable the quotes will be.

Comparison checklist
- heat pump type and justified heating output
- Manufacturer, model and domestic hot water/buffer tank
- Dismantling, tank disposal and electrical work
- sound insulation and location of the outdoor unit
- Permits and responsibility for them
- Subsidy assumptions (estimate or confirmed)
- Service, warranty and response time
- schedule including delivery and procedures
Typical mistakes when comparing quotes
- Comparing only the total price. The scope of work is what matters.
- Comparing quotes with different scopes. They are only comparable when structured alike.
- Treating the subsidy as confirmed. Assumptions are not a guarantee.
- Ignoring service and warranty. They matter throughout the service life.
- Obtaining too few quotes. Without a comparison, there is no benchmark.
A complete quote combines technical design and location assessment. This includes verifiable noise protection for heat pumps, the calculated sizing of the heat pump, and identifiable measures against typical planning errors with heat pumps.
How many quotes are sensible?
Two to three complete, comparable quotes are generally sufficient to identify differences without unnecessarily complicating the process. More important than the number is that all quotes list the same items. Through waermepumpen-guide.ch, you can reach up to three suitable specialist installers in your region – without having to search individually yourself.
Conclusion
A good quote explains the solution – from the justified heat pump type to dismantling and sound insulation, right through to subsidy assumptions and the schedule. Those who only compare the total price often overlook important differences. With two to three complete quotes, you can make a well-founded decision – and retain the choice of whether and whom to commission.

Frequently asked questions and answers
How many quotes are sensible?
Two to three complete, comparable quotes are generally sensible. It is essential that all list the same items.
What is the most common mistake when comparing?
Only looking at the total price instead of the scope of services. Two quotes with the same final price can be very different.
Should subsidies be included in the quote?
Yes – transparently as an assumption or as a confirmed contribution, specifying who submits the application.
Is the cheapest quote the best one?
Not automatically. A cheap but incomplete or poorly planned solution can be more expensive over the years.
How do I obtain multiple quotes?
Submit your request once via waermepumpen-guide.ch; it will be forwarded to up to three suitable specialist installers in your region.
