Heat pumps
Efficient heating, free from oil and gas.
We focus on the two solutions that fit best in most cases: air-to-water heat pumps and heat-pump boilers, both from Midea. Combined with your photovoltaic system for maximum self-consumption.
So arbeiten wir
From oil boiler to heat pump, structured
On-site analysis
We record the available outdoor space and the connection situation. Sizing is based on your previous oil consumption; the building energy certificate (GEAK) serves as the reference.
Incentive & planning
We handle the cantonal incentive application and the detailed planning. The hydraulic balancing is carried out by our partner firm.
Installation
Removal of the old heating, mounting of the new heat pump, hydraulic and electrical connection. Hydraulic balancing and on-site commissioning are carried out by our partner firm.
Handover & incentives
Handover of the system and submission of the incentive confirmation. Ongoing maintenance and remote monitoring are not part of our scope.

Air-to-water and heat-pump boiler: the two paths
Ground-source heat pumps with a borehole are still the most efficient solution. But borehole drilling is expensive, bureaucratic and restricted in many Swiss zones. For most homes air-to-water is therefore the more pragmatic choice: far less overhead at good efficiency. An air-to-water heat pump may also require a permit depending on the municipality.
Air-to-water (small)
6 – 20 kW
The standard for single-family homes, new builds and retrofits. Monobloc outdoor unit, no borehole. Units from Midea.
- Monobloc 400V/3-phase, outdoor installation
- No borehole, no ground probe
- Ideal to combine with PV
Air-to-water (large)
20 – 60 kW
Larger air-to-water systems, often as a cascade of two units, for multi-family homes, small commercial operations and housing estates.
- Cascade operation for part-load efficiency
- Acoustic report incl. cantonal requirements
- Integration with ZEV PV concepts
Heat-pump boiler
Hot water
Replacement for the electric boiler: a heat-pump boiler from Midea produces hot water with significantly less electricity.
- Heat-pump boiler for hot water
- Simple 1:1 replacement of the electric boiler
- Top candidate for PV self-consumption
Häufige Fragen
Heat pumps: your most common questions
Why does Bergler mostly install air-to-water rather than ground-source?
Ground-source with a borehole is more efficient, no question. But borehole drilling quickly adds CHF 20,000 – 40,000 in extra cost, requires permits and is restricted in many Swiss zones. For most homes air-to-water is therefore the more pragmatic choice. If ground-source makes sense in your case, we'll tell you honestly.
Does a heat pump work with radiators?
Often yes. What matters is the heating system as a whole, especially flow temperature and the water volume in the circuit. Whether your existing system is suitable we clarify case by case. Swapping individual radiators usually doesn't solve it.
How high is the incentive?
Varies significantly by canton. Typical for an air-to-water heat pump replacing an oil boiler: CHF 3,500 – 8,000. Plus federal tax deduction (energy-efficiency retrofit) and municipal contributions. We handle all applications.
What does a heat pump cost to run?
For a typical single-family home (approx. 15,000 kWh heat demand): roughly 3,500 – 4,000 kWh of electricity per year, at current tariffs around CHF 1,000 – 1,200. On top of that come the annual maintenance costs. When a PV system runs at the same time, operation is often significantly cheaper through self-consumption.
How well does a heat pump fit with PV and battery?
Well. An air-to-water heat pump uses the solar surplus during the day; with a battery you can catch some of the evening peaks. Typical Bergler setup: PV + battery + air-to-water HP as a full system with a single control. We don't combine an air-to-water HP with a separate heat-pump boiler.
How loud is an air-to-water heat pump?
Modern inverter models run comparatively quietly; the actual values depend on the model and placement. With correct placement the unit is barely noticeable inside. We check compliance with cantonal noise regulations before the quote.
Which manufacturer does Bergler use?
Our heat pumps and heat-pump boilers come from Midea, one of the world's largest HVAC and heat-pump manufacturers. The units deliver a very strong price-performance ratio, and service coverage in Switzerland is solid.
