Gas vs Infrared Heating in Switzerland: A Full Cost Breakdown for 2025

The most common objection to electric infrared heating is simple: electricity costs more than gas per kilowatt-hour. In Switzerland in 2025, residential electricity costs approximately CHF 0.28/kWh, while natural gas costs approximately CHF 0.12–0.15/kWh. That's a 2:1 price disadvantage for electricity before any other factor is considered.

But that 2:1 ratio is only part of the story, because framing this as a straight substitution misses how infrared is actually used. SunWave Ceramica panels are zone heaters — they warm specific rooms when you're in them, on top of (or instead of, room-by-room) your existing heating. The honest comparison isn't "120 m² of gas vs. 120 m² of infrared" — it's what it actually costs to run a panel, and where that cost fits against your gas bill.

This article uses real Swiss energy prices to build a transparent cost model for adding infrared panels — and shows where the genuine savings come from.

The Assumptions

These figures describe what it costs to run an infrared zone-heating system — not what it costs to replace a gas heating system outright. They also exclude Switzerland's CO₂ levy on gas, which is scheduled to rise (see below).

Running Cost: What an Infrared Panel Actually Costs to Operate

Scaled up to an 8-panel system — enough to cover several frequently used rooms — that's roughly CHF 1,000–1,400 per year on grid electricity, or CHF 400–700 per year with 40–60% solar self-consumption. These figures already reflect the 2:1 price disadvantage of electricity (CHF 0.28/kWh) over gas (CHF 0.13/kWh) — the saving doesn't come from infrared being "more efficient" per kWh, but from heating only the rooms and hours you actually need.

Where Infrared Can Reduce Your Gas Bill

Infrared panels don't replace a gas boiler — but used well, they can reduce how much it runs. If you heat the rooms you're actually using with infrared and lower your central heating thermostat by 1–2°C for the rest of the home, the resulting drop in gas consumption can offset some or all of the infrared running cost. A common rule of thumb is roughly 5–10% lower heating energy use per °C of setback, depending on insulation.

The exact saving depends on your building's insulation, room layout, and how consistently the setback is applied — which is why we calculate this per building rather than quoting a single figure for "Switzerland."

The Payback Period

Infrared panels aren't typically a "payback" investment in the efficiency-upgrade sense — there's no boiler being replaced, so there's no large saving to recoup the cost against. Their value is comfort in specific rooms — a cold home office, a north-facing bedroom, a chilly bathroom — at a running cost of CHF 22–34 per panel per month.

Where the economics get genuinely favourable is solar. Self-consuming solar PV through infrared panels during the day brings the running cost down to CHF 9–20 per panel per month, and an 8-panel system (CHF 4,720, installed) typically costs less than a single year of a gas boiler's combined maintenance and replacement reserve.

What's Actually Been Independently Tested

SunWave Ceramica panels have been independently tested by three laboratories. TU Dresden (DIN EN IEC 60675-3) confirmed genuine infrared radiation characteristics. Fraunhofer WKI (MAIC-2022-2428) measured total VOC emissions of just 0.043 mg/m³ — far below regulatory limits, with no carcinogenic compounds detected, including formaldehyde, benzene, and toluene. Labor S.A. (EN 60335-2-30) confirmed the panel's electrical safety: a surface temperature rise of 71.2 K stayed within the 80 K limit, and leakage current measured 0.1 mA against a 0.25 mA limit, confirming the integrity of the Class II double-insulated construction.

These tests confirm what the panel is — genuine infrared, clean, and electrically safe. They're not energy-savings claims, and we don't dress them up as any. The cost figures in this article come from the panel's rated power and typical use, not from a study of any single building's heating bill.

The CO₂ Levy Factor

Switzerland's CO₂ levy on fossil fuels is legislated to increase progressively. The current levy (2025) adds approximately CHF 0.02–0.03 per kWh to gas costs. Future levy rates are expected to rise significantly as Switzerland pursues its net-zero commitments. This means any gas consumption you avoid by lowering your thermostat in infrared-heated rooms becomes more valuable over time — CHF 0.13/kWh is a conservative floor for gas, not a long-term forecast.

Getting an Accurate Quote for Your Space

The figures above are based on a single 650 W panel and an 8-panel system as a working example. The actual panel count and capital cost for your space depend on room size, ceiling height, insulation level, and window area. We calculate this precisely for every enquiry.
