Stiebel Eltron WPL-A 07 cool 7 kW — Ireland 2026

German pioneer — 50+ years of heat pump heritage with integrated summer cooling

Stiebel Eltron installed the first heat pump in Germany in 1974. The cool variant provides active cooling in summer through underfloor circuits. R-290 (propane) refrigerant has a GWP of just 3. Smart Grid Ready allows the heat pump to prioritise cheap night-rate electricity automatically.

7 kW SCOP 4.72 45 dB(A) Max 65°C R-290 (Propane) SEAI grant up to €12,500

Key highlights
🌡️
Heat and cool — one system
The cool variant reverses the cycle for passive cooling in summer via underfloor circuits. As Irish summers warm, this dual function is increasingly valued — no separate air conditioning unit required
🌿
R-290 — GWP of 3
Propane refrigerant has a Global Warming Potential 225× lower than R-32 — and unlike synthetic refrigerants, it is not subject to ongoing F-Gas price increases and phase-downs
Smart Grid Ready
Automatically adjusts operation timing to align with cheap grid electricity — Night Saver and Smart Export tariffs are automatically optimised, reducing annual running costs

🏠 Suitable for

New buildDetached homesUnderfloor heatingCooling-capablePremium
Compatibility note: Yes — up to 65°C + passive cooling via floor circuits in summer. A SEAI-registered heat pump installer will complete a heat loss assessment and radiator compatibility check before installation — this is required as part of the grant process.

✅ What we like

  • Heating and cooling in one unit — summer cooling through underfloor circuits
  • R-290 (propane) refrigerant — GWP of just 3, the most climate-friendly option
  • 45 dBA — very quiet outdoor unit
  • Smart Grid Ready — automatically prioritises cheap night-rate electricity
  • Stiebel Eltron — first heat pump manufacturer in Germany (1974)
  • SEAI grant eligible — up to €12,500 (houses, fossil fuel switchers, from 3 Feb 2026)

⚠️ Worth knowing

  • Cooling only works with underfloor circuits — not with radiators
  • R-290 requires certified F-Gas engineer for service — fewer available in Ireland
  • Premium pricing at ~€7,400 supply
  • Operates to −20°C vs −25°C for some rivals

💧 Compatible hot water cylinders

The WPL-A 07 cool 7 kW requires a separately purchased hot water cylinder with a large primary coil (minimum 2.5 m²) to work efficiently at heat pump flow temperatures of 45–55°C. These cylinders are confirmed compatible with Stiebel Eltron heat pumps. Browse all cylinders →

☀️ Pair with solar panels — maximise your SEAI grants in Ireland

A heat pump and solar panels are the most powerful renewable combination available to Irish homeowners today. Your Stiebel Eltron heat pump runs entirely on electricity — solar generates that electricity from your roof at zero cost. Both qualify for substantial SEAI grants. See the full Solar Panel Directory for all models available in Ireland.

💡 Apply BEFORE installation begins. Both the Heat Pump and Solar PV grants require a SEAI Letter of Offer before any contractor starts work. You can apply for both in the same process — ask your installer to coordinate a combined application. Also note: 9% VAT applies to heat pump supply and installation (reduced from 23% since 1 Jan 2025).
🌡️ Why a heat pump and solar are the perfect pair: A heat pump runs entirely on electricity — and a solar system generates free electricity from your roof. A typical 4kWp solar system generates ~3,400–3,800 kWh/year. Your Stiebel Eltron WPL-A 07 cool 7 kW uses ~3,000–5,000 kWh/year for heating and hot water. With both installed, your solar covers a large portion of your heat pump's electricity use — at zero cost. The combination is the highest-savings renewable upgrade available to Irish homeowners today.
