Key highlights
👁️
3D i-See Sensor
Infrared sensor detects the location and temperature of occupants and automatically adjusts airflow direction — heating toward people in winter, away from people in summer
🔇
22 dBA indoors — whisper quiet
At 22 dBA the MSZ-EF is quieter than a whisper in a library. In a bedroom or home office where quiet matters, this is a significant advantage
📐
219mm depth — ultra-slim profile
The thinnest full-performance unit in this directory. At 219mm deep, the wall-mounted unit barely protrudes — important in smaller Irish apartments where space is at a premium
🏠 Suitable for
ApartmentsOpen-plan livingOfficeExtensionSupplement heating
Compatibility note: N/A — air-to-air system only. 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
- 3D i-See Sensor — automatically detects and directs warmth toward occupants
- 22 dBA indoors — barely audible during normal room sounds
- COP 4.90 for heating — excellent efficiency
- 5 kW capacity — suits open-plan living spaces up to 60m²
- Ultra-slim 219mm depth indoor unit
⚠️ Worth knowing
- No SEAI Central Heating Upgrade component
- Air-to-air only — no connection to radiators or underfloor heating
- Higher price than Daikin Emura 3 for the same room coverage

🔋 Pair with battery storage — run your heat pump on solar
The most cost-effective way to run a heat pump in Ireland: pair with solar panels and a home battery. Solar generates free electricity during the day; the battery stores surplus for evening and overnight heat pump operation — reducing your annual electricity bill by 70–85%. Browse all batteries →

☀️ 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 Mitsubishi Electric 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.

How the solar grant works alongside your heat pump grant:

Heat Pump Equipment Grant (all qualifying homes)€6,500
Central Heating Upgrade Grant (if needed)+ €2,000
Renewable Heat Bonus (switching from oil/gas)+ €4,000
EV Home Charger Grant (SEAI)+ €300
Maximum total combined grant€9,600
💡 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 Mitsubishi Electric MSZ-EF50VGK 5 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.
