Mitsubishi Ecodan Review: Prices & Best Models for Irish Homes
The Mitsubishi Ecodan is one of the most installed air to water heat pumps in Ireland, and it ranks #2 on our best heat pumps in Ireland list. Here's our independent review: the specs that matter, which Ecodan model to ask for, what it costs installed, SEAI grant eligibility, and how it compares to Daikin, its closest rival for Irish installer mindshare.
Quick Answer
The Mitsubishi Ecodan is an excellent air to water heat pump for Irish homes, and our pick for larger houses and cold-weather performance. It carries a SCOP of around 4.4, keeps working in temperatures down to −25°C, and the FTC controller is consistently praised by installers. Expect €11,500–€15,500 installed before the SEAI grant of up to €12,500. Ecodan models are on the SEAI approved product list, so the grant applies in full. It typically prices slightly above the equivalent Daikin, and for most homes the newer Ecodan R290 range is the model to ask for.
Who Are Mitsubishi Electric?
Mitsubishi Electric is a Japanese engineering giant, and Ecodan is its dedicated air to water heat pump brand, sold in Europe for well over a decade. In Ireland, Mitsubishi Electric has its own operation in Dublin, and Ecodan units have been going into Irish new builds and retrofits for years, so the local installer pool that knows the product inside out is one of the largest of any brand.
Two things come up again and again when installers talk about the Ecodan: cold-weather performance (the units are rated to keep heating down to −25°C, far beyond anything an Irish winter will throw at them) and the FTC flow temperature controller, which installers praise for its setup wizard, room temperature control, and built-in energy monitoring. The trade-off: an Ecodan typically comes in slightly more expensive than the equivalent Daikin.

Which Mitsubishi Ecodan Model Is Best?
“Ecodan” is a range, not a single unit, and the right model depends on your house. These are the three lines you'll see quoted in Ireland:
Ecodan R290: best for most homes
The newest range, available in 5, 6, 8.5, 10 and 12 kW sizes. It runs on R290 (propane), a natural refrigerant that EU F-gas rules favour, and reaches flow temperatures up to 75°C (boiler territory), so more retrofits keep their existing radiators. Rated to operate down to −25°C. If you're getting quotes today, this is the model to ask for.
Ecodan Ultra Quiet R32: the proven workhorse
The R32 monobloc range (including the “Ultra Quiet” models) is what most Irish Ecodan installers have fitted for years, and the low-noise design is a genuine strength where the outdoor unit sits near a bedroom window or a neighbour's boundary. Still a solid buy where an installer quotes it keenly, but R32 is an older-generation refrigerant than R290.
Ecodan Hydrodan: apartments only
A water-to-water unit designed for new-build apartment blocks with a shared ambient heat loop, covering roughly 1.1–7.5 kW per apartment. You'll see it in Irish trade press, but it's a developer product, not something to quote for a standard house.
Our pick: the Ecodan R290 for almost every Irish home, with future-proof refrigerant, the highest flow temperatures in the range, and the same FTC controls. Don't guess the kW size yourself: the SEAI process requires a heat loss survey, and that survey (not the brochure) decides whether you need the 6, 8.5 or 10 kW unit.
Mitsubishi Ecodan Specifications
Figures below are for the current Ecodan R290 monobloc range, which is what Irish installers now quote for new systems. All Ecodan models pair with the FTC flow temperature controller and connect to MELCloud for app control and energy monitoring.

Why the −25°C rating matters
Every heat pump loses output as the temperature drops; the question is how gracefully. The Ecodan is rated to keep operating at −25°C and, on the R290 range, to hold high flow temperatures deep into sub-zero weather. For exposed or inland sites that get proper cold snaps, that headroom is why we rate it the cold-weather pick.
Why installers rate the FTC controller
The FTC7 is the brains of the system: a step-by-step setup wizard, intelligent room temperature control, built-in energy monitoring showing what the pump consumed and produced, and smart-grid readiness. A heat pump is only as efficient as its commissioning, and a controller installers actually like configuring tends to mean better-running systems.
Mitsubishi Ecodan Prices in Ireland
Typical quotes for a fully installed Ecodan air to water system in Ireland run €11,500–€15,500 before the grant. As a rough guide from quotes we've seen: a standard three-bed semi with straightforward pipework lands around the lower end, while larger or four-bed-plus homes needing a bigger unit, a new cylinder, or radiator upgrades push towards the upper end. That's slightly dearer than an equivalent Daikin system, which is the price of the cold-weather spec and the warranty.
Ecodan models are on the SEAI approved product list, so the full grant of up to €12,500 (from 3 February 2026) applies when an SEAI-registered installer fits it in a home built before 2021. That's €6,500 for the heat pump itself, €2,000 towards heating system upgrades, and a €4,000 renewable heat bonus.

Mitsubishi Ecodan vs Daikin Altherma 3: Which Is Better for Ireland?
This is the most common head-to-head in Irish heat pump quotes, the two brands installers reach for first:
| Feature | Mitsubishi Ecodan | Daikin Altherma 3 |
|---|---|---|
| SCOP | ~4.4 | ~4.6 |
| Cold-weather rating | Operates to −25°C | Strong, but the Ecodan is the cold-climate benchmark |
| Refrigerant | R-290 (newer range) / R-32 | R-32 |
| Installed cost | €11,500–€15,500 | €11,000–€15,000 |
| SEAI grant | Up to €12,500 | Up to €12,500 |
| Irish installer network | Large, long-established | Largest in Ireland |
| Warranty | 5 years parts & labour | 5 years (extendable to 7) |
Verdict: genuinely close. Daikin edges the SCOP on paper and usually the price; the Ecodan answers with the stronger cold-weather rating, a straightforward 5-year parts and labour warranty, and controls installers prefer. For a larger home, an exposed site, or anywhere that gets real frost, we lean Ecodan: the extra few hundred euro buys headroom. For a well-insulated three-bed in a mild coastal county, the Daikin's small price and efficiency edge makes it hard to beat. Get both quoted.
Mitsubishi Ecodan: Frequently Asked Questions
Are Mitsubishi heat pumps any good?
Yes. The Ecodan ranks #2 on our best heat pumps in Ireland list. It carries a SCOP of around 4.4, is rated to keep working down to −25°C, comes with a 5-year parts and labour warranty, and the FTC controller is consistently praised by installers. Its long history in Irish homes means plenty of local installers know it well. The only real knock is that it typically prices slightly above the equivalent Daikin.
Which Mitsubishi Ecodan model is best?
For most Irish homes, the Ecodan R290 range (5–12 kW) is the one to ask for: it uses future-proof R290 refrigerant, reaches flow temperatures up to 75°C so more retrofits keep their radiators, and operates down to −25°C. The older Ultra Quiet R32 range is still a solid buy where noise near a boundary matters. The exact kW size should come from your installer's SEAI heat loss survey, not the brochure.
How much does a Mitsubishi Ecodan cost in Ireland?
Typical quotes run €11,500–€15,500 fully installed before the grant: a standard three-bed retrofit at the lower end, larger homes needing a bigger unit or radiator upgrades at the upper end. After the SEAI grant of up to €12,500, the net cost for qualifying homes falls substantially.
Is the Mitsubishi Ecodan eligible for the SEAI grant?
Yes. Ecodan models are on the SEAI approved product list. The grant of up to €12,500 (€6,500 heat pump + €2,000 heating upgrade + €4,000 renewable heat bonus) applies as long as the installer is SEAI-registered and your home was built before 2021.
Mitsubishi Ecodan or Daikin Altherma: which should I choose?
They're closely matched. Daikin edges the SCOP (~4.6 vs ~4.4) and usually the price, and has Ireland's largest installer network. The Ecodan counters with a −25°C cold-weather rating, a 5-year parts and labour warranty, and the well-liked FTC controls, our pick for larger homes and exposed sites. Get both quoted and compare like for like.
Who installs Mitsubishi Ecodan heat pumps in Ireland?
Ecodan systems are fitted nationwide by SEAI-registered heat pump installers, and because the brand has been in Ireland for years, most counties have several installers experienced with it. Ask specifically for the Ecodan R290 when requesting quotes, confirm the installer is SEAI-registered (required for the grant), and check their accreditation with Mitsubishi Electric: the 5-year parts and labour warranty depends on it.
