Key highlights
❄️
T-CAP — 100% capacity to −15°C
T-CAP (Total Capacity) technology maintains every kW of rated heating output down to −15°C — the same point where standard heat pumps are running at 60–70% capacity. Critical for cold Irish winters in exposed locations
⚡
SCOP 4.80 — near class-leading
The second-highest SCOP in this directory behind Samsung EHS. For a home spending €2,000/year heating with a boiler, switching to the Aquarea T-CAP could reduce that to under €700
🌐
Aquarea Smart Cloud

💡 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 Panasonic Aquarea T-CAP 9 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.
The heat pump unit is one component of a complete home heating system. Below is a realistic breakdown of what a full installation in an Irish home typically costs — and what the SEAI grant covers.

With a SCOP of 4.80, the Panasonic Aquarea T-CAP 9 kW produces 4.80 kWh of heat for every 1 kWh of electricity consumed. For a typical Irish home using ~12,000 kWh of heat per year, the pump needs approximately 2,500 kWh of electricity — at the current average Irish electricity rate of ~€0.38/kWh, that is ~€950 per year. Compare that to a typical oil boiler consuming ~900 litres at €0.90/litre (€1,080/yr). Annual saving: approximately €130. Switching to a Night Saver or smart tariff can reduce heat pump electricity costs by a further 20–30%, improving savings further.
The Panasonic Aquarea T-CAP 9 kW has a typical installed price of approximately €13,000 (including the hot water cylinder — sourced separately, installation and commissioning). The maximum SEAI heat pump grant from 3 February 2026 is €12,500 for houses switching from fossil fuel heating — made up of: ① €6,500 Heat Pump Equipment Grant, ② €2,000 Central Heating Upgrade Grant (if radiators need work), ③ €4,000 Renewable Heat Bonus. After the maximum grant, the effective cost is approximately €500. Apply at seai.ie before installation begins — you must receive a Letter of Offer first.
SEAI requires a minimum BER rating of B3 or above (or a satisfactory Heat Loss Indicator result) before approving a heat pump grant. Practically, the Panasonic Aquarea T-CAP 9 kW — with a maximum flow temperature of 60°C — is most efficient in a well-insulated home. Attic insulation, wall cavity fill and draught-proofing are the most cost-effective first steps. SEAI offers separate grants for insulation under the Better Energy Homes scheme. Your installer will complete a heat loss assessment and BER advisory during the site survey — this assessment is a requirement of the grant process and a separate SEAI grant of €200 is available to cover it.
The Panasonic Aquarea T-CAP 9 kW operates at a maximum flow temperature of 60°C. Radiators in older Irish homes are often sized for boiler temperatures of 70–80°C — at 60°C, they may deliver less heat than they would with a boiler, meaning the coldest rooms on the coldest days may need the radiators upsized. In practice: homes built after 2000 with well-sized radiators usually require minimal changes. Homes built before 1990 with older small radiators may need the largest radiators replaced or supplemented. Your installer will carry out a room-by-room heat loss calculation and radiator assessment as part of the SEAI grant survey — this is mandatory before grant approval.
T-CAP (Total Capacity) is Panasonic's cold-weather performance technology. It uses a flash injection circuit to maintain 100% of the rated 9 kW heating output down to −15°C outdoor temperature. In practice this means: on the coldest Irish winter days when your home needs the most heat, the Aquarea T-CAP delivers full output — while standard heat pumps are running at 60–70% capacity. This reduces reliance on the backup electric heater (which uses far more electricity per kWh of heat), keeping your annual running costs lower than the SCOP rating alone suggests for exposed rural locations.
A well-maintained Panasonic heat pump should last 15–25 years. The compressor unit typically lasts 15–20 years; the overall system can last longer with component replacement. Annual servicing by a qualified heat pump engineer is recommended — SEAI-registered installers typically offer annual service packages. The standard 5-year warranty covers manufacturing defects. Heat pumps have far fewer moving parts than boilers — no combustion, no flue, no annual gas safety certificate — reducing long-term maintenance burden.
T-CAP (Total Capacity) is Panasonic's proprietary cold-weather performance technology. Standard heat pumps use a simple inverter compressor that de-rates output as outdoor temperature falls — at −10°C a standard unit might deliver only 65% of its rated capacity. Panasonic T-CAP uses a flash injection circuit that maintains 100% rated capacity to −15°C. This matters in Ireland during cold snaps in January and February when outdoor temperatures in parts of Leinster, Munster and Connacht can fall to −8 to −12°C. At these temperatures, a T-CAP Aquarea delivers full heat output without electric backup.
Yes — particularly for exposed rural locations in the midlands, west and northwest of Ireland that experience more frequent temperature drops to −5 to −12°C than coastal urban areas. The T-CAP technology ensures full heating capacity during these cold spells. The 9 kW model suits most 3–4 bedroom detached homes with good insulation. A heat loss assessment will confirm the correct size before installation.
