Mitsubishi Electric Ecodan R290
The Mitsubishi Electric Ecodan R290 is a monobloc air-source heat-pump range for residential heating and domestic hot water. It uses R290 refrigerant, with a stated global-warming potential of 0.02, and can provide flow temperatures of up to 75°C in suitable operating conditions.
Suitable for new-build and boiler-replacement projects, including homes with radiators or underfloor heating — subject to a heat-loss calculation and technical survey. Available in 5 kW, 6 kW, 8.5 kW, 10 kW and 12 kW, single and three phase, standard and coastal protection.
Features
- Guaranteed operation range down to -25°C ambient.
- A+ hot-water efficiency — minimised energy consumption.
- Colour touch-screen control with intuitive operation.
- MELCloud enabled — remote control, monitoring and technical support.
- Single and three phase; standard and coastal-protection models.
- Stylish aesthetics with flexible outdoor-unit placement.
- Packaged FTC7 cylinder options for a simpler, organised install.
Why consider Ecodan R290?
- R290 natural refrigerant with a stated global-warming potential of 0.02.
- Flow temperatures up to 75°C — useful for some boiler-replacement projects.
- Monobloc air-source heat-pump design.
- Suitable for new-build and boiler-replacement, subject to assessment.
- Heating and domestic hot water in one system.
- Compatible with radiator and underfloor-heating systems, subject to design.
- Available with integrated packaged-cylinder options.
- Designed to support lower-carbon home heating.
A higher maximum flow temperature may help some boiler-replacement projects, but it does not remove the need to check heat loss, radiator output, pipework and system efficiency.
Ecodan R290 model families
Five outdoor-unit families from 5 kW to 12 kW. Exact output and electrical configuration must be confirmed from the product information sheet — not from boiler size or floor area alone.
| Model family | Nominal output | Indicative application |
|---|---|---|
| PUZ-WZ50VAA / PUZ-WZ50VAA-BS | 5 kW | Smaller residential heating requirements |
| PUZ-WZ60VAA / PUZ-WZ60VAA-BS | 6 kW | Small-to-medium residential heating requirements |
| PUZ-WZ85VAA / PUZ-WZ85YAA | 8.5 kW | Medium-to-larger residential heating requirements |
| PUZ-WZ100VAA / PUZ-WZ100YAA | 10 kW | Larger residential heating requirements |
| PUZ-WZ120VAA / PUZ-WZ120VAA-YAA | 12 kW | Higher residential heating requirements |
Compatible FTC7 cylinders
Ecodan R290 pairs with Mitsubishi Electric's FTC7 pre-plumbed cylinders for monobloc heat pumps — packaged, slimline and standard arrangements. Capacity and configuration follow household demand and plant space — confirmed on survey.

Choosing the right cylinder
An initial guide only. Sizing should account for occupants, baths, showers, bathrooms, usage patterns, recovery time and available installation space.
| Household or installation requirement | Cylinder option to investigate |
|---|---|
| Smaller household or moderate hot-water demand | 150 or 170 litres |
| Typical family home | 210 litres |
| Larger household or higher demand | 250 litres |
| Multiple bathrooms or high peak demand | 300 litres |
| Narrow cylinder cupboard | 150 or 170-litre slimline |
| Restricted height or difficult access | 210-litre short configuration, where suitable |
| Larger available cylinder space | 210-litre long, 250-litre, or 300-litre standard |
Packaged-cylinder benefits
A pre-plumbed FTC7 cylinder may help provide a more organised installation by bringing key components together in a factory-prepared package. Depending on the selected configuration, the installation may include:
- Domestic-hot-water cylinder.
- Heating controls.
- Pumps and valves.
- Sensors.
- Associated hydraulic components.
- Connections for the Ecodan monobloc system.
Exact contents should be confirmed against the selected cylinder model and Mitsubishi Electric installation documentation.
Suitable for boiler replacement
Ecodan R290 may be suitable for replacing a gas, oil or LPG boiler where the property can accommodate an air-source heat-pump system. Existing radiators must be tested or calculated at the proposed heat-pump flow temperature. A 75°C maximum does not mean the system should routinely operate at 75°C.
- Retaining suitable existing radiators, or replacing selected radiators where required.
- Retaining or modifying pipework.
- Installing an FTC7 packaged or pre-plumbed cylinder.
- Reconfiguring heating zones.
- Upgrading thermostats and controls.
- Installing external flow and return pipework.
- Reviewing the electrical supply.
- Integrating solar PV or smart-energy controls where planned.
Radiators and underfloor heating
Ecodan R290 can be designed for radiator heating, underfloor heating, mixed systems and zoned arrangements. The design should establish room-by-room heat loss, required radiator output, underfloor circuit capacity, proposed flow and return temperatures, pipework flow rates, hydraulic separation, zone controls and balancing.
Operating at the lowest practical flow temperature will generally be an important part of achieving efficient heat-pump operation.
Which system may suit you?
An initial guide only. Model and cylinder pairings are indicative and must be confirmed by a qualified designer after survey, heat loss, hot-water demand, radiator output, pipework, electrical supply and installation space are assessed.
| Your situation | Arrangement to investigate |
|---|---|
| Smaller home with limited hot-water demand | PUZ-WZ50 or PUZ-WZ60 with 150/170-litre cylinder |
| Typical family home | PUZ-WZ60 or PUZ-WZ85 with 210-litre cylinder |
| Larger home or higher heat loss | PUZ-WZ85 or PUZ-WZ100 with 250-litre cylinder |
| High hot-water demand | PUZ-WZ100 or PUZ-WZ120 with 300-litre cylinder |
| Narrow cylinder cupboard | FTC7 slimline 150 or 170 litres |
| Existing radiators | Ecodan R290, subject to radiator and heat-loss assessment |
| Underfloor heating | Ecodan R290, subject to circuit and control design |
| Uncertain requirements | Property survey before selecting the equipment |
What Pretium Synergy will assess
Before recommending a system, we review whether an Ecodan R290 outdoor unit — and which FTC7 cylinder arrangement (monobloc packaged, Pre-plumbed Slimline, or Pre-plumbed Standard) — is appropriate for your home.
- Property size and construction, and room-by-room heat loss.
- Existing boiler, controls, radiators, pipework and circulation.
- Existing hot-water cylinder and required capacity.
- Outdoor-unit position, noise and clearances.
- Electrical supply.
- Solar PV, battery and EV-charging plans.
- Planning, building-regulation and installation requirements.

The Mitsubishi Electric Ecodan R290 range uses R290 refrigerant and offers flow temperatures up to 75°C in suitable operating conditions. Mitsubishi Electric lists FTC7 pre-plumbed cylinder options in slimline 150/170-litre configurations and standard 150-, 170-, 210-, 250- and 300-litre configurations. Final selection needs a qualified survey, room-by-room heat-loss calculation, radiator and pipework assessment, hot-water-demand review, electrical assessment and confirmation of outdoor-unit and cylinder installation space. Exact model performance, cylinder compatibility, availability, warranty terms and installation requirements should be confirmed before quotation.
