Upgrade existing underfloor or radiator systems
An Ecodan Hot Water Heat Pump is a highly efficient, future-ready replacement for outdated gas, diesel, wood, or coal boilers. Designed to integrate seamlessly with existing hydronic radiators or underfloor heating systems, it delivers reliable, comfortable warmth while significantly reducing both energy bills and carbon emissions.
Suitable for both new builds and heating upgrades, Ecodan systems offer a smart pathway to modern, low-carbon living.
Ecodan's Coefficient of Performance (COP) of 5.05*2 means for every 1.19kW of electricity input, you can get up to 6kW of heat output by absorbing free heat energy from the outdoor air.
COP Comparison Chart
Since 1994 Mitsubishi Electric have utilised their heat pump technology leadership and expertise to specifically design and manufacture hot water heat pump solutions. The range is called Ecodan and is now well and truly established globally as the preferred way to heat water efficiently with minimal environmental impact.
New build, renovate or retrofit
Upgrading to an Ecodan system is an investment that delivers immediate power savings and increases property value for future buyers.
Whether building new, renovating, or retrofitting, Ecodan provides the perfect solution for super energy-efficient water and space heating.
Got questions?
Yes an air-to-water heat pump and a hydronic heat pump refer to the same type of heating solution: a heat pump that heats water. The outdoor unit extracts available heat energy from the outside air and transfers it to heat water for underfloor or radiator central heating and domestic hot water.
Hydronic Split ecodan: The refrigerant to water heat exchanger built into the outdoor unit. Water pipes connect the outdoor unit to the indoor unit.
Refrigerant split ecodan: The refrigerant to water heat exchanger is built into the indoor unit (cylinder or hydrobox), refrigerant pipe connects the outdoor unit to the indoor unit. This type of system has practical advantages such as longer pipe run and less heat loss, suitable for cold regions like Otago.
Yes. This is a common consideration for homeowners who already have radiator central heating powered by an older gas or diesel boiler.
Mitsubishi Electric Ecodan may be able to replace the boiler as the heat source while continuing to use the existing hydronic radiator network, subject to a professional assessment. The suitability of the existing radiators, pipework, insulation levels and overall system design should be checked before replacement.
Ecodan is an excellent heat source for underfloor heating and in most cases you can swap the existing boiler and keep the existing underfloor heating system. The new system will need to be sized correctly by a professional installer. See our where to buy section for ecodan installers in your area.
Hydronic underfloor heating should be considered as early as possible in the new-build design process, ideally during concept design or early planning.
This is because the underfloor pipework is usually built into the floor slab, so it needs to be planned before construction begins. Early consideration also allows the heating system to be designed alongside the home's insulation, glazing, flooring choices, room layout and controls.
Yes in many homes, a hot water heat pump can replace a gas boiler used for underfloor and radiator heating. The ecodan system will need to be sized correctly by a professional installer. See our where to buy section for ecodan installers in your area.
Yes. An ecodan can replace a diesel boiler in homes with existing underfloor and radiator central heating.
Diesel boilers are often found in larger homes or colder regions, and older systems can involve high winter running costs, servicing requirements and reliance on fossil fuels. The ecodan system will need to be sized correctly by a professional installer. See our where to buy section for ecodan installers in your area.
A fan coil is an indoor unit that can be connected to a hydronic heating system. Warm water from the hot water heat pump passes through the unit, and a small fan helps move warm air into the room.
Fan coils can be useful where underfloor heating or radiators are not suitable, or where a faster response is needed in selected rooms. System suitability depends on the home, the heating requirements and the overall hydronic design.
