Ecodan Hot Water Heat Pump for Underfloor Heating — Residential Homes
Description

Mitsubishi Electric Ecodan Hot Water Heat Pumps are designed for comprehensive home heating solutions, with the ability to cover both hot water needs and efficient underfloor room heating through a single system. An Ecodan Hot Water Heat Pump system features an outdoor unit which connects to a choice of an indoor hot water cylinder or an indoor Hydrobox unit. 

As traditional gas and diesel central heating systems face rising operational costs, the Ecodan range presents an efficient and low emission alternative with its air-to-water heat pump technology. Boasting a Coefficient of Performance (COP) of up to 5.06*¹, indicating higher energy efficiency compared to standard heating methods. 

Using an Ecodan Hot Water Heat Pump for an underfloor heating system is particularly suitable for new-build homes, providing evenly distributed radiant heat and quiet operation. This form of radiant heating is concealed, making it a fitting choice for modern homes with open-plan layouts, high stud, and exposed ceilings where aesthetics and comfort matter.

Built-in smart energy monitoring allows for simple, tailored control

On-screen power usage information means users have the visibility and freedom to efficiently manage overall hot water power consumption. Daily and weekly timers help take advantage of off-peak tariffs and save even more on power bills.

The hot water central heating system is available with Zone Control which allows set different temperatures for different rooms or to turn it off completely.
