Hot Water Heat Pumps
Underfloor Heating
Luxurious warmth from the ground up, perfect for new builds and renovations. Ecodan Hot Water Heat Pumps provide efficient, reliable central heating throughout your home, delivering consistent comfort when paired with underfloor heating systems and advanced Mitsubishi Electric controls.
About the technology
What is Underfloor Heating?
Underfloor heating, also known as hydronic radiant heating, is a modern heating system where warm water flows through pipes installed beneath your floor. Unlike systems that rely on air convection, it provides heat without cold spots. Underfloor heating transforms your entire floor into a gentle, radiant heat source.
When paired with an Ecodan hot water heat pump, this system becomes incredibly efficient. Heat pumps extract renewable energy from the outside air and use it to warm the water circulating through your floors—providing sustainable comfort even on the coldest New Zealand days.
Key Benefits
Invisible Comfort
No visible heating appliance on the wall. Your floor becomes the heating system, freeing up wall space and enhancing interior design.
Even Heat Distribution
Heat rises naturally from the floor, creating consistent warmth throughout the room without cold spots or temperature variations.
Energy Efficient
Operates at lower water temperatures than traditional high temp radiators, reducing energy consumption to maintain the same level of comfort.
Healthier Living
Reduces dust circulation compared to forced air systems, and maintains optimal humidity levels for better indoor air quality.
Step by step
How Underfloor Heating Works
A simple yet sophisticated system that delivers consistent warmth throughout your home.
01
Warm Water Circulation
Your Ecodan heats water to a comfortable 35–45°C, much lower than traditional radiator systems.
02
Pipe Network
Warm water flows through a network of pipes embedded in your concrete slab, floor screed or mounted beneath timber floors.
03
Radiant Heat Transfer
The floor surface warms gently and radiates heat upward, warming objects and people in the room naturally.
04
Zone Control
Smart thermostats in each zone maintain your desired temperature automatically, room by room.
Versatile and compatible
Ideal for New Zealand Homes
Underfloor heating works beautifully with various floor types and is particularly well-suited to New Zealand’s climate and building styles.
