Underfloor Heating Wellington: Your Complete Guide to Installation and Benefits
If you live in Wellington, you’ll know how our cool temperatures, wind, and damp conditions can make staying warm a real challenge. At Livella Underfloor Heating, we specialise in underfloor heating solutions designed specifically for Wellington homes, delivering consistent, comfortable warmth without cold spots or draughts.
Underfloor heating is one of the most effective ways to heat a home in our climate. Instead of blasting warm air around the room, heat gently rises from the floor up, creating an even, natural warmth that feels better and costs less to run over time.
In this guide, we walk Wellington homeowners through everything you need to know about underfloor heating—from system types and installation options to costs, energy efficiency, and retrofitting existing homes. Whether you’re building a new home in the Hutt Valley, renovating a classic Wellington villa, or upgrading your heating on the Kapiti Coast, we’ll help you make an informed decision.
By reading this guide, you’ll gain:
- A clear understanding of which underfloor heating system suits your Wellington property
- Realistic expectations around installation timeframes and costs
- Practical solutions for retrofitting underfloor heating into existing homes
- Clear next steps for working with our team at Livella Underfloor Heating
Understanding Underfloor Heating Systems
Underfloor heating works by distributing heat evenly beneath your floor surface, allowing warmth to radiate upwards and gently heat the room. This radiant heat warms people and objects directly, rather than relying on hot air circulation like radiators or ducted systems.
For Wellington homes, this makes a noticeable difference. Windy conditions reduce the effectiveness of air-based heating, while underfloor heating delivers steady warmth that combats the damp chill common throughout our long cooler season.
Underfloor Heating Applications in Wellington
Now let’s look at how underfloor heating works across different Wellington housing scenarios.
New Build Installation
For new builds, underfloor heating is easiest and most cost-effective to install. You embed the heating cables directly into the concrete slab during construction, creating a system that uses the slab as thermal mass.
This allows the floor to store heat and release it gradually throughout the day—perfect for Wellington’s steady, cool conditions. The result is stable indoor temperatures, lower running costs, and no need for wall-mounted radiators. For best results, we recommend planning underfloor heating early in the design stage.
Renovation and Retrofit Options
Many Wellington homeowners assume underfloor heating isn’t possible in existing homes—but that’s not the case. Overlay systems add as little as 15–25mm to floor height, making them ideal for renovations where the original slab can’t be accessed.
Homes with timber floors or subfloor access may allow heating to be installed beneath the floor, although flooring type plays a role in efficiency. Tiles and polished concrete perform best, while carpet and timber require careful system design.
Multi-Zone Control Systems
Modern underfloor heating systems offer advanced zoning control, allowing you to heat different areas of your home independently. Living spaces can be warmer in the evenings, bedrooms cooler overnight, and bathrooms warmed in the morning—all automatically.
For Wellington households with varied room usage, zone control improves comfort while reducing unnecessary energy use. Smart thermostats can also respond to weather changes, optimising efficiency throughout the year.
Wellington Electric Underfloor Heating System Cost Guide
| System Type | Installation Cost | Typical Running Cost | Maintenance Cost | Lifespan |
|---|---|---|---|---|
| Electric Underfloor Heating – In-slab | $900 – $3,000 per room | ~ 6c per m², per hour | $0 | 25+ years |
| Electric Underfloor Heating – On-slab (Screed/Mats) | $900 – $1,500 per room | ~ 3c per m², per hour | $0 | 25+ years |
| Hydronic In-slab Heating | $12,000 – $25,000+ whole home | Variable (depends on gas/electric heat source) | ~$300–$800 per year | 20–30 years |
| Ducted Heating (Reverse Cycle or Gas) | $8,000 – $20,000+ whole home | Variable (higher for whole-home use) | ~$150–$400 per year | 10–15 years |
Summary:
- In-slab electric suits new builds where thermal mass is desired, with predictable running costs and no maintenance.
- On-slab electric is ideal for renovations, with faster heat-up times and lower running costs per m².
- Hydronic heating can perform well in large, highly insulated homes but involves high upfront costs, complex plant equipment, and ongoing servicing.
- Ducted heating has lower install cost than hydronic for whole-home coverage but requires regular maintenance and typically has a shorter lifespan.
Disclaimer:
Actual installation and running costs will vary depending on room size, insulation levels, electricity or gas rates, climate, system design, and usage patterns.
Common Challenges and Solutions
Problem
High Installation Costs
Solution
While underfloor heating costs more upfront than portable heaters, electric systems typically reduce running costs by 20–40%. They also increase property value and comfort.
Problem
Existing Floor Disruption
Solution
Renovation concerns are common, but modern overlay systems minimise disruption. We work with builders and flooring contractors to ensure a smooth process and can focus on key living areas if a full installation isn’t required.
Problem
System Sizing and Design
Solution
Incorrect system sizing leads to poor performance. It best to conduct detailed heat loss calculations specific to Wellington’s climate, wind exposure, insulation, and floor materials—ensuring every room receives the right level of warmth.
Conclusion
Underfloor heating is one of the most effective heating solutions for Wellington homes. It delivers even warmth, removes draughts, operates silently, and improves indoor air quality—making your home more comfortable throughout the year.
