Whether it’s a touch of luxury or a practical necessity, underfloor heating systems can be a game-changer for homeowners, especially during Auckland’s cooler months. From keeping your bathroom toasty to heating larger living spaces, underfloor heating systems provide an energy-efficient way to ensure warmth throughout your home. But with several types available, it can be hard to decide which system is right for you. Here’s a comprehensive guide to help you make an informed decision on the best underfloor heating systems for your home.
Types of Underfloor Heating Systems
There are five main types of underfloor heating systems, each with its own advantages and considerations. These include:
- Electric Underfloor Heating
- Hydronic Underfloor Heating
- In-Screed Systems
- Under Tile Heating Systems
- In-Slab Systems
Let’s explore each option in more detail.
Electric Underfloor Heating
Electric underfloor heating is one of the most popular options, especially for homeowners looking to retrofit heating into an existing space. This system uses low-voltage electric cables that are installed beneath the floor, either coiled or embedded within a mat. It’s relatively easy to install, especially under floorboards.
However, while electric underfloor heating is convenient, it can be costly to run, particularly in larger spaces. To maximise efficiency, the floor must be well-insulated to prevent heat loss. Additionally, this system takes longer to heat up compared to some other types, which is something to keep in mind when planning your home’s heating needs.
Hydronic Underfloor Heating
Hydronic underfloor heating is often seen as the gold standard for large spaces. This system involves pipes filled with hot water, which circulate under the floor and heat the surface above. Hydronic systems are energy-efficient and can be powered by natural gas, solar energy, or heat pumps, making them more cost-effective to run in the long term.
While the operational costs are lower, hydronic systems can be expensive to install, especially if retrofitted into an existing home. However, if you’re building a new house, this system is a highly efficient option for long-term heating.
In-screed Systems
For those looking for a durable and cost-effective solution, in-screed systems offer excellent value. These systems involve placing heating coils above a waterproofing membrane, which are then covered by a screed – a cement and sand mixture that levels the floor. Once installed, this system provides a secure, long-lasting heating solution.
One concern with in-screed systems is the risk of damage during installation, as the coils can break while the screed sets. However, many systems come with built-in alarms that alert you to any breaks in the coil, allowing repairs to be made before the flooring is completed.
Under Tile Heating Systems
Under tile heating systems are ideal for rooms where you need quick, direct heat, such as bathrooms. The system heats up faster than most other types, which makes it a good option for small, high-use areas. However, this system is more fragile, and any damage to the cables may require the entire floor to be replaced – making it less ideal for long-term use in large spaces.
If you opt for under tile heating, it’s important to ensure the cables are installed correctly and safely to minimise the risk of damage.
In Slab Systems
In-slab systems are ideal for new builds where heating coils can be directly embedded into the concrete slab of your home. This method is cost-effective, as the heating is installed during the construction process, and it’s also energy-efficient since the thermal mass of the concrete slab retains heat well.
While this system is not recommended for retrofitting, it’s a top choice for those building a home from scratch who want a low-maintenance, long-term heating solution.
Choosing the Right Underfloor Heating Systems
The best underfloor heating systems for your Auckland home depend on several factors:
- Your budget: While hydronic systems offer energy savings in the long run, their upfront costs can be high. Electric systems may be cheaper to install but can become costly to run if not managed carefully.
- The size of the space: Large open areas will benefit more from hydronic or in-slab systems, whereas smaller rooms like bathrooms can make the most of electric or under tile heating.
- Building type: If you’re retrofitting a system into an existing home, electric and in-screed systems are easier to install. For new builds, in-slab heating offers the most seamless integration.
Conclusion
Underfloor heating is an excellent way to enhance comfort and energy efficiency in your home. Whether you choose electric, hydronic, in-screed, under tile, or in-slab heating depends on your specific needs, budget, and the layout of your home. Before making your decision, consult with a qualified Auckland electrician to discuss your options and ensure you select the right system for your space.
