Our Underfloor Heating Solutions
Grammar Electrical provides two main types of underfloor heating systems for installation or replacement:
Best for existing homes and renovation projects. We install or replace heating cables and electric mats under the floor surface. This system is easy to retrofit and offers consistent warmth without increasing floor height.
Ideal for large areas or new builds. Hydronic systems use warm water running through pipes installed underfloor. They are efficient, long lasting, and more cost effective over time, especially for bigger spaces. Your type of floor, timber, tile, stone, or laminate, helps us determine which underfloor heating system or replacement option suits your space best.
Is Underfloor Heating
Expensive to Run?
In most cases, no.
Radiant heating warms the entire room evenly, allowing the system to operate at lower temperatures than many traditional heating systems. With proper insulation and a correctly heating installed system, running costs stay manageable and can even be lower over time.
Our Installation &
Replacement Process
Whether installing a new system or replacing an old one, Grammar Electrical follows a professional, safety-focused process:
We assess your space, insulation, existing system (if applicable), floor type.
We make sure the subfloor is dry, level, and ready for heating installed safely.
We install new heating cables or warm water pipes underfloor, or replace old components with modern, reliable systems. We also install thermostats and ensure full compliance with NZ standards.
We test the system to ensure the heating warms evenly, efficiently, and safely.

Why Choose Underfloor Heating?
Underfloor heating is one of the most comfortable and efficient ways to heat your home. Unlike traditional heating systems that leave cold spots and uneven temperatures, radiant heating delivers consistent warmth across the entire floor surface. With a properly installed underfloor heating system, you’ll enjoy:
Even, floor-to-ceiling warmth
No visible radiators or vents
Reduced dust movement
Compatibility with most floor types
Lower running costs and improved energy efficiency
A cleaner, modern home layout
If your old system is failing, uneven, or inefficient, we also offer underfloor heating replacement to restore performance and comfort.
About Us
Frequently asked questions
Find answers to frequently asked questions about our Master Electrician NZ services.
No, we do not recommend DIY installation. Underfloor heating systems require precise spacing, proper insulation, correct thermostat wiring, and compliance with New Zealand electrical standards. Incorrect installation can affect how well the underfloor heating warms the floor, reduce energy efficiency, or create safety risks. A qualified underfloor heating electrician ensures the system is safely and correctly heating installed.
The benefits of underfloor heating include consistent radiant warmth, improved energy efficiency, and the elimination of cold spots. Because the system heats from the ground up, your entire space stays evenly warm. It also removes the need for bulky radiators, reduces air movement, and provides a clean, modern finish in any room.
To understand how underfloor heating works, think of it as a radiant heating method. Heating cables or warm water pipes are installed underfloor. When activated, the heating warms the floor surface, and that heat rises slowly and evenly throughout the room. This creates stable, comfortable temperatures without drafts or hotspots.
