Warmup Underfloor Heating: A Space-Saving Heating Option Perfect for Renovations

In contrast to bulky radiators that occupy precious wall space and constrain layout options, Warmup underfloor heating is inconspicuous, concealed beneath the floor, and operates silently, making it ideal for bedrooms and quiet living zones. This system allows for open room designs, providing more space for furniture and larger windows. Many homeowners express that “you don't even know it's there — apart from the warmth.”

Warmup systems are compatible with all kinds of flooring, including tile, carpet, inslab, laminate, and wood to retrofitted floors, making them perfect for seamlessly integrating old and new sections during renovations. This results in equally distributed, draught-free warmth throughout the home, eliminating cold spots.

The radiant heat gently warms the room from the ground upward, improving air quality by minimising dust movement and allergens, thus contributing to a healthier living environment. Bathrooms and wet areas benefit particularly well, as the heated floors remain dry, helping to prevent mould and dampness

Energy efficiency is another significant benefit. With zoning options, homeowners can heat only the areas they are using, reducing energy consumption and providing long-term cost savings — all while lessening their environmental impact.

Warmup underfloor heating is entirely safe, waterproof, and designed for longevity. Its heating elements and controls are approved and certified to both New Zealand and international standards. The BRANZ appraisal and Lifetime warranty* on undertile heating elements further enhance Warmup's credentials and strengthen its reputation for quality and compliance

Warmup underfloor heating is a future-ready investment for any home renovation. It offers unparalleled comfort, safety, energy efficiency, and stylish design integration, making it the ultimate heating solution for modern additions and alterations.

Warmup Undertile Heating is a system of low-temperature electric radiant elements which are laid directly under the floor covering and deliver luxurious and efficient heating for residential and commercial properties, including wet areas.

Warmup Undertile Heating has been appraised (BRANZ Appraisal 644 [2017]) for use in internal dry and wet areas of buildings within the following scope:

on structural substrates of concrete, plywood or compressed fibre cement sheet (excluding particle board flooring); and,
with optional floor overlays of fibre cement tile underlays or Warmup Insulation Backer Board; and,
when protected from physical damage by a screed and ceramic or stone tiles; and,
where floors are designed and constructed such that deflections do not exceed 1/360th of the span; and,
movement and control joints in the substrate must be carried through to the screed, tile or stone finish; and,
the design and construction of the movement and control joints is specific to the building and therefore the responsibility of the building designer and building contractor and is therefore outside this scope; and,
when used in a wet area a waterproofing system must be used; and,
where floors are designed not to exceed a continuous operating temperature of 35°C; and,
the system must be installed using detailing as set out in the Technical Literature; and,
Warmup Undertile Heating must be installed by trained applicators, approved by Warmup New Zealand Ltd

It is important to review the size of the room that is being heated and check for movable and immovable features or furniture in the room. This will determine the actual area to be heated and the size of the heating element required. (the floor under cupboards does not need to be heated).
