Specifications

Features

Elevate your home comfort with the ThermoGroup Thermonet 150-200W/m² Undertile/In Screed Floor Heating Kit, a system designed for both performance and modern convenience. This versatile kit offers two targeted solutions: the 150W/m² option for efficient undertile installation in large area and the 200W/m² version for in-screed applications where floor space is often limited like bathrooms. Available in a practical size range from 2m to 32m, it can be customized to fit any room layout. The mat itself is remarkably slim at just 3.5mm thick, ensuring easy integration into your floor build-up.

The true highlight of this kit is the smart Wi-Fi thermostat, which provides unparalleled control by allowing you to manage your heating system directly from your smartphone or the device itself. This smart feature, combined with a safe maximum temperature of 28°C and a completely waterproof IP68 rating, ensures durable and worry-free operation. Transform your space with the perfect blend of customizable warmth and intelligent, connected home comfort.

  • Select the corresponding number of insulation board based on your thermonet size and coverage.
  • • NEVER CUT THE HEATING CABLE!

Shipping

Delivery timeframes, order processing, pickup and delivery charges — everything about getting your order to you.

Last updated 15 July 2026

Free shipping to Greater Sydney, online orders
0–3 days to process and dispatch your order
2–7 days metro delivery after dispatch

01 Free shipping

  • Free shipping to Greater Sydney on online orders only.
  • Large or bulky items to other regions require a freight quote. Start a Live Chat (chat icon, bottom right) and we'll quote it for you.

02 Standard delivery timeframes

Destination Delivery time after dispatch
Metro areas (all states) 2–7 business days
Regional areas (all states) 7–15 business days
Timeframes are estimates counted in business days from the date of dispatch, not from the date of order. The actual delivery time depends on the courier carrying your parcel.

03 Order processing & delays

  • You'll receive an Order Confirmation Email as soon as your order goes through.
  • Please allow 0–3 business days for processing — in most cases we dispatch within the first 24 hours.
  • Once your order ships, we'll email you the tracking information.

Some delays sit outside our control:

  • Public holidays, peak periods and sale periods add time. During Christmas and major sales, please allow extra.
  • High order volumes may occasionally extend the timeframe slightly.
Remote areas: all courier networks have limits. For some remote postcodes couriers will not deliver to the door — your parcel goes to a local depot or Australia Post outlet, and you'll be notified to collect it.

04 Additional delivery charges

Charges beyond the base delivery fee may apply where:

  • Stair or lift access is needed — if the delivery point isn't directly accessible, or goods must be carried up stairs, this adds labour and time.
  • The location is difficult to reach, or two or more people are needed to deliver safely.
These are assessed case by case, quoted and agreed with you before we proceed, and billed on a separate invoice. No surprises.

05 Missed deliveries

  • If nobody is available at the delivery address during the agreed window, a re-delivery fee may apply.
  • Any extra charge will be communicated and agreed with you before a second attempt.
  • Please make sure you or an authorised person is present at the agreed time.

06 Pick up

  • We'll get your order ready as soon as possible and email you a notification with your booking number and collection details.
  • Please wait for that email before coming in.
