A retrofit underfloor heating system specifically designed for retrofit, whole-house projects, extensions, conservatories and properties with lower levels of insulation.

One of the highest heat outputs available and outstanding response times make LoPro®Max a perfect replacement for a radiator system. Its low height build-up – averaging just 22mm – allows LoPro®Max to be laid on top of existing floors, ideal for running from old rooms to new extensions.

LoPro®Max benefits

  • Outstanding thermal conductivity – heat outputs up to 120W/m2
  • Super-fast response time – can be timed and run as you would a traditional radiator system
  • Just 22mm average height increase over existing floor level
  • Laid over an existing floor with minimal disruption
  • Simple and quick to install
  • High structural and compressive strength
  • One-third of the running cost of electric UFH

Performance – heat output

Nu-Heat’s LoPro®Max system offers an impressive heat output that makes it perfect for renovation projects. As a general rule, hard finishes such as tile and stone will produce the highest heat outputs followed by timber and carpet. Nu-Heat includes heat loss calculations to verify the suitability of the chosen floor finishes and ensure heat output will meet expectations for all fully designed LoPro®Max systems.

Repair the floor, filling any gaps

Fit the isolation strip and double sided tape around the edge of the rooms

LoProMax install step 1

Step 2: Lay the tube and connect to manifold

Lay the panel and tube and connect to manifold and pressure test

Fit the expansion strips in doorways, then the floor temperature sensors

Step 3: Mix and pour the compound

The compound is easily mixed by hand or machine

For areas over 100m², we recommend using a screed specialist
