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.

Performance – heat output

Nu-Heat’s LoPro®Max system offers an impressive heat output that’s around 50% higher than most other retrofit UFH systems on the market. 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.
