Sizing Guide

There is a Livella floor heating system for every home and family. Use the sizing guide below to select the perfect heater for the area that you wish to heat. Choose a UF15 under floor / in screed heater for energy-efficient and on-demand operation, and an IS35 in slab heater in new homes with access to off-peak electricity prices.

Match a reliable and efficient Livella-brand heating cable with a KT0500 Installation Kit for a complete package; including a programmable thermostat, floor temperature sensor, fixing consumables and installation monitor.
