Description

Embedded floor heating systems produce a uniform heat over the entire floor area, providing direct radiant comfort from lowtemperature heat stored within the slab.

This bulletin describes the design, installation, commissioning and maintenance requirements of 2 types of systems:

1. piped hot water (hydronic) and
2. electric heating.
