Hydronic Radiant Floor Heating Systems Design

All the necessary components of a well engineered and efficient hydronic radiant floor system are explained in a straight forward and non technical manner.

Hydronic radiant floor heating systems design.

For hydronic underfloor radiant heating systems the systematic design process can be described as a 12 step program beginning with the heat loss and ending with the head loss. The heating loads of some buildings are best served through use of different heat emitters. Step 1 heat loss q btu hr per zone. If you are new to radiant heat our design and construction manual is a must read this manual provides a wealth of general information about radiant heat.

I built this web site in 1995. The second section gets down to the nitty gritty details of actual radiant floor installations. This site is dedicated to the advancement of affordable radiant floor heating. The first part contains a general overview of radiant heat and it s various applications.

Slab insulation methods calculating heat loss tubing options system options and much more all written in easy to understand language for the homeowner with pictures and diagrams. The system works via pex pipe a small pump a water heater and a thermostat. While it was done as a new house was being built in my last house i poured a concrete floor on top of a wood framed floor system and could have put radiant heat in that as well. For example it s common for hydronic radiant heating to be used on the first floor of a house while the second floor rooms are heated using panel radiators or fin tube baseboard.

This is about installing hydronic radiant floor heating in a slab floor system.
