Hydronic system design manual dectra corporation march 2013 2 the garn unit all related heating equipment including pumps piping fan coils hot water baseboard radiant floor heating systems etc and all electrical equipment including power wiring controls control wiring back up.
For example radiant floor heat has more even floor to ceiling temperatures than other systems since the heat starts on the floor.
But standby losses for six months out of every year can add up.
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.
Step 1 heat loss q btu hr per zone.
Typically 10 of design flow rate yields about 50 of design heat output.
The heat output from most hydronic emitters be they baseboard radiant floor circuits or air handlers doesn t vary in proportion to the flow rate passing through them.
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.
Zurn radiant heating design and application guide radiant panel heating increases our comfort in many ways.
The other consider ation is efficiency.
The temperature profiles of a typical radiant floor heating system and a typical forced air heating system.
Two low or moderately effi cient water heaters are much more costly to run than one high efficiency unit.
