Radiant panels |
Radiant floor has some advantages over radiant ceilings components are the same as in the baseboard radiator system coils of pipe replace individual units A balancing valve is installed on each coil the panel generates a very high temperature and floors must be insulated |
|
|
Coil panels |
Their place near the wall Coils allowed for failure Today coils are made in one piece using synthetic materials |
|
|
Coils in concrete floors |
Coils need to be staple down for floating |
|
|
Hydronic heating sizing |
Calculating for sizing of water distribution systems are based on the required flow and friction in the piping |
|
|
Key to pipe sizing is overall flow rate |

|
The critical choice in selecting pipes |
Is not the size but the heat flow temperature high temperature of boiling can create steam and ruin the system |
|
|
Heating equipment efficiency combustion and fuel storage |
As fuel Burns it requires oxygen which is only one-fifth of the ear volume large air flow rates are therefore required Duct should be open Close to burner Air from outside |
|
|
Today boilers are efficient. |
Useses more heat |
