 House Tour
| Radiant Heat Loop |
How does it work?
1. Water is heated in a boiler, either by gas, oil or electricity. |
| 2. Hot water is then pumped through the
pipes to radiant tubing hidden in the floor. |
| 3. As the hot water flows through
the tubing, heat is released into the rooms. |
| 4. Cooler water then goes
back to the boiler where it is reheated and recirculated again. |
| 5. Boiler temperature is based on the
feedback from the room thermostat. When the room temperature drops below the thermostat setting,
a signal is sent to the pump. The pump begins circulating hot water through the system. |

BOILER |
| A boiler
is a closed vessel in which water or other fluid is heated under pressure. The heated
water is circulated though out the system to provide space heating, pool heating, hot
domestic potable water heating, etc. |

GUARD DOG LOW WATER
CUT-OFF |
| A low water cut-off does two things. First, it
accurately detects a low water condition should it occur. Second, it automatically shuts
down the combustion operation of the boiler. This will prevent the boiler from firing
while its water level is too low to properly manage the heat and energy. A low water
cut-off is required by code in many states in the USA and many boiler manufacturers
stipulate that cut-offs are to be routinely installed, especially if radiation is
installed below the level of the boiler. |

EASB-JR AIR SEPARATOR |
| EASB-JR
Air Separator is designed to automatically remove entrained air bubbles in hydronic
systems. As fluid enters the air separator, the velocity is decreased creating a
low-pressure area. The small bubbles are released from fluid and then collect on the
coalescing medium. As the bubbles coalesce, they rise to the top of the air separator
where they are released to atmosphere through the built-in automatic air vent. |

HFT DIAPHRAGM TANK |
| HFT
Diaphragm Tank is used to absorb the force of thermal expansion on the boiler loop
when the closed loop boiler system water is increased and to maintain proper
pressurization. |
|
|
PRESSURE REDUCING
VALVE |
| B&G reducing valves protect heating and plumbing
systems against excessive line pressures. |
|
|
ASME SAFETY RELIEF
VALVE |
| B&G diaphragm operated cast
iron and diaphragm-assist operated bronze ASME Safety
Relief Valves are designed to protect fired and unfired hot water pressure vessels
against over-pressure conditions. |
|
|
PRIMARY CIRCULATOR
PUMP |
| Primary circulator
moves hot water from the boiler to the radiation. |
|
|
HYDROTROL FLOW CONTROL VALVE |
| Hydrotrol Flow Control Valves
is used to prevent overheating of zones due to gravity flow in hydronic heating systems. |
|
|
RADIANT LOOP CIRCULATOR |
| Radiant Loop Circulator
circulate the water through the in-floor radiant heat loops to provide space heating. |
|
|
INJECTION MIXING CIRCULATOR |
| Injection Mixing Circulators
inject water from the higher temperature boiler (primary) loop into a lower temperature radiant (secondary) loop.
The higher temperature water is mixed with the lower temperature water to maintain a desired loop temperature
to match the load requirements. |

Y-STRAINER |
| Y-
Strainer collects dirt and debris in the system to protect the other components in the
system. |
