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. |
|
|
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 |
| Moves hot water from the boiler
to the radiation. |
|
|
PRESSURE REDUCING
VALVE |
| B&G reducing valves protect heating and plumbing
systems against excessive line pressures. |

BPX BRAZED PLATE HEAT
EXCHANGER |
| BPX Brazed Plate Heat Exchanger
heats the glycol/water mix used in the snow melt system using the boiler water as the heat source. BPX separates the boiler water from the snow
melt water into two independant piping loops. The boiler water and snow melt fluid pass through separate plates in the BPX providing maximum heat transfer
while never coming in contact. |

PRIMARY SNOW MELT
CIRCULATOR |
| Primary Snow Melt Circulator circulates the snow melt glycol
through heat exchanger |
|
|
HFT DIAPHRAGM TANK |
| HFT Diaphragm Tank is used to absorb the force of
thermal expansion on the snow melt loop when the closed loop snow melt system glycol/water
mix is increased and to maintain proper pressurization. |
|
|
SNOW MELT CIRCULATOR |
| Snow Melt Circulator circulates the water/glycol mix
through the buried tubing in the snow melt system. |
|
|
EASB-JR AIR SEPARATOR |
| EASB-JR
Air Separator removes entrained air including
micro-bubbles in the snow melt loop making system more efficient, operate quieter and last
longer. |
|
|
COMFORT-TROL™
ZONE CONTROL VALVE |
| Another way to zone a hot water
system is to use electric zone valves. The
zone valve takes the place of the Flo-Control valve. Each
zone valve acts as a "Gatekeeper" to the zone
it serves. The circulator
provides the water, and the zone valve allows that water to either pass or not pass. |

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