Boiler: The boiler or heating source heats the water to the desired temperature. Check out the different BOILERS Indirect hot water maker: runs off your boiler to provide instant, never ending domestic hot water. LEARN MORE Fan Coil: Similar to a furnace but runs off your boiler instead of a burner. Basically a coil of copper pipes run through the fan coil containing hot water from the boiler and a fan blows air across these coils and heating the air to distribute it throughout the house. The fan coil uses the same sheet metal plenums as a normal furnace, so replacing your furnace with a fan coil is easy. Since there are no moving parts besides the fan, a fan coil can last as long as the house with a fan replacement every 20-25 years approximately. If that’s not going to save enough money then it’s even better to know that a fan coil is less expensive than a furnace as there is no gas valves, gas lines, exhausts or intake air. Humidifiers and air conditioning work the exact way with a fan coil as with a furnace. Zones: A zone is a room(s) that is heated with an individual thermostat. Kensington’s showhome has two zones in the basement and one zone in the garage. Solution: The fluid that runs through the floor is a mixture of 30% glycol(antifreeze),  5% boiler treatment & 65% water. Air eliminator: Air is not wanted in a hydronic heating system because it would rust the iron components of the system and could create a no water flow situation so removing air with a separator is crucial. The air clings onto a metal cage and rises up and through a vent in the separator. LWCO: Low water cut off; shuts power off to boiler when there is low water in the system. Expansion tank: Hot water expands and the expansion tank has a bladder inside to provide expansion to the system as seen to the right. Glycol feeder: Will increase the pressure of system when air is released by injecting glycol into the system Exhaust & intake air: All combustion air is drawn from outside, used for combustion and then expelled eliminating any need for combustion air, thereby decreasing heating costs. The exhaust from the boiler is released out the side of the house and is cool enough to use plastic pipe. Pressure: The standard pressure in the system is around 15 psi Headers(Manifold): This is where the tubing in the floor is connected. Each zone has a set of headers; supply and return. PVC sleeve: Protects the tubing as it passes through the concrete Air test: Each header is tested with 70 psi of air while the concrete is being poured and until it is connected to the boiler Tubing: The tubing is ran at 12” centers in most areas except on exterior walls and bathrooms where it is installed on 6” centers because of greater heat loss and a need for warmer floors. The tubing is installed in roughly 250 ft loops, any longer and cool spots may appear. The tubing has an oxygen barrier coating on the outside to prevent air from penetrating the system Pressure relief valve: This is a safety device to protect the system from over pressuring Combustion analyzing: The boiler is analyzed to ensure the highest efficiency is used since different altitudes will change the operation of the boiler. All boilers and furnaces need this done but unfortunately most don’t. Zone valve: Theses valves are operated by the thermostat, when the thermostat calls for heat then the zone valve opens and the pump starts to circulate hot water through the floor to satisfy the thermostat. Alpha Pump: This high efficient pump throttles down or up depending on the load. More thermostats calling, the higher the GPM while if a small zone is calling for heat the pump will run at low speed. The alpha also displays how many watts and GPM it is using. Hydronic drawing: Each hydronic job needs to have a drawing made up of the tubing layout and a heat loss calculation done on the building by a hydronic certified designer. Luckily for Richfield, we have a designer.
