Air Handlers. Many homeowners today want to air-condition their homes, and fresh air ventilation is an important requirement in modern building codes. Air Handling units or “fan coils” are becoming a common way to satisfy these needs using hot water as the heat source.
Ultra-Thin Hydronic Fan Coil HTP's Ultra-Thin Fan Coils are based on the forced-convection heat transfer technology which makes the heat dissipation more efficient. Compared with the traditional heating radiators, the units can save more than 30% energy consumption.
Hot water also can be provided by solar hot water systems, which are commonly used to supplement fuel-based systems. Distribution: In-floor systems are usually distributed by hot water flowing through plastic tubing. Advantages: Radiant systems provide comfortable, even heat. When heated by boilers, radiant systems can be very energy efficient.
CERTIFICATION. All fluid coils designed with 1/2” or 5/8” tubes are to have ARI Standard 410 certification and shall bear the ARI symbol. Coils outside the scope of ARI’s standard rating conditions or certification program will be acceptable to ARI since USA Coil is a current member of the ARI coil certification program, and coils will be rated in accordance with the ARI Standard 410.
The heat exchanger in a water to air heating system is then placed inside of an air handler or blower compartment where a blower fan circulates building air from return ducts to a plenum where air is blown across the heat exchanger and then the warmed air is delivered to the occupied space through additional warm air ducts or radiators .Water
Jul 17, 2017· A gravity hot water heating system is the oldest and simplest system to heat homes. It is also the least efficient. In a gravity system, the circulation of water is due primarily to thermal and density differences between hot and cold water. As water heats, it expands, displacing the cooler and less dense cooler water throughout the system.
As its name implies, a fan coil unit consists of a heat exchanger in which water is circulated and a fan assembly, incorporating a filter and simple controls, designed for wall perimeter units (Fig. 24.9) or ceiling units mounted within ceiling voids.Ceiling units can be configured as a cassette, drawing air into the centre and discharging at the periphery.
The combination system uses hot water as its single source of heat. The MaxAir Air Handler contains a space heating fan coil that uses hot water circulating through the fan coil to distribute warm air throughout the house. An energy efficient electric motor housed with the air handler drives the fan which pushes the warm air through the duct
How They WorkA Hydro-Air system is a combination of a hot water and a hot air system. This type of system incorporates a hot water boiler, either oil or gas fired, which heats water and sends it through pipes to a coil in an air handling unit. As hot water heats up the coils, a blower then passes air over the coils.

How Hydro-Air Heating WorksNov 11, 2016· Hot water boilers have a minimum of 82% for gas models and 84% for models that run on oil. Energy.gov says boiler vs. furnace energy efficiency can also be compared by noting certain equipment features. In addition to looking at AFUE percentages, Energy.gov suggests taking note of whether or not the heating system has a pilot light.

Which of the following statements about fan coil units combined with make-up air systems is FALSE? a. The units include a disposable filter, fan and heating/cooling coil. b. Ventilation is provided by a 100% outside air system. c. The air handling unit includes filters, heating coil, cooling coil and supply fan. d.
If you already use a hot water radiant system to heat your home, adding heat to your garage can be accomplished by installing a hot water garage heater. Hot water garage heaters transfer heat from the hot water to the air. The hot water from your boiler flows through a radiator coil and an electric fan pushes air through the radiator coil.
Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity. 30000 - 79999 (87) 80000 - 129999 (160) 130000 - 179999 (143) 180000 - 229999 (71) 230000 - 279999 (44) 280000 - 329999 (14) 330000 - 379999 (8) 380000 - 429999 (3)
