If you already use a hot water system to heat your home, adding heat to your garage or workshop may be accomplished by installing a fan forced hot water unit heater. Hot water garage heaters transfer heat from the hot water to the air. Operating Principle The hot water from your boiler flows through a radiator coil and an electric fan pushes air through the radiator coil. The air entering the coil absorbs the heat from the water, resulting in a warmer discharge air temperature. The cooler water leaving the coil returns back to the boiler to be reheated for another pass through the radiator coil. Benefits of fan forced hot water unit heaters in garages or workshops: o Clean heat, no odors, no by-products of combustion to vent. o No open flame to worry about. o No messy fuel oil to contend with. o Efficient. o Easy maintenance. o Very reliable. The only moving share is the motor and fan assembly. If a motor fails, it is very simple to replace. o The fan speed may be adjusted on a heap of models. This allows you to dial in the perfective airflow. o Low clearance requirements on units with side piping connections. o Horizontal units have adaptable louvers to support direct warm air where you need it most. o Durable. All unit casings are treated for corrosion resistance and finished with a gray-green baked-on, high solids paint. o Compact and lightweight for simple installation. o Tapped holes in the units casing concede for simple suspension using inexpensive threaded rod. o Large electrical junction boxes concede for simple power wiring. o Huge range of sizes to match the heater to your heating load. If chosen properly, you don’t have to worry regarding underneath or over sizing. o The fan may run in the Summer to aid circulate air. Drawbacks of fan forced hot water unit heaters in garages or workshops: o Water in a cold garage may without apparent effort freeze if there is a failure. o A home boiler scheme is required. If your boiler is down, the heater will not formulate heat. o Hot water piping is required to disseminate the water from your boiler to the hot water unit heater. o Controls may be somewhat more complex due to the integration of your hot water boiler and the unit heater. See the normally asked questions section for typical control sequences. o Fan forced units move huge volumes of air which may kick up dust in your garage or workshop. Unit Configurations: Hot water unit heaters come in horizontal or vertical models. The “horizontal” or “vertical” describes the direction of airflow. A “horizontal” unit heater is quintessentially placed along a wall and blows warm air into the space. A “vertical” unit heater is quintessentially placed along a ceiling and blows warm air vertically down into the space. Vertical unit heaters are specifically employed in very big spaces. Horizontal units are specifically used in littler spaces such as garages or workshops. There are various modifications available. Horizontal and vertical unit heaters are available with “power throw” high CFM fans, high pressure tubes, low outlet temperatures (for high steam pressure applications), special motors and habit coatings. These modifications are seldom used in the typical garage or workshop. Call us for selective information when it comes to customizing a unit to meet your specific needs. Installation Overview: 1) Suspend the unit heater using threaded rods that thread into the self tapping holes located on the unit heaters casing. 2) Install hot water piping from your boiler or wood furnace to the hot water unit heater. 3) Wire the hot water unit heater’s fan motor. 4) Install controls. Commonly Asked Questions: 1) How do I calculate the heating load for my garage or workshop? ANSWER: Call us or use our simple heat load calculator. Do NOT fall for instrumentation that is advertised as will heat up to 400 square feet. Heating a 400 square foot insulated garage in Florida is a lot dissimilar then heating a 400 square foot un-insulated metal garage in Maine. 1 heater may not magically service both 400 square foot spaces. Call us; we are happy to run a elaborate engineering calculation that will aid you pick the perfective heater for your space. You do not want to undersize, and you do not want to oversize. 2) How do I control my hot water unit heater in my garage? ANSWER: If there is always hot water running through the coil, you may merely use a switch to turn the fan motor on and off when you are using your garage or workshop. Automatic control is preferent over manual control. There are 3 mutual methods for mechanically controlling a hot water unit heater in a garage or workshop: Common Control Sequences The following control sequence descriptions are typical for steam/hot water unit heaters in garage or workshop applications: >>Intermittent Fan Operation – Hot Coil When a room thermostat calls for heat, the motor is energized. Hot water or steam is without disturbance supplied to the unit heater, even when the motor is not running. When the thermostat is satisfied, the motor is de-energized. >>Continuous Fan Operation – Intermittent Hot/Cold Coil When a room thermostat calls for heat, a valve is opened, permitting steam or hot water to enter the unit heater. When the thermostat is satisfied, the valve is closed. The fan runs continuously. >>Intermittent Fan Operation – Intermittent Hot/Cold Coil When a room thermostat calls for heat, the motor is energized. At the same time, a valve is opened permitting steam or hot water to enter the unit heater. An aquastat may be attached to the supply or return piping to prevent fan operation until the coil is adequately heated to keep out of the way of cold air delivery. When the thermostat is satisfied, the valve closes and the motor is de-energized. 3) How do I determine how much heat a hot water unit heater will generate with varying entering hot water temperatures? ANSWER: Hot water unit heaters are also applied with steam. The major hot water unit heater makers rate their capacities using 2 psi steam. For example, a Modine model HSB33 will construct 33,000 BTUs when it is hooked up to 2 PSI steam. Another example: A Sterling model HS120 will give rise to 120,000 BTUs when hooked up to 2 PSI steam. Since you are most likely using hot water in your garage or workshop, you need to know how much heat you will get out of the unit with your specific hot water temperature. Call us. Within minutes we may tell you the precise output for each sized heater beneath any condition. Do not fall for advertisements that assert 290,000 BTUs!. A size 290 unit heater will fabricate 290,000 BTUs ONLY if it is supplied with 2 PSI steam. If you are using 160F water, this same heater will invent 152,000 BTUs, closely half the capacity shown on the advertisement. 4) Can hot water unit heaters be used with outdoor wood furnaces? ANSWER: Absolutely. The coil doesn’t care where the hot water comes from. As long as the water is warmer then the air, the unit heater will transfer heat from the water into the space. 5) What are the dissimilar piping configurations on hot water unit heaters? ANSWER: The most mutual hot water unit heater for a garage or workshop is the horizontal model. Most major makers offer side piping and top and bottom piping arrangements on horizontal units. The side piping connection models grant you to install the heater closer to the ceiling. The top and bottom piping connection models concede you to effortlessly rotate the unit if you need to change the direction it is pointing. 6) What is the best emplacement in my garage or workshop to install my hot water unit heater? ANSWER: The hot water unit heater in your garage or workshop will have to be located in the coldest area, and it must be angled more or less so it blankets warm air throughout the coldest wall. 7) What is the best emplacement to install a wall mounted thermostat in my garage or workshop? ANSWER: The thermostat must be mounted in a emplacement that represents a good intermediate temperature in your garage or workshop. If it is located in a cold spot, it will falsely run the unit heater more then it should. If it is located in an area that receives direct sunlight, it will falsely run the unit heater less then it should. A well insulated interior wall is the best spot for the thermostat. ANSWER: An aquastat gets strapped on to the supply or return hot water pipe. It gets wired in series with the fan motor. The aquastat will only grant the fan to run when there is hot water running through the pipes. This inexpensive device will prevent cold air from circulating all around your garage or workshop when the hot water pipes are cold. 9) What kind of sound may I suppose from a hot water unit heater? ANSWER: While sound is developed anytime fans and motors are applied to move air, Modine unit heaters were designed to denigrate their sound level through the careful selection of motors, fan blades and the design of the air intake opening. The selective information underneath shows typical types of buildings or rooms with a corresponding Sound Class rating. For a unit heater with a given Sound Class rating, when placed in the type of building or room shown below, the sound of the unit heater will be comparatively comparable to the ambient sound level of all sounds within that type of building or room. When purchasing a unit heater, ask for the the sound class rating to be sure you are buying something that will fit your application. Sound Class Ratings Type of Building or Room Sound Class Rating Apartments, Classrooms, Court Rooms, Executive Offices, Hospitals, Libraries, Museums: Class I General Offices, Hotel Dining Rooms, Recreation Rooms, Show Rooms, Small Stores: Class II Bank Lobbies, Grocery Stores, Gymnasiums, Post Offices, Restaurants, Service Stations: Class III Factories, Foundries, Machine Shops, Packing Plants, Shipping Platforms: Class II-VII Forge Shops, Steel Fabricating Shops, Boiler Works: Class VII 10) How may I compare the cost of heating my garage with dissimilar types of garage and workshop heaters? ANSWER: Call us. We will firstborn run a heat load analysis, and then we may run an energy comparison analysis based on your local fuel rates. |
