A very simple method for determining how much total heating wattage you need can be found by calculating the square footage of the room, then multiplying this by 10 watts to produce a baseline wattage requirement. For example, if you are heating a 12-foot x 12-foot bedroom, it will have 144 square feet.
How much hydronic baseboard heater do I need?
Generally, an electric heater should have 10 watts of power for every square foot of living space, and a radiator should put out 20 BTUs per square foot. For example, a 100 square foot room would require at least a 1,000 watt (100 x 10) electric hydronic baseboard heater, or a 2,000 BTU baseboard radiator.
How do you measure baseboard heat?
Measure the length from top corner to top corner of each baseboard heater you plan to cover. Measure from the outside edge of the Left Endcap to the inside corner of the L-Shape. You want the tape measure to touch the opposing wall. Take this gross length and subtract 3 inches.
How do I calculate BTU for hydronic heating?

A typical output of a residential hydronic radiant heating system is within 25-35 BTU per square foot, with 40 BTU being a rare occasion for older homes and buildings with poor insulation. 2. 12W per square foot equals approximately 41 BTU per square foot (optimal heat output with enough backup power).
Are hydronic baseboard heaters worth the money?
Yes. Hydronic wall heaters are more energy-efficient than convection heaters. A hydronic heater provides a more even heat, which means the thermostat won’t cycle on and off as often. … By adding moisture into the air with hydronic baseboards, there’s less dust in circulation throughout the room.
How many BTUs does a baseboard heater put out?
If you run baseboard around the perimeter, you’ll be installing 30 feet of element. Since each linear foot of baseboard puts out about 600 Btu/hr (when the average water temperature is 180 degrees F), your radiator will be pumping about 18,000 Btu/hr into that bedroom.

How are heater covers measured?
Measure The Lengths of Your Baseboard Heaters Each endcap can be slid out to cover a greater length beyond the end of the panel once snapped on. In fact, a pair of endcaps can offer a full 3-1/2″ of additional span to the overall length of coverage on a typical straight heater.
How do you calculate radiant heat?
- Calculate the area to be heated in square meters. Area (m2) = Length (m) x Width (m)
- From the table above, select the factor that most closely matches the building type. Heat load (kW) = Area (m2) x factor.
- Select Activair infrared radiant heaters that match or slightly exceed the required heat load.
How many BTU of heat do you need per square foot?
To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.
What size PEX should I use for radiant heat?
Generally, for residential Radiant Heat Systems we recommend 1/2 Inch PEX Tubing. The PEX Tube size dictates the flow rate that can be achieved and thus the maximum loop length of the pex tube.
How many baseboard heaters do I need per room?
Instructions. As a rule of thumb, assume a room requires 10 watts of electric heating per square foot of room. In other words, a 10×10 room (100 square feet) will require 1,000 watts of electric baseboard heating. This heating can be provided by a single baseboard heater mounted on the wall.
How many linear feet of baseboard do I need?
Divide the total number of inches by 12 to convert from inches to linear feet. For example, if your wall measured 40 inches in length, and you are installing molding on the top and bottom, 40 x 2 = 80 inches. Divide 80 by 12 to get 6.66 linear feet.
Can I remove fins on baseboard heat to reduce the amount of heat?
If you want to permanently reduce the amount of heat transfer from this section of baseboard radiator, depending on the specific design of your baseboards, you might be able to carefully remove the fins from part of some of length of it. This is another way of reducing the heat transfer properties.
How long do hydronic baseboard heaters last?
The life expectancy of hot water baseboard heaters is about 20 years, however, with care they can last much longer.
Is hydronic heating cheaper to run?
Hydronic heating systems are less expensive to run than some other types of heaters. By some calculations, hydronic heating systems are 35 percent more cost effective than running a ducted system.
Are hydronic heaters worth it?
It takes less energy to circulate water than blow hot air so hydronic systems are more energy efficient than air systems. Heat produced by a hydronic system doesn’t get lost while traveling through ductwork. … Radiant floor hydronic systems provide an extra level of comfort by heating the floor and other surfaces.
