DIMENSIONS

Selecting Heaters:

Use the calculator below for selecting the quantity and wattage of baseboard heaters you will need in a given area, when using the heaters as a primary heat source (no other heaters present.) Supplementing existing heaters such as a forced air furnace system requires less wattage. A general rule of thumb for primary heating is to use 10 Watts / Square Foot of heat. Example: a 10'x10' room is 100 square feet: (100 x 10 W/Ft2 = 1000 Watts.)

Result:
Keep in mind that this is for an insulated building or room insulated to "electric heating" standards and is an estimation based on average conditions.

SPECIFICATIONS:
The entire heater casing shall be constructed of 6063 extruded aluminum.
Minimum thickness of .100 (12 gauge) aluminum shall be acceptable.
Outlet grill shall cover entire length of air discharge opening and be constructed of steel. All casing and grill construction shall be painted with high quality durable powder coated paint.
The heating element shall be high quality nichrome wire encased in magnesium oxide and sealed in copper tube. The heating element shall be sealed in .312 diameter copper tube and be immersed in heat transfer liquid. Aluminum fins shall be mechanically bonded to the entire heated length of the element for even heat transfer.
Linear automatic thermal limit shall transverse entire heater length of element and protect heater in case of an over-temperature condition.
Optional controls shall be mounted in junction box enclosures at either end of heater. Optional integral thermostat shall be located in junction box with adjustment knob or for tamper-proof operation. Optional disconnect switch shall be mounted in junction
box.
Optional 120 volt or air conditioning receptacle shall be mounted in junction box.
Optional proportional control shall be available with use of R842 relay and T186 microcomputer wall mounted thermostat. The R842 relay shall be mounted in heater junction box.
Optional installation accessories shall include inside and outside corner sections for complete wall perimeter fit.
Profile of corners and grill shall have appearance of heat sections for continuous architectural design.
Corner accessories and heater sections shall be secured by alignment pins for easy alignment of multiple heater applications.

BASEBOARD RELAY CONTROL
Unique relay design permits solid state proportional and integral (PI) temperature control via the room sensor resulting in exceptional temperature control accuracy.
Microcomputer relay designed to substantially reduce long time delays and is not affected by heater ambient temperature conditions.
The new R842 relay, with its sophisticated microcomputer, substantially reduces long time delay and is not affected by ambient temperature conditions. In addition, it can be used with the T186 electronic room sensor, providing PI (proportional and integral) control. It can also be used with any electronic analog signal of 0-10 Volts D.C. from building automation systems or conventional 2-wire low voltage thermostats.  The microcomputer also permits the R842 to achieve a life of greater than 500,000 cycles (typical), even under the high resistive load that this product must handle.


 
ELECTRONIC ROOM SENSOR KIT OPTION
Room Sensor can be directly mounted flush to a vertical surface or standard 2 x 4 electrical mounting enclosure.
