Quick System Sizing...
Design Guidelines
1) Determine panel size by selecting a balanced combination of Enerjoy Peopleheaters to cover 10% of the ceiling surface.
2) Design symmetrical heatmodule placement in the same way you locate lights to illuminate a room, recognizing areas of high heat loss and special comfort areas.
3) Take full advantage of the broad dispersion of radiant energy emanating at a
80° angle from the heatmodule surface. It is all right to over size[1] by using identical heatmodules to attain symmetry even though the sizing chart calls for unequal or smaller units.
Rules of Thumb:1) Select a geometrically pleasing design, while allowing a 2' to 4' setoff[2] from exterior walls and figuring approximately two times the setoff distance between Peopleheaters. 2) Use the following general specifications to determine watts per square foot (W/SF) of room area: Bath areas: 7 W/SF; Living room or corner offices: 6 W/SF; Dens, offices, dining rooms or corner bedrooms: 5W/SF; Kitchens or middle bedrooms: 4 W/SF. Above 7,000 degree days add 1 W/SF.
[1]The sizing increase or decrease determines cycle frequency- how quick the thermostat setpoint is satisfied.
[2]There is no set off restriction. Unnecessary heat loss is minimized

| Wiring note: Existing 20 amp 120 volt lighting circuits may serve Enerjoy I Heatmodules. |
| Insulation note: Insulate floor above basement or crawlspace. |
Additional Guidelines:
Supplemental heating: basements and super-insulated houses- Use 1-24RP for each 100 sq. ft. of space--approx. 3-4 W/SF.
Cathedral ceilings or 10' ceilings:
For 12' peak (avg. 10') increase heat panel area by 25%. Ex.- Use 28RP instead of 26RP.
For 16' peak (avg. 12') increase heat panel size by 50%.
Split Levelbuildings- Add one watt per square foot.
Fireplaces, sliders or skylights- Add one watt per square foot.

BUILDING SPECS: Wall: R-19; Floor: R-19; Ceiling: R-38; Glass: R-2 (above graphs assume window size of 3’x4’ & Sliding glass doors of 6’x6’8”); Air changes per hour: 0.25.
CHART USAGE: 1) Compute window percentage of outside wall; 2) Find intersection with Design Temperature; 3) Select ENERJOY Module(s) to meet wattage.
PLACEMENT: Parallel to and centered with 2’ offset from outside wall; second panel, if required, will be aligned with the first and separated approximately 4’ to 6’, or the distance necessary to achieve geometric layout balance
