SAVE ENERGY! Heat Animals, Birds, People, Objects - not the air around them!

Various sizes and models, with or without temperature controls. Five year limited warranty on all heating elements.


The sun is an example of an infrared heater. It radiates infrared heat waves through space until these rays strike an object, such as planet Earth. The Earth is warmed by the sun's infrared waves. The warmed Earth then gives off heat to heat the air.

Using this same infrared heating principle, we take infrared energy from a man-made heating element, control it with a reflector as light is controlled, and project it to the subject to be heated (animals, birds, people, or objects). This infrared energy is identical to the sun's energy but without the UV tanning rays. It does no heating until it is absorded by the subject underneath the heater. The heated subject then gives off some heat to help heat the surrounding air.


Save Energy!

Why heat the entire building when all you want to do is provide warmth for the animals/birds that are confined in one space. Downgoing infrared rays heat animals, birds, people, objects - not the air around them.

Save Time & Labor!

Kalglo heaters come complete ready to use, similar to a "shop light". No expensive plumbing and installation costs or necessary routine maintenance as with gas heaters.

Save Animals!

Animals love Kalglo heaters for their large heat patterns and lower intensity heat - not focused in one small spot as with heat lamps. Baby animals/chicks will not bunch or pile on top of each other. New born animals usually have no problem finding the warmth under the Kalglo heater. They remain warm, dry and comfortable for better health and faster weight gain.

Safe, Clean Heat!

Kalglo heaters have durable metal sheath heating elements, similar to the elements in an electric oven. No glass tubes or lamps to break and no open flame. Minimal fire hazard! They do not remove oxygen from or put moisture into the air as gas heaters do. They emit no UV (ultra-violet) light.


HS Models

such as 120 volt HS-1215 or 240 volt HS-2420 do not have a switch or built-in control. When plugged into a receptacle the heater will come on full and stay on full until unplugged or turned off. The heater can be turned on/off by a cicuit breaker, a switch controlling the receptacle, or by a separate thermostat such as 120 volt HTP-1 or 240 volt HTH-1 (optional). HS models can be regulated manually by wall mounted electro-mechanical power regulators (duty cycler) such as 120 volt PR-1218RS or 240 volt PR-2436RS, or by electronic dimmer controls such as 120 volt LC-1220 or 240 volt LC-2440. They can also be regulated automatically by a temperature control such as the 120 volt LCEDT-1242 or 240 volt LCEDT-2484.

HS-RS Models

such as 120 volt HS-1215RS or 240 volt HS-2420RS have a built-in manual electro-mechanical power regulator on one end of the heater. It controls the power to the heater by cycling it on and off, so the heater output is a set percentage of its wattage rating. The control has an off position, a HI position for 100% output (on full), and variable number settings from LO to 6 allowing for approximately 23% to 70% output. It is referred to as a manual control because whatever the setting the user has chosen, the heater output will continue at that setting (similar to the heating element controls on an electric range). It is not a thermostat so changes in air temperature have no affect on the output. The heater will not shut off by itself unless it is controlled by a separate thermostat (optional).

MRM Models

such as 120 volt MRM-1215 or 240 volt MRM-2420 have a built-in manual solid-state control on one end of the heater. It controls the heater the same as a dimmer controls a light bulb. MRM models provide a fuller and smoother range of control than the HS-RS models. The output ranges from 0 to 100% and is continuous - not cycled on and off as with the RS control described in the preceding paragraph. The heater will not shut off by itself unless it is controlled by a separate thermostat (optional).

MR Models (Not Available)

such as 120 volt MR-1215 or 240 volt MR-2420 have a built-in solid-state automatic temperature sensing control on one end of the heater. The temperature sensor is on the end of a 4 ft. cord attached to the control. The sensor is suspended below the heater and near the subject to feel what the subject feels. NOTE: MR models are not used where sensors can be chewed off unless the sensor is protected by an expanded metal guard. The control dial on the end of the heater is labeled from L (40 deg. F) to H (100 deg. F) with each line in between representing a 6 degree increment. The set temperature is maintained at the sensor level to within +/- 1/2 degree.


All Kalglo electric radiant infrared heaters have durable metal sheath heating elements. The heating elements carry a 5 year limited warranty against premature burnout and are field replaceable. The heaters come complete with a 7 ft. double insulated cordset with molded grounded plug, 13 ft. of hanging sash chain (to be cut in half for up to 6 1/2 ft. suspension), and hanging hardware consisting of woodscrew hooks and "S" hooks. Close the "S" hooks with pliers for secure hanging. The heaters are typically hung much like a fluorescent light fixture, although wall mounting is possible when an adjustable mounting bracket kit, model AMB-1, is used.
Kalglo heaters are all aluminum so they will not rust when used in high moisture areas. Incidental splashing will not hurt the heaters - it would be similar to a pot boiling over on an electric range. Most Kalglo heaters are intended to be used indoors for utility type purposes. They are most efficient when facing down (not angled to one side) in draft free environments. Windows and exterior doors should be kept closed whenever possible. Optimum distance between heater and subject usually ranges from 2 to 4 ft. All heaters are 5 1/2 in. wide and 5 1/2 in. high and operate on single phase voltage. 240 volt heaters have a NEMA 6-15 plug.
Protective guard grills are usually not needed but are available as an option. Heavy duty chrome plated steel guards easily snap into the heater. One grill for 35 in. models, two grills for 65 in. models. Guard grill is model PGG-30. Order guard grills separately. All Kalglo heaters are made in the USA.

Note: The added infrared will not increase air temperature by the stated amounts, but it will produce the approximate equivalent comfort level directly below the heater (not the entire heat pattern) as if the air temperature were increased by those amounts. The objective is to project infrared heat directly to the subject in order to replace heat from the body as fast as it is lost.
