Abstract: A system for mounting a heater to structural members having a predetermined spacing includes a first mounting bracket having first and second mounting locations. The first and second mounting locations are spaced apart by a first integer multiple of the predetermined spacing. The system also includes a second mounting bracket having third and fourth mounting locations. The third and fourth mounting locations re spaced apart by the first integer multiple of the predetermined spacing. The system further includes a plurality of attachment points on the heater for attaching the first and second mounting brackets to the heater. The plurality of attachment points is arranged to locate the first, second, third, and fourth mounting locations in a mounting plane, with both the first and the third mounting locations and the second and the fourth mounting locations being spaced apart by a second integer multiple of the predetermined spacing.

Abstract: A ventilation fan unit with a heater, including: a frame with an opening provided at the underside of the frame; a cover having an air outlet and an air inlet provided at the opening of the frame; a snail-shaped casing with an air exit provided in the frame; a circulating fan enclosed in the snail-shaped casing; and a heating portion including a spiral heater mounted at the air exit of the snail-shaped casing, wherein the heating portion is communicated with the circulating fan through the air exit, wherein an axis of a spiral shape of the heater is in parallel with a rotation axis of the circulating fan, wherein the rotation axis of the circulating fan is located obliquely above the axis of the spiral shape of the heater.

Abstract: A fan heater includes a main body having a suction port provided at a lower side thereof and a hot-air outlet port provided at an upper side thereof, blower provided below the hot-air outlet port within the main body, a plurality of heating cartridge holders provided on in the main body, a plurality of heating cartridges, each of the heating cartridges configured to be secured to each of the heating cartridge holders and to heat air flowing into the main body through the suction port, a carbon fiber ribbon provided in each of the heating cartridges, and an interior housing that guides the air introduced through the suction port to the hot-air outlet port.

Abstract: An electrical heating apparatus includes a primary heating stage heat pump, a secondary heating stage resistance heating circuit having a plurality of heating elements, an adaptive resistance heat controller and a two-stage thermostat. The adaptive resistance heat controller is connected to the two-stage thermostat heat pump and resistance heating circuit. The adaptive resistance heat controller includes a duty cycle monitor that monitors the duty cycles of the thermostat primary and secondary stages. The controller selectively energizes one or more of the plurality of heating elements in response to changes in the duty cycles so as to provide adaptive heating control to meet actual heating demand while reducing overall peak energy consumption.

Abstract: An apparatus to heat potable water aboard a recreational marine watercraft includes a metal enclosure that sits atop one burner of a conventional galley stove powered separately from the engine and the source of AC power. Potable water is circulated through a tubing unit mounted within the enclosure by a pump operated by a low DC voltage. The heated potable water is then transferred back to the potable water holding tank through a check valve which prevents reversed flow of the heated water. This provides a boater with the ability to maintain a source of hot water while away from shore power or while the engine is turned off. The top of the enclosure is partially open to allow use of the burner for cooking, or boiling water as needed with the cooking vessel being placed atop of the enclosure.

Abstract: A method and a configuration for heating buildings has an infrared heating system containing a radiant tube disposed in a first building, particularly in a hall, to which a gas heated by a furnace is supplied at a first end. A second end of the radiant tube is in a flow connection with a heat exchanger that is subjected to the heated gas after the gas leaves the radiant tube. A radiator or tap water dispenser is disposed in a second building that is connected to the heat exchanger via lines in order to emit the thermal energy absorbed by the heat exchanger in the second building in the form of convection heat or heated tap water.

Abstract: The heater characterized by the fact, that is being determined by at least one segment (1) which in side-view resembles letter “L” in upside-down position and each segment (1) is created from the housing, where heating element is fixed, at the same time the housing improvingly consists of parietal part (2) as well as upper part (3). Parietal part (2) of the housing comprises full partition, whereas the upper part (3) of the housing is equipped with slits (6, 7), improvingly rectangular in shape.

Abstract: A supplementary thermal system controller for assisting a main system controller in retaining a desired temperature rise by monitoring the temperature in the return duct, wherein the supplemental controller comprises a microcontroller for reading and processing return duct temperature measurements, a signal conditioner circuit for preparing temperature related signals for processing by the microcontroller, processor readable medium of program code for determining the rate of temperature change in the return duct and providing control signals based on the rate of temperature change, and a supplemental thermal source driver for controlling a supplemental thermal source, such as electrical resistance heating elements, to cause the assisting temperature source to increase or decrease its thermal output.

Abstract: A method of combining electric heating with a wood-heated masonry furnace is provided. The masonry furnace has an outer jacket (1) and at least one fire chest (5, 6) arranged therewithin for burning the wood. Cheek conduits (8) between the outer surface of the fire chest and the inner surface of the outer jacket, are provided. The conduits are connected to the fire chest (5, 6) at one end and to a flue (9) at the opposite end. At least one electric resistor element (13) is installed inside the furnace. In order that electrical heating could be easily combined with any existing masonry furnace, holes (14) are drilled in the fire cover (10) of the furnace and the at least one resistor element (13) is arranged to hang from the fire cover (10) in the air space (8, 16) inside the furnace.
