This custom-fitted fireplace insert has large glass doors to maximize the view of the fireplace, and a large surface area heat exchange with thermostat-controlled fan-forced air. A fireplace insert [1] is a device that can be inserted into an existing masonry or prefabricated wood fireplace. Fireplace inserts can be fuelled by gas, wood ...
Air convection heating systems have been in use for over a century. Older systems rely on a passive air circulation system where the greater density of cooler air causes it to sink into the furnace area below, through air return registers in the floor, and the lesser density of warmed air causes it to rise in the ductwork; the two forces acting ...
Direct vent fireplaces are extremely efficient compared to a traditional fireplace and can operate at about 85% efficiency. Even a very efficient traditional fireplace only operates at about 15% efficiency. This is because most of the hot air generated by the fire travels up the chimney due to convection.
This is a large and powerful grate heater system that incorporates a large, thermally-conductive heating design along with a multi-blower, high-CFM, forced-air delivery system Another example of a large and powerful grate heater system that incorporate a large, thermally-conductive heating design and a single-blower, high-CFM, forced-air delivery system
A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented .
Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...
The back boiler is typically used with a gravity feed circuit to the hot water cylinder, with a vent or overflow to prevent excess pressure build up.It can also be connected to a series of radiators to provide central heating but usually requires an electrical pump to be fitted to circulate the hot water, some systems can use the gravity circuit to include radiators.
Modern fireplaces vary in heat efficiency, depending on the design. Historically, they were used for heating a dwelling , cooking , and heating water for laundry and domestic uses. A fire is contained in a firebox or fire pit ; a chimney or other flue allows exhaust gas to escape.
