In a residential setting, an electric boiler is often used as a backup to a house's heating system. During the colder months, heating and hot water is used more frequently. This type of boiler will provide additional heating and hot water to a home. [3] Some types of boilers aren't used for heating, but for other purposes.
The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...
The energy cost of heating is one of the main costs of operating a building in a cold climate. Some central heating plants can switch fuels for reasons of economy and convenience; for example, a home owner may install a wood-fired furnace with electrical backup for occasional unattended operation.
heat-recovery boiler: a boiler without its own furnace, used to recover heat from some earlier process, such as a large marine Diesel engine or an industrial furnace. [19] Hornsby boiler: a form of bundled-tube water-tube boiler. [14] Huber boiler: a return-tube boiler used in the Huber company's traction engines. haystack boiler
British Gas (trading as Scottish Gas in Scotland [2] [3] [4]) is an energy and home services provider in the United Kingdom. It is the trading name of British Gas Services Limited and British Gas New Heating Limited, both subsidiaries of Centrica . [ 5 ]
Water from the system or holding tank is then run over or near this hot element in a pipe or tank, heating the water to a suitable temperature, then making the water hot enough to boil and become saturated steam, [1] at which point the saturated steam is transported to wherever it is needed via the steam pipes that exit the body of the electric ...
Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, [3] compared to 70%–80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.
The required steam, water, fuel, and electrical connections can be made rapidly. These boilers are inexpensive to operate because their automatic burner management system doesn’t require continuous supervision and they have low scheduled maintenance costs. [1] A great cost-saving for package boilers is their reduced need for draughting.
