Steam boilers: These are not as common in homes today, but they do still exist. A heat exchanger boils the water and sends it through a system of pipes using pressure, and gravity brings cooled water back to the boiler. Hot water boiler: Like the steam boiler
Get priceTypical Energy Balance of a Boiler/Heater (before improvements) Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler.

For rural areas with limited access to natural gas, oil-fired boilers and furnaces are an alternative. Oil furnaces are cheaper than their natural-gas peers, but gas models are slightly more efficient on
