At Seattle Plumbing & Heating we believe the heating system that is in your Seattle home is much more than a heating is your environment.

We install and maintain many types of heating systems for all of your residential needs. There are many ways to heat your home. This page will cover a few of the most common types of heating units available.

Gas Burning Furnaces

Gas or fuel burning furnaces all work on the same basic principle. The fuel is burned inside an enclosed metal container (generally referred to as a fire box or heat exchanger). The exhaust gases (including carbon monoxide) are vented to the exterior of the building. The burning of the fuel warms the heat exchanger. The heat exchanger, now hot, radiates the heat into the air in the living area. This heated air is circulated by gravity or pumped through the living area with a fan.

Gravity Furnaces

These will usually be found in older Seattle homes. They include floor and wall furnaces and some ducted furnaces that are generally in a basement. The term gravity referrers to the fact that the furnace has no blower to move the heated air around the room. They rely on the fact that heated (less dense) air rises and the cooler (more dense) air falls to circulate the heat. This is not a very efficient way to heat a house and generally will be used as a room heater.

Electric Furnaces

Not the best way to heat your Seattle home due to electricity cost. They can make your electric meter spin like a top. They work like those old bathroom electric coil heaters except that they are enclosed in a box with a blower forcing the cold air across them heating the air for the living area.

Radiant Heat

Radiant heating does not dehumidify the air, so in winter, room humidity is is more ideal. Unlike forced hot air, radiant heat will not dry out breathing passages or furniture. With no fans or blowers, radiant is dust-free, so it's also cleaner. Virus particles, bacteria and pet dander fall to the floor instead of circulating constantly in the air, so your family will stay healthier in winter. Because radiant heating warms the occupants rather than the room, people find they are comfortable at temperature settings several degrees lower than with conventional heating systems. Lower temperature settings mean lower fuel costs.


Space heating energy costs account for roughly 25-30 percent of the total energy costs for a typical commercial building in the Seattle area. High-efficiency boilers can reduce heating costs by 10 percent and in many cases by as much as 20 to 30 percent.

Energy Efficiency BOILERS

In fact, a boiler replacement that reduces gas consumption by 20 percent could save about five to 10 cents per square foot annually.
Boilers are available in two efficiency ranges: around 80 percent for standard conventional boilers, and percentages in the 90s for energy-efficient condensing units.

The dividing line between these efficiency ranges is based on the boilers ability to withstand condensing flue gases. Condensing flue gases, which occur in high-efficiency boilers, require special design considerations to tolerate the corrosive effects of the condensate. Boiler efficiency is defined as how much of the heating value of the fuel is being converted to useful heat.

Condensing boilers absorb more heat from combustion gases, allowing the water vapor to condense and therefore providing increased efficiency. Any hydrocarbon fuel burned in a boiler, whether it is propane, natural gas, or fuel oil, produces water vapor during the combustion process. 
Conventional boilers are non-condensing boilers with materials that cannot tolerate the corrosive properties of condensing flue or stack gases. Conventional boilers operate around 80 percent efficiency, compared to over 90 percent efficiency for condensing efficient boilers. Other factors also influence boiler efficiency, including boiler shell losses, piping losses, and cycling losses.
