Conservation: Home Heating

Space heating represents the single largest energy consumer in the typical Seattle home. It doesn't matter if you live in a house or an apartment. It doesn't matter how many people live in your home. It doesn't matter what appliances you own. It doesn't matter how many loads of laundry you wash. It doesn't even matter whether or not you have a spa or a sauna. Heating your home will probably use at least half the total energy of your household. For an average single-family home with electric heat that means at least 9,000 kWh* per year or almost $800 per year at current rates.

The amount of heat you use also depends on how cold it is outside. The difference between a constant indoor temperature and the daily outdoor temperature is called heating degree days. City Light has a degree day chart that shows you heating degrees for each month of the year.

Therefore it makes sense to try to understand your heating system and how to get the most comfort for the least money from it. We hope the information posted here will prove useful to you. If you have any comments or questions, please inquire via email.

Almost all heating systems can be put into two different categories: central systems and zonal systems. In a central system the heat is produced in a single, central location like a furnace or a heat pump. The heat produced is then transferred throughout the home using hot air or hot water as the medium. Zonal systems produce heat in several locations throughout the home, generally in individual rooms. Electric baseboard heaters are the most common example of zonal systems in Seattle. Each of these systems has advantages and disadvantages.

*kWh: Your electric meter measures kilowatt-hours, and your City Light bill is based on your kWh usage.
