Water Heaters


We all depend on water heaters to heat water for our showers and other running water. Tanked hot water heaters typically last about 10 years before they need serious repair from leaks due to rust caused by mineral/sediment buildup or damaged anode rods. Over time, these leaks can cause water heaters to become too inefficient to be economical; heating water can account for up to 30 percent of utility bills so an efficient water heater is important. Regular maintenance needs to be performed to keep a water heater in good working order, avoid an inconvenient breakdown, extend the life of your unit and reduce your energy bills.

Sediment buildup in water heaters

A banging or knocking noise coming from your water heater could be a sign that you need to have your water heater flushed. The sediment is formed from loose minerals in the water that then settle on the bottom of the heater and form an insulating barrier between the water in the tank and the heating element underneath. This barrier makes it more difficult for the system to produce hot water. We recommend having your hot water heater flushed at least once per year, or once every six months if you live in an area with hard water. You will likely find that you save money on your next utility bill and that your hot water heats up faster after this maintenance is performed. Seattle Furnace plumbers drain the tank and remove sediment as part of our maintenance process.

Anode rod replacement

The anode rod works to pull rust away from the outside of the hot water heater tank toward its position in the middle of the tank. Essentially, the rod is there to prevent rust buildup on the sides of the hot water heater tank and keep the water clean and potable. Anode rods themselves will eventually deteriorate and need to be replaced, leaving your hot water heater vulnerable to rust, corrosion and leaks. Anode rod replacement is a standard part of Seattle Furnace hot water heater maintenance plans.

Test the T&P valve

The T&P valve works to relieve pressure in the system when temperatures get too high or water pressure is threatening to breach the tank. It is an extremely important hot water heater safety feature that needs to work at all times. Thorough inspection and testing of the T&P valve is a standard part of Seattle Furnace hot water heater maintenance plan.

Tankless water heaters

Tankless water heaters have been around for decades in Europe but have only begun to increase in popularity in the United States in recent years. At Seattle Furnace we can install a tankless water heater which can provide the following benefits:

  • Lower water heating costs
  • Better warranties
  • Longer life span
  • Less space consumption
  • Continuous hot waterTankless-Water-Heater-Blue-Springs-MO

Tankless water heaters are typically 30 percent more efficient than standard tanked water heaters. Tankless water heaters offer longer warranty periods; 12-15 years depending on make and model. They also last 15-30 years, which is essentially twice the life span of a tanked water heater. They are about the size of a large back pack so you can put them almost anywhere. Best of all, you will never run out of hot water! One of the brands we carry says that you can run up to five taps at the same time (great if you have teenagers)!

Don’t wait to schedule water heater maintenance until you are faced with a breakdown. At Seattle Furnace we can repair and maintain your water heater, replace your water heater with electric, gas or tankless options and we can even relocate your water heater.
