How to Winterize a Furnace and Water Heater

Winterizing your home is important to help keep the place running efficiently. You don’t want a water heater or electric heater using so much energy that it increases your bill during those dreadful months from January-March. The same thing could be said for using so much A/C during the summertime. Whether you have a furnace or a water heater that needs some repairs, it’s in your best interest to make the investment to save you time and money later. Here’s how to winterize your furnace and water heater. 

Shutting Down Your Furnace

Let’s say you have a boiler and you may need a plumber to help you winterize it. The key is putting antifreeze in the system or draining it completely. You may need assistance because this is a pretty complicated task. In most cases, it’s wise to call a specialist in case you don’t have the knowledge of going through this procedure. A good specialist not only will help you fix your issue but explain what’s wrong during the process if you need any inquiries addressed.  If your furnace is coming from an electric source,  turn off the switch. Whether you use propane or natural gas, you can actually shut this off from the outside.. Make sure you also find the right valve and turn it off. Please drain all the water from your humidifier as well as cleaned or replace your filter.

Fixing the Water Heater

One of the most important things you need to do is check the TPR valve (temperature relief valve) for corroding and leaking.  Drain this area completely because corrosion is poison getting into the valves that you may breathe through pipes. If you have an electrical or gas water heater, please be sure to turn them off for safety reasons. Some homes don’t have a sump pump, but those should be turned off as well if they are present.

Should You Pressurize the System?

Pressurize the system after closing the valves inside your house and opening the ones outside. Turn on your compressor. Two key things to note if you notice there’s no pressure coming out: you have an open valve or a broken pipe.  Your system is naturally charged with air, which makes draining your water heater less complicated. The air has a process of reaching the water line, rising to the tip of the tank, and pushing out the water.  There’s a lot of hot water in your tank, so make sure you let it cool off after it drains before you touch it. The next step is to check the faucets to ensure that air comes out. If there is a lot of corrosion, a lot of your water gets out through evaporation. This could be the main reason why you’re getting a higher heating bill.  If your system is under control, the water may get hot but it shouldn’t boil and evaporate. These are just a few steps to help you winterize your home for a furnace and a water heater.
