A Brief Explanation For Cold Weather Durability
It’s no secret that when winter rolls around, Rochester is a cold place to live. And when the thermostat starts falling, your home is going to need to prepare more than just stockpiling blankets and firewood. For many homeowners across the region, one of the key preparations needing to be made before settling in is winterizing their tankless water heater.
Why Is Winterization So Important?
Many warranties for hot water heaters may not include coverage for damages related to cold weather. Because of this, failure to properly prepare your unit can result in less cash in your wallet and more headaches than you can handle.
Luckily enough, winterization of a tankless water heater is a simple ordeal, most commonly requiring all water to be emptied from the pipes inside of the heater. Water allowed to sit in your pipes can freeze, backing up the heater and causing damage or mechanical failure.
Despite the apparent simplicity of winterization, there are several other steps needing to be taken to ensure your heater stays intact.
Step 1: Cut the Power to the Heater, Waiting Until the Water Inside Cools
This may be an obvious step; however it is important to not set yourself up for any unnecessary injuries. Heaters can be powered by electricity or gas, so ensure all precautions are taken to stay safe on the job. In addition, keep in mind the water inside the heater’s inner workings will be extremely hot, so make sure the water is at a manageable temperature before working with it.
Step 2: Shut Off the Main Water Supply
Since there’s no reservoir for the unit, the water is going to keep coming until you shut it off. Instructions for where the heater’s shut off switch is can typically be found in the device’s owner’s manual.
Step 3: Open the Hot and Cold Water Taps On The Unit
This will not only drain all of the water out of the heater’s inner workings, but release a majority of the pressure that will have built up inside the unit. After this is done, disconnect the incoming and outgoing hoses and pipes and set them aside, allowing them to dry out completely.
Step 4: Remove the Water Filter
Commonly referred to as the inlet water filter, its location can be found inside of your heating units owner’s manual. Once you’ve done this, turn an air compressor onto the water filter’s connection. The blowing air should help to rid the heater of any remaining water.
