If you live in a northern climate it is essential that your home has a clean, energy-efficient, and well-maintained hot water system. Two main types of hot water systems are available, traditional tanks and tankless – you can read more about the difference in our prior blog post here. If you’re in need of hot water tank repair Calgary, Harper Plumbing is always ready to help – reach out to us anytime for reliable service.
Hot water tanks and systems have moved beyond the simple comfort and convenience of having available hot water for all your daily tasks such as washing dishes, laundry, or taking a shower. Today’s hot water tanks can also have side tappings, or ports, that allow for radiant in-floor heating systems to be connected to the tank. This means today’s hot water tanks can be more than a simple device providing hot water, in some homes they can also be used as part of the system to provide a home’s heating.
Regardless of how you use a hot water tank in your home, obviously, no one wants to find themselves suddenly without hot water or discover a pool of water from a leaking tank. Wondering how your system stacks up? We have outlined some helpful tips and things to think about when evaluating your current system.
- Check the age of your hot water tank. Look for a large white and black sticker for this information, this sticker also called the rating plate, has important information related to your tank, such as model, serial number, age and size. In many Canadian cities as a result of our hard water your tank should typically last 8 – 12 years. If your tank is nearing the end of this range then it might be time to think about replacing or installing a water detection device to alert you in case a water leak occurs such as single-use water alarms in the area, or a Flo by Moen system on your main water valve. While a Flo by Moen system is a large investment in your home, it will not only detect leaks stemming from your hot water tank but also other household fixtures and pipes and automatically shut off the water main when triggered.
- Have a listen to your tank. Do you hear any strange sounds such as popping, knocking, or rumbling? This could be a sign of sediment buildup and could lead to reduced efficiency and even damage to your tank.
- Have you noticed inconsistent hot water supply or fluctuating temperatures? Is the hot water taking longer to reach the tap than it used to? If so your tank may be losing efficiency and nearing the end of life.
- Check for corrosion on the outside of your tank. Look at the valves and hoses running into your tank, do you notice any white crusty buildup on them? This corrosion could be a sign of a small leak.
- Does your water appear discoloured or rusty at times? You may also notice a change in your water’s taste. The change in appearance or taste is also another indication that your tank is nearing the end of life and will need to be replaced.
Replacing your hot water system with a new tank will ensure the most energy-efficient service. Modern tanks also have advanced safety mechanisms and are better equipped to prevent leaks and overheating. If you are in the Calgary area, Harper’s Plumbing is here to help you evaluate your current system and find the most appropriate replacement when necessary.
