Did your shower suddenly go from cozy and comfortable to cold? If you have a tankless water heater, take a look at the possible problems and what you can do about this common plumbing issue.
Why Won't Your Water Heater Work?
There isn't one clear-cut answer to this question. Even though on-demand water heaters are durable, this type of appliance is like any other part of your home—it can fail. Before you can repair the water heater and restore warmth to your next shower, you need to understand the possible problems. These could include:
The average lifespan of an on-demand style water heater is 10 years, according to the International Association of Certified Home Inspectors (InterNACHI). If your appliance is more than a decade old and won't heat your home's water effectively, it's time to consider a replacement.
Are you using the shower while your spouse is filling another tub, the dishwasher is on, and a load of laundry is in the clothes washer? Multiple appliances/fixtures can overload the system and reduce or stop the flow of warm water.
Hard water can cause calcium and magnesium buildup. This can reduce the effectiveness of your tankless appliance.
A blown fuse
An electric water heater requires, as the name implies, electricity. A blown fuse or tripped circuit breaker will stop the appliance from working properly.
Dust, debris, and other objects can block the water heater's exhaust. This potential problem is likely to result in an error message.
Now that you know what some of the top tankless appliance issues are, it's time to move on to the next step and repair your water heater.
How Can You Fix Your Water Heater?
The better question is—who should fix your hot water heater? Whether you're fairly certain you know what the problem is, or you have no idea why your shower is suddenly ice-cold, you need to contact a professional plumber for an accurate diagnosis. A quality plumber:
Has the experience necessary
A professional plumber has years of experience working with tankless appliances. This means the plumber knows what to look for, how to evaluate problems, and the safest way to repair the appliance.
Has the equipment necessary
Do you own a toolbox filled with the plumbing equipment needed to repair your water heater? A plumber does. Don't waste money investing in tools you'll use one time for this job. Instead, leave this repair to a pro.
Has the right parts
Does the repair require more than just tools? The plumber has access to replacement parts or a full replacement water heater.
Before you hire a plumber for your tankless water heater repair needs, ask the contractor if they specialize in this type of appliance. The plumber should have extensive knowledge of on-demand water heaters and carry replacement parts for the model in your home.
