Years in the plumbing business have shown us many things. Including trends in the breakdown of large home appliances. For instance, water heaters tend to give out more often in the winter months than any other time of year.
Water heaters are under more strain in the winter
For some reason a hot shower when it’s cold outside just feels better. You might notice your family members taking longer, hotter showers.
Water heaters are stored in colder/less insulated areas of our homes.
Attics and garages are not areas in our homes we provide heat to, making the water heater itself work harder throughout the cooler months. Tank water heaters must keep the entire tank hot at all times. Since the water in the tank is kept colder by its surroundings we tend to notice the heater slacking in its duties faster than we would during warmer months.
