Hot Water Not Working
It can be frustrating when your water heater doesn’t provide hot water in the winter, but you can solve the problem by following these suggestions:

Examine your water heater to see if there are any indications of a problem. Make sure the temperature is set appropriately, to about 120 degrees Fahrenheit, and think about flushing it to get rid of any sediment accumulation.
Insulate the Water Heater: You should think about insulating the water heater to help it keep its temperature and cut down on heat loss. To achieve maximum efficiency, wrap the tank with a water heater blanket. This can be especially helpful in regions that aren’t heated in the winter, when the water heater has to work harder to heat the entire house.

Cover exposed pipes with insulation
The risk of frozen pipes is one of the main worries in the winter. In unheated locations like crawl spaces, attics, and basements, look for any exposed pipes. Protect them from the cold by wrapping them in heating tape or pipe insulation. The expense and discomfort of burst pipes can be avoided with this easy action.

Cracks and Leaks in Seals
Look for any openings, cracks, or gaps in your house that can let warm air depart and cold air enter. To keep the cold air out and the warmth inside, caulk or weatherstripping should be used to seal these gaps. This improves energy efficiency in addition to safeguarding your plumbing.
