3 Main Reasons Your Heater Doesn’t Generate Hot Water

A water heater plays a vital role in any household to heat water used for showering, washing hands, cooking food, and cleaning the house. Whether a tank or tankless heater, it works by taking cold water from the water supply, making it warm, and pumping it throughout the house. As you open your tap, it provides you with hot water. 

However, did you know that your water heater might no longer generate enough hot water over time? This is likely because it has some issues that need to be fixed. In this article, we will share three major reasons it isn’t releasing ample hot water:

1. High demand for supply

One water heater issue has to do with a high demand for hot water supply in your residential property. Your house may consist of several fixtures and appliances that draw hot water in various areas, such as your kitchen and bathrooms. When these units are turned on simultaneously, it can be quite hard to generate enough water for your needs.

When confronted with this demand problem, the most logical solution is to upgrade or get a new model with a larger capacity. As it can no longer accommodate your family’s needs, you need to have it updated or replaced right away. Keep in mind that its capacity ranges from 8 gallons to 100 gallons. You can opt for one with a 50-gallon or larger tank if you have five or more people in your home.

2. Cold incoming water

A water heater problem can potentially surface if you live in a cold area or during the winter season. As you have to deal with the cold months, your water supply may be impacted as well, producing cold or even frozen water. As a result, the machine has to work harder than usual. If your unit isn’t advanced enough, it may have a hard time doing its job in producing hot water!

When faced with this problem, the first step is to check your thermostat and increase its setting so that it can provide for your household needs. If it’s still not working, you should consider opting for an advanced model with optimal performance and high efficiency.

3. Low water pressure

Another common problem with your water heater is low water pressure. As you may be aware, the pipes, fixtures, and appliances connected to your HVAC system pump the water out. If you have low water pressure, your hot water production may be impacted as well. 

It can be quite hard to fix this problem, as there are various causes of this. The problem may have to do with the main water supply, corroded pipelines, leaking fixtures, or improperly installed units. The best step here is to hire an HVAC specialist––such as the experts at Legacy Heating––who can get to the bottom of the issue and make the necessary fixes.


At this point, you know that the primary reasons your water heater isn’t generating enough hot water for your home. Be wary of the high demand for hot water, extremely cold incoming water, and low water pressure, and follow the plumbing tips and tricks recommended above!
