3 Things to Know About a Tankless Water Heater

During home renovations and remodelling, one upgrade you may be considering is in your water heater. One popular option is to switch to a tankless water heater. But before you settle on this switch as an answer to your home water needs, you need to know a few things about tankless water heaters. These key points can help you better understand what this option offers and what may be an issue for your specific home.


1. Flow Rate

One of the first benefits that many homeowners consider with tankless systems is the on-demand water. Ideally, you will have hot water on demand for as long as you want it. That’s because water is heated as needed rather than held in a tank and kept hot until you are ready to use it. But the limitation with this on-demand benefit is the flow rate.

The flow rate of the water may be weaker if you don't have the right size tankless system. If you have a large house with lots of water demands, then a larger system will be necessary. Fortunately, most homes can handle larger systems. You should consider a larger one if you have multiple water uses, such as dishwashers and showers, that may be running at the same time.


2. Cold Water Issues

Another common myth is that tankless water systems deliver hot water on demand with no break. In other words, you might assume that if you take a shower, you will have immediate hot water with no wait time and cold water will not sneak in. This assumption is somewhat true, but cold water may show up in some instances. The water is not exactly hot on demand.

The hot water may take a few seconds depending on how far the water has to travel to your location. For example, you might feel some lukewarm or cold water as the water travels to a second-story bathroom rather than to the room next to the tankless system. You may also have cold water for a few seconds if some warm or hot water was trapped in the pipes when the water valve was last turned off.


3. Weather Considerations

Every home appliance, both indoors and outdoors, has maintenance tasks for different weather conditions. The same is true with a tankless water system. For example, during the winter months, you will need to totally drain the tankless system to ensure no water is left in the pipes or system that can freeze. If water freezes, it could cause the need for a full replacement of the tankless system and plumbing.
