Homeowners can install tankless water heaters with a little bit of plumbing knowledge. It is important to consult with a professional to make sure the installation is done correctly, as there are many factors that must be considered when installing these types of water heaters. Tankless water heaters have become increasingly popular in recent years because they are more energy-efficient than traditional tank-style water heaters. They also take up less space, so they are a good option for homeowners who have limited storage space. However, they can be more expensive to install than traditional water heaters, so it is important to weigh the pros and cons before making a decision.

Yes. Homeowners can install tankless water heaters, but they should be aware of a few things first. Tankless water heaters require a higher level of expertise to install and often cost more than traditional tank water heaters. Also, it's important to consider the flow rate of the home - tankless water heaters have specific flow rates that need to be considered when selecting a model. If the home's flow rate is too high for the selected model, it won't work properly and could end up costing more in the long run. For these reasons, it's best to consult with a professional before making a decision about installing a tankless water heater.
