What to consider to buy a tankless hot water heater
A tankless hot water heater is a great investment for your home. Not only do they save you money on your energy bill, but they also last longer than traditional hot water tanks. If you're thinking about buying a tankless water heater, there are some things you need to know first.
In this blog post, we will discuss the different types of tankless water heaters available, as well as the pros and cons of each one. We will also provide tips on how to choose the right model for your needs.
1. The type of fuel it uses
One important factor to consider when buying a tankless water heater is the type of fuel it uses. The most common types are electric, natural gas, and propane.
Electric tankless heaters are more energy efficient and have lower operating costs, but they may not be able to meet the hot water demands of larger households. Natural gas and propane tankless heaters have higher energy costs, but they can handle the hot water needs of larger households.
2. The size and flow rate of the tankless water heater
Another important consideration is the size and flow rate of the tankless water heater. The size should be based on the number of bathrooms and appliances that need hot water in your home. The flow rate determines how quickly the unit can heat the water.
3. The warranty and customer service of the manufacturer
In addition to these factors, it's also important to look at the warranty and customer service of the manufacturer. A longer warranty and good customer service can provide peace of mind and make any potential issues easier to handle.
