Small Electric Water Heater Buyer's Guide
Written by Ryanne BrownIntroduction
Small electric water heaters are a great way to heat water quickly and efficiently. They come in a variety of sizes and types, making them a great option for both residential and commercial applications. When choosing a small electric water heater, there are several factors to consider, including size, efficiency, installation, and cost. This buying guide will help you make an informed decision when purchasing a small electric water heater.
Size and Capacity
Small electric water heaters come in a variety of sizes, from units designed to heat a single sink to those that can supply hot water to an entire home. The size of the unit you choose will depend on the amount of hot water you need, as well as the layout of your plumbing system. Make sure to measure your available space, as well as the water pressure and flow rate in your home, before purchasing a small electric water heater.
Types of Small Electric Water Heaters
There are several types of small electric water heaters available, including tankless, point-of-use, and storage tank models. Tankless models are the most efficient and can provide hot water on demand, but they require a higher initial investment. Point-of-use models are smaller and require less installation, but they may not provide enough hot water for multiple fixtures. Storage tank models are the most common and are available in a variety of sizes, but they can be inefficient and require regular maintenance.
Efficiency
When choosing a small electric water heater, it is important to consider the energy efficiency of the unit. Look for models with energy-saving features, such as insulated tanks, timers, and thermostats. These features can help reduce energy consumption and lower your utility bills over time.
Installation
Installing a small electric water heater can be a complex process, depending on the type and size of the unit you choose. Most models require professional installation, so be sure to factor in the cost of installation when making your purchase. Be sure to research local codes and regulations as well, as certain models may not be allowed in certain areas.
Cost
The cost of a small electric water heater can vary depending on the type, size, and efficiency of the unit. Tankless models tend to be more expensive upfront, but they can save you money in the long run due to their high efficiency. Point-of-use models are generally the least expensive, while storage tank models usually cost somewhere in between. Be sure to compare prices and features before making your purchase.
