Buying Guide

There is no soul on earth that can tolerate the feel of cold water in the season of peak cold. However, getting a large water heater with a tank will not only occupy more than half of your bathroom will also take a toll on your budget. The only viable solution in such a case is an electric tankless water heater.

The one best and most lovable feature about a tankless water heater is that it gives a hot water supply without taking up all the space. Therefore, to make sure that you enjoy the perks of your water heater properly, you need to make sure that you are spending your money on the right model. I am sharing a few tips and tricks that will help you locate the best model of electric tankless water heater.

Size Of The Water Heater

The first thing that you need to keep in mind before spending your money on a water heater is the size of the electric tankless water heater. Generally, tankless water heaters come in comparatively smaller sizes than tank heaters. However, there are still models that are bigger than the others.

Keep the space of your bathroom in mind while you are looking for a model. If you are going to mount the water heater in your small kitchen or under the sink in the bathroom, then you need to spend your money on a compact and small model. Otherwise, you will be stuck with a model of electric tankless water heater that is too big for your home.

Construction Material

Another thing that affects the performance of an electric tankless water heater is the material that is used in the manufacturing process. If it comes with a low-quality construction, you will only be able to enjoy hot water showers for a short time. The ideal material for a water heater is copper. Copper has the perks of fire resistance and durability, and it adds those perks to the design. This prolongs the lifespan of the electric tankless water heater.

Another ideal material is stainless steel. Stainless steel brings durability, lightweight and heat resistance to the table. All of these features add more years to the life of an electric tankless water heater. Therefore, when you are out in the market, check the materials used in the manufacturing of the water heater.

Flow Rate

This is a technical feature, and it is highly crucial. The flow rate of an electric tankless water heater is measured in gallons per minute or GPM. The flow rate determines the usage of the electric tankless water heater. If a model comes with 6 GPM, it can be used to run multiple hot showers at the same time.

However, if a model of electric tankless water heater comes with 2 GPM, it will only provide hot water for one shower. If you are purchasing a water heater for a small apartment, then a model with low GPM will be good for you. However, if you are looking for a water heater for a large family, then you need to get one that comes with a higher flow rate.

Points Of Installation

Points of installation are the number of points that a water heater supports or where it can be installed. There are two types of point installations, a single point installation, and a multiple points installation, also known as the whole house installation. If you are getting the water heater for your own bathroom or an office, then a model with a single-point installation will be good for you. However, if you are getting the electric tankless water heater for the whole house, then you need to get a model that supports multiple points installation.

Installation Process

This factor gets neglected at the time of purchase, but it is essential if you are not looking for any extra fatigue. The models that come with a simple and easy installation process are easier to install, so you can effortlessly mount them to your bathroom yourself.

However, if you get yourself a model that has tricky installation, then it will become a source of headache for you, and most likely, you will need the services of an expert electrician. Therefore, if you want to save yourself from the added fatigue and extra money, then get a model that has a simple installation.
