5 Things to Consider Before Installing a Tankless Water Heater

5 Things to Consider Before Installing a Tankless Water Heater

If you seek compactness and performance, a tankless water heater is the right choice for you.  Ever since tankless water heaters became popular, more and more homeowners began to ditch their traditional predecessors.  A tankless water heater offers a variety of benefits, one of which is an uninterrupted supply of hot water. However, installing a tankless water heater is more than merely replacing your previous water heater with a new one.

Here are a few things to consider before installing a tankless water heater.

1. Capacity

Unit capacity is one of the most important factors to consider before installing a tankless water heater. To determine the capacity you require, you need to gather a few important pieces of information. Firstly, you need to add up the flow rates of all the fixtures in your home. The flow rates are measured in gallons per minute (GPM). In some items, such as your toilet, the GPM is clearly mentioned.

Once the flow rates have been determined, you need to figure out the level of heat that is needed to bring your in-coming water temperature to a certain level. Because of a significant amount of math involved, it is better to assign the task to a professional plumbing company.

2. Gas Line Size

Compared to its conventional predecessors, a tankless water heater uses four times more BTUs. Most people believe that a tankless unit needs more gas to function, which is not true. Unlike a traditional water heater, a tankless unit needs an initial kick.  Normally, the size of a gas pipeline for a tankless water heater should be 3-4 inches. If you fail to figure that out, it is better to seek help from a professional plumber. A plumbing professional will guide you on whether or not your gas pipeline needs to be modified.

3. Ventilation Requirements

Unlike a conventional water heater, a tankless unit has different ventilation requirements. This is one of the reasons why it requires special modifications. A tankless water heater can be vented in either of the two ways mentioned below.

·         Power Vent

·         Direct Vent

Power vents use indoor air, while direct vents use air from the outside. Regardless of what kind of ventilation you use, you need to make sure that you have the Grade-3 venting material, which is stainless and corrosion-resistant.

4. Electrical Energy

Even if your tankless unit needs gas to run, you need some form of electrical energy to get your remote and the PC board running. Therefore, you need to make sure you have access to at least 120 volts of electricity. Remember, that your tankless unit will seize to function in the event that power goes out.

5. Location

Two things that hinder the placement of a tankless water heater are ventilation and clearance. For example, a power vent needs indoor air, which is why it should be placed at a location that has adequate flow of air. On the flipside, the direct vent uses air from the outside, so it is alright if it is placed in compact areas like cupboards.
