Tankless Water Heater Buying Guide

There are many factors to take into account when deciding which tankless you would need for your home. Firstly you need to assess;

  • How much hot water you will need
  • How much you are willing to pay
  • The price of your bills
  • The number of bathrooms in your house
  • Gallons of hot water per minute

The more expensive larger tankless water heaters will produce many more gallons per minute of hot water, making this type of heater ideal for larger homes. These appliances will perhaps be unnecessary for smaller homes. Therefore the smaller, cheaper models may be more appropriate.

You should also determine what type of instant water heater you would like. The choices you have are electric, natural gas or liquid propane. All have their advantages. Electric heaters are cheaper to buy, but this will increase your heating bills. However, natural gas and propane water heaters are more expensive to buy up front but will save you more money on your gas bills in the long term.

Buying Tips

When purchasing a standalone water heater that produces instant, on-demand hot water, make sure you do plenty of research before committing to the buy. The most important things to look for are:

  • Durability
  • Gallons per minutes
  • Cost
  • Warranty

Taking all these into account will help set you on the right path to purchase the tankless device that your home needs.


Tankless Water Heater Benefits

Tankless water heater becomes the more effective variant, and it does bring a lot of technological improvement over the traditional type. It does offer well-appreciated benefits especially from the standpoints of efficiency, space-saving, and ease of use.

1. Never Run Out of Hot Water

The main idea of a tankless water heater is that the unit doesn’t have to store gallons of water in any tank. Anytime you need a flow of hot water; the appliance will speedily heat up water from any available source and distribute it to you. In other words, it only needs power when the faucet is turned on.

2. More Efficient

With no tank to store water, the appliance does not need to heat it when not in use. A tankless water heater can be powered by either propane gas or electricity, but the appliance will only use the power when you switch it on. As a result, you never waste energy on hot water that you are not currently using.

3. Take up Less Space

The absence of tank greatly reduces the overall dimensions of a water heater. A tank that can store up to 60 gallons of water is considerably big, but you will not have it in a tankless variant. The dimension of a tankless water heater is comparable to a suitcase.

4. Longer Lifespan

The typical lifespan of a tankless water heater is about 20 years. In contrast, the functional life of its tank-equipped counterparts is only about 13 years. Considering the energy efficiency feature and space-saving aspect, you can save a lot of money in the long run.


Tankless Water Heater Drawbacks

Even the best tankless water heater has its drawbacks. Putting aside the manufacturing defects, all tankless water heaters from any brand share the same disadvantages. Some important things you should know before deciding to make a purchase are listed below.

1. Expensive

You should expect to pay at least $1,000 for a good tankless water heater. Of course, the idea is that you pay more upfront, but the energy saving mechanism and durability of the appliance will make it more economical after years of usage. It does not change the fact that the price tag difference is huge, which can be a deal breaker for some people.

2. Higher BTU Requirement

A conventional water heater powered by propane or gas requires 30,000 to 50,000 British thermal unit (BTU) to operate properly. On the other hand, the tankless variant probably uses 150,000 to 200,000 BTU to do the same job. If you want to purchase electric-powered unit instead, please make sure your electrical system has enough supply of power.

3. Limited Water Storage

A tankless heater can only supply a limited volume depending on product specification. When used simultaneously for some hot showers, the water temperature can drop, and the flow rate will be reduced accordingly.

4. Additional Costs for Stainless Steel Tubing

Special venting is required to install a tankless water heater. In some cases, the warranty void if the installation is faulty or not done by professionals. A stainless steel tubing to accommodate the high-powered heater/burner will significantly add the upfront cost.

What to look for in a Tankless Water Heater

There are some important considerations to put into account about the tankless water heater. To make sure you purchase the right thing for your needs and that your money is well spent, please consider below aspects.

1. Power Source

There are two power configurations available for a tankless heater including electric and propane or gas. For those who are replacing a storage tank water heater, it is best to purchase one that uses the same source of power. You don’t have to install an entirely different plumbing system, so you may only need to replace the venting or tubing materials.

2. Flow Rate

The Bigger flow rate is required if many people in the house use hot water. A flow rate of at least 6 gallons per minute should be good to supply hot water for 3 or 4 hot showers simultaneously. The best tankless water heater is not necessarily one with the highest flow rate, but one that is suitable for your family’s need.

3. Dimensions

Dimensions can greatly affect ventilation requirements or the plumbing connected to it. This is important especially if you are upgrading to a larger unit. Nonetheless, there are many products with small dimensions so it should not be difficult for you to choose.

4. Certification

Water heater with Energy Star, WaterSense, or UL Listed certification means the product is properly tested and considered safe for usage and environment. Energy Star and WaterSense testing focus on energy and water efficiency, while UL emphasizes on safety risks.

5. Warranty

Longer warranty usually comes with a higher price tag as well. Warranty coverage typically lasts for up to 12 years, but some manufacturers even offer a lifetime warranty. Long warranty period usually means better quality, so choose an only product that comes with the longest warranty period available.

Conclusion

You should choose a water heater depending on your personal preferences and needs. Any best tankless water heater should be one that’s easy to install and connect to your existing power plumbing system. The warranty that comes with the product must also properly cover heat exchanger, other parts, and manufacturing defects for a considerable period.
