Tankless Water Heater Buyer’s Guide

Tankless or ‘on-demand’ water heaters are a more energy efficient solution to the problems posed by old fashioned storage tank heaters. The water heaters of the past were ideal in their day, but in modern times we need a more practical solution.

Rather than store heated water in a giant tank, tankless heaters heat the water as and when you need it. This ‘on demand’ function makes them more energy efficient, and means you can save money on your energy bills each month.

One of main categories you will see mentioned about these units is the maximum water flow rate. This number should be one of your key considerations when browsing on-demand heaters. Measured in gallons per minute (GPM), this is the amount of hot water that will be available to your household at a particular time. The top models will give as much as 10 GPM, which will be enough for even the biggest of families. Anyway, more of that later…

Tankless water heaters were first readily available around 10 years ago. However, in their infancy they were unreliable as technology wasn’t quite ready for them. These days technology has turned them into machines of efficiency and they have improved in every area.

Improvements in Modern Day Tankless Water Heaters

  • Modern day water heaters retail at much less intimidating prices than those of 10 years ago.
  • They are easier to install, as they have more practical designs which makes connecting to existing gas lines much more straight forward.
  • There are no longer problems with inconsistent water temperatures. Manufacturers have solved this problem in innovative ways by introducing buffer tanks and recirculation pumps.
  • They are more reliable and much easier to maintain.

How Do They Work?

Gas and electric tankless water heaters work in the same way as standard water heaters that have tanks. The difference is that they are able to heat the water much more quickly, and are able to work only when needed. This means they don’t need a storage tank, and don’t use up the energy needed during standby operation.

When a hot water tap or appliance that draws hot water is turned on in the home, cold water is drawn into the water heater. The unit senses the flow of water and activates the burner. This in turn warms the heat exchanger (the part that heats the water). The heat exchanger is surrounded by the incoming cold water, which is then heated to the desired temperature, ready to travel on to the desired location. Since these units only heat water as it is required, they are much more efficient than conventional water heaters.

Some Energy Star certified tankless hot water heaters use a further heat exchanger. This allows them to use 9 % less energy than regular units. The second exchanger takes heat from the combustion gas, and condenses (cools) it. This means that the exhausted gas is much cooler than regular systems. Generally speaking, if the exhaust gases are cooler then it means the system has been more efficient and less energy has been wasted.

Before You Buy: Checklist

1. Estimate the capacity that you’ll need.

This is really important with a tankless system. If you choose a model that can’t keep up with demand, then you won’t get any hot water.

While capacities of storage water heaters are defined as the number of gallons that fit into the tank, whole house tankless water heaters are measured in a different way. So how is the capacity of a water heater measured? Well, tankless hot water heaters are defined by the amount of hot water they produce in one minute. This gallons per minute (GPM) rating can vary from about 2-13 through different manufacturers. To estimate the type of capacity that you will need, you should imagine peak water usage times in the home. Here are some average numbers to help you estimate your peak water usage:

Reason For UseGallons per Minute (GPM)
Clothes Washer3.3
Shower and Bathtub2.5
Kitchen and Bathroom Sink2.2
Dishwasher1.3

If for example, you have two bathrooms and there are times when people will be showering simultaneously, then a model with a GPM rating of at least 4 would be desirable. However, a one bedroom home could suffice with something as low as 3 GPM. These GPM ratings also depend on the temperature of the incoming water. If you live in a cold area then expect the stated GPM value to be lower.

This isn’t the only number that you should be checking though. Each model has its own sizing chart. This includes information about the flow rate, the number of hot water fixtures in a home, and the effect of temperature rise. The sizing chart displays how a water heater performs in each situation, so that you can make sure you get the right sized model for your home.

Check out the sizing chart for the Stiebel Eltron Tempra range here.

2. Check out the warranty. 

The longer warranty models will probably be more expensive, but for something that is going to get used as much as this, it might well be worth it. Warranties can run for over 10 years with some models. Be aware that most of the warranties depend on the unit being installed by a professional.

3. Think about where you will install it. 

The units themselves are very small and compact. However, some will need to be installed near a gas supply, and some models will need ventilation for combustion gases. Changing to a tankless system from one that uses a tank will free up some valuable space anyway.

4. Make sure your home is a good fit for a tankless heater. If your current water heater is electric and you don’t have the capability to provide propane or gas, then you probably shouldn’t go for a tankless system. You would need to increase the capacity of your electrical system by too much for it to be worthwhile.

Also, these types of heater don’t fit extremely cold water supplies. The heater’s capacity depends on the incoming water temperature. The colder your water the less GPM of hot water you will get. This is because it has to heat the water more and for longer because its cold. Choose your tankless water heater based on the winter water temperature in your area. This caters for the worst case scenario. The output will be much better through the other three seasons.

Why Get A Tankless Water Heater Instead of A Regular One?

They have many benefits over standard water heaters. Let’s have a look at why they are a better fit for your home.

  • They are more energy efficient. They only heat water when it is needed.
    • Water heaters are said to account for around 25% of all energy consumed in a household. Improving the energy efficiency of this unit will make a big difference to consumption.
  • They are cheaper to run because of this.
  • They won’t run out of water. A standard water heater only has as much hot water as is inside the tank.
  • They take up less space. A residential tankless heater is only around the size of a small suitcase.

The Pros and Cons of Tankless Water Heaters

Pros

  1. More energy efficient – As these systems don’t have to maintain the water at a constant temperature, they use less energy. They work on an ‘on-demand’ basis. This means they use just the right amount of energy to heat the amount of water that is needed. Energy is not wasted keeping a tank hot. They also provide a more consistent temperature of water, meaning that scolding hot water doesn’t come out of the faucet. This again saves energy.
  2. Cheaper to run – A by product of being more energy efficient is that they will save you money on your energy bills too. Water heaters can account for around 25% of energy bills, so significant monthly savings can be made.
  3. Space saving – Traditional water heaters with tanks can be huge. These units don’t have a tank so require very little space. Even the larger units are only around the size of a medium suitcase.
  4. Won’t run out of hot water – These units heat the water as and when it is needed. This means they are not limited by the size of a hot water tank. As long as you have a model that has a water flow rate big enough to keep up with demand, then you won’t run out of hot water.

Cons

  1. Not great in cold weather – If your incoming water is likely to get seriously cold, then maybe a tankless system isn’t a good fit. This would require a lot of energy to get the water hot and would slow down the water flow rate. You could get around this problem by getting a system with a really large flow rate.
  2. Start-up cost – These system are generally more expensive than their traditional counterparts. They may also require some extra work upon installation, if you need to upgrade existing gas or electrical infrastructure. In the long run you are likely to save money and you will recoup this cost.
  3. Not a good fit for really large households – I’m talking +4 bathrooms in size. This would push the limits of the high capacity systems, and might even need multiple systems to cope.

How Do I Maintain a Tankless Water Heater?

These devices contain a heating exchanger (heating coil) which is surrounded by water when it is in operation. Water contains minerals like calcium and magnesium which create limescale that binds to the heating element and walls. As the heater gets very hot very quickly it will “bake” the minerals to the inside of the unit. This limescale will reduce the efficiency of your water heater and can even break it. Therefore, you must perform proper maintenance on it. People that live in areas with really hard water (lots of calcium and magnesium) may need to maintain their unit once every year, while people in areas with softer water (or those that have a water softener) might not do this every 4 or 5 years.

Maintaining one of these units is a straight forward job. It will differ very slightly between manufacturers, but generally it is just a matter of rinsing it with undiluted white vinegar. This will remove any limescale or mineral build up on the heating elements.

You can take a look at the basic maintenance procedure with this guide.

FAQs

Will I get instant hot water?

Actually, no you won’t. This is a common misconception about these types of heater. It will heat water instantly on-demand, but it will still need to travel through the plumbing lines. To get instant hot water you need to install a recirculation pump. These are available with many tankless models.

Do I need to upgrade the gas line?

Yes, possibly as they need a bigger gas line. Tankless heaters need more Btus because they use their energy over the period of a few seconds or minutes. A traditional system that uses a tank is able to use energy more steadily over a long period of time. The minimum gas line size is usually 3/4 inch and the size of the gas line upgrade will depend on the model and distance from the gas meter.

So it uses more gas than a traditional system?

No, they use the same Btus. The traditional system heats more steadily, but they both use the same amount of energy to do the same work. The tankless unit will save energy as it has a higher energy efficiency, and will only heat water when it is needed. A system with a tank will waste energy by continuously heating the water to maintain the desired temperature.

Why do some models need electricity and gas?

The gas supply is to heat the water. Most models are operated by digital controls. They use digital monitoring and have an electric ignition.

Will I need a water softener?

No, you don’t need one. However, if you live in an area that has really hard water, then a water softener would help to prolong the life of the water heater. Some kind of water treatment system to prevent scale build up on the water heater would be an advantage.

Will it save me money on my energy bills?

Yes. These systems are more energy efficient because they only heat water when it is needed. Traditional water heaters are lazy when it comes to energy efficiency because they are constantly in operation and use energy. all of the time If you choose a system with a really high energy efficiency ratings or an Energy Star certificate, you are likely to save even more each month.

Do they need regular maintenance?

They should be maintained around once a year. This is a simple job which involves rinsing the system with vinegar to remove limescale from the heating elements. If you have a water softener then this won’t have to be done as often.

How much do they cost?

Tankless water heater prices vary from around $200- $1500. The prices change according to the size/output of the unit, energy efficiency rating, and general features a unit offers. The best tankless hot water heaters offer precise digital controls that let you strike an energy/heat balance that will save you the most money on your bills.
