Best Tankless Water Heaters


Why use a tankless water heater?

Well, firstly you get instant, on-demand hot water.

Secondly, a tankless water heater can save up to 50% on your water heating costs compared to a standard water heater.A normal storage-tank type heater keeps the temperature in a tank at around 120 – 140 degrees. Obviously, heat is lost over time even when no water is drawn. Walls of tank lose heat, and pipes lose heat.

There’s gas and electric versions available. Did you know conventional heaters heat water up to a temperature way to use… so cold water must be added! Is that a waste of energy?

Tankless water heaters are rated by the maximum flow rate at which the desired temperature rise is met. Special features may allow the user to set the water delivery temperature. Efficiency is higher than an equivalent tank type water heater because standby losses are virtually eliminated.

Electric tankless water heaters require a relatively high electric power draw because water must be heated quickly to the desired temperature. Residential gas models are available that can heat more than five gallons per minute by 60F, generally more than enough for two showers to be run simultaneously. Whole house electric water units typically have a capacity closer to three gallons per minute. In Toronto Oakville Mississauga Etobicoke tankless water heaters installed.

Tankless Gas Water Heater

Tankless gas water heaters have a gas, or propane heating device that is activated by the flow of the water. Once started, the water heater provides a steady supply of hot water.

Gas tankless water heaters usually have larger capacities than the electric tankless water heaters.

What we liked

The Stiebel Eltron Tempra is a unique product in that customers either loved it or hated it – there were very few people who were undecided as to the merits of this machine. Here is just a small sampling of what the commenters had to say.

Many people had nothing but good things to say about the Stiebel Eltron Tempra when it was used in its correct application. When used in small town homes or in trailers, it provides a steady supply of hot water for quite a long period of time. Most people also commented on how efficient this water heater was, especially considering it is electric.

What we didn’t like

One of the main complaints was that this water heater was not big or strong enough to provide hot water for a whole house.

When you read the product description, this is understandable – this machine is only 16 pounds and nowhere does it state that it is capable of providing hot water for a whole house. Some of the other commenters complained that the machine broke down frequently and that the customer service provided by Stiebel was less than adequate. When you are dealing with a smaller company, this is understandable.

what we didn’t like

The one issue that many people had with the Rinnai R94Lsi came with the service network that was available in their area. It seems as though it can be quite hard to find someone who will work on the Rinnai R94Lsi in even the most populated areas, so if you live in a small town, there is a good chance you won’t be able to find someone to service it.

How do Tankless Water Heaters work?

  1. When you open a hot water tap, cold water enters the heater and triggers the heating elements or burners. Your hot water tap acts as an ignition key for the energy used to heat the hot water you need. The start-up process only requires a couple of seconds.

2. The water is heated as it flows through the heating elements or heat exchanger. As the water flow varies, the unit adjusts the heating elements or burner flame to maintain a constant temperature and maximum energy efficiency.

3. When the hot water tap is turned off, the heating system also turns off. (excluding the pilot if so equipped)


How does a tankless water heater heat water instantly?

Tankless water heaters work much different than conventual storage type water heaters.
For example, when you turn your tap on this tell the heater to turn on. The gas burner will come on and instantaneously heat the water you need. The time it takes to get hot water is related to the distance the hot water has to travel from the water heater to where hot water is needed.

What would be the advantages of using a tankless system?

Since a tankless water heater comes on when you open a (hot water) tap and turns off when you close the faucet, the energy that is used is only for the hot water that is needed. Because there is no storage tank of water, and no constant heating and re-heating of stored water, you�re not losing energy heating water when you don�t need it, These energy savings translates to dollar savings for you and reduced impact on our environment. Since a tankless water heater heats the water as you use it, you can have an endless supply of hot water, Of course, this will depend on properly sizing the water heater.

Is it true tankless can provide an endless supply of hot water?

Because storage tank heaters store larger amounts of water, when that water in the tank is used up your shower goes cold and you have to wait for the heater to heat the water back up recovery time. Since a tankless water heater heats up the water as it passes through the heater, you will never run out of hot water, That is if you size your flow rate properly.

Will I still get the same temperatures for my shower that I am used to?

If you buy the right( tankless heater) for you needs you will never run out of hot water. Tankless water heaters function at a variety of temperatures that you can choose, and they can produce hot water at the same flow rate as your standard shower provides now.

Will one tankless heater service my whole house?

If I had to fill a hot tub, would a tankless water heater work?

Since tankless water heaters provide an endless supply of water, you can fill a tub of any size. It is only a question of time, meaning that our larger units can fill a tub faster than smaller units. Please keep in mind that some tubs require water at higher flow rates, so it may be necessary to limit the flow so that the tankless water heater can adequately heat the water that is being called for.
