We get a significant number of people looking for Navien Tankless water heaters on this site…. Yes they do have the highest efficiency rating of any tankless BUT… They (in our opinion) are the worst built tankless water heater.  If you feel we are wrong check out the comments we get regarding Navien errors and problems HERE or HERE.  As you can see there are numerous issues.

Price out a Rinnai Tankless, the rc98hpi is a condensing tankless with a energy factor of 94%.  It is a very stable unit with little to no issues. If your looking for stability and reliability they you will probably want to stick with Rinnai or another brand of tankless water heaters. But if you want the highest efficient tankless on the market you will want to go with a Navien unit.

Either way we offer access to all units and can get you an installed price quote for which ever way you end want to persue.

Tankless Brands

Posted by administrator in Installation Techniques

There are a number of different brands of tankless water heaters below you will find a short synopsis of each of each tankless system.

Rinnai Tankless

Easily one of the biggest suppliers of tankless units, they are known for stability and reliability. Of all the experience we have had with tankless water heaters Rinnai’s Tankless is by far the most reliable unit on the market today.

Navien Tankless

This one is often spelled incorrectly as “Navian”.  It has been know as the the most efficient tankless with their units reaching 98% efficiency.  They have had reliability issues in the past but they are on to the 4th generation now and most of the issues have been cleared up.

Noritz Tankless

Not the most popular brand of tankless but it is a nice unit none the less.  Reliability is lacking a bit but it makes it up in its efficiency.

Bosch Tankless

Commonly sold in Home Depots, these tankless systems are good units but they are so frequently incorrectly sized and installed that they have developed a bad reputation due to this.

Takagi Tankless

If for some reason I couldn’t get a Rinnai tankless I would choose the Takagi tankless model for sure, high efficiency, reliability, and easy venting.  What more could you ask for?

John Wood Tankless

This brand can be difficult to find in Toronto or Ontario for that matter, its mainly sold in the US and is made by GSW.
