Andy talks about the remote control option on the Paloma branded tank, its important to know that these systems are able to support multiple remote control points at various locations in the home. This makes it convenient for adjusting water temperature right at the source, say a shower or bathtub. This is a feature that most manufactures are supplying with their tankless units.

Firstly let’s get this straight; Navien is a brand of tankless hot water heater not Navian. I have seen this 
spelled wrong many times, Navian (I googled it) is nothing, definitely not a tankless water heater.
Navien has 6 residential models (CR-180, CR-210, CR-240, CR-180A, CR-210A, CR-240A) and then 3 commercial units (CC-180, CC-210, CC-240). These tankless water heaters are all relatively similarly designed but as you go up in model number you increase the amount of hot water the tankless unit can provide. Here is a quick list of each units performance.
- CR-180 and 180A are able to provide roughly 3.8 gallons per minute with a 77 degree F rise.
- CR-210 and 210A are able to provide roughly 4.5 gallons per minute with a 77 degree F rise
- CR-240 and 240A are able to provide roughly 5 gallons per minute with a 77 degree F rise
We should definitely look at the efficiency of the Navien tankless water heater which is currently the only condensing unit on the market. This extra step gives Navien the efficiency title, currently rated at 98%, therefore 98 cents of every dollar spent on heating your water is actually turned into hot water. This is an amazing number as most tankless water heaters are 10% to 15% less efficient. Of course being the first on the block has its issues, the Navien tankless water heater is facing some problems from rubber hoses becoming blocked. This has been reported numerous time in several forums around the internet.
The good thing is that most of the other Tankless water heater manufactures are working on their own form of tankless condensing units. This should give the consumer a good choice in high efficiency water heating.

UPDATE
This write up was done in February of 2009 so its been over a year now and there are a number of alternate condensing tankless water heaters available now. Navien was the first on the block and realistically you cant beat the price of the unit, even today its still lower than all condensing tankless units. Sure there has been some issues regarding the system but thats to be expected from a new technology (we will be authoring a new post on all these problems and their fix, check back soon).

Paloma Tankless Systems
Dec 3rd
The Paloma tankless water heating system can be a good choice for large homes that are using more 
than one water source at the same time. These systems also have the added benefit of using either propane or natural gas, depending on which model you choose. However the Paloma Tankless system is a rather large unit that doesn’t come with a lot of bells and whistles as far as controls are concerned. Overall it is a good system, but there are other options that are slightly better. The Paloma’s warranty is still one of the best in the business at ten years on the heat exchanger and three years on all other parts.
These systems are manufactured outside of north america, so if you are looking to buy a little more local look at the Rinnai Tankless systems, which is built in the USA.
