The
28-C Series is the tankless solution for the high-end Paloma House that
luxuriates its owners in an abundance of hot water. There is a 28-C
solution for the water needs of any and every home.
Very simply, the 28-C is a hot water server that can be installed as
a multi-unit system to give you twice, thrice, even four times the volume
of hot water of a single 28-R Paloma…on up to a colossal system
consisting of 20 Palomas acting in concert as a single system.
The brains for this system reside in a special multi-unit digital controller.
Do you need the abundance offered by the 28-C Series? Perhaps,
if…
| You
are afraid that a single 28-R Paloma will not keep up with the simultaneous
hot water demand during the daily shower-time rush…or |
|
You need a solution for the holidays, when who knows how many
showers will be called into action…or
|
| You
need a hot water solution that will keep up with the hot water wonderworld
you are building into your new home…or |
|
You
simply want to take advantage of the fast-fill capability of your
new whirlpool tub, at rates of 8 or 10 gallons per minute.

Paloma 28-C Home System Sizing Reference
Here is a quick look at the hot water
capacity of 28-C Systems that will meet the demand of nearly all home
applications.
The numbers in the colored columns give you the flow rate of hot water
at showering temperature at the coldest point in the year.
The colors tell you how many showers this system can handle at one time.
For larger systems, or for complex requirements, consult with a Paloma
Consumer Advisor.
