I have a 330K BTUH heater here in Florida and I think it is a huge
waste of money. It feels like I am just burning dollar bills to keep
the pool warm. We seldom ever turn it on.
I do have solars and they work pretty well if you keep the pool
covered but I hate the cover too.
Usually we are resigned that the pool is going to be too cold to use
for 3-4 months a year. I switch the solars over to the spa and it is
toasty all winter for free.
All right, here's my 2 cents. Been doing this for 15 years, not pool
heaters exclusively, but installation, maintenance and repair of propane
Look at Sta-Rite heaters. They aren't as large as other brands (BTU vs
BTU), are power vented, and can be vented out a side wall if installed
inside. The biggest issue is lack of care in the fall as critters will
find a way inside and wreak havoc with insulation and wiring. I suggest
to customers that they wrap the heater as tightly as possible and spread
some moth balls or other rodent repellant to minimize invasion.
As far as heating goes, about one and a half degrees per hour is
average. A solar cover will help maintain the temp and you will use less
energy maintaining the temperature than letting the temp drop and trying
In my world there is no science that supports
that it takes less energy to heat a pool continously
as opposed to letting the temp drop and then
reheating. It's just like setting back the temp in
a house. Unless you have different energy
sources at different times or different energy
rates, you're always going to save money by
letting the temp drop, then reheating.

But think of the solar cover as insulation. They really do help. In NY, I
could regulate the temperature within about a +/- 4 degree window using the
pump (night or day) and the solar cover. I liked the water about 78-80F
unless it was above 90F and then maybe up to 82-84F.
to reheat. <<<<<<
This statement is incorrect.
If it were true why would setback thermostats be made?
If I left the pool heater on for two weeks while I was gone on
vacation, I'd use less energy
than if I turned it off for two weeks and reheated upon return?
*I have a few customers with pool heaters and most of the time they don't
use them except for parties due to operating costs. I have heard that
painting the bottom of the pool black will help boost the temperature
slightly. One customer has an array of solar water heater panels (More like
mats) on the lawn next to the pool, but I don't know how well it works. As
with anything that is heated, including your house, you need to minimize the
heat loss to keep the expense down. You already have a cover to help with
this. All of the gas heaters that I have seen are outdoors near the pool
It's rare to see them used here in NJ too. A lot of
people have them, but very few use them due to the
cost. OP says there is no room on the roof for solar.
Another option would be to install them on an angled
wood frame. But that only works if you have good
south or west exposure, room, can hide it somewhat,
There is yet another option. It would not be my first
choice, but there is a company that sells a solar heater
that goes in the ATTIC. It's basicly a heat exchanger
with a powerful fan that the pool water gets pumped
through. With a 32F delta between the pool water
temp and the attic air it delivers 60K BTUs. So, if
the attic is 107F, and the pool is 75F, you're getting
60K BTU for free. Whether it can work depends
on how big the attic is, how hot the attic gets, where
the attic is versus the pool, size of the pool and
if it's covered.
Google solar attic pool heater if interested.

A friend just installed a "lap pool" with about half of the pool
only about 6 inches deep, with black granite tile on the bottom. The
pump moves the water over the black shallow into the main pool -
heating the pool quite effectively.
