This Heat Pump Lab test
page is dedicated to everybody who once believed in the pool
heating urban myth that heat pumps don't work in dry, low
humidity conditions like the Nevada desert.
Our
goal is to demonstrate what a swimming pool heat pump can do
24/7 365 days a week on a pool in dry desert weather conditions.
Below you can view 2 pictures of our cameras broadcasting the pool and
the heat pump control panel. We have also attached a thermostat in the
water inlet and the water outlet of the heat pump to demonstrate the
changes in the water temperature. There is another thermostat
broadcasting the air temperature at the same time.
For
our test we used an inflatable aboveground swimming pool that holds
around 8,000 gallons. We selected this type of swimming pool because
aboveground swimming pools loose heat faster and we love a challenge.
For this size pool, 18 ft round, we need at least 50,000 btu's for a
desert weather application.
We
want to give an special thanks to Ruud for volunteering a Ruud 6350Ti-E-HC for this test,
Mr. Terry Doyle at Ruud for his technical help and Mr. Peter Zaharuk for being
our go-to guy for everything else. And to our dear Jason for assembling
the pool, installing the live webcams, supervising the installation,
attaching the thermostats and taking on this huge task of supervising
this test continuously. Jason we love you and it's ok to cover the pool
camera if you decide to test the water yourself in your Speedo.

This video is in my backyard in Las Vegas Nevada on
December 17th, 2008 during a VERY rare snowstorm which ended up
covering the entire city with 2 + inches of snow, some parts of town
got 8+ inches and it lasted on the ground for over a week. In this
video, my old Heat Siphon was running in the afternoon when it started to
snow and I went out to take a video, showing it running in 32 degree
air with 90% humidity and actually heating my pool. The water in the
video was only 65 degrees because I had the heater off for the previous
several days, otherwise it would maintain my pool in the low 80s every
day without a problem. This heater does not have power defrost, it is a
standard heat pump and later on that day it did shut itself down
because of too much snow/ice build up. After the snow melted overnight,
the heater came back on the next morning with an air temp around 36 and
continued to heat my pool just fine.
