Heat Pumps in north Texas ?

[Seanhan13]

Is anyone using a heat pump in North Texas with any luck ?
All the burners rusted out on my Raypak 406A in just 5 years, I was told today that using the heater in the winter created condensation that is acidic and caused the burners to rust. But don’t you want to use the heater in the winter ???
anyway Is a heat-pump even a option in north Texas ?
I have a 30k gallon pool and 500 gallon spa.
my current gas heater is natural gas.
the Raypak heater I had before this one was the same model and lasted for 20 years. Guess they don’t make em like they used too.

Damage that fast is usually caused by a leaking heat exchanger. The refractory material (fire brick) is severely damaged. When there is an internal leak the material get soaked. When the heater fires the water almost instantly turns to steam and literally blows the material apart. Could also happen if the heater is subject to a lot of rain, as in falling from a roof with no or bad gutters.

Do you mostly heat the pool in the winter, or the spa? Heat on demand, or run the heater all the time?

Acidic condensation shouldn't be an issue if you are heating your spa on demand or if you keep your pool continuously heated to a high temperature. But heating a pool on demand from 50-60 degrees would produce corrosive condensation that could damage your heater.

If you like to quickly heat your spa on demand (as I do with my gas heater), you probably wouldn't find a heat pump's performance to be satisfactory, especially at colder temps.
