L on Mar 8, 2019
Do you have a propane kit for the 175000 unit 460792? and $

What does HD model mean?
A shopper on Dec 5, 2016
BEST ANSWER: heavy duty...inside the coils are made of nickel instead of copper which corrodes fast. There are some other differences, too, but that is the main thing.
Is this a good replacement for Pentair 250DV?
David B on Feb 22, 2021
BEST ANSWER: I have replaced 3 Pentair 250 DV's with the 250 Master Temp heaters. I think the Master Temp units were a good choice for us. The additional cost for the HD cupro nickel version is worth the the expense. The plumbing connections and exhaust are completely different.

A shopper on Dec 22, 2017
BEST ANSWER: Ours measures as best I could is 1 1/4" over to the equipment and then 1" to the heater.

Exactly as described, easy install.
Decided it was time to get a pool heater but didn't have any knowledge of the subject. Called the pool supply tech line to get a little guidance. Was told to get the cupro nickel model since I have a salt water system. Now the pool is the PERFECT temperature all the time! Excellent customer service.
