Pentair MasterTemp 400K BTU Natural Gas Heater HD

I have to say, I am so glad I bought from this site. Ordered at around noon on Sunday, I was expect it to arrive in 2-5 days, 9:15am the next morning, the driver called me to ask me where I wanted him to put the heater. The best delivery I've ever had. The heater is great. After installation, I had problem of it shutting off and service light coming on. After trouble shooting, I found out that I didn't have enough water pressure coming into the unit. The 400K BTU does require a minimum of 44gpm intake. I ended up replacing the decades old pump and filter for a pair of Pentair units (also bought from this site, also got outstanding delivery). Everything's been working flawlessly ever since.

Ordered this to replace a 13 year old Jandy. It is about 1/2 the size and weight. I ordered the HD due to having a salt pool and everything looks well built and sealed up to prevent any future rusting. Only time will tell now.
