  1. Raypak R406A-MN Natural Gas Pool Heater 399K BTU (Millivolt)      
Raypak 399k BTU Millivolt Nat. Gas Pool Heater

The Raypak Millivolt gas heater is built with one mechanical thermostat. This control allows you to set your pool or spa temperature precisely at your favourite setting and the heater ensures the temperature stays that way, alleviating you of constantly checking to make sure it’s correct. 

Raypak’s Unitherm Governor is a standard feature across all digital models which helps reduce condensation from low inlet water temperatures. The Unitherm Governor automatically regulates the water flow to help keep the water temperature appropriate for swimming. The need to control water temperature and water flow rate is important because both measurements set correctly, eliminate condensation, sooting, and scale buildup that can shorten a heater’s life. If we had to point out one downside is that the mechanical thermostat isn’t truly innovative.
