I've got a pool / spa. We don't use the heater much but it's important when we need it. My 10-12 year old laars lx is unreliable.
I'm thinking raypak since they are simple and without a lot of the drama. Life expectancy and reliability are more important than efficiency. Gas is cheap in ga, elec expensive so a heat pump is out of the equation
We probably use the heater 10-15 days a year. I've considered building a schedule so it fires for an hour or so once a month to keep the sensors from getting funky. In the last 6 months I've lost two sensors and an igniter. I fix it myself , but the parts are overpriced.
Raypak makes a number of models all within $500 or so of each other. On a sw pool, is the premium warranted?
