Is 250,000 BTU enough for my pool?

It suits pools up to roughly 10,000 gallons in a moderate climate. Larger pools or cold-climate use need a 400K model.

Does it run on propane or natural gas?

This version is set up for propane. A quick-change orifice lets a technician convert it to natural gas.

Can I install it myself?

No. Gas line, venting and electrical hookup require a licensed installer, and Pentair's warranty depends on professional installation.

How does it compare with the 400K MasterTemp?

The 400K heats bigger pools faster and costs more to buy and run. The 250K is the better fit for small pools and spas.

What maintenance does it need?

Keep water chemistry in range, clean or replace the filter regularly and have the heat exchanger and burner checked yearly.
