Pentair 460734 Master Temp 300k BTU Natural Gas Pool Heater

When spring is in the air, pool owners across Canada get ready to welcome summer, and get the pool ready for swimming. But sometimes, it can take time for pool water to catch up with the beautiful weather outside. On the first true days of summer, it can be disappointing to face a pool that is too cold to enjoy.

Adding a heater to your pool is one of the best ways to ensure that it is open and ready for action every single day of the summer season. With the Pentair Master Temp heater, you have the option of opening your pool earlier, closing it later, and enjoying the perfect water temperature - even when the weather hasn't cooperated.

I and my wife were looking for Pentair 300k BTU for a month or so and none of the supplies had it. We almost gave up and wanted to switch to the other brand but all the sudden Toronto Pool Supplies was the only one who had it, so I placed an order right away. So happy. Great customer service too!
Easy order online and easy-going pick up process. Happy to switch to Pentair because of 2-year warranty! THANKS
10/10 best pool company in Canada so far!
My previous heater was bought 10 years ago and I had no choice rather than buying a new one. Folks Pentair is the brand you definitely looking for. You must be lucky if you will find them somewhere else - they all are being sold quickly!
