WHAT SENTRY CLIENTS SAY“This system is operating above and beyond expectations.”
View Full TestimonialWe recently replaced our pool heater at Summit Middle School with 98% efficient Sentry Pool Heaters. This system is operating above and beyond expectations. The pool runs at a more constant temperature and with the installation of the more fuel-efficient pool heating equipment that is Energy Star rated we also received a rebate from our energy provider (MidAmerican Energy) in the amount of $8,151.00. The energy efficiency rebate alone paid for a good part of the pool heater project. The fuel efficiency of the new pool heating equipment will soon pay for the rest of the project. We are very happy with the completed project.

View Full TestimonialThe Sentry indirect fired pool heating systems combines modern technology and efficiency with a common-sense approach to heating swimming pool water. The aquatic industry no longer has to rely on temperamental single-unit pool heaters exposed to corrosive swimming pool water. Sentry’s submerged heat exchanger allows for a practical and more efficient solution to transfer heat to the pool water.

Sentry brand unit.”In one year of operating our New Sentry brand heaters have had zero unplanned failures and we are saving $18,000 per year(On average/per site) in natural gas. Our visitors are having a better experience in our facility due to consistent water temperatures and no unplanned pool closures. Any pool heater we replace moving forward will be a Sentry brand unit.

WHAT SENTRY CLIENTS SAY“Installing this system was the best use of

our money to improve conditions in our pool.”We installed our new Sentry heater at the Maytag Pool in the spring of 2022. We had previously used an old gas heating system that was very ineffective and extremely hard to keep consistent. We visited with several surrounding communities that had the Sentry system and we were provided with positive and encouraging reviews. Once we decided to go with Sentry, we could not have been happier. They built our system right in their shop and provided updates on the progress. They dealt with all the necessary permits and requirements and made the process as seamless as possible. Once our system was ready, they had it installed in just a couple of days. They gave my entire crew a training session and made sure all of our questions were answered. The system itself is extremely user friendly, and very low maintenance. That was a big draw for us. I turn the system on and it basically runs itself. My lifeguards rarely have warm water when they begin their training in the spring. This year we had no complaints! Installing this system was the best use of our money to improve conditions in our pool. I would highly recommend this system.

WHAT SENTRY CLIENTS SAY“I’m still amazed after two years how much easier my life has been without having to deal with the constant stress from the old pool heating system.”
View Full TestimonialI would like to thank you again for providing The Sentry Pool Heater system that you installed at our facility in 2017. It is very reassuring that everything is still in excellent condition. I am still amazed after two years with this swimming pool heating system and how much easier my life has been without having to deal with the constant stress that the old pool heating system had challenged me with. No more working on boilers in the middle of the night and in the dead of winter when it got cold enough to freeze up the air pressure switches. Believe it or not I actually spent one Christmas Day working on those darn boilers! The Sentry Pool Heater is almost 100% maintenance free and with 98% thermal efficiencies almost just as efficient! The Sentry Pool Heater honestly has been a life changer not just for me but our whole organization since the swimming programs are no longer impacted by malfunctioning boilers. The Sentry Pool Heater is very much appreciated at Blue Valley Aquatic Center.

WHAT SENTRY CLIENTS SAY“we are already seeing the savings in utilities, chemical usage, and especially in maintenance staff time.”
View Full TestimonialOur new Sentry Pool Heaters are by far the most efficient and economically engineered pool heating system I have known in my 20+ years of working within the field. Mark Pleva and the Sentry Heating system solved a two-decade recurring problem at our community center, and we are already seeing the savings in utilities, chemical usage, and especially in maintenance staff time. We plan on upgrading our hot tub heating system using the same Sentry Pool Heater and their Smart Controller within the next budget year. It’s been a gamechanger for us and I highly recommend Mark Pleva and these heaters to anyone looking for new pool heater system.
