Sentry Pool Heater – Natural Gas

On demand pool heaters with thermal efficiency of 98 Percent

The Sentry Pool Heater is a commercial condensing water heater that is 98% efficient combined with a closed food grade glycerin loop and NSF 50 listed patented high efficiency heat exchanger directly submerged into the surge tank. The pool heater does not take in the pool or domestic water when heating instead we circulate and heat food grade non-toxic glycerin putting the BTU’s exactly where they are needed without exposing our system to any pool water. By doing this we are able to reduce energy consumption, lower operational costs and increase the operating life of the unit dramatically versus conventional pool heating systems and offer an industry leading warranty.

  • Does not ingest any pool water into the heater
  • Common venting
  • 98% energy efficiency
  • 10 year limited commercial warranty
  • Dual high grade stainless steel heat exchanger
  • Minimum 18,000 to max 199,000 BTUh per heater
  • Indoor and outdoor compatible
  • Space saving wall mount or floor mount designs
  • Modular units with maximum firing rate of 199,900 btuh each
  • Approved for common venting for up to six units allowing for 1.2 million btuh
  • Submerged heat exchanger for installation within surge pits
  • Optional flat plate titanium heat exchangers for installation without surge pits
  • Sealed combustion with dedicated combustion air intake and exhaust
  • Power requirements two 20 AMP GFCI circuits, 110 volts, single phase power
  • Heating system is not interrupted by backwashing or bump maintenance cycles
  • BACNET adaptable for use with building automation systems
  • Compact design reduces the footprint needed for both new construction and renovations
