Hayward H250 Pool Heater

The Hayward H250 is part of the Hayward H-Series Millivolt pool heaters range which may not represent the very latest in heating technology for swimming pools and spas but are still a good choice if you require a millivolt heater (if there is no electricity supply).

H-Series Millivolt heaters are gas heaters (models for natural gas and propane) and are easy to install and maintain, thanks to their low profile, light weight and CPVC plumbing capabilities. Hayward have been reducing the number of medels available in this range and presently only list one but you can still buy the full range from 150 – 400k BTU/hr. Of course these are not low NOx so will not be allowed in some locations.

The Hayward H-Series Millivolt heaters include a wealth of features to deliver precise water temperature control and achieve the ideal swimming pool and spa comfort level. They are also built to last.

Features include:Hayward H250 Pool Heater

  • Single header “V” baffle design heat exchangers which facilitate long life, fast heating and virtually no condensation.
  • Heat exchangers constructed with highly resilient Cupro Nickel for greater durability and longevity.
  • Rust resistant water path with injection-molded polymer header. This provides improved by-pass control and extends life by providing additional protection from the damaging effects of corrosion from high flow conditions and from occasional pool chemical imbalances, making the unit ideal for salt-chlorinated pools.
  • Burner system constructed of stainless steel and can easily be removed for cleaning and maintenance.

Together, these added technological improvements ensure that your Hayward heater outperforms and outlasts expectations. However, it has to be said that Millivolt heaters are old technology and are not allowed in some states. You would only buy one if it would be prohibitably expensive to install an electricity supply.

These heaters are not widely available. However we did find a good range at Aqua Swimming Pool Supplies (February 2018). To see their prices click the link below:
