This heater has many great features that make it stand out from other models on the market today:

  • It’s easy to install, you can have it up and running within an hour! Plus, there are no tools required for installation (just use your hands).
  • The Hayward Universal H-Series 200k BTU unit comes with two cast iron burners with brass fittings that provide high efficiency operation while minimizing maintenance costs over time.
  • This model operates at 83% efficiency so it won’t cost you more money than necessary when heating up your pool or spa water; also note how small these units are compared against similar ones sold elsewhere online–this means less space needed inside your home/garage before installing them too!


The Hayward H200 Pool Heater is packaged in a box that measures roughly 5 feet by 2 feet by 2 feet. The heater weighs about 108 pounds, so it’s not something you want to be moving around on your own.

The packaging is solid and sturdy, with thick Styrofoam protecting all sides of the unit as well as cardboard dividers separating each individual part from another. Once you open up the top flap on top of the box, you’ll see a user manual included with instructions on how to install your new pool heater (or spas). It’s very easy to follow along with these instructions if this is your first time installing one!

Hayward 200 000 BTU pool heater’s Surface area

600 sq ft is the surface coverage area of this heater. The surface area is a measure of how much heat can be generated by an H-Series heater, and it’s one of the most important factors to consider when purchasing one.

The larger the pool, the more powerful your heater needs to be. If you have a small pool but want to keep it warm during winter months or chilly nights, then consider getting a smaller model with less wattage (like our 100kW model).
