How do I drain the water from my Hayward heater for the winter

Did you drain it completely before Winter? If water was inside the pump, it could have been damaged by expanding freezing ice. The impeller could be trashed (i.e. ''physically broken'').

either blow water out with a blower then follow with a little antifreeze to make sure all water is out then remove freeze plugs on sides of heat exchange then remove pressure switch turn off gas valve and put a board or something on the top to keep out snow and weather

Which type and brand water heater?
Tankless?

Boiler, solar, indirect, hybrid, combo, heat pump, etc?
Most have a drain valve.

Make sure that you drain all of the water out of the pool heater to prevent damage during freezing weather. That is the most important thing you can do to winterize pool heaters. If you have a cover, you might want to use it to prevent weather related exposure, but as long as you have the water out, you will be ok.

That is the drain plug...underside of the inlet/outlet header. You should also break open the connection of the water tube to the pressure switch inside the heater to prevent the switch or tube from freeze damage.

Drain it using the drain valve on the bottom-side of the inlet/outlet header; make sure the heater sits level or slightly tilted down on the header side. You also need to drain the water tube that feeds the pressure switch inside the heater cabinet. Turn off the gas and power off the circuit and you are done. If you cover it DO SO LOOSLY! Wrapping it tightly and not allowing air to flow thru will lead to rapid rusting of all the sheet metal.

Other than the drain you'll need to remove the pressure switch from its feeder tube and leave it hanging by its wires for the winter. Be sure the heater is level or tilted towards the header to allow all the water to drain out. More than a few people have lost a heat exchanger to freeze damage after draining it because the heater wasn't level and water remained in the low end of the tubes.

pull the three (or so) drain plugs in your heater ... use a shop vac (without the filter in it) to blow and then **** out any remaining water.

hopefully, your pressure and suction pipes lead away and down from the boiler. Make sure you **** out those pipes as well.

You know how to drain your filter(s) and pumps ... right?

I hope this helps you

Are you asking how to drain it? If so some older models come with a drain **** located on the bottom side of the black manifold. It is brass. You can loosen the drain **** and the water will drain out, be careful when tightening the drain **** back up though, they can break easily. You do not have to put much torque on it at all, dont even put a tool on it at first, if it leaks, then tighten it a little more. The newer models come with a brass plug instead of a drain **** and you can remove the brass plug. Or the best way i think is to unhook both unions for the inlet and outlet on the heater, use a shop vac on blow, and blow the water out. But if you are winterizing the pool equipment, the heater is not the only thing that needs to be drained.

On the side of the heater, you will see the water connections. Directly underneath them, on that black component that they attach to, there is a drain plug of some description. It may be a draincock, or just a plug. In either case, simply open or remove it to safely drain your heater. In a pinch, you could also disconnect the water connections at those unions (the big grey connectors), but they can be fussy to reassemble, and you run the risk of losing the o-rings.
