A pool heater extends the swimming season, and it has to be plumbed into the filtration loop correctly. The heater, the pump, and the filter must work as one system.
The placement
The heater goes on the return side of the loop, after the filter, so the water reaching it is already clean and under pressure.
The flow
The heater needs enough flow through it, so the pump must match the heater's rating. Too little flow trips the heater's safety or damages the exchanger.
The bypass
A bypass valve lets some water route around the heater when you want to filter without heating, which saves wear and energy.
The gas or electric
Gas heaters need a gas line and vent, while heat pumps and electric heaters need the right electrical service. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Redwood City, the utility and the climate shape the choice.
The winter
The heater and the lines are drained or winterized before a freeze, or the exchanger cracks.
