Pool Heaters
How to choose pool heaters
Heater vs part
Decide between a full heater (Pool & Spa) and a spare part (Pool & Spa Accessories) by checking if your current unit powers on.
Heat source
Choose electric for convenience or wood for off-grid use, knowing electric needs wiring and wood needs venting.
Build material
Material sets the tradeoff: wood for looks, steel for simplicity, stainless steel for corrosion resistance, aluminium for light weight.
Finish
Colour (black, grey, white) is a minor choice but matters if the heater sits in view of a seating area.
Sub-type scope
Note the Home & Garden sub-type may include broader items, so confirm the listing is a heater or a related accessory.
What's good
- A replacement heating element (Pool & Spa Accessories) fixes a dead sauna or pool heater without replacing the entire unit.
- Electric heaters with steel or stainless steel bodies give steady heat for a home sauna or spa, with no need for fuel storage.
- Wood burning heaters (Pool & Spa, material wood) heat off-grid, suiting garden buildings away from mains supply.
- Flow switches and flanges (Pool & Spa Accessories) let you build or repair a heat pump pool system with standard G3/4 fittings.
- Black, grey, or white finishes let the heater match surrounding tiles or garden wood.
Things to watch
- Wood burning heaters need a flue and regular ash removal, so they are wrong for a sealed indoor pool room.
- Electric models at higher kW ratings need a dedicated circuit, not a standard socket, which adds install work.
- Replacement parts like elements or embedding flanges only fit existing units, so they are useless for a first purchase.
- Steel bodies are tough but can corrode near chlorine, while stainless steel resists it yet weighs more.
- Accessories such as paddle flow switches have moving parts that can clog in dirty water, needing checks.
Care & maintenance
Surface care
Wipe steel, aluminium, or stainless steel surfaces after each use to remove chemical residue.
Flow switch check
Inspect rotary paddle flow switches each season for trapped debris in the paddle or thread.
Wood burner upkeep
Clear ash from wood burning heaters and check the black or grey shell for cracks.
Scale control
Descale heating tubes if your water is hard, to keep heat transfer efficient.
