Keep the heat before buying more capacity
Evaporation is a major source of pool heat loss. A suitable cover can change the operating cost and equipment size, especially on exposed coastal plots.
A pool heat pump works most efficiently in milder air temperatures. Running it during solar hours can improve self-consumption, provided filtration and other house loads are coordinated.
Pools are a useful flexible load
Unlike refrigeration or security systems, heating and filtration can often be scheduled. A selected installer or supplier may consider Kosner pool heat pumps where the pool, exposure and operating season suit them, making better use of midday solar surplus without automatically adding a large battery. Availability is not guaranteed.
