How and when you use your pool will determine which of the three categories of pool heating technologies are going to fulfill your requirements.
For performance (speed of heating), efficiency (energy consumption vs energy output) and cost (purchase cost and operating cost).
We can help you determine what’s best for your situation.
It is important to either install or have provision for heating at time of new pool construction as it is far easier and more cost effective than attempting to do this later.
For solar you need roughly 70-100% square meter area of the pool, available on the roof for the panels.
The area needs to be on NW, N, or NE exposure side of your roof. Initial install costs is roughly the same as a heat pump but of course the heat is free thereafter. As sunlight is not always dependable, speed of heating may be slow or non-existent.
A Heat Pump is like a fridge working in reverse, using free heat extracted from the ambient air and then efficiently transferring it to the water. Because they ‘extract’ heat from the air it only takes one fifth of the energy to run them
as they produce. i.e.
A heat pump may produce 6 to 10kW of Heat energy for every 2kW it consumes. We use and recommend Hot Water Heat Pumps Limited: waterheating.co.nz
Remember also that a pool cover is the most energy efficient product for your pool. Pool covers insulate and trap sunlight heat as well as preventing evaporation.
