Key Takeaways

  • A heat pump turns a seasonal pool into a year-round one, which is where most of the value comes from
  • Running cost is low, around $1 per hour on the 35kW unit, because it moves heat rather than making it
  • CHR units are backed by a 5-year parts, 15-year compressor and 25-year heat exchanger warranty, plus a 48-hour on-site service guarantee

A pool heat pump is a considered purchase, so it is worth asking whether it earns its place. For most homeowners the answer comes down to one thing: how much more you use the pool once the water is always warm.

The real value is year-round use

A pool that is only comfortable for a few weeks each summer sits unused for most of the year. A heat pump changes that. It keeps your pool and spa warm across the year, so the investment you have already made in the pool actually gets used. That is where most of the value is, in the swims you would otherwise miss.

Low to run

The ongoing cost is modest. A heat pump moves heat rather than making it, returning up to 20 units of heat for every 1 unit of electricity, and the CHR 35kW unit costs around $1 per hour to run. That is far less than gas. 

Built to last

A heat pump is a long-term purchase, so how it is backed matters. Every CHR AstroMax unit comes with a 5-year parts warranty, a 15-year compressor warranty and a 25-year heat exchanger warranty, along with a 48-hour on-site service guarantee and local support. It runs on standard single-phase power, so most homes need no electrical upgrade to install one.

Is it worth it for you

If you want to swim across the year rather than a few weeks in summer, and you want warm water on demand at a low running cost, a heat pump is a considered investment that pays you back in use. To match one to your pool, see what size heat pump you need, or get in touch with our team.
