Members expect hot showers straight after a class, every time. We size systems around your gym's real peak-hour usage.

Gyms have sharply peaked hot water demand — early morning, evening, and immediately after group classes, when a large number of members shower within a short window. Members notice cold water at exactly these moments, so we size systems around your club's actual peak usage rather than an average across the day.
Clubs with a pool or sauna add further, separate demand — for pool-specific heating, see our swimming pool heat pump page. For the underlying commercial system approach, see commercial & industrial heat pumps.
Peak demand: Morning, evening and after group class hours
Facilities served: Showers, saunas, optional pools
Benefit: Consistent hot water even at simultaneous peak use
Sizing: Based on member capacity and peak-hour usage

Yes, when sized with your busiest class times and member capacity in mind, including adequate hot water storage buffer for that short peak window.
Yes — pools use a dedicated pool heat pump (see our swimming pool heat pump page), while saunas are assessed individually based on the heating method used.
We look at member capacity, class schedule and peak shower windows during the free site survey to size the system for your busiest realistic hour, not just daily average use.
Gyms with heavy, continuous shower use typically see a strong running-cost improvement versus electric immersion heating, given the volume of hot water used daily.
