Find the perfect 7.5kW sauna heater for your medium-to-large sauna right here. This specific power level is the ideal solution for rooms that are slightly too large for a 6kW heater but don't quite require the full power of an 8kW unit. Our selection provides robust and efficient heat for a perfectly balanced sauna experience. Need a different size? Explore our full range of sauna heaters.
A 7.5kW heater is an excellent choice for saunas in the 250 to 390 cubic foot range. To get a precise recommendation based on your room's specific dimensions and features, we strongly recommend using our official sauna heater size calculator to ensure the perfect fit.
Similar to an 8kW heater, a 7.5kW unit is a powerful appliance that requires a dedicated 240-volt circuit, which must be connected to a 40-amp breaker. This is a hardwired installation that must be completed by a qualified and licensed electrician to ensure safety and proper functionality.
Choosing a 7.5kW heater is all about precision. If your sauna's cubic footage is on the upper limit for a 6kW heater (or has extra glass/windows), stepping up to 7.5kW ensures you'll never feel underpowered. It provides that extra boost for a faster heat-up time and better performance.
While not as common as other sizes, trusted brands like Harvia are well-known for producing heaters in these precise ".5" increments. They offer these models to ensure you can find the exact right heater for your specific room dimensions, which you can explore in our product selection below.
