How to choose an electric sauna heater
An electric sauna heater is the simplest way to run a home or commercial sauna: it plugs into your electrical supply, heats a bed of sauna stones, and holds a steady temperature at the touch of a button — no wood, no venting, no daily clean-out. The single most important choice is power (kW), and it comes down to the volume of your sauna room. As a rule of thumb, allow roughly 1 kW of heater output for every 1.3 m³ of room volume (length × width × height), then add capacity for glass doors, uninsulated walls, or exposed stone. Get the sizing right and the room reaches temperature quickly and holds a soft, even heat; undersize it and the heater runs flat-out and still struggles.
| Sauna room volume | Recommended heater | Typical use |
|---|---|---|
| 2–5 m³ | 3.5 kW | Compact 1–2 person home sauna |
| 4–6 m³ | 4.5 kW | Small home sauna |
| 5–8 m³ | 6 kW | Standard 2–3 person sauna |
| 7–10 m³ | 8 kW | Family home sauna |
| 9–13 m³ | 9 kW | Large home sauna |
| 10–15 m³ | 10.5 kW | Large / premium home sauna |
| 13–20 m³ | 15 kW | Commercial / studio sauna |
| 18–28 m³ | 18–20 kW | Large commercial sauna |

Harvia vs HUUM: which electric sauna heater is right for you?
Calore stocks two of the world's leading sauna-heater brands. Harvia is the Finnish benchmark — the widest range on the market, from budget-friendly wall heaters to heavy commercial units, with a model for almost every room and price point. HUUM is the design-led Estonian maker, known for sculptural heaters, generous stone capacity, and the polished UKU WiFi app. Both build genuine, sauna-grade electric heaters; the right choice depends on your budget, your sauna's size, and how much the look of the heater matters.
| Harvia | HUUM | |
|---|---|---|
| Origin | Finland | Estonia |
| Signature models | Vega, KIP, The Wall, Cilindro, Virta, Spirit, Club, Legend | DROP, STEEL, HIVE |

| Starting price (CAD) | From $768 | From ~$3,300 (with controller) |
Choose Harvia if you want the broadest selection, the best entry price, or a heater for a large or commercial sauna. Choose HUUM if design is a priority and you want a statement heater with app-based WiFi control. Both are backed by manufacturer warranties and shipped across Canada by Calore.
Matching power to room size: 6 kW, 8 kW & 9 kW heaters
Most Canadian home saunas land on a 6 kW, 8 kW or 9 kW electric sauna heater. A 6 kW heater suits a standard two-to-three-person room of roughly 5–8 m³. An 8 kW heater is the sweet spot for a family-sized sauna of about 7–10 m³. A 9 kW heater handles a larger room up to about 13 m³. Above that, step up to 10.5 kW or the commercial-grade 15–20 kW units. Remember that heaters between 8 kW and roughly 11 kW usually need a 240V three-phase or a dedicated single-phase circuit — always confirm the electrical requirement on the product page and have a licensed electrician complete the hook-up.
Wall-mounted, floor-standing & WiFi-controlled options
Wall-mounted electric sauna heaters — like the Harvia Vega, The Wall, Spirit and KIP, or the HUUM DROP — bolt to the wall to save floor space, and are the popular pick for home saunas. Floor-standing (pillar) heaters such as the Harvia Cilindro, Club and Legend Pro carry a much larger stone mass for a softer, more generous löyly (steam), and are built for bigger and commercial rooms. Many models add WiFi and app control, so you can pre-heat the sauna from your phone and step into a ready room. Filter by mounting style and power at the top of this page to narrow the list to the heaters that fit your space.

Electric sauna heater FAQ
Are electric sauna heaters any good?
Yes — electric sauna heaters are the most popular choice for home and commercial saunas because they are convenient, low-maintenance, safe and consistent. They heat a bed of sauna stones to deliver the same authentic radiant heat and steam as a traditional stove, but with push-button or app control and no wood, smoke, or venting to manage.
What type of heater is best for a sauna?
For most indoor home saunas, an electric heater is best: it's easy to install, easy to run, and gives precise temperature control. Wood-burning stoves suit off-grid or cabin saunas where ambience matters and power isn't available, while infrared is a different, lower-heat experience. For a true Finnish sauna with steam (löyly), a stone-topped electric heater from Harvia or HUUM is the standard choice.
What size (kW) electric sauna heater do I need?
Allow roughly 1 kW of heater output for every 1.3 m³ of sauna room volume. A 6 kW heater suits about 5–8 m³, an 8 kW heater about 7–10 m³, and a 9 kW heater up to about 13 m³. Add capacity for glass doors or uninsulated walls. Use the sizing table above, or send Calore your room dimensions for a precise recommendation.
Do electric sauna heaters use a lot of electricity?
Less than most people expect. A heater draws its full rated power (say 6–9 kW) only while heating up; once the room is hot, the thermostat cycles it on and off, so average draw is much lower. A typical 45-minute home-sauna session on a 6–8 kW heater uses roughly 3–5 kWh. Good insulation and pre-heating with a timer or WiFi app keep running costs down.
Can you pour water on an electric sauna heater?
Yes — on a traditional stone-topped (löyly) electric sauna heater like the Harvia and HUUM models sold here, you ladle water over the hot stones to create steam. Use clean water in small amounts and never pour water directly into the heater body or onto the electric elements. (Water should not be used on infrared heaters, which have no stones.)
What is the "200 rule" for saunas?
The rule of 200 is an informal comfort guideline: aim for the air temperature in °F plus the relative humidity in % to add up to about 200 for a pleasant löyly. For example, 170°F with around 30% humidity, or 150°F with around 50% humidity. It's a quick way to balance heat and steam — hotter air calls for less humidity, and vice-versa.
Harvia vs HUUM — which electric sauna heater is better?
Neither is universally "better" — they suit different buyers. Harvia offers the widest range and the best entry pricing, plus heavy-duty options for large and commercial saunas. HUUM focuses on minimalist, design-led heaters with large stone capacity and a polished WiFi app. Choose Harvia for selection, value and commercial power; choose HUUM for design and app control. See the comparison table above.
Do electric sauna heaters need special wiring (or is there a 110V option)?
Most sauna heaters above about 4 kW require a dedicated 240V circuit, and larger 8 kW+ units often need three-phase power — always check the electrical spec on each product page and use a licensed electrician. Small plug-in 120V (110V) heaters exist for very compact saunas but are limited in output; for a genuine Finnish sauna experience, a hard-wired 240V heater is recommended.
Which electric sauna heaters do you ship across Canada?
Calore ships every Harvia and HUUM electric sauna heater in this collection across Canada, along with matching controllers and sauna stones. If you need help choosing between models or want a delivery estimate for your area, contact our team.
Is it safe to use an electric sauna every day?
For most healthy adults, daily sauna use is considered safe and is associated with relaxation and recovery benefits. Stay hydrated, limit sessions to a comfortable length, cool down between rounds, and consult your doctor if you are pregnant or have a heart condition or other medical concern.
