The electrical arithmetic, ours
Divide 6 kW by 240 volts and the load is about 25 amps. Sized at 125 percent as a continuous load, that asks for more than 31.3 amps of circuit capacity. The arithmetic is ours and offered as briefing material only. The decision belongs to a licensed electrician working from your panel and local code, and this site publishes no wiring instructions.
No published price
Sun Valley page shows one price ($2,347) across 6/9/11 kW variants without per-kW breakout, so no price is attributed to this variant.

Who it suits, and who should skip it
Suits
- • The three to five person rooms most people actually build, where this power class lands mid-window instead of at an edge.
- • People whose ideal session starts with a switch and ends without ash.
- • Buyers who will actually use app preheat, which means walking out to a room already at temperature.
Should skip it
- • Nobody obviously on the stated specs. The calculator will say if your room disagrees.
How it sits in the field
Set against the rest of the database, the numbers place it. At 6 kW it sits below the 8 kW median of the heaters we track. Its published range spans 4.0 cubic meters, a wider window than the median, which gives a room more margin to land mid-range. The stated stone load of 75 kg sits at or above the 55 kg median of the models that publish one. Comparisons here use only records that publish the figure being compared, and each one is recomputed whenever the database changes.
What the publisher states, and what it does not
Of the 9 facts we try to verify on every heater, the linked pages state 8 for this one.
Not published: a price.
That is a well-documented heater, and it is why our calculator can evaluate it instead of setting it aside.
Common mistakes with this class
Buying at the edge of the rated range
Heater makers publish a volume window and their own guidance says to land in the middle of it. A room at the top of this range heats slowly and runs the elements harder than a size up would.
Sizing from footprint instead of effective volume
Glass and uninsulated surface count as extra volume under the makers’ published rules. A glazed door can move a small room a whole heater class. Run the real numbers, not the tape measure alone.
Discovering the panel question last
The dedicated 240 volt run is regularly the slowest part of the whole project. An electrician can quote it from the load figures on this page before you commit to anything.
