CLIFF is a slim electric sauna heater with remarkably small safety distances, which makes it perfect for saunas with limited spaces. Thanks to its well-optimized structure the safety distances from the walls are brought down to just 6 cm with smaller models and to 24 cm with larger models. CLIFF heater also comes in an even slimmer 3.5 kW wall-mounted model which is particularly suitable for very small sauna rooms.

For what size saunas are HUUM heaters best?
There are options for both small and large saunas with volumes ranging from 106 Cu. Ft. - 1236 Cu. Ft. among the different HUUM heater designs (Cliff, Drop, Hive)
How do I choose the correct heater output for my sauna?
The output of your sauna heater should be determined by the size and insulation of your sauna room. To heat approximately 50 Cu. Ft. of your sauna room it will require 1 kW of power on average. As an example a 6' x 7' x 7' sauna room should require a 5 Kw heater. (252 cubic feet divide by 50 = 5.04).
If your heater is too small in proportion to the volume of your sauna room, the sauna will heat up too slowly, not enough steam will be produced and the heater will burn out more quickly. With this in mind, if the heaters you are considering are not of the exact size required for your sauna room, err on the side of purchasing one that has a greater heating volume than what your sauna requires. If your heater has a thermostat and is used correctly, a heater that is somewhat stronger than what is required will not cause problems.
It’s also good to note that electric sauna heaters turn off once the desired room temperature is met. This means that a larger heater simply works less than a smaller heater so there is virtually no energy savings by purchasing an under sized sauna heater. If in doubt always go up a size.
Your sauna rooms insulation is the second key factor to consider. For an outdoor sauna or a sauna built on outside walls with little to no insulation (brick, tile, glass, wood etc.) you may want to purchase a larger heater than technically required. A good rule of thumb to follow is for every square meter (10.75 square feet) of a wall that does not have insulation, increase the volume by 1.2 cubic meters, or 42 cubic feet. If you live in an area where the weather is very cold it would also be good to consider choosing a larger heater option.
How long will it take to heat my sauna?
If your heater is the proper size for your sauna room, it will heat up to 80 degrees fahrenheit in one hour, at a rate of roughly 10 degrees per 8 minutes.
What kind of stones can be used with HUUM heaters?
We recommend using sauna stove stones that are rounded and natural. We have light grey olivine diabase stones with a high heat capacity by HUUM in our inventory. Because decorative stones are readily broken, they should not be used in your sauna heater.
Who can install my heater?
The cabling and connection of the heater to the power source should only be done by a licensed professional.
What kind of wiring will I need?
Installation instruction for cables can be found in the product installation manuals found under the Installation Tab on our site. A licensed electrician is required to install the cables.
STEAM LIKE IN A TRADITIONAL SAUNA
HUUM heaters are built by using very small amounts of metal so that the heat comes mainly from the stones and only very little from the metal. This way it can maximize the good negative ions from the stones, like in traditional saunas, and keep the positive ions from the metal at a minimum. Together with a high stone capacity this is it’s secret to healthy, mild and long-lasting steam.
CRAFTSMANSHIP
HUUM heaters, control units and other products are made with care entirely in Estonia. The seemingly simple design of their heaters requires a quite complex production process. Because of this they have partnered with Estonia’s leading metal work companies to guarantee the best possible quality in each step of the production process.
Every heater is made of stainless steel that goes through shot blasting and acid treatment in order to get it’s final refined appearance. Quality, precision and innovation are at the core of all HUUM products.
INNOVATIVE CONTROLS
The innovative electronic solutions of HUUM remote controls and app are smart on the inside and beautiful on the outside. They are the creation of some of the bright minds of HUUM’s hometown Tartu. It took five years to develop and improve the technology that they currently use. Oshino Electronics Estonia takes care of the production of the remote controls, which come in wooden and different colored plastic cases. The wooden cases are handmade out of thermo-treated ash, giving each one a unique look.
LESS PACKAGING
HUUM uses as little packaging material as possible to reduce unnecessary waste and use recycled materials for their products where possible. For example, the case of the main module of the control unit is made of recycled plastic. In every way HUUM is driven by excellence and forward thinking.
