How does delivery work?

Ships from Wheeling, Illinois. Free to the contiguous 48 above our free shipping threshold. A small accessory can fall below it and then a flat charge applies, shown at checkout before you pay.

How it arrives. The DROP comes by ground parcel, with no appointment and nobody home. CLIFF, STEEL, HIVE and CORE come palletized by freight, including the wall mounted Mini models: the carrier calls to book a window, someone has to sign, and it is a curbside drop rather than inside.

Stone ships in its own boxes. A heater takes 3 to 16 boxes at 33 pounds each. Stone added from a HUUM heater's own page ships free with that heater; ordered on its own it is charged per box at checkout. The quantity is set by the heater, not the room.

When it ships. The estimate on each product page is the distributor's usual dispatch time for stocked items. Stock moves, so we confirm the current position when you order. Working to a deadline? Ask us first.

If it arrives damaged. Note it on the delivery paperwork, photograph the carton and the contents, and tell us the same day. Report damage within 48 hours of delivery, with photographs and before the heater is installed: that is our window, and because it is shorter than HUUM's 7 days it is the one that applies to the HUUM warranty too. Refuse a carton or pallet that is punctured, crushed or structurally damaged.

Where we ship. The contiguous 48 states. We do not ship HUUM to Alaska, Hawaii or Puerto Rico.

Not included: the electrical work. A HUUM heater is hardwired by a licensed electrician, and the clearances and cable entry are set by the model, so book the electrician for after the heater arrives.

What does the warranty cover?

Private use. 3 years on electric heaters, wood stoves and controls, and 1 year on spare parts, running from your purchase date. Keep the receipt and your electrician's invoice.

Commercial use. 1 year on all of them. HUUM treats it as commercial if a business uses the product commercially, if a private owner uses it commercially, or if a private owner runs it more than 1,500 hours in any 12 months, so a gym, studio or rental is commercial from day one.

What is covered. Defects in materials and workmanship. HUUM decides whether to repair, replace, refund or, with your agreement, reduce the price, and it arranges and pays for any transport it needs. A replaced part does not restart the clock.

Excluded, the ones that matter most. Heating elements, all sensors, sauna stones, accessories, and a wood stove's door glass and ash grate. Also normal wear, damage from poor ventilation or constant damp, power surges and overheating, non-HUUM parts fitted without written approval, and a heater that was the wrong size for the room. Until it is installed it must be kept indoors, dry, ventilated and above freezing.

Two conditions decide most claims. The heater must be installed and connected by a licensed electrician, to HUUM's manual and your local codes, and HUUM can ask for proof. Damage found on delivery must be reported to us within 48 hours and claimed with photographs before the product is installed. Any other fault: report it within 30 days of finding it.

If the fault turns out not to be covered. HUUM's terms let it charge for the work of diagnosing it. We will tell you as soon as HUUM tells us.

Who handles it. HUUM OU in Estonia is the warrantor and we file the claim for you, so you deal with us rather than with Estonia. Call (888) 500-5675 with your order number, the model and its serial number and photographs.

What if I need to return it?

30 days from purchase. New, uninstalled and resalable, in the original packaging with all parts. A heater that has been wired in, fired or loaded with stones counts as installed and cannot go back, and so does a control that has been wired in.

What it costs. Full credit for the product, less a repackaging fee of 20 to 50 dollars depending on the item. There is no percentage restocking fee on a standard return.

Who pays the freight. You do on a change of mind. We cover it when the cause is shipping damage or our error. Shipping you paid at checkout is not refunded on a change of mind return.

Damaged on arrival. A different and faster process. Note it on the delivery receipt before signing, photograph the carton and contents, and call us the same day. Report it within 48 hours of delivery, with photographs and before the product is installed.

Stones and spare parts. Stone is sold by weight and is not returnable once a box is opened. Heating elements, sensors and other spare parts cannot be returned once fitted.

Cancelling before it ships. No fee at all before we send the order to the distributor. After that an administrative fee of up to 5 percent may apply, and we waive it when we are not charged ourselves.

To start a return. Call (888) 500-5675. A Return Authorization number is required before anything ships back. Refunds go to the original payment method within 7 business days of the return being received and inspected.

The main module is the box that switches the heater. It mounts outside the hot room, the display panel plugs into it, and the temperature and door sensors wire back to it. This is the Wi-Fi module on its own, sold as a service part rather than as a complete control.

What it does, and what it does not

The module carries heaters up to 11 kW by itself. The HIVE 12, 15 and 18 draw more than that and need the UKU extension box alongside it, which is a separate part.

It is sold without a display panel, without sensors and without cables. If yours failed and took nothing else with it, this is the part you need. If you are replacing a whole control, buy the control rather than the module.

Where it is allowed to go

HUUM's rule is outside the sauna room. Where that is impossible the manual allows it inside, no higher than 4 inches off the floor, at least 6 feet from the heater, ideally under the bench. Its maximum working temperature is 122 F, which is why it never goes high on a hot room wall. Leave the access panel reachable, because it has to be opened to wire anything into it.

Check the generation before you order

This is the module for HUUM's UKU 4.1 generation, which is the control we sell. HUUM uses different part numbers for the 4.2 generation. The rating label on your own module tells you which you have: the photograph above shows where it reads UKU WiFi and the version, and the two minutes it takes to look are cheaper than a wrong part.

A heating element is wired inside the heater, so this is a job for the licensed electrician who connected it, not a home repair. HUUM also asks for all of the elements in a heater to be replaced at the same time, because a new element next to worn ones ages quickly.

Questions buyers ask

How do I know whether I need the module or the whole control?

The module is the box that switches power. If the panel lights and the heater never comes on, or the module shows no life at all, the module is the suspect. If the panel is dead or cracked, that is the panel, which is a separate part.

Does it come with a display panel?

No. Module only. The panel, the sensors and the cables are all separate parts.

Will it work with my UKU 4.2?

No. This is the 4.1 generation module. HUUM lists different part numbers for the 4.2, so read the rating label on the module you are replacing.

Does it work with UKU Local as well as Wi-Fi?

This is the Wi-Fi module. The Local control uses its own module, so order to match the control you have.

Can I fit it myself?

No. Mains wiring lands in this box, so the licensed electrician who wired the heater should do the work.

Do I need the extension box too?

Only if your heater is over 11 kW. The HIVE 12, 15 and 18 need it. Everything smaller runs on the module alone.
