Description

Kickspace heaters are the space-saving alternative to hot water baseboard. Designed to fit inconspicuously under a cabinet, in the floor, on or in the wall, kickspace heaters are ideal for hard to heat areas such as foyers, kitchens, and bathrooms.

Hot water from the home's boiler is circulated through the kickspace unit and the fan gently blows heated air into the room. The homeowner simply selects the fan speed, then the unit turns on and off automatically according to heating demand.

Twin-Flo III + kickspace heaters are your ideal solution wherever space is limited:
  • Under Cabinets
  • In Kitchens, Baths, and Foyers
  • Under Stair Risers and Windows

Most Liked Positive Review

The Good & Bad

I bought the smallest of the 3 units. The Good: Does the trick. On Low speed is quiet. Needed foot room in bath Rm and it is out of the way just like it needs to be. The Bad: On high it is loud. When installing you must connect electric and close elec access panel before drilling holes and bolting down unit (this is not mentioned in instructions). I have PEX and needed to solder Pex adaptors (no biggy but thought I would mention it). I foam insulated my bathroom and installed a [slightly] heated floor. If I still had fiberglass insulation I probably would not be able to run it on low speed. In that case I would have bought one of the larger units so I could run it on low speed.

No built in air bleeder valve

I installed the unit and it didn't get hot when I tested the system,it was bound with air so I had to install a bypass valve and bleeder valve and then it started working . The quality is okay, I bent up the housing while trying to remove the knockout for the electrical connection. I wish I bought a different brand with a built in air bleeder accessed from the front of the unit.

Q: i want to install one of these units in a second floor bathroom. My boiler (hot water) has a recirculating pump and is located in the basement. (There are three floors) Can I utilize the two pipe system that I have in series, or do I have to zone this thing off with its own recirculating pump? Thanks

Q: What type of electrical outlet I need to install for K42 Kick Space Heater?

This unit gets hard-wired by an electrician to an 115V circuit. There is not a 'plug' or 'outlet' involved.

Was this review helpful to you?

This unit has no power cord and uses minimal amperage to run the fan motor. It is hard wired to any 110 VAC circuit. I would suggest using a GFCI circuit if unit is being used in a wet location.

Was this review helpful to you?

This unit does not plug into an electrical outlet. The unit is hard wired and the junction is contained within the unit. You will need to run a wire from a nearby junction box. Current drain is very small.

Check the wiring diagram on the heater. It’s a small fan with little draw, less than a bathroom exhaust fan. I used 14/2 wire on mine and haven’t hd any issues.

A single gang will work fine. You can even run a new wire directly from another outlet if it's nearby. It's only to run a small fan in the unit, so it won't draw much power. Sent via the Samsung Galaxy S® 5 ACTIVE™, an AT&T 4G LTE smartphone

Sure, you can i would just check to see if there is some local building code that say you can't.

Was this review helpful to you?
- T.D. Ball

Once you buy it, it's yours and you can do what you want with it. Attach any type of plug you like. The reason it is normally hardwired is due to access and the unit isn't something one changes out. Sort of like a disposal I guess. Many are wired with a plug but few are seldom, if ever, changed out.

Q: Can this unit be installed vertically beneath the floor (i.e., not using the optional floor kit which installs at an angle)? The reason I ask is the space between the joists is only 14" x 14", so the floor kit won't fit. However, I do have enough vertical space to install it vertically -- if that's possible? Alternatively, can this be installed on its side? I have another possible space for this in a chase, but it wouldn't fit flat, only on it's side.

I don’t see why not, provided you have adequate airflow.

Was this review helpful to you?

I don't see any reason this unit can't be mounted any way one wishes, upside down, backward, or any other way one can think of. With that in mind, this unit is made to mount under a cabinet such as a kitchen sink where space is limited. You should be able to mount this unit vertically, just keep in mind that the fan is a long roll squirrel cage type so you will need to cut a vertical slot for the vent where the unit is to exit the cabinet that will be the same dimensions as the unit.

Was this review helpful to you?

No reason it cannot be mounted vertically; it has four mounting points and as long as the water lines are purged of air and the inlet is not blocked you should be able to mount it in just about any position.

Q: Will this heater fit inti a cabinet that is only 18 inches wide

Yes, it will . unit is 12 - 1/4 “ wide Roger Dicks Sr.

Yes, if the space is at least 14 and 1/2 inches wide, to accommodate the 90 degree sweat fittings.

Was this review helpful to you?
-

The unit itself is only 12" wide, but the heat feeds in from the side. I would think that 18" would be enough room to run a flexible line. You may need to use a 45 or 90 degree elbow on the unit to reduce the bend in the line.

Was this review helpful to you?

Wish I could, but installed it at a different location and don't e remember the dimensions of the space. I won't be there for awhile. Seems like they gave pretty specific instructions with the purchase. Replying because I do like the heater a lot.

Was this review helpful to you?
-

Maybe. It will depend on the cabinet construction and how much clearance you have to get the plumbing and electric to fit as well. If you have good height under the cabinet I would say more than likely you will be able to get it to fit. A trick when I have installed these is make the bottom of the cabinet removable before you install the cabinet so you can get to the heater unit later. Hope this helps.

Was this review helpful to you?
- T.D. Ball

The heater dimensions (found in the specs) are 12-1/4" wide by 3-7/8" high by 12-3/4" deep, so unless there is something reducing the space under the cabinet it should fit with room to spare.

Q: I have an outside corner in a kitchen addition that I would like to install the K42 as an in floor unit. Is there a drop in the BTU rating when it is installed in this manner? This is really the only installation option for this part of the kitchen given our design.

I installed the unit in-floor in a bathroom and didn't realize any reduced heat output nor am I aware of any reason it would occur.  The only problem I had was the in-floor enclosure was made to exactly 14.5".  Anyone that has worked around rough framing knows every 16" oc space is not exactly 14.5"- some a bit more some a bit less.  I had to really persuade the unit into place.  That was ~5 years ago so maybe they improved the enclosure and now it's more like 14".

Was this review helpful to you?

The heat output in BTUs depends on the temperature and the flow rate of the water to the inlet of the unit. So if "outside corner "means a long distance from the heater hence lower temperature water then BTU output would be directionally lower. Sent from my iPhone

Q: Hi, I am looking at the k 42 kick space heater. I may need it to replace 3' of base board heat that was removed. It was 3/4" copper tube through the 3' of fins. Is this a satisfactory unit(size wise) for that? Thank you.

3/4 inch baseboard is uually 500 BTU per foot so 3 feet is 1500 BTU and the 42K is 4200 BTU so you'll have plenty of heat.

I replaced a 6’ run of baseboard heat with this unit in my kitchen…works great.

Was this review helpful to you?
- RennovatorMan

Your 3' of baseboard is probably rated for 1500-1800 BTU. The K42 will deliver about 4300 BTU with the fan on high, 3600 with the fan on low (no rating info given for case with fan off, but probably pretty minimal). (180 degree water temperature). Depending on your system design this may or may not be a problem; if the occupant is okay with turning the blower on/off then it should be fine. Alternatively a line voltage t-stat can be installed to control the blower. Note that head loss will be higher which may impact circulator performance.

The K 42 btu output is 1,480 to 5,240 while 3' of baseboard heater is around 1,290 to 1,770 btu depending on water temp and flow rate. Of course if you want to run the fan you will have to add an electrical connection..

I had a similar situation and replaced 3' of baseboard heat with the k42 kick space heater. The blower on the unit circulate the heat into the room quicker than the baseboard unit. I feel I get more heat from the k42 than I did from the 3' baseboard unit. I would recommend this as an adequate replacement. Glenn Dalton
