Customer Questions & Answers

Can you replace a section of baseboard with this unit?

I have a section of baseboard hydronic heat in my kitchen, and would like to get rid of it to use that wall space for cabinets. Can you just cut out the section of baseboard heat and pipe this unit in its place as a part of the home heating zone?
Asked by: Jeebs
No you can not just put it in series where the base board was. The connections of the kick space heater are 1/2" where as the baseboard is 3/4". Thus if you pipe it in series your will reduce the flow rate on the entire zone to that of 1/2". Kick space heaters are piped in what is called "parallel". You pipe the kick space heater as a 1/2" loop off of the 3/4" loop using what are called "mono flow, Venturi or Scoop Tee". By piping it this way, the flow through the 3/4" loop draws the proper amount of water through the 1/2" sub loop due to t the pressure drop created by the 3/4" x 1/2" scoop tee installed on the down stream run. You may do a google search on monofow piping in case you can;t visualize what I am saying, or give me a call. Chris 978 651 3301 It is not as complicated as it sounds but the system will not work properly any other way. You can often still accommodate the installation you want using this piping configuration.

Where does it draw air from? The upper part of the vent?

Where does it draw air from? The upper part of the vent?
Asked by: SkierGuy
The air is both drawn in though the front and is discharged through the front. It does not draw air in from above. This may appear counter intuitive to many however you have to keep in mind that 4000 BTU's is not a tremendous amount of heat. It would be equivalent to the heat given off by roughly 8 adults standing there. So the purpose of this unit is to put 4000 BTU's into the room air with as little notice as possible. Thus it will not act as a blow dryer. It is intended to replace replace what leaks out the walls in that area.

does the front panel come off for cleaning the coils?

does the front panel come off for cleaning the coils?
Asked by: Bernie
No. The unit does not easily disassemble for cleaning. I vacuum mine periodically from the outside only.

where is the electrical connection

Asked by: vinny
There is an integrated junction box in the unit on the left hand side as you face the front. Bring your Romex directly into the box as you would any junction box, and terminate it inside the junction box, which is easily accessed from the top of the unit.

Customer Reviews

2000 Series 4,000 BTU Brown Hydronic Kickspace Heater (Not Electric) is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from great kick space heater... Got one for our kitchen and it is quiet and warm. It has two fan speeds, normal and turbo. Super easy to install, supply and return and easy wiring hookup. The air vent is easily accessible from the front of the unit. We've had out for a few years now and it it hasn't failed. Not much more to say. Good unit.

Rated 5 out of 5 by from Quiet, compact and efficient. This heater is easy to install, too. This unit is an exact replacement for an under-the-stair heater over 20 years old. The old one was sold under the VRV Products name. This new one is Smith’s Environmental. Same unit, though. This product is heavily made. No frills, but no shortcuts, either. The older one lasted 20 or more years. They look identical, so the new one ought to last as well. There’s a handy hi/lo fan switch, but I just leave it on high all the time. It pulls air in from the top and blows heated air out the front. The fan runs quietly and automatically. When your boiler sends hot water to this unit, the fan turns on. If there’s no hot water present, the fan goes off. Simple. There are no instructions to speak of. Plumbing is easy – two ½ inch copper pipes. They tell you which pipe is the inlet (lower) and which is the outlet (upper). I soldered on copper fittings and used unions to connect to the heating system. You can use PEX, as well, which may be easier. There’s an easy-to-reach bleeder valve for getting air out of the heater after installation. Electric is simple – black wire, white wire and a ground lug. You will need two wire nuts and a standard 3/8 inch through-hole clamp, not supplied with the unit. It took me about an hour to remove the old heater and install this unit. It worked right away and is heating the space now. I am pleased with this purchase, would recommend it, and happy to have found it at Home Depot.
