    Q:Does this unit fit in a 2x4 wall? 16" on center? The specs say "Dimensions: H 21.5 in, W 16.8 in, D 5.3 in", but I think that is the shipping box dimensions.

    Answer This Question

    A:  HI Cold Guy, The opening for this unit needs to be 19 3/4 high and 14 1/4 wide and 3 5/8 deep. This unit is designed for attachment between studs to avoid any vibration and noise caused by loose mounting. Glen Dimplex Americas Customer Experience Team.

        Q:Since the specifications say 20 Amp, is installing a dedicated 20 Amp breaker sufficient? Also, does this unit come with a male cord to plug in? Thank you.

        1 Answer
        Answer This Question

        A:  Hi Scott, 20 amp breaker dedicated will be what you need for this one unit. No this does not have a plug you need to hard wire it in. Glen Dimplex Americas Customer Experience Team.

          I bought 2 of the heaters. 1 out of 2 the fan doesn't work. And returned. Other one's fan is working. However, it just produces very mild heat. I've do some research if it is it.

          The heater fit into the recess we already had and was relatively easy to install. It heats very well, but it is noisy. Unfortunately, it is in our kitchen so I am having to get used to it.

          This is a piece of crap, it doesn't heat. It will turn on for a couple minutes then turn off. You couldn't heat a 100sq ft room with this piece of junk.

            As with another purchaser, my unit would only activate a few minutes then turn off before heating the 400sq ft room. I contacted HD who referred me to Dimplex. I explained my issue and Chad informed me I would have to take it up with HD for a return or replace. but they are sold out and I am stuck with a faulty heater until they restock. Wouldn't recommend Dimplex at this time.
