Heating a Mudroom

nreevesFebruary 27, 2013

We have an existing breezeway/mudroom, it is 15'X8' and attaches the garage to the kitchen. It also has a backdoor to the yard. Both sides have 2 large windows that are directly across from one another. It is on a poured slab. It has insulated walls with drywall and wood paneling. It is ugly and we don't use it because it is unheated and we live in Michigan and it is freezing out there. The plan is to put in built in bench/open locker/hooks, tile the floor and really utilize this awesome space. Before we do anything we need to figure out how to heat this area. I have looked into some options and need some advice... in-floor heating, wall heaters, baseboard radiators, radiant panel's... my head is spinning! I need some opinions! Most likely we will have to do electric, I don't think it is realistic to do a hot water system, oil, propane etc. I don't think it is smart to run ductwork from our gas furnace. I need to know what is the most efficient way to keep this space comfortable (60 degrees maybe) all winter long. Any input would be appreciated!

I would recommend electric in-floor radiant. I would also strongly recommend a Schluter Ditra decoupling membrane under the floor tiles and over the in-floor radiant to reduce the risk of cracked tiles. I would also recommend an epoxy grout that is both waterproof and will not stain or discolor.

Since you have gas, you might consider some sort of wall-mounted gas heater, vented or ventless.

Your plan sounds great.

I agree with weedmeister, a smallish gas wall mount should easily handle 120 sq feet. I'd also get vented rather than unvented since the room is mostly closed up. Your placement options may be a bit limited by code requirements for the exhaust duct, they often state minimum distances from opening windows and doors.

Heat using any kind of gas will likely be cheaper to operate than any kind of electric radiant heating.

Thanks for the ideas, I was recently looking at this http://www.wayfair.com/Mr.-Heater-20000-BTU-Natural-Gas-Vent-Free-Wall-Space-Heater-MHVFB20TB-NG-MXH1055.html. It is so cold in there I wonder if the heated floor would be enough to keep the room warm... my brain is so torn LOL!

Radiant floor heating will work. The main issue is that it will take quite a while to heat up.

Having windows with a U factor If you use forced air heating, the space will heat up quicker than radiant floor systems. If the slab is not thermally broken/ isolated from the ground or the windows are losing heat, the heater will be on quite a bit.
