Fireplaces are fun...until you've been thinking about them for fourteen hours straight. We are having a tough time choosing a wood fireplace insert and would be so grateful for your advice. We currently have a traditional brick fireplace with an unusual opening size, 48" wide by 30" high. Our wood mantle only has 36.5" clearance from the hearth, which makes it really tough to find a large unit that won't cause a fire (though we're open to using a heat shield if need be). We also need to be able to put up a protective shield around it because we have a little one who I'm sure will be mesmerized by the fire. We'd like to get a unit that has as much maximum viewing area as possible, and budget is a big concern. We need a minimum BTU output of 25,000 (just heating the lower level our home, roughly 1,600 square feet, with 6'8" ceilings and some existing heating in place). Despite our relatively low BTU requirements, we don't want to put a smaller unit in our large fireplace, so having a much higher output than needed won't be an issue as long as we can adjust output. What would be ideal is something that has a long burn time and the ability to notch it down a lot on days that are just a little bit cold. We are considering the VC Merrimack, Napoleon EPI3C, and, the current front runner, the FireplaceX units (either 33 or their largest unit, which, oddly, has smaller surrounding cladding than the 33, requiring us to build a custom one). The Clydesdale seems to be the best reviewed among the larger units we looked at (great viewing space, good performance), though it is also among the more expensive (starts around $3400 just for the unit, it seems), so wasn't in our budget range. Are we missing any possible units that will fill our fireplace nicely? Are we misguided in any way? Many HUGE thanks in advance for your guidance!
