We are switching from an ugly oil Monitor 2400 to a nice, freestanding, wood-stove-style propane heater. We are in Northern Canada and deal with -40C so looking at 2000ft2, 35-40,000BTU. Two things: general input on Lopi Cypress vs Regency U38E/39 or Napoleon Havelock/Haliburton? Thanks! We need it ASAP so all advice appreciated.
