This allows for efficient operation while offering the most flexibility between natural gas and propane in each unit.

One of the best purchases I've made.

from Montgomery, AL on 01/11/2015 – Verified Buyer

Excellent product,keeps a very large living room warm.A ceiling fan is really helpful to circulate the air.I live in Bama with a heatpump with strip heat backup.This is a helper to the heatpump to keep strips from coming on,saving $$$$$.I've had it for over a year now without any operational problems.The only two things I did not like about unit is on my model,it does not have a mark at the T'stat to set it.I contacted Thermabast and they said straight in front is where the setting should be.They said that was an oversight and would be corrected on future models.Another thing , it is factory set for propane.I have natural gas and did not have tool to switch it over,Thermablast sent me one very quickly :) .Thermablast support is great.Trust me , this is a very good spaceheater.

Puts out good heat!

from Prescott, AZ on 09/21/2015 – Verified Buyer

If you are using in a closed space you will also need a dehumidifier. We put this in a cabin because it burns clean. But our windows condensed on the inside of the house.

Questions & Answers

Q: "Would this heater be ok for a space 20' x 12'?"

– Jonali from Wayfair on Mar 26, 2014
Q: "My garage is 20' x 14' x 8'. I was wondering how fast it would take it to heat up? Does the heater put out an odor at all, give out carbon dioxide, or a propane smell? The garage is attached to our house."
A: The unit does not need a vent outside. This heater is very similar to a gas stove which also does not have a vent. The safety features to allow this kind of product is the ODS system or Oxygen depletion sensor. This sensor monitors oxygen levels and will shut the unit down in the event of an unsafe condition. It will also not allow restart unless the oxygen levels return to safe levels. This has a pilot light which is lit by a piezo igniter. It heats an area of 1100 sq. ft.
