Rated 3.9 out of 5 by 7 reviewers.
Rated 4 out of 5 by Warm & Toasty This equipment is very efficient. Not difficult to install. We are using it to heat four rooms downstairs and the two bedrooms upstairs. It is located in the frontroom. It doesn't blow cold air, just warm air. The rooms are seperated by walls and doors, yet there is only a 4 degree difference from one end of the house to the furnace. Very happy with the relatively quiet operation and even heating throughout the house. It has optional front and side venting that I think we will invest in later. November 20, 2010
Rated 4 out of 5 by This product was as described. This furnace puts out a lot of heat. It is a little loud. November 21, 2013
Rated 5 out of 5 by Just the right size for my basement. This is a furance made by Williams. It replaced one that was the same size and manufacture that I had for 25 years. The blower moter failed and they did not have a replacement. But 25 years of trouble service is great! I think ths one will last just as long. November 20, 2011
Rated 4 out of 5 by Great product for the price. Installation straight forward. External thremostat and blower fan included greatly add value Using it in a 900 sq ft apartment. Mounted it in the main living room due to convenience of hookup and access to natural gas. Bedrooms are a few degrees cooler but very comfortable. As an added bonus, the concrete floors in the main room stays warm resulting from the bottom forced heat from the heater. December 12, 2013
Rated 5 out of 5 by Good heat a very good product that provides a lot of heat right away and is not noisy February 18, 2014
