Will stainless steel hold up longer then mild steal? Does it corrode faster?
Yes it will hold up longer than mild steel. You can expect a typical well-maintained mild steel unit to last anywhere from 7-12 years on average before needing replacement. A well-maintained stainless steel will not corrode faster than mild steel. We use a high grade 409 stainless steel treated for applications to withstand high heat.

What is the difference between 304 and 409 Stainless Steel?
409 Stainless is specifically made for high temperature situations, has better heat transfer and warps less then 304 Stainless Steel while 304 Stainless Steel tends to corrode slower but has poorer heat transfer.

Why don’t you offer a duel-fuel option for your furnaces?
While this option may look appealing at first glance, it really doesn’t offer anything most customers don’t already have in the form of an existing indoor heat source. When installing a furnace you can set the existing heat source as the back up as simply as using another thermostat. Then if there is a power outage or a pump failure, there is still heat for the customer whereas the dual-fuel furnace would give you no back up.

What is the difference between a forced air and natural draft furnace?
The difference is how the air to stoke the fire is brought in the firebox. Natural draft furnaces open a damper that allows air to draw in to the firebox directly from the outside. Forced air furnaces use blowers to blow air directly in to the firebox with more control then natural draft furnaces while also having the option of using variable speeds to better control your firebox burn rate. They also allow the furnace to burn hotter.

How do the rocker grates work? What makes them worth the money?
Rocker grates are exactly what the name describes. They allow the user to burn wood, coal and cob corn (or a combination at the same time). They also make it extremely easy to keep the fire box clean and well-maintained by having the ashes fall in to the ash pan. This feature is probably the most popular feature on the market right now. Many manufactures are trying to copy the idea with little success.

Why is it that this furnace can burn multiple fuels (wood coal, corn) and others can’t.
What allows our MF-Series to burn multiple fuels is the air being blown under the rocker grates and below the fuel being burned. Our MF- Series works particularly well with lump coal and cob corn.

What makes the Heatmaster SS a better buy then the other furnaces?
What makes our units above the competition is the bang for the buck. Customers get the most square footage, the most features and the best quality for what they pay. Our stainless steel furnaces are priced at the price of mild steel furnaces and offer more of the features customers want to avoid distributors and sell dealer direct savings the customer hundreds of dollars. Bottom Line- They get more for the money they pay.

What is the difference between a pressurized and non-pressurized furnace?
Pressurized furnaces are sealed systems that operate on higher temperatures and use steam power to heat. They can generally put out more BTU’s but are made only for large industrial purposes. While they do put out more BTU’s they offer more danger to the customer and cost more money to purchase and maintain because you need a certified boiler technician to install and repair the furnace. Pressurized furnaces are usually only available in industrial size models.
