What are the advantages of a fireplace heat exchanger?

Our fireplace heat exchangers:

  • Can be mixed and matched to design a fit completely within their rectangular measurements in ratios of 14”, 16”, 20” or 24”
  • Composed of fully welded, un-coated, un-leaded, un-aluminized, non-galvanized, bare structural-grade, industrial carbon steel, and UL-certified electrical components
  • Built with 100% renewable wind and hydro electricity
  • Consume up to 50% less wood
  • Eliminate the need for expensive climate control systems such as electric heaters, heat pumps, corn or pellet stoves, or central air oil or gas furnaces
  • Pay for themselves after one year of use

How to measure for a fireplace grate?

You will first need to gather the following items: a tape measure, a pen or pencil, and a writing pad.

Remove any items inside or in front of the fireplace that may potentially hinder you from accurately measuring. Then use the tape measure to measure the front and back width of your fireplace.

The final measurement is the depth of your fireplace. Extend the tape measure to the back wall of your fireplace to the front of your fireplace floor.

You want to make sure that all sides of your fireplace grate has 3" of clearance. To calculate those clearances, subtract 6" from both the back width and depth measurements.

For example, if your fireplace has a 22" back width and 20" depth, you will want to purchase a 16" x 14" grate.

What does BTU mean?

A BTU, or British Thermal Unit, is the standard unit of energy used to measure heat. It is used to calculate the amount of energy a heating or cooling system can provide.

The average heat demand of an average-sized home is a 15,000 BTU/hour. At Hasty Heat, all of our heat exchangers are designed with the greatest surface area possible to capture and move the highest percentage of the BTU heat generated by your fire into your home.

How do I clean a fireplace grate?

Begin by using a wire brush. Then use a dry or wet rag to wipe it down.

If you purchased the removable ashtray add-on, you can simply pull from under the grate and empty all the debris in a paper bag or trash bin. 

How often should I clean my fireplace grate?

We recommend cleaning your fireplace grate after every use.

Inspect your grate every year for rust. You may consider adding a coat of heat-resistant paint for added protection.

What is your return policy?

We have a 60-days no-questions-asked return policy for fireplace grate purchases. Fill out our contact form to request return instructions.

After we receive a copy of your payment invoice and inspect your returned item, we will issue your refund less a 20% restocking fee and adjustments made for any missing parts or damage costs.
