Meet Our Unique Forced Air; Hot Air (Water-Less) Models

20-year ON-SITE WARRANTY

1.

20-Year ON-SITE Warranty

- VERY IMPORTANT that you won't have to pay shipping to get it repaired! (10-years on water jacket)
430-ton Press Brake

2: 430-ton Press Brake

We are the only manufacturer that uses a press brake to form a firebox and water jacket; both from 1 piece of metal.

Most everyone else uses 6 flat slabs of steel, with no inherent strength and that requires 12 welds because welds are the weak spots.

This new firebox and water jacket is formed using a 430-ton Press Brake, meaning less welds which means less potential for leaks because leaks often start at welds; Almost as few welds as on a cylinder; Only 4 welds vs. 12 welds on a typical firebox. Three times less! 

3: Not only is the firebox thicker; the water jacket bottom is THE SAME THICKNESS as the firebox because it is the most vulnerable part); 3/8" standard and the 1/2" THICK firebox option gives you a HALF INCH THICK water jacket bottom as well!

NO ONE ELSE DOES THAT - ANYWHERE!! 

Upgrading the thickness of the water/air jacket may be a better option, where we make your water jacket 1/3 thicker, upgrading it to 1/4" thick, which is what I did on my personal boiler. 

No Proprietary Electronics and Circuit Boards

4: It is the best boiler because it has ALL Off-the-Shelf PARTS; nothing proprietary that you have to get from us.

5: It is the best boiler because it has No electronics; NO circuit boards, NO computerized parts (like the part on the left and on the Wood Master and Central Boiler and many others)! 

Smartphone Monitoring

6: Do you really need a Smartphone or Laptop to monitor your outdoor boiler?

I say that you should not have one if you cannot go outside and open the rear door and look at the thermometer and glance at the water gauge to see what is going on!

It is just something else to go wrong with a lot of extra expense that seems to be never covered under warranty.  They always say that a power surge took out the circuit board and you get stuck with a $300.00 bill and the technician's cost to install it.  

Not so with Hypro Therm.  Every part on our boiler is available almost anywhere and everywhere; on eBay, at Grainger, your local plumbing supply; even in Canada!

One Inch Solid Steel Grates

Solid Steel Grates

7: One-inch thick Solid Steel grates are a stronger option, resistant to bowing and deformation like you may get with steel grates.  We purchase these from a foundry that labels them as coal grates, and they do well.  Shaker grates, are cast iron and are available as an option, mostly for those folks burning a lot of coal, where the coal is inclined to have clinkers.

Our smallest models have one grate, the next two sizes up have two grates and our largest models typically have three grates.  

Pull-out Ash Tray

8: Pull-out Ash Tray

Most manufacturers make you open up the firebox door to clean out the ashes with a shovel.  You will quickly find out that you are not going to get anywhere near the firebox because it will be 800 F or more!

They want you to open the firebox door and you will need to leave it open to let the heat out and I call that wasting heat.  You will need to kill the fire to be able to shovel out the ashes and then you have to start a fire again, in the dead of winter.

With our furnaces you do it the easy way.  Even with a fire raging, you can pull out the ash tray, dump the ashes into a fire proof container and slide the tray back in without missing a lick.  Two handles on the ash tray make it easy.  Every ash tray is the same length as the firebox.

9: It is the best boiler because it has one pump installed WITH flanges; many others don't give you any pump PLUS we give you an extra set of ports for another pump to heat another building.

10: They all come pre-wired with a reliable RANCO aquastat as shown below.

Hyprotherm Front Loading Boiler

ALL MODELS
except for Econo 85

- Full sized rear door for easy access!
- Totally pre-wired with Ranco Aquastat, fan switch, 4 outlets, a pump, a second port for another pump, and a 75 CFM forced air induction fan .
- This blower (see next photo) feeds oxygen from the bottom, up through the grates just like a blacksmith's forge.
- Water level gauge and an analog thermometer included (upper left)
- Second set of ports for another pump (below thermometer).
- Built in hot water coil to heat your domestic hot water (saving you $35-$65 per month plus up to $400 in parts costs).
ASH TRAY CLEAN-OUT!

Just $400 more than the smaller FLRH-100!

11: It is the best coal and wood boiler because it has a 75 CFM blower in the back, to blow air (oxygen) up through the grates, just like a blacksmith's forge! Absolutely necessary for coal and better for complete wood burning.

With an inexpensive solenoid activated damper, as shown in the photo below.

You get a real nice hot fire, so that there are no unburned pieces of wood or coal left over (like on a Central Boiler).

75 CFM Forced Air Induction Blower

75 CFM Forced Air Induction Blower

Feeding oxygen up through the grates (which most boilers don't have) from the bottom, just like a blacksmith's forge with a solenoid activated damper, so that no wood is burning (being wasted) when the aquastat turns the fan off!

Two return ports shown!

12. Our boilers have the best of the newest state-of-the-art insulation; a combination of ceramic wool and a product from Knauf. This was done after insulation engineers told us that fiberglass insulation was only good for a home, where you are trying to keep 75 degree heat in.

It is a different story when you are trying to contain 800 + degrees in a firebox; thus the new and better insulation. 

We put a layer of SolarGuard on top of the insulation from Knauf to give R-10 additional insulation by using a reflective barrier that controls heat in 3 ways; reflective, radiated, and conductive.  See this video for a demonstration of its great properties.

SUMMARY:

Our boilers have flat cast-iron grates standard, a 3/8" thick firebox; that is 50% thicker than common 1/4" fireboxes OR a half inch thick option; 100% thicker than common 1/4" fireboxes) and includes a pullout ash tray for easy clean-outs, the standard pump, a second set of ports for another pump or building and the built-in heat exchanger for the domestic hot water - as well as an automatic, solenoid activated damper on the forced air fan/draft, in the back and a chimney cap AND last but not least, a 3/8" or 1/2" thick water jacket bottom option; the most vulnerable part; now at least 3 times thicker.

Remember, there is no negative to getting a bigger furnace because it is not like purchasing an air conditioner where if you get one too big, it becomes inefficient. It is simply like getting a bigger fuel tank so that it will hold more fuel and you will need to fill it less often.

** Most companies do not even have grates or a way to clean out the ashes, other than opening the loading door and you are not getting anywhere near it because it is 800F - 2000F. So you have to let it cool down from and then restart a fire - in the dead of winter!

This is how we do it! A removable tray! The EASY WAY!

Remember, there is NO SALES TAX when we ship out of state!

Remember, the 20/10 year parts AND labor ON-SITE warranty, which is probably the best feature because at least 85% of the manufacturers out there require that you ship the furnace back to the factory to get it repaired. Then they have to ship it back to you and while the repair may be free, they charge you for the shipping both ways AND you have to disconnect the furnace, reinstall it and be without it for at LEAST 2-6 weeks.
