How Quickly Will FREEZE Damage Destroy Your Outdoor Furnace?


How Quickly Will FREEZE Damage Destroy Your Outdoor Furnace?



The answer is this: Very Quickly - in some cases less than 24 hours! Naturally, this depends on outdoor temps, wind, insulation, and many other factors, but if you have a catastrophic failure over the weekend, you may not be able to prevent freeze damage by the time you get replacement parts.

Winter is not even HALF OVER yet. BE PREPARED with your spare electrical components!


Remember, all outdoor wood boilers are designed to outlast their electronic componentsPumps, fans, solenoids, and high limit switches will all fail during the 20-40 year life of an outdoor wood burning boiler (perhaps a few times!).


An investment in the Emergency Preparedness kit will prevent a major disaster for you that could cost you thousands of dollars to fix. Remember, that these replacement parts will be needed eventually anyway, so SAVE YOURSELF from high-cost freeze damage!

When you have a catastrophic failure, will you be ready?

All Outdoor Boilers are designed to outlast their electronics. The standard "Emergency Preparedness Kit" contains four items:

- Pump

- Blower Fan

- Solenoid

- High Limit Switch

The blower fan must be the correct size to match your boiler. 

We almost always recommend the Brute Pump (see article "Pump Size Matters" HERE)

In many cases, it is also advisable to have a spare Aquastat Controller on hand, particularly for GX Series Furnace owners.

Operating a Furnace FAQs:

  • Am I burning too much wood?

You may be. Is the wood properly seasoned? Have you cleared the firebox? High wood consumption can be caused by a number of factors.

  • If I don't use chemicals in the furnace water, what happens?

The water treatment coats the inside of your system and helps to slow down the development of rust and corrosion in your system.

  • Can I leave my furnace over the weekend?

You may have someone "feed" your furnace for you or you may lower the thermostat temperature.

Maintenance FAQs

  • Why is water treatment important?

The chemical (water treatment) coats the inside of the furnace to reduce the effects of corrosion on the metal. Click HERE to order our Liquid Armor Water Treatment.

  • How often do I need to Inspect my Chimney/Flue

Inspect chimney and flue monthly and clean as needed. Clean chimney and flue annually. Perform cleaning and maintenance only when no fire is present in the firebox and ashes are cooled completely.

  • What is the Importance of Catalyst in my GX Series Furnace?

Without or a damaged catalyst in place, the furnace will produce more fine particulate emissions and may run less efficiently.


  • Why am I not getting hot water?

Check that the hot water system is connected properly. Check if the heat exchanger is partially or totally clogged.

  • Why does my furnace continue to burn when it is not operating?

Check the door seal, door adjustment, and solenoid.

  • What are the Common Pex Pipe Problems

Pex has its problems, however, and those should be understood when considering the piping.
