Wood Central Heating
With Thermal Water Storage

The Ultimate Wood Heat System

• Highest possible efficiency and lowest emissions--without compare.

• Saves time and wood--you load the boiler less often.

• Extends the burning season, even burn year-round--efficiently.

• Assures the longest possible boiler life--good for the boiler.

Why Do I Need Heat Storage?

Cozy Heat, and all European designed, true high efficiency, gasification boiler manufactures recommend that the best installation of boilers is one that includes a heat storage tank. By storing boiler heat in an insulated water storage tank you gain increased operating flexibility and you can easily extend the wood-heating season.

When the boiler is operating, it is producing heat at full output with the cleanest and most efficient operation. The heat output is usually greater than the heating requirements of the house. This "extra" heat is transferred to the storage tank use later, after the boiler has completed a burn cycle. Because of the buffer the heat storage system provides, you are free to fire the boiler when it is convenient for you. Typically only once during a 24 hour period. In summer you will be able to go 4-10 days between firings to heat all of your domestic hot water. There are no problems with creosote or overheating if the boiler is oversized.

Cozy Heat offers a collapsible urethane foam tank with EPDM rubber liner and attractive embossed aluminum outer skin. These tanks range in size from 415 to 1550 gallons. They are shipped in a 19" wide crate and can easily be moved through narrow doors or down stairs. The 48" tank height allows the use of fully immersed vertical heat exchangers, which takes full advantage of the heat stratification in the tank. It is unique and has the capability to be used for space heating, heating domestic water, and solar heat storage.

Some boilers, especially outdoor stoves, advertise large quantities of water. This doesn't help. You need your water storage separate from your boiler and let the controls decide where the heat comes from. You're boiler will provide heat for your home but also provide heat for thermal storage, then when the house is satisfied all the boiler heat will go to the storage system. When the boiler has depleted the wood supply it will shut down, holding the last of the coal bed for firing later, and your home will continue to draw from the thermal storage for many hours or days.

Tanks purchased from Cozy Heat are expensive but the guess work is gone. Many people get very creative from underground tanks, propane tanks, cement, steel, etc. You need to follow some guidelines. A great resource if you're a do-it-yourselfer is to go to www.hearth.com and spend some time chatting with others who have had much success and failure; no point re-inventing the wheel.

We, at Cozy Heat, are here to help you design and build the ultimate heating system. You can do this as simple as you like or high-tech if you perfer. It will cost a few extra dollars but it will be an investment that will last for many decades using as little fuel as humanly possible to comfortably heat your home.
