Outdoor wood boiler heat exchanger

What is an outdoor wood boiler heat exchanger? Well, an outdoor wood boiler heat exchangers is a brazed plate heat exchanger - a stacked plate heat exchanger that transfers heat or cold between two mediums, f.e. water to water, water and glycol mix. This type of brazed plate heat exchanger is used to separate two system fluids from each other and make the most efficient way to transfer heat or cold. This brazed plate heat exchanger allows you to keep one system pressurized and leave the other non-pressurized. The hot water from your heat source, such as boiler or furnace, enters one side of the brazed plate heat exchanger and the cold water you need to heat enters the other side of the brazed plate heat exchanger. The waters or fluids flow in different directions in separate channels without mixing. This flow of water through the brazed plate heat exchanger makes the best heat transfer possible. The brazed plate heat exchanger is made from 316L stainless steel, 316 low carbon steel for the longest life possible. It can withstand chemicals as well. The brazed plate heat exchanger is made for potable water as well as glycol mix. You can feel safe that you are buying a quality product.

Who needs an outdoor wood boiler heat exchanger? Well, anyone who wants to transfer heat from outdoor wood boiler or outdoor wood furnace to a domestic hot water system or to a radiant floor heating system or to a driveway snow melting system.


Brazed plate heat exchangers can be used for swimming pools as well. Use of chlorine and other chemicals should be under controlled environment. For a swimming pool, we recommend brazed plate heat exchangers made of marine grade stainless steel. They can withstand corrosive environment, such as use of pool chemicals for a long period.

Using a brazed plate heat exchanger for in-floor heating and driveway snow melting is ideal as you can use anti-freeze or glycol-mix. That will give you piece of mind and save your expensive in-floor heating system from a disaster.

Brazed plate heat exchangers come in various sizes and with different fitting connections as well. It is important to size correctly the heat exchanger for your specific application. Make sure you get at least 1-1/4” mpt connections for any outdoor wood boiler heat exchanger that has 50 plates or more. That way you do not get an excessive pressure drop and your heating system will work well for a long time.
