How to Install a Plate Heat Exchanger on a Hot Water Tank

Plate heat exchangers: how they work Heat is extracted from the wood furnace and distributed throughout the house through a plate heat exchanger. With a truly efficient and renewable resource, wouldn't it be nice if you could heat your home, provide all the hot water you need for your baths, showers, laundry, and heat your pool and spa? How about heating your home while helping the environment? What if it were free?

Plate Heat Exchanger Installation and Assembly We will explain to you why we recommend that you mount the plate heat exchanger on the cold water side.  Thermal pressure syphons are actually quite simple. Basically, the water line will come in, and you're going to cut it, and then you're going to mount it into the plate exchanger, and we always recommend unions. Now you need a lead-free, copper, or brass union. We use lead-free brass here.

A Plate Exchanger: How Does It Work? Water is going to be coming in this way from the domestic hot water side. It will flow in the opposite direction from the wood boiler. By creating a cross flow difference, you will get more heat exchange. Identifying the boiler coming in with the red pipe, it is going to enter through the bottom, rise up the flow, and then return to the boiler or to your next heating system.  Thermal pressure syphon is the reason and how this works. In this case, the water coming out of the boiler is between 170 and 180 degrees. You are heating up water in this plate exchanger, which is coming in at about 55 degrees, give or take a couple degrees depending on your zip code. 

Uses and Applications of Plate Heat Exchangers These exchangers can be used for a wide range of applications, from cooling or heating diesel to exchanging heat between polyurethane and a refrigerant. However, the heat exchangers we have made are specifically designed for wood boilers. In essence, it's a much heavier grade of plate exchanger, which hurts the efficiency a little but has the quality and longevity rather than having to replace it every 4 to 5 years.  Recommendations for the installation of Plate heat exchangers The most important thing is to make sure you're using copper or brass that's lead free on the domestic hot water side. This is water that will now enter your domestic hot water system, so you must use this grade of metal.
