Available Fitting Sizes: 1/2" 3/4" (size quantities may be limited)
(State fitting sizes at check-out. If no fitting size is stated, one will be chosen for you. If out of stock, other size will be sent.)
This is a high quality heat exchanger made of stainless steel with a copper brazing. It will not corrode with normal usage and is guaranteed to last for a life-time.
This is an extremely popular unit for wood burning furnaces, radiant floor systems, refrigerant systems, straight vegetable oil conversions, beer chilling and solar water heating systems. It will work for any application in which the desired result is for two fluids (liquid or gas) to exchange heat.
Warranty: You are protected by a life-time warranty against manufacturer's defects with normal usage. (does not include wear and tear as all metals eventually corrode) These units are welded strong and will last a long time without corrosion or break unless fluids with extreme pH levels are used (not considered normal usage if these fluids are used). It is recommended that you clean your unit periodically to preserve its life. Salt water is highly corrosive to any metals and if used, the heat exchanger should be cleaned very often (and still may not be expected to last too long.)

When determining your heat exchanger size and number of plates there are a few things to consider. A long heat exchanger will be most efficient as it allows more time for heat to flow from the hot to the cold. An infinitely long heat exchanger would theoretically take all possible heat from the hot to the cold and they would exit at the same temperature.
The number of plates you have allows a higher capacity of fluid at one time. You would want to have a heat exchanger with many plates if you had a high flow rate and be able to transfer heat effectively. The faster your fluid moves, the less heat is transferred. So if you are pumping a lot of fluid really fast, more plates will allow for more heat transfer.
There are many things to consider when choosing length and # of plates. The greatest reason to have a long heat exchanger is when you are doing only a single pass with your fluid. If you are only doing a single pass, the fluid only gets one chance to heat up. So you should allow it as much time in the heat exchanger as possible to acquire that heat. However, on the other side of things, if you are doing a multi-pass (heating a tank) you could use several plates instead just to handle a higher flow rate.
Time. This is the other key factor to consider when choosing length and # of plates. The smaller your heat exchanger, the longer it takes to heat your fluid. Even when using several passes, it can still take a long time to heat the fluid especially if you are heating large volumes of liquid. Why? Because the heat leaks out of that container as you are heating the fluid in the heat exchanger.
Ultimately, the bigger the heat exchanger the faster your heat transfer is and the less energy you spend on pumping the fluid and the less energy you lose to your surrounding system. When you have plans for long-term usage, the question becomes "Do i pay now, or do I pay later." With paying now being the cost of a large heat exchanger and the later being the energy put into the system to do the job with a smaller heat exchanger.
