Yes, a heat exchanger can be replaced on a Laars Lite 2 LD400P. However, it is important to ensure that you obtain the correct replacement part and follow the manufacturer's guidelines for installation. If you're not experienced with boiler maintenance, it’s advisable to hire a qualified technician to perform the replacement to ensure safety and proper functioning.
If the leak is in the copper fins/heat exchanger : replace the exchanger, gaskets etc Not a job for someone who is not familiar with pool heater construction and service. If the leak is at the inlet or outlet you may have to remove those fittings and replace woth new ones.
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.

The duty of a heat exchanger can be defined in an easy way as "The amount of heat exchanged from a fluid at a higher temperature to the fluid at lower temperature in unit time by a heat exchanger is called its duty"

It is necessary to schedule a heat exchanger replacement when the current heat exchanger is damaged, malfunctioning, or no longer efficient in transferring heat effectively. Regular maintenance and inspections can help determine when a replacement is needed.
The efficiency of a heat exchanger is directly proportional to its surface area. This means that a larger surface area allows for more heat transfer, resulting in a more efficient heat exchanger.
The noise is coming from the heat exchanger located just above the burner tray. One or more of the heat exchanger tubes has become blocked or reduced in size from calcium buildup - - - improper adjustment of your pool's pH which can happen is a short period of time. The knocking is caused by steam or the lack of proper water flow through the exchanger tubes. Someone, and I am not mentioning names has not done their job of maintaining the pool properly. If left alone the exchanger will fail and you will have a great expense of replacing the heater. Another possibility is that the heater by-pass valve is failing. You need a qualified pool tech to advise. He can only assess the problem through a heater visual inspection --- that means disassembling the heater to look at the exchanger tubes. Sorry for your misfortune. k

A heat exchanger is a device that transfers heat from one fluid to the others. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. Majorly condenser is used to cool the required vapor and heat exchanger is used to heat the required liquid.
When was the last time the filter was cleaned? Have all the components in the heater system been checked for proper values? Does the heater sound as if it wants to fire up? Does it have a pilot light or electronic ignition? Have the orifices been checked for bugs or spiders? Ken
Yes, you can replace the heat exchanger in the unit, but will cost approximately 1/2 of the price of installing a brand new unit. The exchanger should only be replaced if the unit is less than 6-7 years old and in excellent shape, especially the combustion chamber lining. Matt - Flamborough Gas and Oil.
