Success Story
Heat Exchanger Helps Langley Memorial Hospital Keep the Domestic Hot Water Flowing
Langley Memorial Hospital is a government-funded acute care facility in the Township of Langley British Columbia that is owned and operated by Fraser Health Authority.
Mark Gushulak, Chief Engineer at Langley Memorial Hospital had a Hot Water Tank that had been operating successfully since the mid 1960’s providing years of trouble free service. Inspection revealed cracks starting in the shell and a project was initiated to replace the tank. A call was made to Andrew Reynolds to supply an Instantaneous Domestic Hot Water Heater capable of handling the same flow. A turn-key quote was provided that involved removal of the old tank, reconstruction of the tank mezzanine level and installation and commissioning of the new hot water heater. Included in the design was a steam powered condensate pump that returns the condensate back to the boiler.
This successful solution has been in operation for many years now and is once again providing Langley Memorial Hospital trouble free domestic hot water service. Mark Gushulak reports we are very pleased with the installation and there may be an opportunity in the future for another instantaneous domestic hot water heater.

Use a Vent Condenser to Recover Flash Steam Energy
When the pressure of saturated condensate is reduced, a portion of the liquid “flashes” to low-pressure steam. Depending on the pressures involved, the flash steam contains approximately 10% to 40% of the energy content of the original condensate. In most cases, including condensate receivers and deaerators, the flashing steam is vented and its energy content lost. However, a heat exchanger can be placed in the vent to recover this energy.
