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 Feedwater Economizers for Waste Heat Recovery
A feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming feedwater. Boiler flue gases are often rejected to the stack at temperatures more than 100°F to 150°F higher than the temperature of the generated steam. Generally, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.
