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.

Consider Installing a Condensing Economizer
Boilers equipped with condensing economizers can have an overall efficiency that exceeds 90%. A condensing economizer can increase overall heat recovery and steam system efficiency by up to 10% by reducing the flue gas temperature below its dew point and improves the effectiveness of waste heat recovery and fall under 2 categories. An indirect contact condensing economizer removes heat from hot flue gases by passing them through one or more shell-and-tube or tubular heat exchangers. A direct contact condensing economizer consists of a vapor-conditioning chamber followed by a countercurrent spray chamber. In the spray chamber, the cool liquid come into direct contact with the hot flue gas, providing a non-fouling heat transfer surface
