Boiler Plate Heat Exchanger (DHW) Replacement in Greater Vancouver
Produces instant domestic hot water in combi boilers. Supplied and professionally installed by licensed gas fitters — never sold for DIY.
What the Plate Heat Exchanger (DHW) Does
The plate heat exchanger is the small brazed-plate unit in a combi boiler that transfers heat from the primary heating circuit to your domestic hot water on demand. Scale build-up is the number-one cause of "lukewarm hot water" complaints on combi boilers in hard-water and mineral-rich areas.
When you open a hot tap, the diverter valve sends hot primary water through one side of the plate exchanger while cold mains water flows through the other side, heating it instantly for taps and showers.
We supply and fit the plate heat exchanger (dhw) as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
