Scope: Replace clogged & leaking 20 yr. old boiler with (2) High Efficiency Boilers for a more flexible system with redundancy in the event of boiler failure.


     The existing boiler at P.F.S. was on its last legs and would only run for a few hours at a time before shutting off. This was a serious problem for the busy busy Ballard shipyard. Containing a full suite of offices, warehouses and workshops the latter of which are constantly exposed to the cold winter air reliable heating is an absolute necessity.


     P.F.S. expected the boiler would make it through one last winter and into the spring as they gathered several bids and weighed their options. However, after one too many mornings arriving to an ice cold workshop enough was enough and they pulled the trigger on a modern and reliable 2 boiler system.

The old gas boiler had seen better days....

60% of the heat exchanger looked like this...Totally plugged

Abundant Heating and Air Conditioning in 5 days, with a one day change-over, had the old boiler out and the heat back on. (With a lot of new floor space as well)


  • (2) NTI TFT-250 95% efficient condensing gas boilers

    • Boilers use outdoor temperature to calculate minimum required water temperature

    • Boilers rotate run time or work in conjunction for peak heating needs on coldest days

  • (3) Grundfos MAGNA 32-100 high efficiency  ECM Circulators- using 70% less electricity than the old heavy pumps with nearly silent operation

  • Caleffi 2" Hydro-Separator providing:

    • temperature sensing

    • air/dirt/hydraulic separation for the entire system, protecting the boilers from the inevitable dirt in the old system piping throughout the building.

Finished Project: A Modern & Efficient Boiler Room

Special thanks to both to Abundant Heating and Pacific Fishermen for being such a pleasure to work with through the entire process
