Benefits that make it last. ..
•
Maximum Heat Exchanger Performance
- Durable cast Iron primary heat exchanger extends product life - it is
not uncommon for cast iron boilers to last in excess of 40 years.
-
Corrosion resistant stainless steel condensing secondary heat exchanger, Increases efficiency
up to 5% by recouping heat energy from exhaust normally wasted when vented from the building.
•
Reliable Boiler Design
-Unlike most high efficiency boilers in the industr)( the WM GV90+ has extra-wide waterways
(over
2")
allowing sludge and debris, often present in older systems, to flow through easily. This limits
scale build up, which reduces boiler efficiency, performance and can lead to premature boiler failure.
-Down-fired, counterflow boiler design
improves
boiler efficiency The GV90+ offers (5) pass design in
the primary heat exchanger and
(2)
pass design in the secondary heat exchanger maximizing heat
transfer and optimizing boiler efficiency.
•
Smart Circulator Strategy
-Built-in dual circulator strategy provides boiler protection- it can accept low return water temperatures
(down to 60° F) with no additional mixing valves, pumps, wiring and installation labor- a savings of over $500.
-The lower
water temperature also allows
homeowners
the flexibility to add radiant heating for kitchens,
baths or other living spaces without the added cost of special return temperature controls.
•
Proven Control Strategy
-The control platform features error-proof, labeled, snap
in
connections. Tested at over 100,000 cycles,
and boasting a failure rate of
less
than 1% over 20 years, it is sure to provide years of worry-free operation.
- Unlike traditional cast iron boilers, the GV90+ offers a unique control design allowing easy integration of
outdoor reset to take advantage of low water temperatures and improve overall system energy cost savings.
