Commercial Hot Water
Heaters
ICA Heating carries the full Patterson-Kelley water heater line — direct-fired condensing, non-condensing, indirect-fired, and the EvoHP electric heat pump. Factory-authorized sales, engineering, installation, and 24/7 service across New Jersey and New York.
The Right Water Heater
for Every Application
Commercial domestic hot water demands are as varied as the facilities they serve — a 300-room hotel has different requirements than a hospital surgical suite or a university dormitory. Patterson-Kelley offers the broadest water heater product line in commercial heating, with models purpose-built for every DHW application.
From the flagship SOLIS W-Series condensing firetube to the EvoHP electric heat pump, P-K water heaters feature premium stainless steel or copper construction, NURO smart controls with remote monitoring, and compact footprints designed to fit through standard doorways and into tight mechanical rooms.
As a factory-authorized dealer, ICA provides complete DHW system engineering — from peak demand analysis and equipment sizing through installation, startup, and decades of preventive maintenance.
An expansion of the flagship SOLIS family into dedicated domestic hot water — the SOLIS W-Series brings firetube condensing technology to high-demand DHW applications. 316L stainless steel construction delivers superior corrosion resistance and long service life in potable water systems.
- Models: SLW1000–SLW3000
- Type: Direct-fired condensing firetube
- Heat Exchanger: 316L stainless steel tube & tube sheet
- Controls: NURO touch-screen with remote monitoring
The HiDRA is Patterson-Kelley's first instantaneous condensing firetube water heater — delivering unlimited hot water on demand without storage tank losses. Ideal for facilities with high peak demand and limited mechanical room space where storage capacity is a constraint.
- Type: Instantaneous condensing firetube — no storage required
- Heat Exchanger: Firetube condensing design
- Advantage: Eliminates standby losses from storage tanks
- Controls: NURO touch-screen with BAS integration
A stainless steel hot water supply boiler purpose-built for domestic hot water applications. The SONIC SCD combines the proven SONIC platform's compact footprint and 316L stainless construction with DHW-specific controls and ASME-rated performance.
- Heat Exchanger: 316L stainless steel
- Design: Compact footprint for tight mechanical rooms
- Application: Dedicated DHW supply boiler
- Controls: NURO touch-screen with remote monitoring
A state-of-the-art vertical design utilizing a radial-fired, fan-assisted burner for efficient DHW production. The sealed combustion system permits installation in negative-pressure environments — the same advantage as its boiler counterpart.
- Burner: Radial-fired, fan-assisted combustion
- Design: Vertical — small footprint, sealed combustion
- Installation: Suitable for negative-pressure mechanical rooms
- Controls: NURO touch-screen controller
Full modulation control combined with forced-draft combustion and scale-resistant construction. The MODU-FIRE FD W Series delivers reliable DHW in hard-water environments where scale buildup is a primary concern for equipment longevity.
- Combustion: Forced-draft with full modulation control
- Construction: Scale-resistant design for hard-water areas
- Heat Exchanger: Copper finned-tube — proven durability
- Controls: NURO touch-screen with BAS integration
Patterson-Kelley's longest-running product line — the COMPACT indirect water heater has been delivering reliable DHW across thousands of installations for decades. Its compact design fits through standard doorways, and replacement bundles keep existing units running for years beyond original expectations.
- Type: Indirect-fired — heated by boiler supply water
- Heritage: P-K's longest-running product line
- Advantage: Fits through standard doorways
- Service: Replacement bundles available for extended life
A fully packaged water-to-water domestic hot water system — the DURATION III pairs a high-efficiency heat exchanger with integrated storage in a single skid-mounted unit. Simplifies installation by eliminating field-assembled piping between separate components.
- Type: Water-to-water with integrated storage
- Design: Fully packaged — single skid-mounted unit
- Advantage: Eliminates field-assembled piping between components
- Application: High-recovery DHW for institutional facilities
A gas-fired condensing boiler and storage tank combined in a single skid-mounted package — designed to produce domestic hot water with minimal to no scale buildup. The MACH 'n' ROLL eliminates the complexity of separate boiler and tank installations.
- Type: Gas-fired condensing boiler + integrated storage
- Design: Single skid-mounted package — boiler and tank
- Advantage: Minimal to no scale buildup in DHW production
- Installation: Turnkey — reduces field labor and coordination
Patterson-Kelley's entry into building electrification — the EvoHP electric heat pump water heater delivers high-efficiency domestic hot water without combustion. By extracting heat from ambient air, the EvoHP achieves COP ratings significantly higher than traditional resistance electric heaters, dramatically reducing energy costs and carbon emissions.
- Type: Air-source electric heat pump
- Combustion: None — fully electric, zero on-site emissions
- Efficiency: COP significantly higher than resistance electric
- Application: Decarbonization, all-electric codes, LEED projects
