About this file
This document provides details on a federal contract opportunity to replace domestic hot water heaters at a Veterans Affairs medical center. The solicitation seeks replacement of combustion-type liquid propane or natural gas-fired domestic hot water heaters with an instantaneous steam-to-water heating system. The system described uses a high-efficiency plate and frame heat exchanger to produce hot water from low-pressure steam on demand, eliminating the need for large hot water storage tanks. This provides benefits such as reduced floor space needs, lower risks of stagnation and Legionella growth, and decreased heat loss compared to traditional hot water tank systems. The solicitation also includes requirements for control panels, valves, condensate removal options, and other auxiliary equipment to provide a turnkey steam-to-water heating solution. Interested vendors must submit responses by the deadline given in solicitation number 36C24821Q1311 issued by the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 8.

Heat MiserInstantaneous Steam to Water Heater
The Heat Miser is an Instantaneous Steam to Water Heater which produces hot water from steam.
The Watson McDaniel fully-assembled Heat Miser eliminates the need for large hot water storage tanks and saves significant energy which is required for large standing tanks of hot water.
Common Applications: Hospitals, Schools & Universities, Hotels, Process Washdown Stations, Residential Apartment Buildings or any other facility with an existing steam boiler.
System Benefits
• Meets the rigorous demands of domestic water heating
• Accommodates extreme load fluctuations without the need or storage tanks
• Accurate control of outlet water temperature for many systems to +/- 2ºF, and +/- 8ºF for wide and sudden load fluctuations
• High-efficiency Plate & Frame Heat Exchanger optimized for use with low pressure steam and offers typical flow rates up to 300 GPM, with higher flow rate designs available
• Integral Control Panel included for ease of operation and system feedback
• Electric and Pneumatic Control Valves available for precise steam control
• Excellent for washdown stations
The Watson McDaniel Difference
• ASME qualified welders and certifications
• ASME U and UM Stamp availability on appropriate components
• Complete assembly and pressure testing prior to shipment
• Better control of design, cost and quality by avoiding 3rd party fabricators
• Unparalleled turn-around and deliveries with many units available for shipment within days
Standard Auxiliary Items
• Steam and Condensate Inlet Y-Strainers
• Stainless Steel Recirculation Pump
• Over-temperature Protection – Solenoid-actuated Cold Water Injection
• Steam Inlet Pressure Gauge
• Stainless Steel RTD Electronic Temperature Sensor
• Stainless Steel Waterside Piping with Safety Valve
Old Hot Water System Negatives
• Takes up excessive floor space
• Stagnating hot water
• Danger of Legionella Growth
• Corrosion of tanks
• Significant radiant heat loss
New Heat Miser System
• Small footprint (typical floor space of 14ft2)
• Efficient plate & frame heat exchanger maximizes turbulent flow for instantaneous hot water on demand
• Stainless Steel waterside components
• Simple maintenance and reduced overall costs www.watsonmcdaniel.com •• Pottstown PA • USA • Tel: 610-495-5131
