Developers and Providers of:

America’s First Hydronic (Forced Hot Water) HeatingAPPLIANCE!

(Patents Pending – USA & Canada)

Conventional Appearance, with Unconventional Performance!

Boilers On Demand LLC revolutionizes Hydronic (Forced Hot Water) Heating Installations by replacing skilled-technician, built-on-site, piece-by-piece systems with an integrated, performance-optimized APPLIANCE!

Merely position our fully integrated, free-standing, application-specific Appliance and connect to your piping and wiring. Typically a day-cycle install with dramatic material, labor cost and space reductions with guaranteed, superlative performance.

Contemporary installers & methods give no consideration to hydronic distribution and radiation efficiencies. All that superfluous “pretty piping and wiring” actually increases the energy load on a heating system, reducing its performance while taking money out of the consumer’s pocket throughout its operational life ….. knowingly or not!

Fully integrating advanced Taco® Delta-T ECM Hydronics, Weil-McLain® Cast-Iron “High-Mass” Boilers with our proprietary convective steel piping integration methods provide SIMPLE, DURABLE, EFFICIENT FHW HEATING – PERIOD!

NOTE:Total Heating System Efficiency is the AGGREGATE of Boiler AFUE, Distribution AND Radiation Efficiencies!

No guarantee, but our heavy cast-iron/steel/brass/bronze system construction suggests an economic life of 30+ years — twice that or more of any “low-mass” or “on-demand” heating system. In fact our multiple, monitored “beta site” installations have now accrued well over twenty system-years of flawless operation, i.e. no system-related service calls!

SUGGESTION: Check any boiler manufacturer’s water condition warranted demands ….. VERY CAREFULLY! Compare them with Weil-McLain’s UO Series Boiler Warranty and our All Malleable-Cast-Steel Constructed Appliance. No “Magnetite Alleviation” or “Return Water Tempering” requirements with the heavyweight Weil-McLain UO cast-iron boiler – Built to last!

Our Appliance is compatible and interchangeably fired by #2 Fuel Oil, Natural Gas (NG) or Liquid Propane (LP). To change the fuel, change the burner – not the system

DISCLOSURE: Taco Comfort Solutions® provides us with direct engineering technical application support in developing the Delta-T ECM Hydronic Distribution market.

A Hydronic Heating Package, tailored to your application(s), is available directly to both Consumers and Trade Personnel alike. Check our Pricing Schedule herein. Future Dealer Licensing Inquiries are also welcomed.
