MBH input, 600 MBH output. The steam <br /> piping will be disconnected, the boiler will be installed adjacent to the air <br /> handler, and the boiler will be connected to the existing coil in the air handler. <br /> The first boiler will be controlled by an indoor-outdoor thermostat, with the <br /> second boiler controlled by an outdoor thermostat. The boiler will include <br /> electronic ignition, vent dampers, and a duplex pump package to circulate the <br /> hot water thru the coil. <br /> Total Price for this System: $16,550.00 . <br /> In the existing boiler room, we-propose to furnish and install a five module boiler <br /> unit, with a total of 1,875,000 BTUH input and 1,500,000 BTUH output. Included <br /> in this part of the project will be necessary gas piping, temperature control, <br /> connection to existing piping, and modifications to existing radiation as required <br /> to convert from steam to hot water. This boiler will have five (5) steps of con- <br /> trol and will 6e very energy efficient:._ <br /> Total: $27,550.00 <br /> Alternate #1 - To remove existing boilers. Add: $6,877.00 <br /> Notes: <br /> l. - All work to be performed on regular tune. <br /> 2. We assume that the existing steam piping is adequately sized for the supply <br /> and return hot water piping. This must be verified'.by a registered engineer: <br /> We include the cost of this study in our proposal, but we do not include the <br /> cost to .change supply or return piping. <br /> 3. Necessary permits are included in our proposal.. <br /> Sincerely, <br /> NORTHERN PLUMBING & HEATING, INC. ' <br /> James L. Busscher <br />
