I have a small unit located in my ceiling downstairs. I believe It to be a system by the name of Hydronic Heat - My water heater has an inlet and outlet on the side of it to feed the blower / air handler. I'm just having trouble finding any information on the unit. I've typed in the model number with no results. The furnace blower / air handler (I'm not too sure exactly what to call it) is stamped Apollo HydroHeat. Ive called numerous repair companies and with no luck since most wont touch the unit as I'm explaining it as a hydronic system. Its still blowing hot but just today started making a rattling noise and would rather it get fixed before I'm without heat at all. I'm even up for replacing It If I can find out what it is I'm exactly looking for. I can't seem to upload a picture but heres whats on the sticker on the unit itself: Model # : H 2418D 1GS Serial # : G96812617 Fan Motor : 1/3 FLA : 5.00 Thermal Protected MAX Ext. Static : .4 I.W.G. Pump Motor HP : 1/25 FLA. Water Coil: Hot Water Only, Max Temp 160, Max PSI 150. Cooling Ref Coil: R22 Design Pressure: 300 PSI I'm trying to figure out what exactly I'm looking for to replace the unit in the ceiling - My water heater is fine I just installed a Bradford White 2 months ago. I've done a lot of plumbing work so I'm pretty knowledgeable around that area, I will call my HVAC friend over once I buy this new unit, I'm just confused as if this is a furnace / blower / Air handler? I just want to be sure I'm buying the right thing when I do within the next week or so... or if they even make what I need anymore! It kind of scares me 5 HVAC companies I called don't even service this unit and my neighbor replaced hers through a company that is now out of business for 7,000$ which seems very high to me.
