trying to decide which horizontal hot water unit to go with. I'm coming off my oil boiler with one of these units. it's a straight shot from the boiler through the wall to my garage
(maybe10 to 12' away). unit is a modine either HC 47,000 btu or a HC 63,000 btu unit. I understand the btu #'s are going in & actually comes out to 21,100 or 37,900 coming out
(hope this makes sense & that's with 200* water). I live in NY area(hudson valley) so we do have some nasty winters. I've never seen the garage go below 34* & that was when it was
9* below(last week in fact). it's a two car garage. I have two insulated garage doors, one front wall insulated on the basement side, one wall half concrete & half insulated with a window and one wall all concrete with 75% of it back filled with dirt in front of house. ceiling is 9' high insulated & closed in with sheet-rock. the square footage is 720 sq.'. most the time with temps outside in 30- 35* range the garage is around 42 ish*. my goal is to be able to work in the garage with a shirt on. I'm not looking to maintain a steady 65* temp but want it to be 65* while I'm in the garage. I just want to turn the heat on wait till the garage heats up & go downstairs(maybe a 1/2 hr. warm up time). when I'm done I'll turn heat off. the boiler is plenty big enough so that's not an issue. I heat house with wood stove so boiler has light duty unless it's below 20*. the units I'm looking at are
Modine HC - 47,000 BTU - Hot Water/Steam Unit Heater or
Modine HC - 63,000 BTU - Hot Water/Steam Unit Heater.
my installer has some free time & I'm looking to pull the plug tomorrow. any help would be appreciated. I'm just concerned that the 63,000 unit is to much. causing it to fast cycle on & off.
thank you, Carlo
ps. have a neighbor with the 63,000 btu unit & a 4 car garage under house & it seems to be plenty big enough for His garage. but when I talk to the supply places they want me to go with the same unit 63,000.
