Give the oil burner away on craigslist and heat water for heat and domestic use with the other unit?

S-F's got the right idea. I thought about that, but its just too simple. LOL And I'm not sure even two Sayno's would be able to provide all the heat esp when you need it most, when its cooold.

That old HS Tarm is my main backup heat. If we get some global cooling,
it's going to come in very handy.. The nice thing about the HS Tarm, the
water jacket is made out of repairable steel.. Theoretically, it could last
another 20 to 50 years.

Any chance you could hook the HX from the hacked HP to water return on the Boiler? and set it to run at a lower temp so it would only fire if the HP couldn't keep the circulating water up to temp?

I rec'd a quote last week for $9300 for a 30K BTU Mitsu unit, and after reading this thread, I just don't see any way to justify those numbers. Sooo, I've just put in an order for a Fujitsu 24RLXFW. Honestly, I'm a little terrified right now. I've never done any electrical or HVAC work. I hope you don't mind if I pick your brain once I get a little deeper into this. Thanks for writing your experiences! I'm not sure yet, but I think you've saved me thousands of $.

Default Nice choice.

Ah ha! "Heating Range (BTU/h) 7,500-36,200"!
I'll bet that will work right down to about 5deg F too. Should be pretty good for NJ weather!

I think you might want to check out some of the newer install videos on youtube.

The Fujitsu 24RLXFW seems like a terrific unit. And the price (Under $2,300) is dang good.

Start up a thread and post a URL to the manual, so you can refer to page
numbers when asking those DIY questions.

I think we might have 4 or 5 Mini-split DYI installers here, so you should
get some good input.


If you read the manual and decide it's just too much to deal with,
maybe you could look around for more estimates.
I'll bet an estimates could be lower, if you already had a pad installed
and the 230v service was ready to go.
Unless, you have to snake 80 feet of line-set all over the place..

Cheers,
Rich

You had me do a double take. Heating is "only 27K". :P But yeah, should be good for any temp we see here. It's only 600 sq ft with 11 ft ceilings, but with garage doors being so leaky, I upsized a bit. I hope it'll work out.

Actually, it's going in my garage, and the outside unit will go just behind the wall and down 8 feet (will be wall mounted to avoid issues with snow accum against the back of the garage). I'll spend 5 minutes snaking my line set and probably another 2 hours gently coiling up the excess. Electric panel is right in the garage too. Funny thing is, the first installer was a no show, second never bothered to give me the quote (seemed more interested in selling a radiant heat system), and this was the 3rd quote. I had another guy scheduled to come out next week, but at this point my mind is made up...DIY.

Unit will go above that trash can about a foot down from the ceiling. Electric panel is on the left and outside unit will go somewhere along that back right behind the inside unit.

*sigh* Must have 5 or more posts to link pictures! Pics removed.

I'd say that you have ordered a spectacular garage heater.

How much time do you spend in the garage?

How do you heat the rest of the house?

Not that much time spent in the garage. I do work on the cars from time to time, and I've always wanted a proper workspace (which includes conditioned air). As a side benefit, my dog gets to enjoy it when the weather doesn't cooperate. It doubles as his playroom. This winter it also gives me a place to miter replacement moldings that fell victim to him (one yr old Golden that passes time chewing molding at my expense).

Rest of the house is central air and natural gas furnace for heat.
