My boiler is about 10 feet from the left door of my two car garage which is also used in winter to make repairs and
for men type loafing.( man cave) . I'm only using two ports on my boiler, one for heating my 5400 sq ft. house and the other heating my domestic water.  My boiler is large enough to heat up to 8000 sq ft. My question is can you install quick coupler on the back of the boiler on one of the ports and run an insulated pipe on top of ground and straight in to my garage  and hooked to a pump on the wall also with a quick coupler.  Run another pipe from the pump to a steam coil  box heater mounted in the ceiling of the garage. That way I could only run pump while using shop in winter and not have to dig up the ground around my garage. Roll up the pipe and store away when not being used ,blow water out of pump and reverse process when I need heat. Sounds complicated I know but would be easy and cheap way to run. I'm open to suggestions on a better way without digging ditch and running heat exchanger.

Almost sounds like more hassle than just digging 10 foot of trench. with no traffic over the trench doesn’t have to be deep at all.

Have shovels and kids? Problem solved.

yep. That's what I was afraid of. Thought just maybe I could do this an easier way.

Would be nice to pop off quick coupler on back of hydronic heater and pump roll up and put away. The same at the back of stove and other side of pump. Only turn the pump on when needed and easily drain system to keep from freezing when your not using. The reverse when you decide to work in the garage for a while.
Also thought about doing same in my swimming pool. It's about 50 ft from back of my stove. Run an insulated pipe on top of ground from pool pump to domestic port on back with same setup as water heater and same kind pipe back to pool jets. When pool gets warm, unhook, roll up pipe and store away. Hook lines back up at pool pump the normal way and your ready to go.

The other thing I see is depending on what your using for insulated pipe, the insulation on it may not take kindly to repeated rolling and unrolling then of course as well your leaving whatever casing it is exposed to the sun when in use.

We buy our drainage tile by the semi load, but never keep stuff around for more than 3 years as the sun will start to make it brittle, but again yours would only be exposed when in use.

Quick couplers also cause a bit of restriction as well so you might need to use a larger pump to force enough water thru em.

I'd just run some closed cell quality pipe below the grass and heat your garage all winter. Don't remember it being that cold down there so I don't expect it would take much to keep the water flowing. Even if you stick a thermostat out there set for 40F....
