This is a pretty substantial move if for just aesthetic purposes, unless you are remodeling to gain a new bedroom or den or such. You did not say anything about hot water heater - usually the two sit side by side to keep all the piping and waste heat sources and potential leak sources together.

Assuming the move does not bring up any other issues for some reason, probably about $150-250 to move the power outlet (generally under code the power switch cannot be more than 6-10 feet from the unit and has to be clearly visible from it) unless you have easy access to tap into power at the new location - though in some code areas boiler/furnace has to be on its own breaker so moving the outlet is more likely in that case. Good idea to be on its own breaker so something else tripping the circuit out does not cause loss of heat. This does NOT include drywall repair and repainting cost, which you might be able to DIY, or might cost several hundred $ more unless your area and room appearance standards allows a surface conduit run for the move, which would be a bit more than $ above but significantly cheaper than tearing into walls to move the wiring and then fixing/repainting the walls.

Plumbing cost for the move and pipe reconnections - cold water plus the hydronic or steam heating loop pipes, and extending the thermostat wiring to the new location, and if in a garage moving the platform or perhaps building new one, probably on the order of $1000-1500. Sometimes easy to relocate the "manifold" or "christmas tree" pretty much intact with the boiler, then just tie the loops and cold water pipes back into it, so in best case might get for a bit less than $1000. Other times, especially if this is a combined domestic hot water and heating system using a larger storage tank and metering between the two systems so a lot more plumbing plus boiler plus tank to move, can be almost as much work as putting in a new system - which is commonly $1500-2000 labor range.

One consideration - likely need for substantial insulation on the hot (outflow) pipes at least so you don't lose too much heat before it gets to the loops, because this 25' move (unless it happens to shorten the run to the loops) will be a substantial radiator in itself. May also have to insulate the return lines, because with an additional 50 feet (feed and return) for each loop those will act as one giant heater for that room. Might need an additional few hundred $ to build a soffit box at top of wall for the pipes, with easily removeable front and bottom to repair any leaks, fully insulated to keep the excess heat from that room.

I assumed above that the pipes could be run along the top of the wall or ceiling or in exposed floor joists to the new location from the old location - if you want the pipes unseen except right at the boiler, probably another $500-1000 range for the plumbing and drywall/painting to repair the drywall damage from getting the pipes into the wall or much more likely, overhead ceiling.

Also, if that new location does not have a floor drain nearby for any blowdown or leakage from the boiler, you are looking at typically (assuming on concrete slab) $500-1000 more to run a new floor drain into that location.
