10 feet of head is not excessive, however pump there is a difference between for example 1/2″ diameter 3/4″ and 1″ piping size. Its been my observation that most plumbers do not give this sufficient attention. When the system is on grid who cares if the pump works a little harder and draws more current.

That little difference is ccrucial for off grid.

A similar situation exist with electric wiring – especially when wired for DC power instead of AC power from an inverter. wire gauge and resistance is significant

By now it may be difficult to replumb, especially the insulated run from boiler/furnace to house. The Grundfos Alpha may be your best bet.
