What if you already have good insulation? It's already well-known that old houses have shit insulation, so of course it's worth investing money into that if you already need it. But, even heating a new house can be expensive.

If you have good insulation then the weakest link is usually heat lost through ventilation, or an inefficient heating system.

Ground source heat pumps have their place, but it's really a niche. It is possible to cheaply heat a home without them.
