Heating something with chemical energy by combustion (for example) has a large second law loss -- there's a large increase in entropy in combustion, and in transmitting the high grade heat to the low temperature of the building being heated. Because of these avoidable entropy sources, it's possible to be smarter, for example to use a gas-fired heat pump to achieve a COP of > 1.

Yeah, a simple absorbtion refrigerator (gas fired) is already way better than a gas oven.
The plumbing is just more expensive than works often be worth it, and the nice low-temperature systems run on what's essentially an ammonia destiller.
