Does anyone have advice for an old boiler system with fin radiators.

We are freezing in here!

The inspector said it needs to be replaced.

What is the most cost effective option?

HELP and thanks!!

Get a Mini Split Heat Pump Systems! 

Boiler
A boiler takes oil, natural gas, electricity, or alternative fuel and turns it into hot water or steam. The hot water/steam is then circulated using radiators or radiant floor systems.

Cons:

The heating and cooling systems are distributed separately. You'll need radiators for heating AND ductwork for cooling.

Initial cost is very high compared to other heat sources.

Slower to react to thermostat commands.

Possibility of frozen pipes if the house gets too cold.

Leaks can cause floods and significant damage to your home.

If you don't want to rely on Passive Design to cool your space, you'll need an Air Conditioning system too.

Heat Pump:

A heat pump pulls heat from air, water, or the ground and transfers it into or out of your home by way of air (more similar to a furnace than a boiler). These systems are called air-to-air, water source, or geothermal heat pumps.

During cold months, the pump pulls heat from outside and pushes it inside. During warm months, the pump pulls heat from inside and pushes it outside. For this reason, heat pumps work best in moderate climates.

Pros
It collects rather than produces heat making it MUCH more efficient that other systems.

No need for Air Conditioning. Heat pumps can heat AND cool. They're also amazing dehumidifiers.

Many new heat pumps have a desuperheater (<hilarious word) which recovers waste heat and uses it to heat water. Desuperheaters are significantly more efficient than traditional water heaters.

Cons
Air source heat pumps require an outdoor compressor/condensor and an indoor air-handling unit.

Can have problems with low airflow, leaky ducts, and incorrect refrigerant charge.

Why did he say it needed to be replaced? It could be just air in the line that needs to be bleed. Boiler looks fairly new.
