Should I repair my boiler or get a new one?
If your boiler is less than 8 years old repairing, it makes sense (pending the leak is only small). If your boiler is 10 plus years old, and you are regularly topping up its pressures you could consider replacing the boiler.
What does a boiler do in HVAC?
Boilers heat water, which provides either hot water or steam for heating.
Steam is distributed through pipes to steam radiators and hot water can be distributed through baseboard radiators or radiant floor systems.
Are boilers energy efficient?
The boiler will use less fuel to provide more heat. This means your cost of energy will be lower in the long run. The boiler does not require a blower to circulate heat through the home which means the level of noise is reduced.
