I have lived in houses equipped with a forced air furnace plus those with boilers.
There is a immense difference between a heating plan that uses air to transfer heat energy plus 1 that uses water.
A furnace requires a network of ducts that transport the heated air to the multiple rooms plus pull out the stale air. As the air circulates through these pipes, it can choice up any dust, bacteria, mold spores or contaminants that are concealed inside plus spread them into the breathing air. The majority of duct systems have tiny holes, cracks plus imperfections that allow up to 30% of the heated air to escape. The operation of the HVAC duct is constantly quite noisy. When the sizzling air flows out of the vents plus into the room, it naturally rises up toward the ceiling. It only drops down after it has cooled. The process is inefficient plus creates uncomfortable temperature fluctuations. A higher control machine setting is necessary because the highest temperature is near the ceiling. A boiler uses water rather than air to transport heat. There is a closed loop plan that uses the same water over plus over again. It avoids spreading contaminants, makes no noise plus there are no energy losses due to leaks… Rather than getting blown in the room, the heat is infused into the air by way of a radiator, baseboard heating system or radiant floors. There are no drafts, no cold spots plus the temperature everywhere in the room remains within 3 degrees of the control machine setting. Boiler heating is more gentle plus doesn’t dry out the air. It allows for the easy set up of zone control. With a control machine in each room, it’s possible to customize the temperature according to requirements, preference plus occupancy.
