The Ups And Downs Of Bleeding Home Radiators For Efficiency

Many people like to occasionally "bleed" their home's radiators to improve their energy efficiency. While this is a good practice if done properly, it can unfortunately cause problems that can damage a home's boiler. It may even make repairs or boiler replacement necessary.

Opening Radiators Can Help With Energy Efficiency

Bleeding a radiator is as simple as locating the radiator key, turning off the heat, inserting the key, and turning it slightly to release a little air. The exact amount will vary depending on the radiator. A good pressure gauge should help dictate how much air needs to be released to keep it safe from damage. Radiators need to be balanced with the air pressure contained within the coils.

Bleeding them like this helps improve efficiency by releasing the excessive air and avoiding heating it unnecessarily. Unfortunately, it can be a problematic procedure when it isn't performed properly. Bleeding too much air can end up affecting the air pressure of a home's boiler.

However, It Can Lead To Low Boiler Pressure

Every time a homeowner releases pressure from their radiators, they are removing some from their boiler. Releasing a small amount at a time shouldn't be a major problem here. However, releasing a large burst of air from a radiator can cause the pressure in the boiler to drop significantly. The problem here is the way it can affect the boiler operation in the rest of the home.

Too little pressure can make it nearly impossible for the boiler to pump heat and water through a home properly. It can lead to poor heating conditions and uncomfortable living conditions. Dealing with this problem can be difficult, particularly if low air pressure leads to boiler damage.

The Cost Of Repairs

Low air pressure in a boiler can cause damage by forcing it to work too hard. This is particularly true if homeowners don't manage the low pressure immediately and let the damage compile. Repairing a boiler can be somewhat expensive. For example, the national average for repairing boiler damage is currently about $175-600. In most cases, it should handle boiler damage.

However, serious enough damage may make it necessary to get a new boiler installed in a home. This can be a pricey proposition for many homeowners, as estimates of several thousands of dollars are typical for boiler replacement.

As a result, it is better to address minor problems and slight damage before they become a more serious problem. Thankfully, this should be fairly inexpensive for most homeowners to cover, helping to save them a lot of money in the process. Contact a company like Boiler Services, Inc. for more information.
