The most common fuel used for boilers in Los Angeles, CA, is natural gas. The fuel type you choose will have a major impact on both your ongoing costs and how much you pay for a new boiler.
Oil boiler: Oil burns hotter than gas, so oil boilers provide more heat and are better in colder climates. However, oil boilers require more maintenance than gas options, so keep things like long-term maintenance costs in mind before buying.
Gas and propane boiler: Propane and natural gas are common options for heating homes. In addition to the unit price, installation costs $1,000 to $3,000 and requires new exhaust lines, drains, and fuel lines.
Electric: Electric boilers are highly efficient and don't require some of the components that gas and oil boilers need, like exhaust vents. They take a long time to heat up but are an attractive option for tiny homes in warm climates.
Wood: Large, outdoor, wood-fueled boilers are good options for rural areas that have easy access to wood.
| Fuel Type | Cost |
|---|---|
| Oil | $1,700–$6,485 |
| Gas/propane | $2,211–$6,485 |
| Electric | $500–$6,485 |
| Wood | $5,000–$9,000 |
Boilers are broken out by fuel type, but they can also vary in other ways—like their system types.
Standard or conventional boilers: These boilers work by quickly heating water in pipes and sending it to your taps. Standard units are one of the most popular choices for homeowners in large homes and those with floor heating systems.
Combination boilers: Combination boilers are popular because they’ll give you access to hot water quickly. However, the supply tends to be limited due to the lack of a storage tank.
System boilers: These work by keeping high-pressure hot water in a sealed cylinder, where it can be sent to multiple taps within your home simultaneously.
High-efficiency boilers: High-efficiency boilers are up to 98% efficient, which accounts for thousands of dollars in savings over the boiler's life. Standard boilers are around 80% efficient, making them ideal for cold climates.
| Type | Cost | Pros | Cons |
|---|---|---|---|
| Standard | $2,211–$6,485 | Good for larger homes | Less energy-efficient |
| Combination | $1,700–$4,110 | Heats quickly | Heats only smaller spaces |
| System | $3,000–$6,000 | Quick, efficient heating | Requires more space |
| High-efficiency | $2,211–$9,000 | Saves energy and money | Higher installation cost |
The capacity of your boiler (in BTUs) depends on your region and climate. Warmer climates make it much easier to heat water, even for larger houses, so fewer BTUs are required. You can estimate your necessary BTUs by finding out which climate zone you live in.
Hiring an HVAC pro for boiler replacement costs $75 to $200 per hour, or about $1,200 to $3,200 total. Don’t attempt to DIY this home improvement project.
