What Makes Marin Different
More Space, More Options
Marin homes typically have larger garages. This makes them perfect for heat pump water heaters, which are ultra-efficient but need good airflow to work. Your Marin garage likely has the perfect amount of space for one.
- Heat pump water heaters need airflow and space — Marin garages deliver both
- Larger utility areas allow for combi-boiler setups that handle heating and hot water
- More room for proper venting and code-compliant installations
Perfect for heat pump water heaters
Harder Water, Consistent Pressure
Water in Marin has more minerals than San Francisco water. This mineral buildup damages boilers and water heaters faster. Unlike SF, water pressure in Marin is generally consistent — you won’t see sudden spikes, but hard water still takes a toll.
- Boilers need annual service to stay efficient
- Water heaters collect sediment quickly
- Fixtures and appliances wear out sooner without care
- Regular flushing is critical to extend equipment life
Protects against rapid scale buildup
Eichler Homes
Marin has many Eichler homes, especially in Lucas Valley. These mid-century modern homes use radiant floor heating. Many still have their original 60-year-old boiler systems, which are now reaching the end of their life. Learn more about our Eichler services →
- Original copper pipes in the slab may still be functional but need pressure testing
- Modern high-efficiency boilers require clean systems — old sludge must be flushed out first
- Radiant floor heating is embedded in the concrete — repairs require specialized knowledge
- We have replaced dozens of Eichler systems across Lucas Valley and San Rafael
Specialists in 60-year-old boiler systems
Eichler Homes in Lucas Valley & Marin
Designed by architect Joseph Eichler, these homes were built on concrete slabs with copper pipes embedded in the floor for heating. They were revolutionary for their time. Today, those original systems are over 60 years old. When an Eichler boiler fails, we don’t just swap it out. We follow a strict process to protect your new investment. Old boilers were built like tractors — they could run through anything. Modern high-efficiency boilers are like high-performance cars. They are more efficient but need clean systems. If we connect a new boiler to dirty pipes, it will fail quickly. We make sure your system is ready.
- Pressure test the pipes to check for leaks in the floor
- Flush the entire system to remove decades of sludge
- Ensure lines are completely clean before connection
- Install a new high-efficiency boiler (95% efficiency vs the old 50%)

Tips for Marin Homeowners
Practical advice from 20+ years working in Marin homes.
Consider Heat Pumps
If you are replacing a water heater, look into a heat pump. They are 400% efficient and work well in garages with plenty of space and airflow.
Annual Maintenance is Key
The water in Marin is harder than in other areas. This causes mineral buildup in boilers and water heaters. Regular maintenance prevents damage and keeps your warranty valid.
Advice for Eichler Owners
If your original boiler is still running, that’s great. But when it fails, you need a specialist. We know how to flush and prep these 60-year-old systems so your new boiler lasts. See our Eichler services →

Common Novato & Marin Questions
Why do boilers fail so often in Marin?
It’s usually the hard water. Minerals build up on the heat exchanger, causing it to overheat and crack (“kettling”). Regular annual flushing with a descaling solution is the only way to prevent this. If you skip maintenance, the boiler will fail prematurely.
Can I put hardwood floors over radiant heating?
Yes, but you have to be careful. Engineered hardwood is best because it’s more stable. Solid hardwood can shrink and gap from the heat. We work with your flooring contractor to ensure the surface temperature stays within the manufacturer’s warranty limits.
Do I need a permit for a water heater in Novato?
Yes, permits are required by the City of Novato and Marin County. This ensures safety compliance, including seismic strapping and proper venting. We pull the permit and schedule the inspection as part of our installation package.
My Eichler has original pipes. Are they safe?
The original steel or copper pipes in Eichler slabs are surprisingly durable, but they don’t last forever. Before connecting a new boiler, we perform a pressure test to ensure there are no leaks under the slab. If leaks are found, we can often abandon the bad loop or repair it without tearing up the whole floor. Learn about our Eichler process →
