Radiant Heated Floor Installation in San Rafael — FAQ

How much does heated flooring cost to operate?+

Electric radiant floor heating costs about $0.15–$0.25 per square foot per month in NorCal. A typical 80 sq ft bathroom adds $12–$20/month to your electric bill when used daily.

Can heated floors go under LVP?+

Yes, but use a system rated for floating floors and keep the temperature below 85 degrees F. Not all LVP brands are compatible — check the manufacturer's specifications.

Do heated floors replace a furnace?+

In NorCal's mild climate, heated floors can supplement your heating system but typically do not replace it. They are best used as spot heating in bathrooms and kitchens.

How long do heated floor systems last?+

Quality electric radiant heating systems last 25–30 years. The heating element is embedded in the floor, so it is essentially maintenance-free once installed.
