Frequently Asked Questions

Do I need recirculation with a tankless water heater in a large Tiburon home?

Larger homes would do well with a recirculation pump, since this will prevent longer wait times in appliances that are further from the unit.

Can I install a tankless water heater outside in Tiburon?

Absolutely! As long as the specific brand of tankless unit is designed to withstand the outdoors, it can certainly be installed on the outside of your house.

Can one tankless water heater handle a large home with multiple bathrooms?

As long as the unit is properly sized by a professional, it can absolutely handle a larger home with multiple bathrooms.

What are the disadvantages of tankless water heaters?

There can be hefty installation costs and upgrade requirements. It also may not be able to efficiently heat your appliances if you use many different hot water utilities at once.

What happens if I don’t flush my tankless water heater?

This can lead to heavy mineral buildup in the unit that can reduce system performance, raise your energy bills, and even cause damage to the unit.

Why is my tankless water heater taking longer to provide hot water?

Tankless units heat water as it comes into your house rather than storing it all in a tank. This means it will take a bit longer for the water to become hot; typically 2-3 minutes.

Why is my tankless water heater making unusual noises?

Unusual sounds like popping or rumbling can be a sign of mineral buildup in the unit. It is a good idea to flush the system and call a plumber if the noises persist.

Can an older Tiburon home support a tankless water heater?

Yes, but there may be steep home upgrades needed in order for a tankless system to work efficiently in an older structure.

Do I need a larger gas line for a tankless water heater?

Yes. Tankless water heaters use a significantly larger amount of fuel than tank water heaters and therefore require a bigger gas line.
