What is Water Heater – Boulder County, CO?
The Water Heater form is a template published by Boulder County Licensing for recording the details of a water heater: one table for a standard tank type heater and another for an instantaneous/tankless system.
The page opens with one instruction: complete one or both of the tables, depending on your water heater type.
- Standard Tank Type Heater: columns for Make and Model #, plus a rating column. Provide the BTU rating for a gas water heater or the kW rating for an electric one.
- Instantaneous/Tankless Systems: columns for Make and Model #, Flow Rate (GPM) at an 80°F or 100°F rise, and Storage Tank Capacity (Gallons), if applicable. The form tells you to indicate which required degree rise is used in the flow rate column.
The form asks only for equipment data. It has no owner, parcel or tax fields, so it is not a property tax document. It prints no form number, revision date or deadline, and it does not say which application it accompanies. Boulder County's restaurant and food vendor licensing page describes Plan Review as the approval process before construction, an extensive remodel or obtaining a retail food license, but the water heater form does not state that it belongs to that process or to any other.
Who needs to file Water Heater – Boulder County, CO?
Anyone who has to describe a water heater to Boulder County Licensing on this template completes the table that matches the equipment. The form sets the rule itself: complete one or both tables, depending on your water heater type.
- Standard tank type heater: complete the first table with the make, the model number and the rating. Give the BTU rating if the heater is gas and the kW rating if it is electric.
- Instantaneous/tankless system: complete the second table with the make, the model number, the flow rate in gallons per minute (GPM) and, if the system has a storage tank, its capacity in gallons.
- Both types on the same project: complete both tables, one row per unit.
The form does not say who is required to submit it, who may sign for someone else or which businesses or projects it applies to, and it has no signature block. Check with Boulder County Licensing whether the form is requested for your application.
How to fill out Water Heater – Boulder County, CO
Choose the table for your heater
Read the opening instruction: complete one or both tables depending on your water heater type. Use Standard Tank Type Heater for a tank unit and Instantaneous/Tankless Systems for a tankless one.
Enter the tank heater make
In the Standard Tank Type Heater table, type the manufacturer's name in the Make column.
Enter the tank heater model number
In the Model # column, type the model number exactly as it appears on the unit.
Enter the BTU or kW rating
Provide the BTU rating if the water heater is gas, or the kW rating if it is electric.
Enter the tankless make and model
In the Instantaneous/Tankless Systems table, fill in Make and Model # for each tankless unit.
Enter the flow rate and rise
In the Flow Rate (GPM) column, enter the gallons per minute and indicate whether the 80°F or 100°F rise is the one used.
Enter storage tank capacity if applicable
If the tankless system has a storage tank, enter its capacity in gallons in the Storage Tank Capacity column. Otherwise leave it as the form allows.
Review and download the completed PDF
Check that each table matches the equipment type, that ratings use the right unit and that the degree rise is marked. Download or print the completed PDF from FillingPDF.
Common mistakes to avoid
- Completing only one table when your project has both a standard tank heater and a tankless system; the form says to complete one or both tables depending on type.
- Filling in the Standard Tank Type Heater table for a tankless unit, or the tankless table for a tank heater, instead of the table that matches the equipment.
- Giving a kW rating for a gas water heater or a BTU rating for an electric one; the form asks for BTU for gas and kW for electric.
- Entering the flow rate without indicating whether it is based on the 80°F or 100°F rise; the form asks you to indicate which required degree rise is used.
- Giving the tankless flow rate in a unit other than gallons per minute (GPM).
- Leaving out the Make or the Model # for a unit.
- Entering a Storage Tank Capacity in gallons when the tankless system has no storage tank; the column applies only if applicable.
Frequently asked questions
What is the Boulder County Water Heater form?
It is a template from Boulder County Licensing for listing water heater details. It has one table for a standard tank type heater and one for an instantaneous/tankless system, and you complete one or both depending on your water heater type.
Is the Water Heater form a Boulder County property tax form?
No. The form asks only for equipment data: make, model number, BTU or kW rating, flow rate and storage tank capacity. It has no owner, parcel or tax fields and is not used to pay or appeal property tax.
Which table do I fill out for a tankless water heater?
Use the Instantaneous/Tankless Systems table. Enter the make, the model number, the flow rate in gallons per minute and, if there is a storage tank, its capacity in gallons. Indicate which degree rise, 80°F or 100°F, applies to your flow rate.
Do I enter BTU or kW on the Water Heater form?
It depends on the fuel. In the Standard Tank Type Heater table, provide the BTU rating for a gas water heater and the kW rating for an electric water heater.
What do I do about the 80°F or 100°F rise on the form?
In the tankless table, the flow rate column is stated at an 80°F or 100°F rise. The form tells you to indicate which required degree rise will be used for the flow rate you enter, so note one of the two next to the GPM figure.
Can I fill out the Water Heater form online?
Yes. You can fill out the PDF online on FillingPDF and download or print it. FillingPDF is an independent service, not connected to Boulder County, and it does not submit the form; ask Boulder County Licensing where to return it.
Do I need to complete both tables?
Only if you have both kinds of water heater. The form says to complete one or both tables depending on your water heater type, so a single tank heater needs only the first table and a single tankless system only the second.
