Set-Up Kits
Make your installation a breeze with these optional kits to get things done quickly. The Start-Up Kit includes fittings, camps, and even a drill-powered pump to fill the system. The PEX kit includes a 300' length of tubing, two elbows for entering and exiting the floor panels as well as (100) foam staples to secure them to the insulated flooring below your slab. Makes pouring concrete that much easier!
Start-Up Kit
- (3) or (5) - Hose Barb Fittings (see picture below)
- Crimp Tool for 1/2" fittings
- Drill-powered pump to fill the system with fluid
- (10) - 1/2" crimp rings
- (3) or (5) - 1/2" fluid control valves with washers (see picture below)
- Does not include tubing
Fluid Control and Return Fittings
This kit includes a 300' continuous length of tubing as well as elbow bends and 100 foam staples for making installation quick and easy. The bends connect the horizontal enter and exit tubes from the concrete to the vertical lines running up to the boiler itself and eliminate any potential kinking.
Typically it is recommended to use one foot of tubing for each square foot of floor to be heated. This 300' kit will cover 300 square feet and holds approximately three gallons.

FEATURES and BENEFITS
- Fast, organized, and cost-effective
- Mounts to decking, rebar, ready-rod, temporary manifold support, or wooden forms
- A completely enclosed design protects the tubing at the floor surface
- Each channel keeps the supply and return pipes separately and directs them to the correct manifold
- Modular design allows the installer to add as many zones as required
- The reversibility of each module allows individual zones to be piped from opposite directions
- Each module is easily pressed to fit together
- Maintains a larger bend radius than the manufacturers’ recommended minimum of ¾” and smaller PEX tubing
- Constructed of high-impact strength plastic
Boiler System Description and Specifications
This electric boiler system is designed specifically for installation in poured concrete basement and garage slabs that are well-insulated below and around the outside edge of the slab. Use these hydronic heating kits to heat 300, 600, 900, and 1500 feet for every single zone and provide an energy-efficient (approaching 99%) solution for concrete floor heating.
Installation and Owners Manual
How to Choose the Right Size Radiant Floor Boiler
These electric boiler systems are designed so you may install your own radiant floor heat. The pre-assembled boilers make it easy to install and are available with 3, 6, 9, and 11 kilowatts. They are designed specifically for use in poured concrete slabs that are well-insulated around and below the edge of the slab itself. These radiant floor heating kits will heat up to 1500 ft.² in a single zone and the ease of installation, combined with the long-lasting energy efficiency that approaches 99%, make this do-it-yourself heating kit a must-have when heating concrete slabs.
For areas larger than 1500 ft.², please subdivide them and serve them with two or more units dedicated to each area. As an example, a 2,500 ft.² basement could be treated as two, 1,250 ft.² areas each served by one 11kW heater, using 4 loops each. Dual zones may also be used in a single slab.

Electronic Boiler Radiant Heat Questions and Answers
WHY USE RADIANT FLOOR HEAT?
Radiant floor heat is the most comfortable heat available. Warmth radiates from the floor warming our bodies and the objects surrounding us. The radiant heat energy that we pay for rises from the floor to the ceiling instead of being blown in from the ceiling and staying up by the ceiling as with forced air heat, escaping through the ceiling or through open doors.
CAN I USE RADIANT HEAT WITH A GEOTHERMAL SYSTEM?
Radiant used in conjunction with a geothermal system provides a system that is highly efficient, provides unsurpassed comfort as well as extremely flexible. Geothermal systems are available in forced air as well as hydro models. The hydro models create hot water that can be used for radiant heating as well as forced air heating using a fan coil.
WHY DO MOST PEOPLE ONLY TALK ABOUT USING RADIANT HEATING FOR BASEMENT AND GARAGE FLOOR INSTALLATIONS?
Radiant floor heat is most effective in basement or garage concrete floors that are either at ground level or below ground level. Garages and basements commonly meet these conditions and have relatively well-defined heat losses. Less common applications include home additions, workshops, storage sheds, small commercial buildings, etc. Such structures may have more widely varying heat losses. For such applications contact us with a description of your radiant heat floor plans. We are happy to help you choose the appropriate product.
CAN RADIANT FLOOR HEAT BE ADDED LATER?
Unfortunately, there are no low-cost ways to add radiant floor heat to an existing garage or basement concrete floor. If you are building, now is the time to install radiant floor heat.
WHAT IF I WANT MORE THAN ONE TEMPERATURE ZONE?
Zoning a basement or garage concrete radiant floor will require framing thermal barriers between zones before concrete is poured. Otherwise, the efficient heat conductivity of concrete will blend temperature between zones.
DO ALL THE "LOOPS" NEED TO BE THE SAME LENGTH?
Ideally, yes. Unequal length loops create unequal pressure resistance in which the shorter length will tend to more of the water resulting in uneven heat is the result. For good performance with a radiant system, make sure that each loop is nearly equal in length.
WHAT TUBE SPACING IS APPROPRIATE FOR RADIANT HEAT APPLICATIONS?
Spacing depends on several variables including the heat loss of a basement or garage area. In residential areas such as basements, 12-inch spacing is most common. It is helpful to space the first few tubes closer together in an area at ground level as in a basement walkout area where heat loss is greater. Likewise, spacing can be wider where heat loss is less, as where the floor is several feet under the surface of the ground, or in the center of a large space.
DO I NEED TO INSULATE THE BASEMENT OR GARAGE CONCRETE FLOOR?
Basement and garage floor insulation is critically important to keep from losing heat to the outdoors by conduction through the earth, the foundation, or adjacent walls. When the radiant heated floor is not insulated adequately, it may cause dramatically increased energy loss resulting in higher energy bills. Also, the radiant heating unit may not have sufficient output for unintended heat loss.
IS ELECTRIC HEAT AFFORDABLE COMPARED TO GAS WHEN USED IN A RADIANT FLOOR SYSTEM?
You decide, depending on your electric rate. Generally, electric rate increases have not approached the continuing steep rise in propane, natural gas, and fuel oil prices. Examples: If electricity costs you 5¢ per kWh it would compare to propane at 81¢ per gallon, natural gas at 88¢ per Therm, or fuel oil at $1.13 per gallon. Or, if you pay 8¢ per kWh for electricity it compares to propane at $1.29 per gallon, natural gas at $1.41 per Therm, or fuel oil at $1.80 per gallon.
