1 |
How large of an area can a HUG Hydronics in-floor heating unit heat? |
|
Ans: The HUG full in-floor heating system with splitters can deliver in-floor heat for up to 5,400 square feet under normal conditions with standard insulation construction. The in-floor heating full system has 9 pumps for floor loops with one heat source pump. Each floor loop pump can heat 300 sq. feet & with HUG pump splitters it can increase to 600 sq. feet. The mid-size package with 5 loop pumps can manage from 1,500 sq. feet to 3,000 sq. feet with splitters using one heat source pump. |

How much space does a HUG Hydronics in-floor heating unit need to operate? |
|
Ans: The tank is 22 inches tall, 33 inches wide, and 17 inches deep. Please allow 24” to 30” in front of the tank for service access & about 1” inch on each side to install. The tank typically sits on the floor in front of the pex pipes & requires about 1 to 2 inches from the wall depending on the PEX location. For planning a new installation, the recommended floor space required is 36” wide (91cm) x 18” (56cm) deep plus 24” (63cm) in front of the tank to service. About 12” is needed above the tank for cover removal. Typically a tankless water heater is mounted on the wall above the tank. Refer to heater specifications for needed space. |

Is this in-floor heating unit complex to install and maintain? How much time is required to install the HUG Hydronics in-floor heating unit? |

What tools are needed to install? Do I need any special tools to install a HUG Hydronics in-floor heating unit? |
|
Ans: The only tools required are a small screwdriver & pliers assuming the water heater is installed and the thermostat wire is run. The HUG Hydronics in-floor heating unit only needs a screwdriver to connect the thermostat wire. All the plumbing requires no tools; you just push silicon hoses onto the pex floor pipes and secure with a clamp (provided). |

What heat sources can I attach to my HUG Hydronics in-floor heating Unit? |
|
Ans: Any source of hot water that's rated for home heating can be directly hooked up. The easiest is an electric tankless water heater by AO Smith. Second easiest is a gas tankless water heater. HUG is constantly testing water heaters to find the best value, ease of use and ease of repair, and so far our favorite is AO Smith. The HUG Hydronics installation manual and application notes show how to hook up to several other kinds of heat sources. You can also use multiple heaters for off peak heating applications or for using solar or wood heat with a heat exchanger. As much as we love the idea of matching up with geo-thermal, we currently do not have the high flow rate geo-thermal heat pumps require at this time. |

What hydronic systems or installations are not recommended? |
|
Ans: The HUG system is an open loop system. The system is not recommended for pressurized radiator systems. The tank should not be installed 2 floors or more below the floor to heat.

Can I make my own repairs or is the HUG Hydronics in-floor heating system best repaired through a professional? |
|
Ans: HUG's main reason to exist is to help make people be more resilient. Being able to fix things in your home helps toward that goal. The HUG Hydronic system was designed with that foremost in mind. Most parts in the hydronics system can be changed with no tools, and with basic tools in just a few cases. One of the only Hydronics or Radiant heating systems that you can easily fix yourself. |

What fluid can I place in my HUG Hydronic in-floor heating unit? What do you recommend? |
|
Ans: HUG hydronics in-floor heating system can use any hydronic fluid or water. The best is water purified by reverse osmosis. Second best is softened water. Tap water works fine, but it might have minerals and bacteria in it that are undesirable to humans and heaters. If you add propylene glycol antifreeze, we suggest about 33% (one part antifreeze to 2 parts water), but 50% can be used. |

|

What size PEX do you recommend for a HUG Hydronics in-floor heating unit? |
