The complete HUG 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 complete system has nine 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 five loop pumps can manage from 1,500 sq. feet to 3,000 sq. feet with splitters using one heat source pump.
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 approximately 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.
HUG Hydronics is the easiest in-floor heating hydronic unit to install and does not require professional tools. It takes about an hour to install a HUG Hydronics tank once the water heater and floor pipes are installed.
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; push silicon hoses onto the PEX floor pipes and secure them with a clamp (provided).
Any source of hot water rated for home heating can be directly hooked up. The easiest is an electric tankless water heater by AO Smith. The 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 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 geothermal, we currently do not have the high flow rate geothermal heat pumps required at this time.
The HUG system is an open-loop system. The system is not recommended for pressurized radiator systems.
The tank should not be installed two or more floors below the floor to heat.
HUG’s main reason to exist is to help make people 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 hydronic systems can be changed with no tools and basic tools in just a few cases—one of the only Hydronics or Radiant heating systems you can easily fix yourself.
HUG Hydronics in-floor heating systems can use any hydronic fluid or water. The best is water purified by reverse osmosis. The second best is softened water. Tap water works fine, but it might have minerals and bacteria 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.
The recommended PEX is 1/2 inch. Silicon Hoses are provided with the unit for a standard installation. They are high-quality 1/2-inch ID silicone.
