Radiant floor heating installations require specialized knowledge and precise material calculations. EstimateKit helps hydronic heating contractors create accurate radiant system estimates with pre-loaded materials for tubing, manifolds, controls, and heat sources. Whether you're installing hydronic radiant in new construction or retrofitting electric radiant in a bathroom remodel, proper estimating ensures profitable projects. Radiant work commands premium pricing—contractors who specialize in these systems can achieve higher margins than traditional forced-air installations.

Why Radiant Heating Estimating Is Specialized

Tubing layout calculations based on room size, heat loss, and floor covering type require careful planning

Manifold sizing depends on the number of zones and total tubing length in the system

Heat source selection (dedicated boiler, combined DHW, heat pump) affects system design and cost

Floor covering compatibility impacts tubing spacing and water temperature requirements

New construction vs. retrofit installations have dramatically different labor requirements and material needs

EstimateKit Features for Radiant Heating Jobs

Radiant tubing calculator

Enter room dimensions and calculate tubing requirements based on spacing (6", 9", 12") and coverage pattern. Automatic waste factor included.

Manifold configuration

Select manifolds with appropriate zone capacity and flow controls. Pre-configured with isolation valves, air vents, and fill/drain connections.

Heat source integration

Quote complete systems including boilers, buffer tanks, mixing valves, and controls. Or quote radiant distribution only for boiler-only contractors.

Floor covering adjustments

Adjust pricing and specifications based on floor covering: tile, hardwood, carpet, or LVP. Different R-values require different system designs.

Electric radiant option

Quote electric radiant mat systems for bathrooms and small areas where hydronic isn't practical. Mat sizing and thermostat selection included.

New construction vs. retrofit templates

Pre-built estimates for slab-on-grade new construction, suspended floor staple-up, and above-floor overlay installations.

How to Price Radiant Heating Work Profitably

Radiant heating is premium work that commands premium pricing. Contractors with radiant expertise can charge 25-40% more than general HVAC contractors.

Hydronic radiant material markup typically runs 35-45% including tubing, manifolds, and controls

Labor for new construction radiant runs $3-6 per square foot depending on complexity and floor type

Retrofit installations require 2-3x the labor of new construction due to access challenges

Control systems (thermostats, outdoor reset, mixing valves) add $500-2,000 to material costs but offer high margins

Design time should be included in pricing—radiant systems require more planning than forced-air installations
