Where this service usually fits
- Replacing or adding electric baseboard heaters
- Radiant ceiling or wall panel heating
- In-floor electric heating in bathrooms and additions
- Line-voltage and low-voltage thermostat wiring
- Converting a room heated by a portable heater to fixed heat
What moves the price
How the numbers add up: how electrical pricing works
| Cost driver | Why it changes the number | Ask the electrician |
|---|---|---|
| Total connected wattage | Resistance heat is priced by load. Wattage decides circuit count, conductor size and whether the service carries it at all. | What total wattage is this quote based on? |
| Number of separate zones | Each thermostat zone is a control and often a circuit. A whole floor zoned room by room is many circuits. | How many zones and thermostats? |
| Existing service capacity | This is the load most likely to exceed an existing service. The calculation usually decides the project. | What did the load calculation show? |
| Thermostat type | Line-voltage, low-voltage and smart controls wire differently and some need a neutral at the box. | Which thermostat type is specified? |
| In-floor versus baseboard | In-floor systems are set during tiling and cannot be retrofitted afterwards, which ties the electrical schedule to another trade. | When does the electrical work happen relative to tiling? |
| Route from the panel | Heating circuits are often long runs to the far side of a room or an addition. | What routes are assumed? |
Information that changes the scope
- Total wattage of the units being installed
- Existing service size and calculated load
- Whether the space is being converted or already heated
- Thermostat type and where controls will sit
- Whether a heat pump is being considered as an alternative
What an electric heat quote usually includes
- Circuits sized to the connected heating wattage
- Line-voltage or low-voltage thermostat wiring
- Breaker and protection type for each circuit
- Connection of fixed heating units
- Testing and labelling
What is usually NOT included
- The heaters, panels or floor systems themselves
- Flooring, tiling and mortar for in-floor systems
- Removal of existing heating equipment
- Panel or service upgrades the load requires
- Insulation or envelope work
Permits, inspection and code
Electric floor heating carries its own ground-fault requirements. Fixed heaters may not be supplied from general-purpose receptacle circuits, which is why a portable heater and a fixed heater are not electrically equivalent.
Timing and scheduling in Vermont
Plan before the heating season and before any tiling. In-floor systems must be installed during tiling, so the electrical and tiling schedules are interdependent. If a heat pump is under consideration, compare before committing. Resistance heat is cheap to install and expensive to run.
What a clear estimate should address
Separate the heating equipment from the circuit and controls, and confirm whether the quote assumes existing circuits can be reused. Electric resistance heat is a large continuous load and often the item that pushes a service.
Safety boundary
Never run fixed electric heat from an extension lead or a general-purpose receptacle circuit. Fixed heating equipment needs a circuit sized and dedicated to it, and portable heaters are not a substitute for one.
