Similarly one may ask, do I need a special thermostat for radiant heat?

Regular forced air heating thermostats are not well suited to operating radiant floor heating systems. These thermostats turn on the radiant floor when the air is below the temperature setting, and shut off when it's above the temperature setting.

Does it matter what thermostat I buy?

Before choosing a thermostat, you'll need to make sure it's compatible with your heating and cooling system. The most common system types are central heat or central heat and air, which can be 24-volt (V), gas, oil or electric.

Is underfloor heating expensive?

This is because water underfloor heating systems can warm a room more evenly than a radiator can. As a result these underfloor heating systems are more energy efficient and cost a lot less to run than traditional heating methods. The cost of this will depend on whether you have a cheap gas supplier.

Where should I put my underfloor heating thermostat?

Place the thermostat at a suitable height on the wall, usually at the same height as light switches.

How long does underfloor heating take to warm up?

A good guide is between 2 – 8 hours for the full desired temperature using a non-insulated concrete floor. Insulated concrete slab flooring takes slightly less time, between 2 – 5 hours, whilst concrete with 10mm tile-backer insulation can take as little as one hour to heat up.

Are heated floors worth it?

In short, if you already have plans to replace the flooring in a room, then installing in-floor heating is definitely worth it. These radiant heating systems must be installed under the flooring, which means the best time to install heated floors is when you're updating the flooring anyway.

Does a heated floor need a dedicated circuit?

Radiant-floor heating has been around for centuries. The principle is simple: The floor radiates heat to your feet, warming you all over. If you're installing radiant floor heat in an existing room, you'll need a dedicated 15- to 20-amp GFCI-protected circuit to power the system, and an excuse to lay a new tile floor.

Should I turn down radiant heat at night?

Does it pay to turn down the heat at night when you have a radiant-floor heating system? “My opinion is that lowering the setpoint at night is a good thing, as the system will put fewer BTUs into the house, saving energy. When the system ramps up in the morning, it will reheat the slab without any loss of efficiency.
