Frequently Asked Questions (FAQs)

1. Can I replace my thermostat with a smart thermostat?

1. Confirm your system is “low voltage” (24v) The devices most commonly called “smart thermostats”, such as thermostats from Nest, Ecobee, Honeywell, etc., are only compatible with “low voltage” 24v HVAC systems. You should be certain that your HVAC is compatible before you try to hook up a smart thermostat.

2. Is it worth getting a smart thermostat?

The advantage of a smart thermostat is its ability to learn a household's patterns and adjust heating and cooling according to when a home is occupied or is about to be occupied. This reduces the use of heating and cooling systems when nobody is home for significant periods of time.

3. Can a smart thermostat work with any boiler?

Smart thermostats can be used with most any modern boiler. However, some older or damaged boilers will not connect to a smart thermostat. Before buying a smart thermostat, be sure to check its compatibility to ensure it will work with your heating system.
