Will it work with my heating system?

Mysa Lite works with electric baseboard, fan-forced convector, self-contained hydronic baseboard, and radiant ceiling heat — all line-voltage systems. It's not for central HVAC, millivolt gas fireplaces, or boiler-fed hydronic heat. Take our 1-minute compatibility check before you head to the warehouse.

How do the rebates work in my province?

It depends on the province. Enter your postal code above to see the warehouse price where you are. Québec, Nova Scotia, and New Brunswick each run their own rebate, and it is paid by the program after you buy, not taken off at the Costco till. At the in-store demo days, a Mysa staff member can walk through the rebate for your province.

Is this the same Mysa sold on getmysa.com?

Yes. It's the same Mysa Smart Thermostat Lite for electric baseboard heaters. The Costco 4-pack, item #4000244901, is sold in warehouses in Québec, Nova Scotia, and New Brunswick.

Who do I contact for installation help or returns?

For installation help, contact Mysa support. The team is based in Canada, in the app and at getmysa.com. For a return or an exchange, go through Costco. Follow local code, and hire a certified electrician if your province requires it.

Can I buy the 4-pack online instead?

Yes, this item is currently available on Costco.ca. The price may differ from your local warehouse in-store price. The utility instant rebate at checkout is only available for an in-store purchase.
