Lithium Battery Heating System

This lithium battery is very reliable.

Great quality battery, no over heating issues, and reliable.

This manual flash has everything I need and especially like the lithium battery. just bought a second unit.

Long lasting Lithium battery makes it cost effective.

Lithium without the need to recharge. Excellent long-life battery.

I bought one, have to buy another, great sony lithium battery.

The Watson Lithium Battery is a great backup for a Nikon battery. It lasts as long and makes a great back up for a Nikon battery.

I love the Ecobee, and definitely recommend it. It's way more accurate than my old Honeywell. The external sensors help keep the temperature even through out the main floor. It wasn't exactly plug and play for me as my boiler/radiant floor heating system didn't have a C-wire to tap into. I Googled myself and used their tech support for installation advice. After figuring out the wiring challenges with a work around done (took me 2hrs) to have my Ecobee up and running. So it could be an easy to advanced difficulty DIY project depending on your heating/cooling system.

Thermostat was NOT recommended for my 'old' heating system wiring set-up, noting it would probably require a c-wire. After a pretty extensive web search (rather than using the enclosed converter), it was a pretty easy operation (at least for this guy with 'some' experience and a little tenacity) to locate a terminal in the old Aquastat (at least my version) that functioned just fine as a c-wire. Thermostat compatibility with both Alexa and Google Home are both excellent and easy to set-up. Firmware update provided even more features and easy operation for everyone in the home. One of the best tech buys in a long time, especially considering a local gas company $100 rebate! Very cool stuff. Kudos to all at Ecobee.

My heating system has 4 zones each with a eccobee3 and I added a remote sensor for each. I had to upgrade the wiring to get three wires, but it was worth it! I have everything tied into Apple HomeKit which was a must for me. The heat is so much more even now thought the house. I'm very happy with the setup.
