Before AviTherm, I dealt with frozen bird baths every single morning. Now my cardinals and finches enjoy fresh water all winter, and setup took less than five minutes.

Based On Real and Honest Experiences
I live in northern Minnesota, and AviTherm kept my bath ice-free even at negative ten degrees. My energy bill only crept up by a few dollars a month, which floored me.

I doubted a simple thermostat could really cut costs, but three months in, my birds get warm water every day and my electric bill barely moved. Color me impressed.

Q1 How fast does AviTherm warm up the water in my bird bath?
AviTherm typically brings your bath to ice-free temperatures within 15 to 20 minutes of plugging in. Exact timing depends on outdoor temps and bath size, but most birds have fresh water fast.
Q2 Does AviTherm hold up in extreme sub-zero cold?
Absolutely. AviTherm's 70W heating core keeps working reliably even when temperatures plunge well below zero, so your birds always have access to liquid water.
Q3 Is AviTherm safe to have around birds?
Yes. The heating element is fully enclosed and thermostat-controlled, so it never gets hot enough to harm your feathered visitors while they drink and bathe.
Q4 What will AviTherm cost me in electricity each winter?
Most owners spend roughly $8 to $12 a month running AviTherm. Because it only heats when needed, you get warm water without a big spike in your bill.
Q5 Can I use AviTherm in a plastic or ceramic bird bath?
Yes, AviTherm is safe for plastic, ceramic, and metal baths alike. Its built-in thermostat keeps temperatures in a safe range that won't damage any material.
Q6 Do I need to remove AviTherm when winter ends?
You can technically leave it in year-round, but most owners unplug, clean, and store AviTherm once temperatures rise for the season.
Q7 Will the thermostat really cycle on and off to save power?
Yes. AviTherm automatically stops heating at 104°F and kicks back on at 77°F, repeating this cycle all season to keep energy use as low as possible.
Q8 How do I clean AviTherm after the winter season?
Unplug AviTherm, lift it from the bath, and wipe it down with a damp cloth. Avoid submerging the electrical components, and let it dry fully before storing.
