This is How Thousands of Americans are Heating up Their Homes and Slashing Electric Bills

The national weather services are reporting that it is going to be a SUPER COLD WINTER, maybe one of the coldest for decades. Are you prepared?

For the past few years, the heating industry had just 3 big companies that could set any prices they wanted and kept ripping off customers. A tech startup is turning this $5 billion industry on its head.

The company called Alpha has figured out a way to offer a far superior product (even the biggest tech experts agree) at a fraction of the price.

With almost a million units sold worldwide, this ultra-efficient heater is quickly becoming the most successful device of 2023.

What is it?

Meet the Alpha Heater. A convection ceramic heater with an incredible 99.8% efficiency.

The Alpha company was formed in 2023 by a group of experienced electric engineers from the EV (Electric vehicle) industry.

Their goal was to make a low cost and low maintenance portable heater that is suitable for any home, office or car.
With no installation costs, no maintenance costs and it extremely energy efficient, the Alpha Heater is an engineering masterpiece.

This new type of heater has an incredible 99.8% efficiency. Losing almost no power to energy leakage. It's better for the environment and your wallet.

It heats up any mid sized room within 60 seconds. No other heater is this efficient, but what makes the Alpha Heater special is it's price, ultra-compact design and portability.

In my opinion, this is the next generation of heaters.

It's really easy to set up:

1. Set the Alpha Heater on a flat surface.
2. Plug it in.
3. Set your desired temperature.
4. Wait while this powerful device heats the entire room, car, RV, garage, etc… Up to 500 square feet within 60 seconds!

You can take it anywhere you want, get instant relief from the cold wherever you go.

BUT, it does more than just warm up the room. The Alpha Heater also filters your surrounding air with a built in antimicrobial air filter, making it healthier and easier to breathe. Especially great for those with allergies and/or pets!

No need to worry about noise either, the Alpha Heater is extremely quiet and barely noticeable. Perfect for in the bedroom during those cold winter nights.

How Much Does It Cost?

With similar (less efficient) devices going for $1500+ you would expect the Alpha Heater to be at least this…

But what if I told you that the Alpha Heater retails for $119.99, this is way below your expectations right!

HOWEVER, do you know what's better than paying the already good full $99.99 price?
Their 50% promotional discount, where you can order yours for just $49!
