Choose the Fröling PE1 when you:

Want higher efficiency

Perfect for homes and small commercial spaces, the PE1 wood pellet boiler operates at up to 95% efficiency, maximizing heat output from each pellet while minimizing fuel consumption. Its lambda-controlled combustion and automatic heat exchanger cleaning maintain consistently high efficiency and low emissions throughout its operation.

Strive to be eco-friendly

Whether you are wanting to be more eco-friendly at home or your company is starting a green initiative, wood pellets are a renewable and sustainable resource. Pellets are made locally and dollars spent on wood pellet fuel remains in your local economy.

Want something simple

Fully automated and internet ready, the Fröling PE1 wood pellet boiler lights itself, regulates combustion, cleans its own heat exchanger, and moves ash into a sealed container that only needs emptying after hundreds of hours of operation.

Smart Features for Simplified Operation

The Fröling PE1 wood pellet boiler is engineered for convenience and reliability.

Its innovative systems handle combustion, cleaning, and ash management, so you won’t have to.

Automatic wood pellet boiler comfort 

The Fröling PE1 is a fully automatic wood pellet boiler that can run for over a month with minimal user input. It modulates to meet heating demand, uses very little power, and features a long-lasting hot surface igniter.

Its self-cleaning sliding grate also helps retain heat when idle, and the flexible pellet vacuum system simplifies installation and noise control. With powerful automation, the PE1 delivers clean, quiet, and consistent heat, making it a smart replacement for oil, gas or electric systems in homes and businesses.

Innovation

The Fröling PE1 features an automatic sliding grate that clears ash while managing secondary air and chimney shut-off. A durable, low-wattage igniter lights the boiler without touching fuel, and dual safety gates offer maximum burn-back protection.

Ash is compacted automatically, allowing long intervals between cleanings. The easy-to-remove ash box makes occasional emptying quick and straightforward, and no special tools or training are needed.

Speed-Regulated Draft Fan with Lambda Sensor

The Fröling PE1 uses a speed-regulated fan and exhaust sensors to adjust output based on fuel type and combustion needs, ensuring clean, efficient performance at all times. Oxygen control technology guarantees a cleaner burn, even with pellet variation.

A user-friendly touchscreen tracks fuel use, maintenance, and system performance, with internet connectivity for remote access. Despite its power, the PE1 fits neatly in a 3’x3’ space and includes automatic ignition and built-in safety features for peace of mind.

Self-Cleaning and Ash Management

The Fröling PE1 self-cleans its combustion grate and heat exchanger to maintain safe, efficient performance. Ash is compacted into a suitcase-style container that's easy for homeowners to remove.

By design, the system is low-maintenance, and when service is needed, the PE1’s accessible layout allows professionals to perform quick, cost-effective tune-ups.

Connectivity

Fröling Connect enables 24/7 remote monitoring and control from any web-enabled device. You can check settings, track performance, and receive real-time alerts, like when the ash box needs emptying.

The system also stores historical data and allows multiple users, so family members or technicians can easily assist with boiler operation.

What Our Clients Say About Us

Kevin from Maine: PE1 20 w/ Cube Pellet Storage

I love my Fröling PE1 pellet boiler as compared to my previous pellet boiler. It uses less wood pellets and is way more efficient. I currently only clean it once a year and this boiler is used year round. My previous pellet boiler was cleaned roughly every 3 to 4 weeks. I also bought a variable speed circulating pump from Froling Wood Boilers, which I find to be an excellent pump. The pellet boiler itself tells the circulating pump how fast it needs to turn, it has a sensing line. Overall I am very happy with my decision to purchase a Fröling pellet boiler.

I’m in the second season of using my Fröling PE1 pellet boiler and I love it!
