BoilerMaker Surface™ – The Best Electric Brew Kettle. Period.

Lifetime Warranty!

The BoilerMaker Surface™ Brew Kettle revolutionizes brewing with its cutting-edge design, empowering brewers to clean less and brew more. Crafted from high-quality stainless steel with a brushed finish, it features ports in either NPT or Tri-Clamp orientation for versatile setups. Powered by Electric Surface Heating Technology, the heating element is bonded to the kettle’s underside, eliminating the hard-to-clean immersion heater. This makes your brew day faster, easier, and hassle-free. Available in 10-gallon (3500W/240V) and 20-gallon (5500W/240V) models, it’s perfect for brewers seeking convenience and precision.

Best Construction

Made from premium stainless steel, the BoilerMaker Surface™ features a sleek brushed finish that hides fingerprints and water stains, keeping it looking impeccable for years. The silky-smooth interior ensures easy cleaning, while high-impact glass-filled nylon handles are durable, heat-resistant, and cool to the touch. The open top lip prevents water from trapping during cleaning, avoiding drips and stains. Blichmann Engineering pioneered the 1.2 height-to-diameter ratio, ensuring consistent performance. Robotically welded 1.5″ Tri-Clamp ports add durability and customization options, making this kettle a reliable centerpiece for any brewery.

Why Choose the BoilerMaker Surface™?
US Patent & Patent Pending Electric Surface Heating Technology eliminates immersion heaters, reducing cleaning time. Ultra-low watt density evenly disperses heat across the kettle bottom for precise temperature control. Eliminates the need for external mash heating methods like HERMS Coil or RIMS Rocket. Step mashing and maintaining mash temperatures are simpler without complicated recirculation loops.

Pair with the BrewCommander™ Brewhouse Controller for accurate temperature regulation, enhancing your brewing precision.

Patented G2 Linear Flow Valve

The patent-pending G2 linear flow valve offers precise flow control for sparging, lautering, and chilling, improving repeatability. Its 90-degree outlet rotates for kink-free hose routing, eliminating extra fittings. The valve disassembles in seconds for quick cleaning, and the cool-touch silicone grip handles up to 600°F without melting, unlike vinyl grips. The parabolic valve stem ensures linear flow—25% open equals 25% flow—making adjustments intuitive (see flow graph for details). Optional patented features include the button louver false bottom for high efficiency and plug resistance, and the HopBlocker™ to keep hops and hot break out of your fermenter.

Designed for Brewers
Exclusive snap-in dip tube installs without tools, draining to within 3/8” of the kettle bottom. Patented stepped ledge supports the mash screen, eliminating sidewall shunting. Adjustable BrewMometer™ with a patented brewing dial face for ultimate convenience. Heavy-duty borosilicate glass level gauge with stainless steel guard, engraved graduations, and clean-out ports; doubles as a mash manometer.

Thoughtful touches include handle orientation for easier carrying and a lid that stores on the kettle handle, enhancing usability in any brewery setup.

Quality and Assembly

All BoilerMaker Surface™ and G2 Brew Kettles come with a lifetime warranty and are assembled in Lafayette, Indiana.

Crucial to optimal performance of your new BoilerMaker™ Brew Kettle is selecting the size that best fits your needs. Selecting a brew kettle, mash tun, or hot liquor tank that’s too small or too big can cause frustration and poor performance.

Boil Kettles: We recommend always doing a full wort boil, as do most brewing texts and advanced brewers. This minimizes the addition of top-up water to compensate for boil-off, and starting with the volume called for in your recipe will let you know early in the process if you’ve hit your target gravity, giving you more time to correct the problem. Also, you’ll get more consistent hop utilization by sticking to the recipe volumes, as utilization changes significantly with specific wort gravity. Last, but certainly not least, is boil-over prevention. Having enough head space will keep this irritating problem at bay.

We recommend a boil kettle approximately 2 times the size of the finished batch size. Although this may seem a bit much, a 10 gallon batch will typically start with a 13 to 14 gallon pre-boil once you compensate for cooling contraction, transfer losses, and boil-off. This will allow for a reasonable head space to reduce boil-over problems. For example, if you’re a 10 gallon batch brewer, you’d select the 20 gallon BoilerMaker™ brew pot as your boil kettle.

Mash Tun Vessels: We recommend filling your mash tun vessel to no more than 80% of capacity. This will allow sufficient space for dough-in of the grains and additions of sparge water and sparge arms, etc. The chart below includes various water-to-grist ratios to assist you in your selection. The green column is our recommended water-to-grist ratio. Minimum volumes are to ensure that the thermometer probe is adequately submerged and also that you have an adequate grain bed depth for proper wort filtration. We’ve designed the BoilerMaker™ brew kettle sizes to seamlessly blend from size to size, so you’ll never need to sacrifice.

Hot Liquor Tanks: We recommend sizing your Hot Liquor Tank (HLT) to the same size as your mash tun to ensure you have plenty of sparge water available on brew day.

Recommended Three Kettle Systems For Typical Batch Sizes (HLT / Mash / Boil):

5 gal batch: 7.5/7.5/10 or for high gravity beers consider a 10/10/10 10 gal batch: 15/15/20 15-20 gal batch: 20/20/30 32 gal batch: 55/55/55 (recommended) or 30/55/55 64 gal batch: 100/100/100 (our 55 gal pot with the 2bbl extension)

We offer a hole plug so that you can install the BrewMometer™ in multiple locations, perfect for multiple batch sizes in one kettle!
