Quick Answer: EffeUno is an Italian brand that’s been handcrafting electric countertop pizza ovens since 2007. The P134H 509 PRO (commonly listed $1,450-$1,750) and higher-power P134HA 509 PRO (commonly listed $1,600-$2,100) both use a genuine Biscotto di Sorrento clay stone and hit 500°C (932°F) per EffeUno’s own spec sheet — independent testers have pushed one past 1,000°F with extended preheat. Both need a 240V circuit, which is the main catch for most US kitchens.
EffeUno is one of the more specialized picks on this site: a fully indoor, fully electric oven built for people who want Neapolitan-level heat without a backyard or a gas line. It shows up across specialty importers like The Pizza Oven Store and Black Rock Grill rather than big-box retail, and it’s positioned well above the budget-import field we usually cover. We pulled specs from EffeUno’s own product pages and an independent hands-on review to see where it actually fits.
EffeUno pizza ovens by the numbers
- 500°C (932°F): the maximum stone temperature EffeUno rates the P134H/P134HA 509 line for, per the brand’s own spec sheet — well past the ~905°F the AVPN requires for authentic Neapolitan pizza.
- 1,000°F+: the temperature an independent reviewer (Pala Pizza Ovens) measured on a P134 with extended preheating, roughly 30 minutes to reach maximum from cold.
- ~9-17cm: the chamber height range across EffeUno’s line — the standard P134H runs a lower 9cm chamber for classic Neapolitan pies, while the taller P134HA variant opens up to 17cm for bread and thicker bakes.
- 240V: the electrical requirement for the full P134 line, the same circuit type that powers a household clothes dryer — not a standard 120V US wall outlet.
EffeUno P134H vs P134HA at a glance
| Model | Power | Stone | Max temp | Chamber | Price | Best for |
|---|---|---|---|---|---|---|
| P134H 509 PRO | 2.8kW | Biscotto di Sorrento | 500°C / 932°F | 9cm (low) | ~$1,450-$1,750 | Neapolitan-focused bakers |
| P134HA 509 PRO | Higher-power element | Biscotto di Sorrento | 500°C / 932°F | Up to 17cm (tall) | ~$1,600-$2,100 | Faster recovery, bread too |

The P134H is EffeUno’s standard entry point into the P134 line, and its low 9cm chamber is purpose-built for classic Neapolitan pizza rather than general baking. Where a Breville Pizzaiolo tops out around 750°F, the P134H’s Biscotto stone and 500°C ceiling put it in the same real-world heat territory as a gas-fired Ooni Koda — indoors, on standard electric power, with no propane tank or backyard required.
2. EffeUno P134HA 509 PRO — Taller Chamber, Faster Recovery
EffeUno P134HA 509 PRO Electric Pizza Oven
- Same Biscotto stone and 500°C ceiling as the P134H, in a taller up-to-17cm chamber.
- Higher-power heating element shortens the recovery time between back-to-back bakes.
- Extra headroom also handles bread and thicker New York-style pies, not just Neapolitan.
The P134HA doesn’t chase a higher stone temperature — both models share the identical 500°C ceiling per EffeUno’s spec sheet. Instead it buys chamber height and recovery speed: the taller cavity fits bread loaves and thicker crusts the low-profile P134H can’t clear, and the stronger element gets back to bake-ready temperature faster between pizzas. Both models are also sold in a smart-control “509E Evolution” trim (PID regulation, digital display) for roughly $300-$500 more than the PRO trim reviewed here.
How EffeUno compares to the field
| Oven | Claimed max temp | Fuel | Price |
|---|---|---|---|
| EffeUno P134H | 500°C / 932°F | Electric (240V) | ~$1,450-$1,750 |
| EffeUno P134HA | 500°C / 932°F | Electric (240V) | ~$1,600-$2,100 |
| Breville Pizzaiolo | 750°F | Electric (120V) | $999.95 |
| Ooni Koda 12 | 950°F | Gas (propane) | $349 |
| WPPO Le Peppe | 900°F | Wood (gas optional) | ~$149.99-$299.99 |
The pattern: EffeUno is the hottest indoor electric option on this site by a wide margin, but it’s also priced closer to a premium outdoor multi-fuel setup than a countertop appliance. A Breville Pizzaiolo plugs into any standard 120V outlet and costs under $1,000, trading roughly 180°F of stone heat and true Biscotto clay for real convenience. EffeUno’s field is really “serious indoor pizza makers who already have or can add 240V access,” not a general kitchen-appliance buyer.
Who should buy an EffeUno pizza oven
- Buy the P134H if Neapolitan pizza is the priority, 240V access already exists (or is affordable to add), and the low chamber height isn’t a limitation.
- Buy the P134HA if bread, thicker crusts, or faster back-to-back recovery matter alongside Neapolitan pies.
- Consider the Breville Pizzaiolo instead if 120V-only power and a sub-$1,000 budget matter more than the extra ~180°F of stone heat.
- Consider an outdoor gas oven instead if a backyard setup is an option — an Ooni Koda or similar gets close to EffeUno’s temperature range for a fraction of the price, just outdoors instead of on a countertop.
Whichever model you land on, budget for a real pizza peel — EffeUno ships the Biscotto stone but not a peel — and see our best indoor pizza oven and best electric pizza oven guides for how it stacks up against the rest of the countertop field.
Pizza Peel
- A perforated or wooden peel makes launching onto a hot Biscotto stone far less messy.
- See our pizza peel guide for picks that fit a 9-17cm chamber.
The bottom line
EffeUno’s P134 line is the hottest indoor electric pizza oven we’ve reviewed on this site, built around a genuine imported Biscotto stone rather than the cordierite or steel most countertop ovens use. The P134H suits Neapolitan-focused bakers with 240V access, while the P134HA’s taller chamber and faster recovery justify the step-up price for anyone also baking bread. Neither is a casual buy at $1,450+ and a 240V requirement — for that, a Breville Pizzaiolo or an outdoor gas oven from our best outdoor pizza oven roundup will get most home cooks most of the way there for far less.
