Trusted patio heater picks for people with a cold patio and a budget. How much heat your space actually needs, what it costs an hour at real published energy prices, and what survives the wind.
Everyone in this category says they tested twenty heaters. We have not tested any, and we say so. What we do instead: compile the published specs, compute the gas and electrical load from them, cite the maker’s own manual, and show the arithmetic so you can check it. The full method.
What we’d buy in each category
The top pick from each roundup, with the price where a live one exists. Every one links to the comparison it won, so you can see what it beat.
The published-radius honesty test. One of the very few towers whose maker publishes a coverage radius rather than a vague area, and the 9 ft figure survives the arithmetic. That alone puts it ahead of most of the field.

Wind, and anywhere with a roof. Radiant heat that a breeze cannot blow out, on a plug. 1,500 W is only 5,118 BTU/h, which sounds like nothing next to a propane tower and lands far more of itself on you.

One table, four people. 11,000 BTU heats a table, not a patio, and being clear about that is the whole point. For a bistro table on a balcony it is the right size and nothing bigger fits.
The wettest exposed spot. IP55 is the highest published ingress rating in this roundup, which makes it the one to mount where rain actually blows in sideways. Everything else about it is a standard 1,500 W infrared unit.
Ordered fault trees for a heater that will not stay lit, an electric unit that stopped, and the parts that fix each.
The page this site is built around
How much heater does your patio need?
Every publisher in this category gives you a number. Almost none shows you where it came from. Ours multiplies your area by a published rule, corrects for whether there is a roof and how exposed the spot is, and prints every step — so you can disagree with a specific factor rather than with a conclusion.
It also tells you what that output costs an hour on propane and on electricity, and how long a 20 lb cylinder lasts at that burn rate.

It does not change what we recommend, and the thing that keeps it honest is that every figure on this site has its arithmetic on the page.
