How We Research
Every guide on MellowMantel starts with one question: will this product work for the person who is shopping for it? For our patio heater guides, that means your porch, deck or patio and the way you plan to use it outdoors.
Here is how we answer it.
1. We start with the outdoor space
The space decides the heater. A small porch, an open deck and a wind-prone patio call for different picks.
Patio heaters are for outdoor use only. We never suggest using one indoors or in a closed garage, and we say what to measure for clearance from walls, ceilings and anything that burns.
2. We compare specs and features
We look at heat output (BTU for propane, watts for electric), fuel type, height, wheels, tank housing, ignition and tip-over shut-off. For electric models we note the plug or mount type.
Makers describe their heaters in their own words, so we name the brand for every claim. We also note the warranty terms the maker lists.
3. We look at buyer feedback
We read through what buyers report after using a heater. We look for patterns, like ignition that fails, flames that go out, wobbly bases, rust or missing parts.
One angry review doesn't sink a product. A pattern does.
4. We score each product
Our score weighs specs, features and buyer feedback against what you're shopping for. A product that's great for one home may score lower in a guide written for another.
Scores spread out on purpose. A 10 is rare.
5. We keep pages up to date
Products change, and some disappear from stores. Many makers sell several heaters with similar names and BTU numbers, so we check each model name and code, and we only link new units.
When we update a guide, the "Updated on" date at the top changes with it.
What our picks are not
Our picks are research, not lab tests. We don't claim to have used every heater we cover.
Our guides don't replace the maker's manual. For propane tanks, hoses, clearance, lighting and storage, follow the maker's directions and your local rules.
We make no safety promises, and we never describe a heater as safe for indoor use. When a maker makes a claim, we label it as the maker's claim.
