Heater Guides is a hands-on resource for homeowners. We break down space heaters, water heaters, fireplaces and HVAC systems into plain-English buying guides, real reviews and step-by-step fixes — so you pick the right unit and keep it running.
Three routes into the site. Pick the one that matches where you are right now — shopping, fixing, or just trying to understand how the thing works.
Sizing charts, honest reviews and head-to-head comparisons so you buy once and buy right.
Symptom-first troubleshooting: no hot water, pilot won’t stay lit, leaking tank, tripping ECO.
How convection, radiant and infrared heat actually differ — and which one suits your room.
Explore the basicsNine core categories cover almost every question we get asked. Each hub collects the reviews, sizing advice and repair walkthroughs for that type of unit.
Newly published and recently updated, so the specs, prices and part numbers still match what is on the shelf.

Every guide on Heater Guides starts with a real problem in a real house: a cold basement, a tank that runs out mid-shower, a garage that never gets above 50°F. We buy or borrow the units, run them, take them apart when they fail, and write down what we learn.
Where a job crosses into gas, venting or electrical work that needs a permit, we say so plainly instead of pretending everything is a weekend DIY.
Meet the teamA good rule of thumb is 10 watts of electric heat per square foot of floor space in an average, insulated room — so a 1,500-watt heater comfortably handles about 150 sq ft. Add 20–30% for high ceilings, poor insulation, a basement or a garage, and subtract if the room is already served by central heat.
Electric resistance heaters are 100% efficient at the unit but electricity usually costs more per unit of heat than natural gas, so gas is normally cheaper to run where a gas line already exists. Electric wins for a single room, for zoned use where you heat only the space you occupy, and when the alternative is running a whole central system.
The three usual causes are an undersized tank for the household, a failed lower heating element or thermostat, and sediment build-up that steals tank capacity. Our troubleshooting guides walk you through telling them apart in a few minutes with nothing more than a multimeter and a bucket.
No. We choose what to cover ourselves, and no brand pays for a placement or a rating. Heater Guides earns a commission when you buy through some of our links, at no extra cost to you — that is what keeps the guides free.
Many electric units are a genuine DIY job if you are comfortable with a breaker panel and can follow clearance requirements. Anything that involves gas piping, venting a combustion appliance, or altering a flue should be signed off by a licensed pro — the safety guides on this site tell you exactly where that line sits for each type.
Start with our sizing and buying guides — they walk you from square footage to the exact wattage, BTU and fuel type that makes sense for your space.
