No fans. No cycling noise. No 3am wake-ups when the heater kicks on. Oil-filled radiators heat silently and stay warm even after turning off. Your bedroom stays quiet and comfortable all night.
No exposed elements. No fire risk.
Built-in overheat protection and tip-over safety switch. The surface stays warm, not scorching hot. Safe around kids, pets, and curtains. Place it in a nursery without worry.
Heat that stays. Even when it's off.
Unlike ceramic heaters that cool instantly, oil-filled radiators retain heat for hours. The Thermal Studio keeps warming your room long after cycling off - maintaining temperature without constant energy use.
The Problem
Your space heater is keeping you awake.
Fan heaters blast dry air and wake you up every time they cycle on and off. Ceramic heaters have exposed elements that worry you around kids and pets. The Thermal Studio uses oil-filled technology - silent operation, no dry air, and heat that lasts even after it turns off. Warmth without compromise.

Finally slept through the night without waking up cold
Our furnace cycles on and off all night - room gets warm, furnace shuts off, room gets cold, I wake up. Repeat until 6am. This radiator keeps my bedroom at a steady temperature all night. No cycling noise, no temperature swings. First full night of sleep I've had in months. My wife noticed I'm less grumpy in the morning.

My baby sleeps better and I worry less
Was terrified of space heaters in the nursery - hot coils, fire risk, all of it. This has no exposed elements and auto-shuts off if tipped. Surface is warm but not burning hot. Baby sleeps through the night in a cozy 70 degrees and I don't lie awake worried about fires. Peace of mind was worth every penny.

Basement office went from freezing to comfortable
WFH in my basement where the heat barely reaches. I was wearing a jacket indoors and my hands would go numb typing. This thing changed everything. Roll it next to my desk and I'm comfortable all day. Silent too - no fan noise during Zoom calls. Best home office investment I've made.

No more dry skin and nosebleeds
Forced air heat destroys my skin every winter. Cracked hands, bloody noses, staticky hair. This radiator heats without blowing air so humidity stays normal. My dermatologist asked what I changed because my skin looks so much better. Just switched to oil-filled heat. Game changer.

Quiet enough for my home studio
I record voiceovers at home. Every heater I tried added noise to my recordings. This one is dead silent - no fan, no clicking, nothing. I can record while it runs. Only downside is it takes a bit to warm up. But once it's warm, it stays warm. Worth the wait.

My cat approves
My old space heater had exposed coils - always worried my cat would burn herself. This has a warm but not hot surface. Now she curls up right next to it and purrs all day. Safe for curious pets who like to investigate everything. One less thing to stress about.

Heat stays even after turning it off
Turned it off before bed thinking I'd wake up cold. Woke up still warm. The oil retains heat way longer than I expected. Room was still comfortable 3 hours later. This is the opposite of my ceramic heater that cools down the second it switches off. Impressive.

Guest room is finally usable in winter

Electric bill barely moved
I was worried about running a 1500W heater. But I'm not heating my whole house anymore - just the room I'm in. Turned central heat down to 62 and use this in my office. Electric bill went up maybe $15 but gas bill dropped $40. Net savings. And I'm actually comfortable now.

Instead of heating my whole house to 72, I keep central at 65 and use this in whatever room I'm in. Gas bill dropped $40 last month. Electric went up maybe $15. Net savings every month. And I'm actually warmer because the heat is right next to me instead of blowing from a vent across the room.

Cheap space heater: $40. Makes noise. Dries the air. Gets dangerously hot. Burns out in 2 years. This: under $200, silent, gentle heat, built to last. The math is easy. Spend a little more for something that actually works safely. Still on year two with no issues.

Three heat levels = three situations covered
Low for sleeping (gentle background warmth). Medium for working (nice steady heat). High for when you come home to a cold room (warms it fast). I actually use all three depending on the situation. Nice to have options instead of just 'on' and 'off.'

We get it - you've probably been burned by cheap space heaters that barely work. This is different. Within 30-45 minutes, your room will be noticeably warmer. The oil retains heat, so even when it cycles off, your room stays comfortable. Over 32,000 customers have become believers.
This is exactly why people choose oil-filled radiators. No exposed heating elements. No burning hot surfaces. Built-in overheat protection and tip-over auto shut-off. The surface gets warm but not dangerously hot. Safe for nurseries, around curious pets, and next to furniture.
Many customers actually see their heating bills go DOWN. Instead of heating your whole house to 70, keep central heat at 62-65 and use this in the room you're in. Zone heating is more efficient than whole-house heating. You're heating one room, not five.
30-day money-back guarantee. If it doesn't warm your room, send it back. We've shipped over 32,000 units and most people end up buying a second one for another room. But if you're in the small percentage it doesn't work for, you're covered.
