Premium Infrared Glass Heater, White 670W

Heating a room with electricity — what it really costs, measured on this panel

The white Premium Infrared Glass Heater 670 W is the same 1000 × 365 mm glass panel as our black model, in a white glass that brightens a bedroom, living room or office. Our panels report their consumption every hour, so instead of a power rating on a label we can tell you what the 2025/26 heating season actually cost.

The short version. As the only heat source in a correctly sized room, a 670 W panel used about 1 100 kWh from October to April — roughly €255 for the season at Estonian household prices (23.2 c/kWh incl. VAT): about €1.20 a day on average, around €2.05 a day in the coldest month. As supplementary heat in a room that already has heating: about €0.39 a day, roughly €80 for the season. Prices in Latvia, Lithuania and Finland differ; the kWh figures do not.

Three ways to make that number smaller

1. A weekly schedule. Heating the room only when someone is in it took the season from ~1 100 kWh down to ~740 in our data — about €85 saved. The biggest lever, and it costs five minutes in the app.
2. Night and weekend network tariff. A kWh at night is cheaper on most network packages; the panel shifts heating into those hours by itself.
3. Nord Pool automation. The panel reads tomorrow's exchange prices and prefers the cheaper hours. Together with the night tariff this took about 13 % off the bill — less than on a water heater (a room cannot store a night's heat), so we do not promise more.

How it works

1. Mount it on the wall with the bracket in the box — four screws, about 10 minutes. No electrician: it plugs into an ordinary socket.
2. Connect it in the GPO Home app (Wi-Fi or Bluetooth) and set the temperature you want in the room.
3. Set the weekly schedule, or switch on Nord Pool mode and let the panel choose the cheapest hours.

Will 670 W be enough for my room?

In our monitored installations about a third of the panels spent December–February with the room more than 1 °C below the set temperature. They were not faulty — they were fitted to rooms that lose more heat than one panel can replace on the coldest days, and they used more electricity than correctly sized panels while delivering less. Sizing guide for this panel:

• 10–14 m² as the only heat source — a modern or well-insulated room, one window.
• 7–9 m² as the only heat source — an older building with single glazing or an uninsulated wall.
• Up to 25 m² as supplementary heat — the room already has central heating and the panel adds comfort.
• Larger room? Add a 500 W white panel on another wall: 1 170 W across two surfaces, even warmth, roughly twice the warm-up speed. Two panels holding a room at 21 °C cost the same electricity as one panel would if it could — the room's heat loss sets the energy, not the number of panels.

Glass panel, oil radiator or a plain convector?

Every electric heater turns essentially all of its electricity into heat; for the same room at the same temperature the kWh are the same whatever you buy. What a controllable panel changes is when and where that energy is spent. Keeping an older heater for now? The Smart Thermostat plug gives it a room sensor, schedules and Nord Pool mode.

Technical specifications

• Power: 670 W rated; 200–350 W average in use. The thermostat cuts the heat once the room reaches the set temperature, so the average draw over a winter month is roughly half the rating.
• Size and weight: 1000 × 365 × 11 mm tempered white glass, 10 kg. Wall-mounted, vertical.
• Mounting: wall bracket included; free-standing with the optional stainless-steel legs.
• Control: Wi-Fi and Bluetooth (Bluetooth works up to 50 m without internet). Room thermostat, weekly schedule, timers, Nord Pool mode, consumption statistics and voice assistants — in the free GPO Home app, no subscription.
• Accurate room temperature: add the BLE temperature sensor to measure where you sit, not at the wall.
• Safety: fully insulated heating element, temperature-limited surface; does not scorch dust and does not dry the air.
• In the box: panel, wall bracket, device passport.
• Made in Estonia by GPO OÜ, Tallinn. CE marked, TÜV NORD certified for EMC and LVD.

FAQ

❓ How much will it add to my electricity bill?
As the only heat source in a correctly sized room: about €1.20 a day averaged over the season, ~€58 in February, roughly €255 for October–April at Estonian prices. As supplementary heat: about €0.39 a day. With a weekly schedule, around €85 less over the season.

❓ How do I know if one panel is enough?
As the only heat source, count on 10–14 m² in a well-insulated room and 7–9 m² in an older building. Above that, use it as supplementary heat or add a second panel. Send us the room size and building year and we will check.

❓ What if it does not reach the temperature I set?
Then the room loses more heat on cold days than one panel can replace. A 500 W panel on another wall fixes it — expect about €0.80 a day more in the cold months, and the temperature you actually asked for. Within 14 days you can also simply return the panel.

❓ Do I need an electrician?
No. Four screws for the wall bracket, then plug it into an ordinary socket. At 10 kg the panel needs a solid fixing; any standard wall anchor for that weight will do.

❓ Does it work if the internet goes down?
Yes. The schedule and the target temperature are stored in the panel; it keeps heating and syncs again when the connection returns.

❓ Can I use it in a bathroom?
Yes, outside the direct splash zone. For bathrooms we also make glass towel dryers that heat the room and dry towels at the same time.

❓ Which languages do the app and support work in?
The app is in Estonian, Latvian, Lithuanian, Finnish, Russian and English. Support answers in Estonian, Russian and English.

Consumption figures come from GPO's own device telemetry for the 2025/26 heating season, October to April, panels of the 670 W class reporting hourly; months with incomplete data and outliers excluded. Costs at 23.2 cents per delivered kWh — an Estonian household on a spot-price contract with the Võrk 2 network package, including network fees, charges, excise and 24 % VAT. Your consumption depends on your room, insulation and the temperature you choose.
