Central heating systems are rarely powerful enough to get sufficient warmth to the bathroom. Even if your central heater is indeed powerful, the radiators are often positioned to direct most warmth into the living areas such as the sitting room, dining area, bedrooms, and perhaps the kitchen.
This often leaves the bathroom a little colder than the other rooms, which, in a way, is not too bad considering that you spend very little time in the bathroom.
However, the challenge is that you’ll likely need supplemental heat in the bathroom whenever someone’s in there as the bathroom tends to get quite chilly, especially early in the morning when most people take a shower.
That’s where a bathroom wall heater comes in handy! This guide should help you pick out the best bathroom wall heater.
Why Use an Additional Heater?
Supplemental heating in the bathroom is essential for two reasons. First, the central heating system might not pump enough heat into the bathroom. This can often leave the bathroom chillier than other areas in the home. A supplemental heating source can remedy this problem.
Secondly, the bathroom is one of the coldest places in the home, perhaps because it’s also the least insulated room. In the winter, these rooms can feel particularly cold. Supplemental heating helps keep the area cozier, allowing you to enjoy your baths and showers more.
Types of Wall-Mounted Bathroom Heaters
There are four main bathroom wall heater options to choose from, i.e., oil heaters, mobile radiating panels, fan heaters, and halogen heaters.
- Oil heaters: Oil heaters are electric heaters. The purpose of the oil is to absorb the heat from the electrical resistor wire and release it as gentle radiant heat. The oil also helps to conserve the heat, releasing it slowly and more efficiently.
- Mobile radiating panels: These, too, are radiant heaters. They emit heat as infrared radiation. But, they don’t have any oil. Instead, the heat comes off a flat panel. It’s worth mentioning that radiant panels also emit small amounts of convective heat.
- Fan heaters: Fan heaters are convective heaters, but feature in-built or complementary fans to help blow the heat throughout the intended space. In larger bathrooms, an oscillating fan is used to send the heat in all directions.
- Halogen heaters: Halogen heaters consist of a heating element protected by a grille. The heating elements contain a filament and halogen gas. The filament is heated using electric current, producing strong heat waves. The halogen helps to get the heat around in gentle, infrared radiation.
Factors to Consider When Choosing a Best Electric Wall Heater for Bathroom
Bathroom wall heaters come in endless styles and designs. The following are a few key factors to consider when shopping.
Heating Capacity (Watts/BTU)
Heating capacity, given in watts for electric heaters and BTU for gas heaters, refers to the heat you can get from the heating unit. For the average bathroom, you need about 1,000 watts or 3,410 BTU. However, most bathroom heaters are rated at 1,500 watts or higher.
Cost of Heating
The cost of heating will depend on several factors, including the type of heater chosen, heating method (electricity or gas (propane/natural gas)), the size of the heater, and the heater’s efficiency. Infrared heaters cost more upfront but are some of the cheapest to run.
Extra features refer to timers, thermostats, heat settings, and remote control, increasing the user’s convenience. Other extras to consider are Wi-Fi control, smartphone app control, and smart-home integration.
For the bathroom, you may want to choose a beautiful heater that adds some style to the room. Therefore, the color of the unit, design style, finish material, and lighting (if any) are welcome considerations. Size and low-noise levels are other factors to keep in mind.
Finally, it’s also essential to buy a safe heater. So, check for safety features such as overheating protection. Make sure that the heater is certified by a recognized standards agency such as Intertek, ETL, or CSA.
Safety Tips When Using a Bathroom Heaters Wall Mounted
Even after verifying that you’re buying a safe heater, certified by a recognized standards agency, you must use the unit with caution for complete safety. Observing the following safety tips would be a good start.
- Never use just any space heater for the bathroom. That’s because bathroom heaters are specially designed to resist the bathroom’s high humidity and damp conditions. Other space heaters may not be so resistant to water spills and bathroom moisture.
- Always read, understand, and abide by the manufacturer’s instructions and guidelines. It both keeps you safer and helps you maintain your warranty.
- Install the heater as directed by the manufacturer, observing the recommended height, clearance, and other spacing requirements.
- Waterproof heaters can still get wet. Just because the box says “waterproof” doesn’t mean you should cover it in water. A “waterproof” electric heater can still cause electric shocks when exposed to too much water.
- Never obstruct the heater in any way. A few people, for instance, have turned the wall heaters in their bathrooms into towel holders. Others also feel they can use the heater to dry wet garments. Don’t. It creates an unnecessary safety risk.
- Plug the heater into a wall socket and tuck away any cords. Extension cords create a tripping hazard. Moreover, most extension cords have a low current rating, thus create an overheating and fire risk. If there are any cords left after the installation, tuck them away.
Above all, always keep a fire extinguisher close. You may never have to use it. But, it’s better to be safe than sorry.
