Our most common FAQs
How does a dehumidifier work?
A dehumidifier removes excess moisture from the air, reducing dampness and improving air quality to create a healthier, more comfortable home environment for your family.
What size dehumidifier do I need for my space?
Choose a dehumidifier based on your room size - small units for bedrooms and offices, larger ones for living rooms or damp areas. Our guides help you pick the right size easily.
How much does it cost to run a dehumidifier?
Our energy-efficient models typically cost just a few pence per hour to run, helping you save on bills while keeping your home dry and comfortable.
Are fans energy efficient to run?
Fans are generally considered more energy-efficient than air conditioners and can be a cost-effective way to cool your space. As mentioned before, DC fans are known for their high energy efficiency compared to traditional AC fans. They consume less power while still providing powerful airflow.
What features should I look for in a fan?
Devola fans come packed with features designed to meet your needs. Choose your preferred airflow settings and take advantage of adjustable speed options. You might also appreciate additional features like remote control functionality, oscillation modes, and convenient timer settings for added flexibility.
What is an extractor fan and what does it do?
An extractor fan helps remove excess moisture, steam, and odours from the air - especially important in UK homes where wet weather and indoor laundry drying are common. It helps prevent condensation, damp and mould, keeping your home fresher, healthier, and easier to maintain.
How do I choose the right size or extraction rate?
Choose based on your room size and how much steam or moisture is produced. A bathroom with daily showers or a utility room used for drying laundry will need a higher extraction rate than a guest toilet. Our product guides make it easy to find the right match.
Can I install an extractor fan myself?
If you're confident with DIY, some Devola fan kits can be fitted by a capable homeowner. However, for safety and compliance - especially with wired models or those installed in bathrooms - we recommend using a qualified electrician.
Do extractor fans use a lot of electricity?
No - Devola extractor fans are highly energy efficient. Even with regular use during showers, cooking or damp days, they cost just pennies to run and help prevent the far greater cost of dealing with damp or mould damage later on.
What size patio heater do I need for my outdoor space?
When choosing a patio heater, consider the size of your outdoor space - larger areas need more powerful heaters. Also, think about your climate - colder areas may require a bigger heater than milder ones. Most Devola patio heaters cover between 12-22 square meters of outside space.
Are patio heaters safe to use?
Patio heaters are generally safe to use, but it is important to take precautions when operating them. Always follow the manufacturer's instructions and make sure the heater is placed on a level and stable surface. Keep children and pets away from the heater and never leave it unattended while in use.
Do panel heaters make noise?
Devola panel heaters typically do not make much noise, if any at all. They are designed to operate silently, making them a great choice for use in bedrooms or other quiet spaces.
Can panel heaters be wall-mounted and freestanding?
Devola heaters include both fixings and feet, giving you the flexibility to either mount them permanently on the wall or move them wherever you need warmth.
What size oil-filled radiator do I need for my room?
The right size depends on your room’s dimensions and insulation. As a general guide, you’ll need around 100 watts of heating power per square metre. A 1500W radiator is ideal for medium-sized rooms, while larger rooms may require a 2000W or higher model.
Do oil-filled radiators take long to heat up?
Oil-filled radiators take slightly longer to warm up compared to fan heaters, but once they do, they provide steady, long-lasting heat. The retained warmth in the oil means your room stays comfortable for longer without constant power usage.
Do I need to vent my portable air conditioner out a window?
Yes, it is important to vent the warm air from a portable air conditioner out of a window using an exhaust hose. This allows for proper air circulation and cooling efficiency.
What size portable air conditioner do I need for my room?
The size of a portable air conditioner depends on the room's size. Generally, a unit with 8,000 to 10,000 BTUs (British Thermal Units) is ideal for rooms up to 300 square feet.
