Heaters
Heaters keep home, office and site spaces workable when the temperature drops, from portable heaters for small rooms to gas heaters for bigger open areas.
When you're working through winter or trying to get some warmth into a cold room, the right heaters make a real difference. Electric heaters suit enclosed spaces and quick local heat, while gas heaters and larger space heaters are better where you need more output. If you're sorting site heaters, patio heaters or portable heaters, match the unit to the space and get the heat where it is actually needed.
What Are Heaters Used For?
- Warming up site cabins, workshops and work areas keeps lads productive on cold starts, especially when first thing in the morning the building has held no heat overnight.
- Heating a single room in a home or office with electric heaters is a straightforward way to add warmth without needing to run the whole property heating system harder than necessary.
- Drying out recently plastered walls, damp corners and decorated rooms is easier with space heaters when you need steady warmth moving through the area.
- Taking the edge off outdoor seating, smoking areas and covered work zones is where patio heaters and suitable portable heaters earn their keep.
- Supporting refurb and fit-out jobs in unheated buildings helps trades keep working when the shell is watertight but the main heating is not live yet.
Who Uses These Heaters?
- Builders and site managers use site heaters to keep temporary work areas usable during cold weather, especially on fit-out jobs, snagging and early starts in unfinished buildings.
- Decorators and plasterers reach for space heaters when they need controlled warmth to help coatings, filler and plaster dry properly without leaving the place freezing cold.
- Facilities teams and office managers use electric heaters for meeting rooms, reception areas and cold corners where the fixed system never seems to reach properly.
- Homeowners and landlords buy portable heaters for spare rooms, garages and short-term heating where fitting anything permanent would be overkill.
- Hospitality staff and outdoor venue teams rely on patio heaters to keep customers comfortable in covered outdoor areas once the temperature drops off.
Choosing the Right Heaters
Sorting the right heater is simple. Match it to the space, the ventilation and how quickly you need the heat.
1. Electric or Gas
If you are heating an enclosed home, office or finished room, electric heaters are usually the sensible choice because they are clean, straightforward and easy to place. If you are dealing with larger, draughtier or more open areas, gas heaters can make more sense for stronger heat output, but only where ventilation and safe use are properly covered.
2. Whole Room or Local Heat
If you only need to warm one desk area, small room or work bay, go for portable heaters or compact space heaters rather than overdoing it. If you are trying to lift the temperature across a bigger area, buy for output first or you will just end up with a heater running flat out and achieving very little.
3. Indoor, Covered or Open Air
Do not treat all heaters as interchangeable. Patio heaters are built for outdoor or covered external use, while many indoor electric heaters are meant for enclosed spaces only. If the area is open to the weather, pick something designed for that job rather than hoping a room heater will cope.
4. Portability and Positioning
If the heater needs to move around site, between rooms or from van to job, check the size and weight before anything else. Portable heaters are handy, but only if they are genuinely easy to carry, quick to set up and stable where they are going to be used.
The Basics: Understanding Heaters
The main thing to understand is not just how a heater makes heat, but where that heat is going and whether the space can actually hold it. Here is the simple version.
1. Electric Heaters for Enclosed Spaces
Electric heaters are the usual pick for homes, offices and finished indoor areas because they are easy to power and simple to control. They suit smaller rooms, local heat and steady background warmth where you do not want fumes, fuel bottles or extra setup.
2. Gas Heaters for Bigger or Draughtier Areas
Gas heaters are used where you need more heat output in spaces that lose warmth quickly, such as larger work areas or semi-open site conditions. They can shift a lot of heat, but they are not a casual indoor substitute and must be used with the right ventilation and safety in mind.
3. Portable and Patio Heaters for Position-Specific Heat
Portable heaters are about getting warmth exactly where the job is happening rather than trying to heat the whole building. Patio heaters do a similar job outdoors, giving focused heat to seating or covered external areas where standard room heaters would just waste energy.
Choose the Right Heaters for the Job
Use this quick guide to narrow down the right heater for the space.
| Your Job | Heater or Type | Key Features |
|---|---|---|
| Warming a bedroom, spare room or small office | Electric heater | Clean indoor use, simple controls, compact footprint and easy plug-in setup |
| Heating a cold workshop, garage or fit-out room | Space heater | Higher heat output, good room coverage and suitable for temporary heat where fixed heating is not on |
| Moving heat between rooms or around site | Portable heater | Carry-friendly design, quick setup and easy repositioning as the job moves on |
| Taking the chill off covered outdoor seating areas | Patio heater | Outdoor suitability, focused heat direction and stable placement for open-air use |
| Heating a larger draughty work area | Gas heater | Strong heat output for bigger spaces, but needs correct ventilation and safe positioning |
Common Buying and Usage Mistakes
- Buying too small a heater for a big, cold or draughty space means it will run constantly and still not warm the area properly. Check the room size and how much heat the building loses before choosing.
- Using an indoor heater in an outdoor or semi-open area wastes time and power because the heat just disappears. For exposed spots, use patio heaters or site-suitable units designed for that environment.
- Choosing gas heaters for enclosed areas without thinking about ventilation is a safety mistake, not just a buying one. Always match gas use to the correct setting and follow the operating guidance properly.
- Assuming portable heaters are all light and easy to move catches people out when the unit is bulkier than expected. If it needs to travel from van to room to site, check the actual size and handling first.
- Pointing a heater anywhere convenient rather than where the work is happening often gives poor results. Place it where warmth can circulate or hit the target area directly, not behind materials or in a dead corner.
Electric Heaters vs Gas Heaters vs Patio Heaters
Electric Heaters
Best for homes, offices and enclosed work areas where you want straightforward heat with no fuel handling. They are usually easier to place and control, but for very large or draughty spaces they can struggle if undersized.
Gas Heaters
Better suited to larger open work areas and tougher site conditions where more raw heat is needed. They are not the one for sealed rooms, and safe ventilation is part of the decision from the start.
Patio Heaters
Built for outdoor or covered external use where people need warmth in one fixed area rather than whole-room heating. They are useful for seating and sheltered outdoor spaces, but they are not a replacement for indoor room heaters.
Portable Heaters
Portable heaters are about flexibility more than one fuel type. They suit moving between jobs, rooms or work zones, but the right one still depends on whether the area is enclosed, open, small or draughty.
Maintenance and Care
Keep Vents Clear
Dust and fluff build up fast, especially in workshops, garages and site cabins. Keep air intakes and outlets clear so the heater can move air properly and not overwork itself.
Check Cables and Connections
Before each spell of use, check plugs, leads and any visible connections for damage. A heater with a crushed lead or loose plug wants sorting straight away, not patching up and hoping for the best.
Store It Dry and Upright
When the weather turns or the job is done, store heaters somewhere dry and stable. Leaving them in damp sheds or loose in the van shortens their life and can leave you with faults next time you need them.
Clean Before Long-Term Storage
Wipe down the casing and remove dust before putting the heater away for a few months. It stops muck baking on later and makes it easier to spot cracks, wear or loose parts before the next cold spell.
Replace Damaged Units Sensibly
If a heater has damaged guards, unstable feet, broken controls or heat issues, do not keep forcing it through another winter. Small cleaning and checks are one thing, but unsafe heating kit is worth replacing.

Heaters FAQs
What type of heater is best for home, office, or site use?
It depends on the space and how sealed it is. For homes and offices, electric heaters are usually the straightforward choice because they are clean, simple and suited to enclosed rooms. For site use, especially in larger or rougher areas, space heaters or gas heaters are often the better fit if you need more output.
Should I choose an electric heater or a gas heater?
If you are heating a room, office or finished indoor space, go electric in most cases. If you are dealing with a bigger, draughtier or more open work area and need stronger heat, a gas heater may be the better tool for the job. The key thing is ventilation and using the heater in the right environment, not just buying the hottest one.
Are portable heaters suitable for open or outdoor work areas?
Some are and some are not. Portable only means easy to move, not automatically suitable for outside use. For open or outdoor areas, you need a heater rated and designed for that setting, such as certain site heaters or patio heaters, otherwise the heat will be lost and the unit may not be safe for the job.
Can these heaters help speed up the drying of surfaces?
Yes, they can help when used properly. Trades often use heaters to support drying plaster, paint and damp rooms by lifting the room temperature and improving drying conditions. Just do not overdo it in one spot or blast heat at a surface without thinking about airflow and the finish you are trying to protect.
What size heater do I need for my space?
The bigger, colder and leakier the space, the more output you need. A small electric heater can be fine for a box room or office corner, but it will be hopeless in a large workshop or draughty unit. If you are between sizes, do not kid yourself with the smaller option just to save a few quid because it will work harder and do less.
Are patio heaters safe to use outdoors?
Yes, that is exactly what they are for, provided they are set up correctly and used as intended. Keep them stable, give them proper clearance and use them in suitable outdoor or covered outdoor areas. They are a better bet outside than trying to make an indoor heater do a job it was never built for.
Do you offer next-day delivery on heaters?
Yes. We stock heaters in our own warehouse, so if the item is showing in stock you can get it delivered quickly with next day delivery available. That matters when the cold weather lands and the job cannot wait.
Is finance available when buying heaters?
Yes, finance is available on qualifying orders. If you are buying more than one heater or sorting out a bigger setup for site, workshop or commercial use, it is worth checking the payment options available at checkout.
