Clarke CHT1000
Best OverallPros
- Powerful 10kW output for large spaces
- Rugged steel casing
- Adjustable thermostat
Cons
- Heavy at 14.5 kg
- Requires 16A supply
The Clarke CHT1000 is the standout model in the Clarke garage heater range, delivering 10kW of heat output that can warm a typical two-car garage quickly. Owner reviews consistently praise its build quality, noting the robust steel casing that withstands workshop knocks. The adjustable thermostat allows precise temperature control, making it suitable for both working and storage spaces.
This model requires a 16A power supply, which may need an electrician to install a dedicated circuit. Once set up, it provides consistent, fan-forced heat with minimal noise. For those needing a reliable primary heater for a medium to large garage, the CHT1000 offers the best balance of power and value.
Clarke CHT500
Best BudgetPros
- Compact and portable
- Plugs into standard 13A socket
- Quiet operation
Cons
- Only suitable for small spaces
- No thermostat
The Clarke CHT500 is the entry-level option, offering 5kW of heat output that is ideal for small garages or single-car workshops. Its compact design and lighter weight make it easy to move around, and it runs on a standard 13A plug, so no special wiring is needed. Owner feedback highlights its quiet fan and reliable performance for occasional use.
This model lacks an adjustable thermostat, meaning it runs at full power until switched off. It is best suited for quick warm-ups or as a supplementary heater. For budget-conscious buyers with a small space, the CHT500 delivers dependable warmth without breaking the bank.
Clarke CHT2000
Large WorkshopsPros
- High 20kW output for large areas
- Adjustable thermostat and fan speed
- Durable construction
Cons
- Very heavy and bulky
- Requires professional installation
The Clarke CHT2000 steps up the power to 20kW, making it suitable for large workshops or commercial garages. It features an adjustable thermostat and multiple fan speeds, giving users control over heat distribution. Owner reviews note that it heats up quickly and maintains temperature well, even in draughty spaces.
This unit is heavy and requires a dedicated 32A supply, so installation is not a DIY job. It is best for those with a permanent heating need in a large area. The CHT2000 is a workhorse that delivers consistent performance for demanding environments.
Clarke CHT3000
Heavy DutyPros
- Extremely powerful 30kW output
- Industrial-grade build
- Thermostat and overheat protection
Cons
- Very expensive
- Requires 3-phase power supply
The Clarke CHT3000 is the most powerful model in the range, with 30kW of heat output designed for industrial or very large commercial garages. It features robust safety systems including overheat protection and a thermostat. Owner reviews from commercial users praise its ability to heat vast spaces quickly and maintain temperature.
This unit requires a 3-phase electrical supply, limiting its use to facilities with that infrastructure. It is also the heaviest and most expensive option. For those with the right setup, the CHT3000 provides unmatched heating performance.
Clarke CHT1500
Medium GaragesPros
- Good power for medium spaces
- Adjustable thermostat
- Reliable Clarke build
Cons
- Heavier than CHT1000
- Requires 32A supply
The Clarke CHT1500 sits between the CHT1000 and CHT2000, offering 15kW of heat for medium-sized garages or workshops. It includes an adjustable thermostat for temperature control and has a solid build quality typical of Clarke products. Owner reviews mention it heats evenly and is quieter than expected for its power level.
This model requires a 32A supply, similar to the CHT2000, which may need professional installation. It is a good middle-ground option for those who find the CHT1000 too small but do not need the full 20kW of the CHT2000. However, the price difference often makes the CHT2000 better value for a small extra investment.
What to check before buying a Clarke garage heater
Before purchasing a Clarke garage heater, consider the size of your space. A 5kW unit is sufficient for a single-car garage, while a 10kW or higher model is needed for larger workshops. Check your electrical supply; some models require a 16A or 32A circuit, while others run on a standard 13A plug. Also, think about portability versus permanent installation. Heavier units like the CHT2000 are best fixed in place, while the CHT500 can be moved easily.
Mistakes to avoid
A common mistake is underestimating the power needed for a garage. An underpowered heater will run constantly without warming the space, wasting energy. Another error is ignoring electrical requirements. Buying a unit that needs a 32A supply when you only have a 13A socket can lead to costly installation fees. Always measure your garage volume and check your electrical panel before buying.
