Clarke vs Draper Garage Heater

Clarke vs Draper Garage Heater: Which One Should You Choose?

When it comes to heating a garage or workshop, Clarke and Draper are two well-known British brands that offer reliable propane heaters. The Clarke CHT900 and Draper DHG20 are their most popular models, but they cater to different needs. This comparison will help you decide based on heat output, safety, build quality, and value.

Clarke CHT900 Overview

The Clarke CHT900 is a heavy-duty propane heater designed for larger spaces. With a 9 kW output, it can heat up to 300 square feet, making it ideal for double garages or workshops. It features a robust steel body and three safety mechanisms: flame failure, tip-over shut-off, and an oxygen depletion sensor. Owner reviews from retailers like Screwfix and Amazon highlight its consistent performance and durability. Many users note that it heats a cold garage quickly, even in winter. The unit weighs 12.5 kg, which is heavier than the Draper, but this adds to its stability. Clarke backs it with a 2-year warranty, reflecting confidence in its build.

Draper DHG20 Overview

The Draper DHG20 is a lighter, more portable propane heater with a 6.5 kW output, suitable for single garages or smaller workshops up to 200 square feet. It includes flame failure and tip-over safety features, but lacks the oxygen depletion sensor found on the Clarke. Owner reviews praise its ease of use and quick setup, though some mention it struggles in very cold conditions for larger spaces. At 8.5 kg, it is easy to move around. The Draper comes with a 1-year warranty, which is standard for its price bracket. It is a solid choice for those on a budget who need basic, reliable heating.

Heat Output and Coverage

The Clarke CHT900 delivers 9 kW (30,700 BTU) of heat, covering up to 300 square feet. This makes it suitable for double garages, workshops, or even small commercial spaces. The Draper DHG20 offers 6.5 kW (22,200 BTU), covering up to 200 square feet. For a typical single-car garage, the Draper is sufficient, but for larger areas, the Clarke is the better choice. If you need to heat a space quickly, the Clarke's higher output means faster warm-up times.

Safety Features

Safety is critical for propane heaters. The Clarke CHT900 includes three safety features: a flame failure device that cuts gas if the flame goes out, a tip-over switch that shuts it down if knocked over, and an oxygen depletion sensor (ODS) that stops operation if oxygen levels drop. The Draper DHG20 has flame failure and tip-over protection but lacks the ODS. For enclosed garages, the Clarke's ODS provides an extra layer of safety, especially if ventilation is limited. Owner reviews on both models report no major safety issues, but the Clarke is considered more robust in this area.

Build Quality and Portability

The Clarke CHT900 is built with a heavy-gauge steel casing, giving it a solid, industrial feel. It weighs 12.5 kg, which makes it less portable but more stable during operation. The Draper DHG20 uses lighter materials and weighs 8.5 kg, making it easier to move between locations. Both have handles for carrying, but the Draper is more suited for users who need to store or transport the heater frequently. Long-term owner reviews suggest the Clarke holds up better over years of use, with fewer reports of rust or component failure.

What to Check Before Buying a Garage Heater

Before purchasing, consider the size of your garage. Measure the square footage and match it to the heater's coverage. Ensure you have proper ventilation for propane heaters, as they consume oxygen. Check the safety features, especially if the heater will be used in an enclosed space. Also, consider the weight and portability if you plan to move it. Finally, look at the warranty length, as it often indicates build quality.

Mistakes to Avoid

A common mistake is buying a heater that is too small for the space, leading to inadequate heating. Another is ignoring ventilation requirements, which can be a safety hazard. Some users overlook the importance of an oxygen depletion sensor for enclosed garages. Also, avoid placing the heater near flammable materials or in high-traffic areas where it could be knocked over. Finally, do not skip reading owner reviews to check for common issues like noise or reliability.

Price and Value

The Clarke CHT900 is priced higher than the Draper DHG20, reflecting its larger output, better safety features, and longer warranty. The Draper offers good value for smaller garages and tighter budgets. Both are available from major retailers like Amazon and Screwfix. For the extra cost, the Clarke provides better long-term value for larger spaces, while the Draper is a cost-effective solution for occasional use in small areas.
