Calculate space volume (length × width × height in metres) and apply a rough rule of thumb of 0.05 kW per cubic metre for moderately insulated buildings, 0.075 kW per cubic metre for poorly insulated or draughty buildings, and 0.1 kW per cubic metre for outdoor, marquee, or open-front workshop applications. A typical 100 m² workshop with 4 m ceilings (400 m³) needs 20–30 kW for moderate insulation, 30–40 kW for poor insulation. Always size up rather than down — an oversized heater cycles to maintain temperature efficiently; an undersized one runs continuously without ever reaching working temperature.

Depends on the constraints. Propane (LPG) — clean-burning, portable, no fuel storage, but requires ventilation and gas-bottle exchange. Cost per kWh sits between electric and diesel. Diesel/paraffin — lowest fuel cost per kWh, high output, but produces combustion fumes and needs strong ventilation, best for larger or more open spaces. Electric fan heaters — cleanest, no fuel handling, no ventilation concern, but most expensive per kWh and limited by available electrical supply. Infrared — heats surfaces and people directly rather than air, very efficient for spot use and high-ceiling spaces, less effective for full-space heating.

Yes — all combustion heaters (propane, diesel, paraffin, kerosene) consume oxygen and produce combustion by-products including carbon monoxide. Indoor use requires adequate ventilation (typically two air changes per hour minimum) to maintain safe oxygen levels and prevent CO buildup. The heater specification lists the required minimum air change rate. Fully-sealed indoor spaces — workshops without open doors or ventilation grilles — should use only electric or infrared heating. CO alarms in workshops using combustion heaters are a sensible precaution.

Parts For Machines is an Authorised Distributor and Seller of SIP, Sealey, and Clarke across heating equipment. SIP covers a broad portable-heater range — propane, diesel, paraffin, kerosene, and electric fan heaters. Sealey covers similar breadth at mid-range trade pricing. Clarke covers entry-trade and mid-range portable heaters. Rhino covers the heavier industrial-grade propane and diesel space heaters for larger workshop and event use, particularly in the higher kW output bands.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa. Use the country selector at checkout to confirm coverage and delivery options for your destination.

Heating

Heating covers the industrial and workshop heaters that keep working environments productive through cold weather — propane heaters, electric fan heaters, infrared heaters, diesel and paraffin heaters, halogen heaters, and the larger space heaters used in workshops, garages, plant yards, agricultural buildings, and event venues. Parts For Machines supplies heating equipment for trade and industrial use, in portable, semi-portable, and wall-mounted formats. Within Heating you will find Propane Heater (LPG-fuelled space heaters and patio-style radiant heaters, typically 10–80 kW output for workshop and event use), Electric Fan Heater (mains-powered heaters for sealed indoor spaces — 110V site, 230V single-phase, or 400V three-phase across the range), Infrared Heater (radiant heat for spot-warming people and surfaces rather than air, popular in workshops with high ceilings or open doors), Diesel, Paraffin, and Kerosene Heaters (oil-fired space heaters with high output for large industrial spaces and outdoor workshop use), and Halogen Heater (compact electric radiant heaters for personal-area heating). Parts For Machines is an Authorised Distributor and Seller of SIP, Sealey, and Clarke across heating equipment. SIP covers a broad range — propane, diesel, paraffin, kerosene, and electric fan heaters across portable and semi-fixed installations. Sealey covers similar breadth with mid-range trade heaters. Clarke covers entry-trade and mid-range portable heaters. Rhino covers heavier-duty industrial heaters, particularly in the propane and diesel ranges suitable for marquee, large workshop, and construction-site use. Heater selection comes down to three factors: heat output (kW), space size and insulation level (which dictates the kW required to maintain working temperature), and fuel/power source (whether LPG, diesel/paraffin, or mains electric is available and economic). For unheated workshop spaces, plan around 0.05 kW per cubic metre as a starting calculation, more for poorly-insulated buildings or where high air-change rates are needed. Product pages list output (kW), fuel or power source, fuel consumption rate (litres/hour for liquid-fuel heaters), tank capacity (where applicable), thermostat type, and required ventilation. All combustion heaters require adequate ventilation; product specifications include the recommended air-change rate.
