Benefits of Preheating

Benefits of Preheating

Protects the Engine
The moving parts in an engine, like bearings, crankshaft, connecting rods, camshaft, etc., wear out the most when they are cold. This wear is significantly reduced at higher temperatures. Therefore preheating your engine protects the engine from wear.

Increased Sustainability
As stated above, preheating your engine minimizes engine wear, which extends the service life of the engine. Preheating also has a positive effect on the life of liquids and batteries. Liquids age quicker at extreme temperatures or extreme temperature differences. Preheating results in a more stable temperature, which makes the liquids last longer. The charging capacity of a battery is also affected by extreme temperatures. When the battery is kept at a constant temperature the charging capacity remains intact longer.

Better for the Environment
Next to increased sustainability, preheating results in more environmental benefits. Most fuel is consumed when starting the engine and bringing the engine to operating temperature, and a cold engine emits more harmful substances compared to a warm engine. A preheated engine consumes less fuel and releases less emissions, making preheating beneficial for the environment.

Cost & Time Savings
A preheated engine is less sensitive to wear and therefore requires less maintenance, which results in lower maintenance costs. In addition, a warm engine consumes less fuel, which reduces your fuel costs. By preheating your engine you eliminate the engine warm-up time. You can immediately use the full engine power, without the risk of wear. This is essential for e.g. emergency power supplies, sprinkler systems, ambulances, rescue services, etc.
Coolant Heaters

Coolant Heaters

Coolant heaters warm up the engine by heating up the coolant and transferring the heat to the engine through the coolant. Some coolant heaters use a (electric) circulation pump to preheat the engine. These so-called forced flow heaters, or circulation heaters, warm up the coolant and pump it through the engine to provide even heat distribution.

Other coolant preheaters make use of the thermosiphon process for heat transfer. These heaters warm up the coolant and circulate it through the engine by thermal convection.
Fuel & Oil Heaters

Fuel & Oil Heaters

At low temperatures paraffin wax in diesel fuels can start gelling, causing the diesel to solidify and stop flowing. When the fuel can’t reach the engine, this of course causes serious problems.A similar effect can occur for oils. Low temperatures can increase the oils’ viscosity, which reduces the oil flow towards the engine and the hydraulic systems.The described problems can be prevented by making use of fuel and oil heaters. At GENHEAT we offer fuel and oil heaters from multiple brands.
Circulation & Tank Heaters

Circulation & Tank Heaters

Next to increased sustainability, preheating results in more environmental benefits. Most fuel is consumed when starting the engine and bringing the engine to operating temperature, and a cold engine emits more harmful substances compared to a warm engine. A preheated engine consumes less fuel and releases less emissions, making preheating beneficial for the environment.
PowerHeat Preheaters

PowerHeatis the new style (engine) pre-heater. The compact design, in combination with the chosen materials, integrated pump, adjustable thermostat and all required control and safety features, makes it an exceptional high quality heater.

The heat exchanger is based on a die-cast tubular component in aluminum with a large heating surface. The heating element is embedded in aluminum during the die-casting process so therefore completely corrosion proof and not in direct contact with the coolant or liquids. This means a more effective heating and no negative side effects for the coolant or liquids. In addition the Aluminum AS13 is finished with a Teflon coating.

The Calix fully automatic battery chargers make sure the battery of your vehicle or machine is always fully charged. The battery chargers are designed for both valve regulated (dry cell) and flooded (wet cell) lead acid batteries and deliver flawless performance, even in extreme temperatures (-40°C to +60°C). In addition, the Calix battery chargers can handle parallel loads, meaning they provide power to active users (e.g. lights and radio) while charging the battery.
Calix Insertion Heaters

Calix Insertion Heaters

Insertion heaters cannot be fitted to certain vehicles, e.g. some construction machinery, tractors, trucks, and in exceptional cases passenger cars. For these vehicles the Calix Professional Heater (PH) was developed. The PH works based on a self-circulating principle and is connected to the cooling system outside the engine block using a hose connection (20 mm). The heater is equipped with overheating protection, a thermostat, and a rubber sealing for increased service life and reliability. The heater can be delivered with only an installation bracket, or as a complete kit including the heater, cables, bracket, etc.

About us

GenHeat was established to address the increasing demand for specialised expertise and products in engine heating.

We provide heating solutions for diesel, fuel, coolant, engine oils, hydraulic oils, other industrial liquids, batteries, cabins, and more. Our systems enhance engine starting, reduce wear, lower fuel consumption, extend battery life, and minimise environmental impact.

An engine preheater warms the engine and maintains a stable starting temperature while it’s not in use. An engine heater can heat the engine's coolant and circulate it through the engine. This transfer of heat can occur in two ways: through a built-in circulation pump that moves the heated coolant, or via a thermosiphon or immersion heater that relies on natural convection to circulate the coolant.

Types of Preheaters Include:

Coolant Heaters

Coolant heaters warm the engine by heating the coolant and transferring that heat to the engine. Some use an electric circulation pump, known as forced flow or circulation heaters, to evenly distribute heat by pumping the coolant through the engine. Other coolant preheaters utilise the thermosiphon process, which relies on thermal convection to circulate the heated coolant through the engine.

Fuel & Oil Heaters
At low temperatures, paraffin wax in diesel fuel can begin to gel, leading to solidification and obstructed flow. This prevents the fuel from reaching the engine, causing significant issues. Oils can also experience increased viscosity in cold weather, reducing their flow to engines and hydraulic systems. These problems can be avoided with fuel and oil heaters, and at GENHEAT, we provide a range of heaters from various brands.

Circulation & Tank Heaters
In addition to enhancing sustainability, preheating offers significant environmental benefits. A substantial amount of fuel is used during engine start-up and reaching operating temperature, and a cold engine produces more harmful emissions than a warm one. Preheating reduces fuel consumption and lowers emissions, making it environmentally advantageous.

In addition to coolant heaters, we offer forced circulation heaters, thermosiphon heaters, and direct immersion heaters for warming (bio) fuels and (engine) oils.
