Advantages of LPG for Home Generators

LPG powered home generators

It can be a challenge to decide between diesel, petrol and LPG (Liquid Petroleum Gas) powered HGI home generators. For that reason we have produced a simple way of deciding which type of generator is right for you. Our information pages focus on the advantages and disadvantages of each type of generator to help you decide what home generator would suit your needs.

An LPG powered home generator would be a great choice for a home requiring a steady, reliable source of back-up energy with convenience in mind.

The advantages of using an LPG generator.

Running Costs
Fuelling this style of generator would be a much cheaper option when compared to both petrol and diesel powered generators, with LPG costing around half the price of petrol.

LPG cylinders can be expected to last for a reasonable length of time. For example, with twin 19kg cylinders it is very possible to achieve standby running times of over 40 hours before refuelling would be required on a 14kW unit. There is also a variety of cylinder sizes available to match your needs.

The emissions of an LPG product are less harmful to the environment than the emissions from both petrol powered generators and diesel powered generators. LPG powered home generators release less carbon dioxide per unit of energy than petrol or diesel powered generators.

LPG cylinders for your LPG powered generator can easily be delivered to your door. The replacement of cylinders is also performed simply with the use of a changeover valve. Lpg does not deteriorate if stored for prolonged periods as petrol and diesel does.

The costs of maintaining an LPG powered generator is generally lower than that of a petrol powered generator. This is as a result of running more cleanly, not blocking the carburettor or hinder the function of the engine, leading to the spark plug and other components lasting longer than in a petrol fuelled engine.

Widespread Use
Due to the reduced emissions of LPG, they are able to be used in a wider range of places. Councils and campsites have been increasingly favouring the use of LPG powered generators, especially in public and areas of food preparation.

LPG powered home generators are known for running at a much quieter level than petrol powered engines.


Initial Cost
The conversion of a petrol powered generator to an LPG powered generator will usually add around £200-£500 to the cost of your start up. It is still more than likely, however, that this will be cheaper than your average diesel powered generator.

Power Options
The largest LPG powered home generators tend to be around 15KVA. Although this would be suitable for most applications, if your intensions require more power than this then a diesel powered generator will give you more power to work with.

As a result of LPG powered generators requiring the use of cylinders to contain the LPG, there are regulations regarding where these cylinders can be stored. These regulations include the stipulation of how far in proximity a cylinder must be to a window or drain.

As is the case with petrol, LPG is extremely flammable. For this reason it must be ensured that there is a gas tight seal between the valve of the cylinder and the regulator when you are changing cylinders. With the correct tools and training, however, this is simple to do – which will minimise the risk of fuel spillage, fire and injury.
