There are currently 3.6 million households that are not connected to the mains gas network in the UK. This number keeps steadily rising due to new builds in rural areas.Pressure for new, affordable housing has councils peering over the fence into unspoilt green belt land with no current energy sources.It begs the question for builders, architects, landlords, tenants and homeowners, which energy source they would choose?This article looks at the advantages of using LPG (Liquid Petroleum Gas) over using heating oil, renewables or electricity.At a time when environmental impact is seemingly at the forefront of everyone’s agenda, LPG has less emissions of harmful Co2 and sulphur gasses meaning it is a cleaner source of fuel than that of oil.We know that LPG is much more versatile than its competitors, giving us central heating, hot water, fireplaces and cooking. We also know that per unit, LPG is highly efficient, but let’s consider why else it has the slight edge over its alternatives.Builders working on new builds now work to much stricter rules around the energy saving legislation, meaning that new building regulations consider environmental impact as a serious priority. Builders also work closely with health & safety regulations when installing energy sources. Always check that your builder is working within the rules and regulations of energy source installations, as making changes at a later date to tank location will be very costly and sometimes impossible due to the location rules.When choosing between Heating oil and LPG, we must take into consideration the actual tank. A heating oil tank can easily cost £1000 before installation costs. An LPG tank however, is on an annual rental basis from the LPG provider and also installed by the provider.We then consider the running costs of fuel; using electricity for heating and cooking is expensive, heating oil is limited to only heating unless the occupier has an Aga style cooker and is slightly more expensive than LPG. The new kid on the block ‘renewable energy’ is being met by a mixed reception as it is considered by many as unreliable due to fluctuation in the weather. Although renewable energy sources are free, they can often come with a hefty installation bill prolonging any financial benefit to the consumer. If you can cut through the reams of planning permission red tape, and install renewable energy equipment, you must then also plan for a secondary, more reliable back up source creating a ‘hybrid system’.
