Specifying LPG from Calor

When mains gas isn't an option

Here's the next best thing

LPG is an alternative off-grid fuel that can be used in the same types of commercial and industrial space and water heating systems as natural gas, including radiator systems, warm-air heating, strip and plaque radiant heaters and industrial unit heaters. It’s equally suitable for use with condensing boilers.

The techniques employed for heat load and loss calculation are very similar to those for natural gas and there only minor additional or different requirements for the installation, ventilation and flueing of boilers or other appliances.

Legislation such as the government’s Clean Growth Strategy is driving further limits on the levels of noxious emissions that any energy-generating appliance can emit. LPG has the lowest carbon emissions of all fossil fuels with 11.7% less CO2 per kWh than heating oil - ensuring cleaner burning and cleaner air.1

...and for your customers

We understand the appearance of a new homes site is a prime consideration for your developer clients. Underground tanks are a discreet gas storage option that does not detract from a development’s aesthetics.
 LPG has the lowest carbon emissions of all fossil fuels with 11.7% less CO2 per kWh than heating oil.1 The figures look even better when you specify BioLPG, which can result in emissions-savings of up to 38% when compared to heating oil and support compliance with the Government’s Clean Growth strategy.2
On average, LPG boilers are £900 cheaper than buying a new replacement oil boiler.3 Plus, when switching from oil to LPG there is usually no need to change internal pipework or radiators. In addition, we keep ownership of the tank so there is no need to worry about tank replacement costs, which can be up to £2,000.4 
Typically, 60% of a business’s energy costs are for space heating and hot water so replacing an old oil boiler (quite possibly operating at 60% efficiency or lower) with a shiny new A-rated, high-efficiency condensing boiler will result in significantly lower energy bills for your clients.
