Footings & Foundations Phase 1 Winter 2017 29 Hybrid systems If you’re an environmentally conscious selfbuilder, it’s likely you’ll have explored the pros and cons of electric heat pumps, however you may have concerns about the reliability and the installation cost of such a system. A hybrid solution that combines a heat pump with LPG is a great option if you are nervous about choosing a system that relies solely on electricity. The electric heat pump provides warmth for the home on milder days, and the gas boiler, fuelled by LPG, offers a reliable secondary source of fuel to give you peace of mind on colder days whilst providing all your hot water. The system automatically selects the most cost-effective mode – using either the electric heat pump or LPG boiler – depending on the outside temperature and heat demand, in order to provide maximum efficiency. You simply input your energy tariff and the technology will deliver the lowest running cost, which could result in savings of up to 35 per cent on your gas bills, compared to a standard gas boiler. But it’s not just heating; LPG appliances can also help reduce your environmental impact. For example, LPG tumble dryers reduce energy consumption, as they use gas to heat the air inside the dryers – which means you only use 10 per cent of the total electricity used by a standard electric dryer. LPG tumble dryers are more energy efficient too with an energy rating of A, whereas regular electric dryers most commonly have an energy rating of C. This means overall they can be more than 40 per cent more energy-efficient. So, it’s clear to see that there is a wide range of greener and cleaner off-grid fuel options available, including LPG and BioLPG, that are not only kinder to the environment, but also highly efficient too. Calor is bringing BioLPG to market in early 2018. For more information on LPG or BioLPG for your rural self-build project, go to Calor.co.uk or call 0808 159 7864. www.calor.co.uk
