Winter Heating for Off-Grid Homes with Calor Ireland

30/10/2025 10 min

For rural households in Ireland and Northern Ireland, the colder winter months bring more than just frosty mornings. They often mean higher heating bills, draughty rooms in older houses, and the constant risk of power cuts that can disrupt daily life.

Many homes rely on oil or electricity for heating, but both come with challenges. Oil can be expensive and less efficient, while electric systems are costly to run and leave families vulnerable during outages.

That’s why more households are choosing Calor LPG and BioLPG - a reliable energy solution that delivers controllable warmth, fast hot water, and dependable cooking all winter long.

Why choose Calor for rural, off-grid heating?

Rural Ireland and Northern Ireland are home to a wide mix of property types, from farmhouses and cottages to hotels and guesthouses. Many of these buildings share common heating challenges:

Calor addresses these challenges directly:

  • Controllable home heating: LPG provides instant warmth, instant hot water and controllable cooking
  • Cleaner combustion: LPG emits fewer particulates compared with oil or solid fuel.
  • BioLPG: A renewable, drop-in alternative to LPG that lowers carbon emissions by up to 80%* while working seamlessly in existing LPG boilers.
  • Versatility across property types: Whether it’s a new build, farmhouse, cottage, vernacular home, detached house, small hotel, or rural Airbnb, LPG and BioLPG offer flexible, efficient energy.

Switching from oil or electric to LPG or BioLPG

Many homes across Ireland and Northern Ireland still rely on oil or electricity for heating. While both have served households for decades, they come with clear drawbacks. Oil boilers can be costly to run, less efficient, and carry the risk of leaks or spills. Electric heating, meanwhile, is expensive and unreliable during winter storms, when power lines go down, so does the heat and hot water.

That’s why more households are making the move to Calor LPG and BioLPG. The benefits are immediate:

  • Switch from oil to LPG and you can look forward to cleaner combustion, fewer emissions, and no risk of oil spills.
  • Switch from electricity to LPG and enjoy faster, controllable heating and hot water compared to electric systems.
  • Switching to BioLPG and benefit from a renewable alternative that cuts carbon emissions by up to 80%*! Plus, BioLPG works in any existing LPG system with no modifications.

Best of all, switching to Calor LPG or BioLPG is easy and our dedicated customer care team is here to assist you every step of the way.

Winter-proof your tank & deliveries

For rural households, a reliable fuel supply is essential in winter. Heavy snow, flooding, or blocked roads can delay deliveries, so it pays to prepare both your tank and your delivery plan before bad weather sets in.

Keep your tank winter-ready:

  • Check levels early → Don’t wait until the first cold snap. Make sure your tank is at a healthy level going into storm season.
  • Keep access clear → Snow, ice, or fallen branches can block delivery routes. Clearing the path to your tank ensures drivers can refill it safely.
  • Protect fittings → Regularly check that valves, lids, and gauges are secure and free from ice or debris.

Homes in the Republic of Ireland and Northern Ireland can choose between the following bulk tank refuel options:

  • Top-Up → Calor remotely monitors your usage and automatically refills your tank, ensuring you’ll never run out unexpectedly, a popular choice for households in exposed rural areas.
  • Order-Only → You manage your usage and place an order once your tank gauge reaches 30%. This gives you more control over scheduling.

Fabric-first upgrades for rural homes

Heating fuel is only part of the winter comfort equation. Many rural homes in Ireland, from farmhouses to cottages were built before modern building standards, which means they lose heat much faster than newer properties. Improving the “fabric” of your home (the walls, roof, windows, and floors) ensures that the energy you pay for stays inside, reducing bills and improving comfort.

Practical, cost-effective upgrades include:

  • Draught-proofing: Unsealed gaps around doors, windows, and chimneys can let in cold air and drive up heating demand. A weekend’s work with draught excluders, sealant, or chimney balloons can significantly cut heat loss.
  • Attic insulation: Irish homes lose approx 20-30% of its heat through the roof. Adding or topping up attic insulation is one of the best-value measures you can take, with payback often in just a few years.
  • Cylinder and pipe lagging: Insulating hot water cylinders and exposed pipes reduces wasted heat and keeps water warmer for longer.
  • Radiator optimisation: Bleeding radiators to remove trapped air, installing thermostatic radiator valves, and ensuring radiators aren’t blocked by furniture all improve heating efficiency.

These “fabric-first” improvements, combined with an efficient LPG or BioLPG heating system, mean rural households can stay warmer for less - a win for both comfort and long-term savings.

Hot water efficiency on LPG

Hot water is a year-round necessity, but in winter it becomes even more important for comfort and hygiene. With Calor LPG, households benefit from a system that is not only reliable but also highly efficient.

  • Instant heating – Modern LPG combi boilers provide hot water on demand, so you’re not paying to keep a tank heated all day. This reduces wasted energy and helps lower bills.
  • Reliable supply – Unlike electric immersion heaters, LPG boilers don’t depend on the grid. Even during power cuts, you’ll have hot water for showers, cooking, and cleaning.
  • Faster recovery times – LPG systems reheat water more quickly than oil boilers, meaning no waiting around for the cylinder to refill after back-to-back showers or baths.
  • Everyday family comfort – A steady flow of hot water makes daily routines smoother, from busy mornings with multiple showers to evening cooking and laundry.
  • Sustainable option with BioLPG – By choosing BioLPG, you can enjoy the same reliable supply while cutting carbon emissions by up to 80%*.

Rural resilience & safety

Winter storms and power cuts are an unavoidable reality for many rural households in Ireland and Northern Ireland. Being prepared means more than just staying warm.it’s about ensuring safety, access, and peace of mind.

  • Heating continuity when it matters most: With Calor LPG and BioLPG, boilers and hot water systems keep running even if the electricity goes out. This ensures families aren’t left without essential heat or hot water during outages.
  • Cooking without interruption: Gas hobs and ovens continue to work during power cuts, allowing households to prepare hot meals when shops may be closed, deliveries delayed, or electricity unavailable.
  • Safe tank management: Before winter, check that your tank is topped up and that the area around it is safe and accessible. Keep paths clear of snow, ice, or overgrown branches so Calor’s delivery drivers can reach it safely.
  • Emergency readiness: Store a simple winter kit: torches, extra batteries, blankets, a first-aid kit, and a battery-powered radio. Having these on hand reduces risk and makes it easier to manage through extended outages or blocked roads.

Home Energy Savings Tips

Winter preparation checklist for warmer homes in Ireland & NI

A little preparation goes a long way in keeping rural, off-grid homes safe, warm, and efficient through winter. Here are ten practical steps to prepare your home for winter:

  1. Check LPG tank levels early: Top up before the cold sets in. With Calor’s Top-Up service, you’ll never run out unexpectedly.
  2. Book a boiler service: Annual checks keep your system running efficiently and reduce the risk of breakdowns during a cold snap.
  3. Draught-proof doors and windows : Simple seals and excluders stop heat escaping and cut bills.
  4. Upgrade attic insulation: Between 20-30% of home heat can be lost through the roof; insulation is one of the best-value upgrades.
  5. Lag hot water pipes and cylinder: Insulation keeps water warmer for longer and reduces wasted energy.
  6. Optimise radiators: Bleed radiators and use thermostatic valves to spread heat evenly and avoid cold spots.
  7. Clear gutters and secure outdoor items: Prevent leaks and damage from blocked drains, loose bins, or garden furniture.
  8. Prepare an emergency kit: Stock torches, spare batteries, blankets, bottled water, non-perishable food, and a battery-powered radio.
  9. Keep delivery access clear:  Remove snow, ice, or overhanging branches so your LPG deliveries can arrive safely.
  10. Keep an easy-to-find emergency contact list: Include numbers such as:
