Energy Efficient Home Heating

Kearney Property, Home Heating

We are all well aware that Ireland is consistently failing to achieve its carbon emission targets set by the EU.  Whilst major reform can only be brought about at Government level, we can all do our bit in our homes to reduce carbon emissions, reduce energy and help save our planet. 

More than 70% of the average household energy consumption is used by central heating systems.  The average homeowner spends €1,850 heating their home each year. 

But it’s November.  There’s a definite nip in the air and we need to heat our homes.  What are the most energy efficient options and what can we do to cut down on heating usage?

Quality insulation reduces the amount of heat needed to warm our homes.  There are three types of wall insulation: cavity wall insulation and, external wall insulation and internal dry lining. On average, a home loses between 20 – 30% of its heat through walls. You can save up to €600 per year on heating bills through properly insulating your walls.  Grants for insulation are available in many circumstances that range from €300 for attic insulation, to €6,000 for external wall insulation.

Heat pumps
Grants are also available for heat pump systems.  These are electrical devices which convert energy from the air outside into useful heat, in the same way a fridge extracts heat from its inside. In well-insulated houses they are very economical to run. They are an extremely efficient alternative to traditional oil, gas, solid fuel and electric home heating systems. Once the heat is within the pump, it is distributed within the home through radiators, underfloor heating or warm air units.

Heat Recovery Ventilation Systems
These systems are best for new or renovated buildings.  The HRV System recovers heat from the air that is evaporated from the hot water used in bathrooms and kitchens and then transfers this heat into fresh air that is ventilated into your home.

Electricity Supplier
Switching to a renewable energy electricity supplier will reduce your home’s carbon dioxide emissions. Before switching, compare tariffs to get one that works for you.

Zoned Heating
Ensure your heating system has the ability to heat particular zones of your home independently of each other, for example, downstairs only.  One switch to power the whole house is extremely wasteful. 

Biomass Boiler
Biomass boilers use wood chips, wood pellets or logs as their primary source of fuel.  They need more space to install since they are bigger than the average oil-fired boilers.  Also ensure you can source a fuel supplier before installing. 

Under-Floor Hot Water Pipes
Hot water pipes significantly reduce the household energy consumption when you install them under the floorboards. Much easier to do when building rather than altering afterwards. 

Radiator Panels
Radiator panels are among the most affordable energy efficiency measures that can be taken in a home.  They are also easy to install and require little maintenance. Radiator panels work by reflecting the heat produced by the radiators to ensure that the heat warms up the room instead of the walls.

The higher you set your heating appliance, the higher the household energy consumption levels. At 18⁰C, your house is warm and comfortable.  Set your radiator thermostat and the individual radiator valves to maintain this temperature. 

Rearrange your Furniture
The layout of your furniture may determine the heat absorption rates of your house. For instance, a couch positioned in front of a radiator absorbs the heat and so more heat is generated to warm the room.  Moving the sofa away from the heater helps heat circulate freely. You should position furniture pieces with dense fabric away from your central heating appliance.

Open curtains during the day to allow sunlight to enter the house.  The heat from the sun will help maintain warm temperatures.  Close them when it starts to get dark outside as they add an extra layer of insulation at night needed to maintain warmth.

Small changes will make a big difference.
