Stay warm in winter, save money & the planet

Image from To Vima –

Greece consumes more than double the amount of heating fuel used in Sweden and 3.5 times more energy than Finland in winter, due to 3.5 million Greek homes being poorly built, using outdated heating systems and lacking proper insulation.

The EU Environment report confirms that only 30 percent of Greek homes have minimal insulation and 15 percent double-glazed windows, earning Greece the title of “most wasteful” homes in the EU.

This explains why 70 percent of all domestic energy is used to power heating systems, with demand increasing steadily since 1990, which leaves Greece both dependent on other countries for constant supply and vulnerable to price increases.

With heating oil and electricity rates increasing steadily with austerity measures, how can residents of Greece stay warm without going broke?

If you’re a renter

There are measures you can take, even if you do not own your home.

In winter:

1. Choose a home carefully

The biggest determinant in whether you will be warm in winter and cool in summer is what house you choose to rent or buy. Some things to consider:
— Location: Apartments lower to the ground or sandwiched between two floors keep a more consistent temperature than those at the top.
— Look at the windows/doors: Are they a tight fit or are there gaps around the frame? Is there double-pane glass, and is it done right? Put your fingers near the seam and feel if there’s cold air seeping through. Not all double pane windows and doors are constructed properly and therefore do little or nothing to insulate against weather or sound.
— Look for insulation: Don’t take the word of the landlord regarding insulation. While you’re looking at the windows and doors, does the wall even appear thick enough for the possibility of insulation? If there isn’t considerable wall thickness where the sliding door pulls back when open, there’s no insulation. And ‘insulation’ to many Greeks means that pieces/sheets of plain white Styrofoam were stuffed in the wall, which does nothing. (See additional tips in the homeowner section).
— Choose an ‘autonomi’ heating system: Having an individual (autonomi) heating system means you can control the thermostat and pay only what you use, as opposed to being on the central (kentriki) system where someone else decides how long the heat is on/off and often has you paying equal or unfair portions of the petrol bill based on square meters.
— Natural gas: Some buildings/homes were built or renovated to use natural gas, rather than petrol (heating oil). Natural gas is far cheaper and very efficient, though I understand it’s not available in all areas of Greece. How much cheaper? Comparing apartments of the same size, I used to pay 50-150 euros for petrol in a former building in which it took forever for the heat to reach me, and I was always cold; now I pay between 7-25 euros for natural gas, heat is instantaneous, and I am always warm.

2. Weatherstrip, caulk and foam

Leaks account for up to 30 percent of energy escaping from the home. Taking the time to visit a hardware store and picking up a few winterizing supplies for under 20 euros can go a long way to keeping you warmer, saving money on your petrol/electricity bills and even insulate against noise. The biggest leaks can be found around the front door, windows and sliding doors

3. Door sweeps

A decent door sweep attached to a door with gap at the bottom can stop cold drafts from blowing in. Or use an old towel, flokati or door sock. You could make the latter with discarded materials, as shown in “How to make your own draft dodger.” I use these around certain windows, as well. Works just fine.

4. Cover windows/sliding doors

Curtains and drapes with or without insulation can be used to cover one-paned or otherwise hopeless doors and windows. It doesn’t solve the problem, but it helps create a low-to-medium barrier.

5. Avoid space heaters

It’s tempting to use space heaters when the central heating system leaves you cold, but they’re huge energy mongers that cause your electricity bill to skyrocket.

Year round:

6. Sign up for DEH off-peak rates

DEH/PPC offers reduced electricity rates during off-peak hours. See, “Save money with off-peak electricity rates for DEH” for details.

7. Use CFLs

Converting to compact fluorescent bulbs (CFLs) is one of the easiest and quickest solutions. Only 10 percent of the electricity pulsing through a normal bulb is being used for actual light, with 90 percent generating unnecessary heat. On the other hand, a 26-32 watt CFL has the equivalent brightness of a 100-watt bulb without carbon emissions or wasted energy.

A CFL will cost more initially, but pay for itself in one year, last 8 years and save 12 euros a year on the electricity bill per bulb. i.e. If you have 10 bulbs in the house, that’s 120 euros savings a year without having to replace them for 8 years. IKEA has them; Philips and Osram have them available at various supermarkets.

8. Stop the standby

Put your TV, stereo, DVD player and computer equipment on a power strip that you can power off at night instead of leaving on standby or sleep mode. Why? Because if there’s a light on, they’re still using electricity and you’re paying for it. (e.g. We saw a 20 percent drop in our electric bill by doing this one simple thing).

Same with your charger. The charger is still using electricity when plugged in; it doesn’t know you’ve disconnected your iPod or phone.

9. Turn down the temperature

When sleeping — Throw a down comforter or another blanket on the bed instead of letting the heat run at night. Some modern thermostats allow you to program it to come on a half hour before you wake up for work, so you’re not cold when getting ready or eating breakfast.

When washing — Lowering the temperature from 60°C to 40°C on the washer will save money/energy and still get clothes clean.

When cooling — Consider using 28°C and/or a standing/ceiling fan to circulate air, instead of 25°C.

When cooking — The last minutes of food preparation in the oven or on stove top don’t necessarily require full power, and the heat can be turned off. Plan meals so they can be baked at the same time or consecutively, rather than consuming extra energy to preheat for each dish.

10. Choose energy-efficient appliances

If your home came unfurnished, consider purchasing energy-saving appliances with the highest rating you can afford (‘A’ being the highest). It may appear expensive to pay an extra 100-200 euros for a higher rating, but it will quickly pay for itself, especially if it’s a refrigerator or stove (and you cook often).


If you’re a homeowner

In addition to the 10 tips above, homeowners have greater freedom and ability to save more by making long-term improvements.

1. Add insulation

Most homes in Greece are brick and cement based and don’t have insulation, even many newly built ones. Unless you personally oversaw the construction of your home, or had it inspected after purchasing it from a previous owner (who probably claimed it had insulation), it’s safe to assume there isn’t any.

How can you tell if your home has insulation?
a) If you hammer a nail into an outer wall to hang something and dust falls, the wall is solid or filled with plaster and has no insulation inside.
b) If you can’t hear the TV or stereo when a family member or roommate is using the shower or washing machine down the hall, there’s no insulation in the walls of your home. Insulation would deaden the sound.
c) If you put a hand up to an outer wall of your home on a cold day and can feel it’s cold, there is no barrier or insulation inside. The temperature should be neutral.
d) If the water coming into the house is ice cold in winter and hot in summer, and the toilet sweats after flushing, your pipes are not insulated.
e) If you can hear any noise from outside when all the doors and windows are shut, you have no insulation. You should hear nothing.

2. Upgrade heating system to natural gas

By getting away from a liquid gas and oil heating system and upgrading to natural gas, it will cost approximately 4,000 euros. But if you intend on owning this property for a long time, it will pay for itself quickly with a 25% to 40% savings annually on heating and electricity costs, plus a tax credit of up to 700 euros. Natural gas not only costs less, but also heats the home more quickly and efficiently so you will use less.

3. Put a water heater blanket on the water heater

Insulating the water heater helps water to warm up faster after flipping the switch (if it’s not already on a thermostat) and retain warmth.


4. Install a solar heater on the roof

Greece has plenty of sun, even on cold days. The best part: It can save up to 250 euros a year.

5. Replace old appliances

Major kitchen appliances that are older than 10-15 years old are less energy efficient than those made today and are the biggest energy wasters. New appliances have an initial cost, but quickly pay for themselves with up to a 20 percent savings per year.

Look for the Energy Star rating on new appliances when shopping. The highest rating is ‘A.’

6. Replace air filters

Replacing the air filters on air conditioning/heating units improves their efficiency

7. Upgrade to modern double-pane windows and doors

Replacing outdated, single-paned doors and/or windows would greatly improve energy efficiency by insulating against weather conditions and noise pollution. Even older double-glass doors and windows could stand updating since many are not air tight or fitted properly. (i.e. The house I once rented appeared to have double-pane glass, but the thickness, setting and fit are all done incorrectly, so cold air comes into the house and heat escapes).

If you’re stuck with a house that leaves you cold and none of these solutions are workable, I highly recommend: Silk thermal underwear (lightweight, breathable, efficient), 100% wool or cashmere sweaters, and Polartec jackets, hats and socks.


√ False – Putting rugs on the floor help keep the house warm. Rugs are purely a comfort item and do nothing to retain heat.

√ False – Natural gas is dangerous. Installation by inexperienced, unlicensed “technicians” are often the cause of accidents, not the gas itself since countries worldwide use it without incident.

√ False – CFLs have a weird glow. More modern technology has taken that glow away, creating a softer, more natural light without the inefficiency and emissions.

√ False – Putting the TV and stereo on a power strip will cause them to lose presets. If they’re already shut off, powering off via the strip while they’re on standby does nothing; it’s true that a DVD player may lose its place when powered off, however.

√ False – Wearing more layers equals more warmth. Keeping warm is about the fabrics you choose, not how many layers you put on. I can be toasty warm wearing one silk layer, one wool layer and one Polartec layer. The person next to me wearing seven cotton or acrylic layers will still be cold and look ridiculously bulky!

Aside: An EU directive that requires all newly built buildings in Greece to have a “green card” to certify its energy efficiency has not been implemented. Brussels set the deadline for January 4, 2009 and also provided guidelines on appliances, office equipment, water boilers, lighting and creating renewable energy, and Greece failed.

Ιt’ s very easy for anyone to save energy and protect our planet. It’s way of thinking. Good evening Kat

One query: surely, if you put rugs over the entire floor [like fitted carpet] it will keep the heat inside the room better? Carpets, like curtains, act as heat buffers through the air held in between the fibres: so, if your home loses heat through the floor, a lot of carpeting should make a difference…Admittedly, windows, doors and ceilings are usually the greater problem for heat loss.

All this talk of global warming has me confused and I just don’t get it.

What’s the problem with global warming anyways—I LOOK GREAT in SHORTS!!!

I live in a ground floor. Two entrances with metal doors which don’t seal and single pane glass. A good aluminum window with double pane glass. And an awful window with two pieces of glass without frame.

Problems: the temperature was like outside. And the ground is really cold.


Foam mania. I put foam in both doors to seal them. Also door sweeps. I locked one of the doors (because I don’t use it) and I put a really tight door sweep that seals better (but you cannot use it in that way if the door is working).

Side effects of the foam mania. The landlord fixed the main door lock after the foam mania day because it wasn´t closing good.

I put curtains for the main window and the locked door. The landlord installed a new outside blind for the good window. Also I put a cardboard piece in the locked door (Yesterday I threw it because it absorbed humidity and bent, now I have a huge double layer cardboard piece 😛 ).

For the awful window I put interior blinds. At least to stop sunlight and/or undesired looks inside my house.

I hope in summer the cold floor pays off, but now in winter, cheap carpets are doing a good job to avoid to wear two pair of socks and slippers. But a good temperature is difficult to maintain.

I use petrol heating, around 2 or 3 hours per day. usually in the afternoon during weekends and at dinner during the rest of the week. It also heats water so its perfect to have dinner, wash the dishes and then have a shower.

I still have problems with the door and the awful window. For the main door I guess a curtain will help (a thick one). And for the awful window perhaps another curtain and isolate the join of the two glasses better with… more foam.

I paid around 90 euros for the petrol during the last two months. Perhaps I should switch to electric heaters for off-peak hours: at night, tv, soft tea, you had your shower so a heater near the sofa can do “the job”.

Offtopic. I locked one of the doors, but of course I didn’t put a label “this door is locked and not used”. Therefore I receive a lot of delivery advertisement. Sometimes they put the flyers under the door and I receive them “directly in my bedroom” (that’s the reason I locked that door). And with the flyer also a lot of dust from outside because they open a bit the door sweep. I’m thinking on putting cement or something there 😀

V – Hello again! I believe that many people understand what to do, however I posted this because: a) I hear a lot of people whining about how cold it is; although I think if they ever lived or visited NYC, Chicago or Sweden, they would change their minds quickly; and b) not everyone knows what to do. According to this article, many admit they have no idea:

M – Your logic makes sense. However, because heat rises, it makes no difference what’s on the floor. It makes a greater difference that the house is sealed and there is insulation in the roof. Home builders/contractors in the USA confirmed the info I gave, and I’ve found it to be true in real life. i.e. I’ve lived in fully carpeted homes, been cold. I’ve lived in homes with linoleum and tile, not been cold. With many floors in GR being made of stone cold marble, it’s easy to understand how carpets could be perceived as being warmer. It’s cheaper to put on a pair of fleece socks. 😉

The S – True, a lot of people look great in shorts. But I think I’d rather see some rainfall, have bountiful crops & reasonable prices for produce, not see a repeat of wildfires and keep some polar bears around. I think polar bears look good in shorts too. 😉

G – MY! With all of your efforts and little result, it just sounds like your apartment has no insulation and unfortunately there is little that can be done about that. I personally miss the days when I could wear a T-shirt and shorts in the house; now we wear flannel and 300-weight Polar fleece, which I highly recommend. Some of the newer homes have insulation or better construction, but of course the rent is higher. In the end, it probably works out to be the same with what we pay in wasted petrol, electricity costs and discomfort. Cement…LOL! 😀

I’ve just asked my mother. She lives in a new (5 years old) house in Northern Spain. During Christmas you can enjoy 1 degree max and -6 min, (also a half frozen river).

Ok, are you ready? she pays up to 50 euros per month using natural gas for heating (She says “cuando hace mucho mucho frio”). And her house has the heating system under the floor. I pay 45 in petrol and I freeze.

She has the heating system almost always on, to 20 degrees. But you can walk without socks and you don’t get a red nose because the cold.

Of course the house is insulated for a cold area. Double pane and normal size windows and thick walls.

At least I hope the winter in Athens to be short.

Graf mou, I empathize with you.

In our last house, we had no insulation in the walls or roof, which was important because we were the top floor. We had to drag our bed into the living room in summer to take advantage of the air conditioner and the heaters (plural) in winter. It was demeaning, like we were poor college students and not adults with careers. It was never the right temp, I cooked in a 46C kitchen, and we were paying a lot (A LOT) of money for petrol and electricity — 800 euros petrol (which was our portion of 2400) and 650 euros electricity for 3 months. It would have been cheaper to rent a newer, more expensive apartment with proper construction. The temp was still warmer outside than inside in winter and cooler outside than inside in summer. That’s one of the major reasons we left. Not the only reason, but…

I lived in NYC with freezing temps, and I can’t remember ever being cold. At most, I paid 50 dollars per month for my apartment to be warm. In Sweden, the floors were heated and I paid 50 euros a month for the same square meters I have here.

For December and part of January, we have already paid 200 euros for petrol, and neither of us can say we’ve actually been warm without wearing layers of clothes/socks or being under a down comforter (also from Sweden; not IKEA). As in your case, the only solution is to move, but I’m not eager to get out the boxes again.

When I was India, the nice hotels we stayed in said the winter is so short that there is no need for insulation or hot water heaters. So of course, we had an invigorating time. 😉

Does anyone know where I can find building insulation (R-30) anywhere near Corinth, Greece. I have central air conditioning but do not have the proper attic insulation to keep the house cool in the summer. R-30 is not something you find very easily in Greece. Perhaps I just don’t know where to look.

Thanks for your feedback.

Kat Reply:

You’re right. R-30 or any type of insulation is difficult to find in Greece because Greeks (on the whole) believe that styrofoam sheets stuck into the wall are “insulation.” I do not know Corinth, but I’ll leave your question published in case another reader wants to answer.

In my experience over 15 years, things that are commonly found at everyday hardware or DIY home supply stores in other countries are considered specialty items in GR. For example, simple PVC is found at a plumbing and water supply store for builders and repairmen. Air conditioning items are found at stores selling, installing and providing maintenance for air conditioners or solar water heaters. Places like Praktiker or Leroy Merlin haven’t changed this trend.

Thank you for your question, and wishing you all the best.
