floor heating ?

Post Posted: Mon Aug 06, 2007 4:34 pm

hello,
We are renovating an old house in the southwest Algarve (near Lagos- Bensafrim) and are doubting about floor heating. People are telling us different stories, some are very positive about floor heating because of the moist and cold season and some say it isn't necessary and very expensive.
Who can share his experience with us?

I looked at underfloor heating when we had our villa built (10 years ago now). At that time the only option was underfloor pipes with water heated from a gas boiler. Several friends here said that it was expensive to run (as gas is very expensive here) and that it is only sensible if you keep it switched on all the time (as the time to raise the temperature of the surrounding concrete is lengthy).

You can now heat water using solar panels. However, you need a lot of solar panels. There are some reports on this Forum about this approach but again it would be helpful for someone to quantify the cost to install (per 100 sq metres say) and to run.

Alternatively , nowadays you have the option of an electric blanket. From the advertisements this appears to be cheap to install and to run. However, this should be confirmed by someone who has had it installed.

If you live in the Algarve I suspect that underfloor heating is an expensive luxury (we don't really have cold weather). If you live further North then it may be viable.

Just a personal view that others may disagree with.

Hi had a new villa built and finished at end of 06 opted to go for underfloor heating and it was the only mistake we made with the villa.
We found it vrey expencive to run [two big gas bottles in five weeks] and a big hot water cylinder to run.Would have been better of with a combi boiler and rads.
Its works out cheaper to run the air con on heat than the under floor heating

Hi Freedom - you seem to confirm what I have always suspected. I still believe that here on the Algarve a good wood burning fire is more than adequate (with back up at the turn of the season from a/c units that provide heating in the evenings when the temperature drops). Cost is €405 per year for 3000kg of good quality oak that burns 24/7.

Anyone else had experience?

Thank you for your reactions.
The point is, that we do not live there permanentely and need something to keep the moist out. How about a demoistener? Something different than an Airco. Anyone with experience here?

It is my opinion that most of the moisture in a house is created by living in it, unless there are other structural defects involved.

Buy a couple of good dehumidifiers to run full time while you are there to remove the existing moisture and any from cooking, showering/bathing, open fires and breathing etc.

The climate here does promote high humidity but if the house is sealed when you leave then it should not be a problem. Never that easy though!
