Re: floor heating ?

Sorry Nimitza - I can't agree with you. We live here all the time. We have no problems with moisture or condensation or humidity. However, having owned property here for over 20 years I know that if a place is not occupied then you do get problems with humidity if there is no heating. So all our wardrobes have wafer heaters installed. When we went to Australia for a 3 month holiday a few years ago we left them switched on. As a result we had no condensation or moisture problems and no mildew on clothes. I know from previous experience that without adequate heating (albeit very low) there is a real risk of moisture from condensation.

To be honest, I also believe that installing air flow and not sealing the villa is very beneficial. Even in the UK I had air flow through the loft as I suffered from damp in the roof and when I had an Inspector (Surveyor) round, as I made an insurance claim, he told me that there was inadequate ventilation. So we have air flow in virtually all our rooms in our current villa and even in the sealed roof void to ensure that there is adequate ventilation. As I said earlier, as a result, we have absolutely no problem with condensation, moisture or mildew.

we have a combi with radiators in all rooms and also provides hot water on demand

its a short winter so we dont use a lot of bottle gas per annum.

note it gets cold in dec jan feb so its nice to be snug and warm in the evenings before bedtime,

and why not spoil yourselves and install a nice log stove .

the builders here tend to hide all the polthene plumbing pipes under the floor then tile over them , we have found our bathroom floor gets really warm as the pipe work from the boiler to the main rooms run under the bathroom

Hi Rod,

Just my experience to date.
We live in a row of 10 new builds. Only half or less are occupied full time. The people that only visit for holidays have not mentioned any problems with mildew or the likes. Mind you, they probably leave no clothes in the house.
We are living here. We did not notice a problem until we had guests to stay last October, a very wet month, plus the extra showering and cooking etc.
We then proceeded to buy a dehumidifier.
Although a new build, there is only a little ventilation incorporated in the house. The shower and cooker extractor fans plus air inlet to these areas.
Bedrooms and lounge have none.
Summer seems fine and we have not had the dehumidifier on since May.
The problem may be due to the fact that we do not employ any heating apart from our log burner.
I am sure that it is a common problem over here.

The system for laying pipes here in Portugal for plumbing is called Wirsbo. It relies on installing ducting under the floor (corrugated blue and red pipes) and then pulling the water pipes through and terminating in a number of manifolds placed at strategic points throughout the villa. This system is very effective as any accidental rupture of a pipe simply means that you can pull a new pipe through the ducting from one manifold to another. If you want to know more then do a Google search on Wirsbo. It is very effective and if you ever extend the villa it is relatively easy to extend the network of pipes.

Hi Rod,
I have a villa completed last December, we had central heating installed with combi boiler and the heating is controlled by thermostats on the radiators. I want to have more control of the heating, at the moment it is on or off, I have gone through the boiler manual but cannot see any where how I could wire in a programmer so as to have timed heating, any Ideas would be very helpful.

Sorry Keith - I can't really help on this one. I have a good knowledge of electrics, plumbing and most DIY stuff (now adapted to Portugal) but I've never installed a central heating system. I can only suggest that you contact the maker of the Combi Boiler (do a search on Google) and write to them for instructions. Is it an English Combi or Portuguese? If Portuguese then send me a PM and I'll try to write something for you.

Thanks Rod, I left the manual in Portugal, but I am back over in a few weeks, so I will try and source a local heating company who may be able to help. I have just spoken to a heating engineer here in Torquay and he says I should find a link on the boiler to connect a programer/ timer. So I am sure I will be able to achieve what I want to do.
