ᐅ Heating the terrace area / entrance vestibule?

Hello everyone,

I am still BEFORE the actual construction of my house, but I am already thinking about how to keep the terrace warm.

Why?
1. Because I always feel cold everywhere, and I never want to experience that again.
2. Because I want the terrace to be an active part of the house, even in autumn and winter.
3. Because maybe something needs to be installed in the foundation slab or house wall (electricity/gas).

Speaking freely and without much expertise, I keep thinking about a terrace with a slatted floor and heat coming from underneath.
But that would really be a waste of energy, so maybe infrared heaters mounted on the house wall would be better?

According to the floor plan, my house is 10 meters (33 feet) wide, so the terrace wall is also 10 meters (33 feet) wide.
On the right and left sides, there is an enclosure with a concrete/stone wall.
The terrace itself is 4 meters (13 feet) deep, then the lawn area begins.
The easiest (and probably cheapest) solution would be to put an awning over the window front (which spans the entire 10 meters (33 feet))
and install long infrared heaters underneath. When it gets cold, the awning can be extended. The walls are on the right and left, so the heat could radiate downwards.
Could it really be that simple? I worry that if a table is placed, say, 1 meter (3 feet) away from the wall, the people sitting on the outside (around 2.5 meters (8 feet) from the wall) might not get warmed.

What do you think - how have you solved this? You can spend a lot of money, just on wind protection it's easy to spend 10k.

Best regards,
Flo

Infrared heaters are probably the most common option. You should forget the idea of heating 40 square meters (430 square feet) outdoors to room temperature – that's simply unrealistic. Alternatively, you could build a heated conservatory, but at that size it won't be cheap. However, it would be a genuine extension of your living space (you could plan for a dining area, for example).

We installed a 3kW Solarlogic infrared heater in the covered part of our terrace roof. It can be controlled via a smartphone and comes with a remote control offering three heat settings. It’s great for sitting outside with friends who feel the cold in autumn. First, you bring out the blankets, then switch on the heater. The heat coverage easily reaches six people. We don’t use it very often, but when we do, it definitely adds to the comfort of the situation.

Yes, that’s exactly what I’m looking for. But that’s what you talk about. I thought by now there might be something that heats from underneath. Nope, then we’ll go with infrared heating as well.

With spotlights, whether infrared or gas-powered, you face the same problem as with fire. Everything within the beam area gets warm, while the rest remains cold.

It could have been possible that there is something now that heats from below.

Heating from below when it’s cold above – how uncomfortable!

That’s not an issue as long as you’re sitting reasonably within the radiation area. Also, outdoor heaters work differently (more like the red light used for incubating eggs) than indoor heaters, which don’t emit light. The warmth is very pleasant.

So the head doesn’t get hot and the feet under the table don’t get cold. Not bad then.

Ok, I don’t need that, I’m not sensitive to cold and if I were, I would really consider having a heated sunroom. Last year, at -20 degrees Celsius (−4°F), I actually had to bring out ski pants and long underwear.

Nobody needs something like that—especially not as an extension of living space to the outdoors during colder days. It’s a nice feature if you want to stay outside longer during the transitional seasons, enjoying fresh air with wine and cheese while having a good conversation you don’t want to interrupt. A heated sunroom is not outdoors but an actual room. We also have large windows in our living area, facing every direction.
