Any ideas

[jason121]

Hi Looking for some ideas on how to heat an house without radiators and under floor heating. The property has heat recovery. Ideally by using solar thermal. thanks in advance

Log burning stove???/

 

[jason121]

No she don't want log burner

coal burning stove

 

[jason121]

no stoves of any kind

 

[Pete999]

storage heaters

 

[jason121]

Ideally something eco

sorry I give up

Looks like it will be some sort of blown air system then....
Solar thermal won't get very hot when you really need domestic heating will it???

They are trying to be 100% eco friendly. The house is very close to being A rated. Full heat recovery being installed, looking to top the heating for the cold nights.

Sweater, hot water bottle or maybe a little hanky panky.....

Solar Air Panels - I'll post a link

Here it is:
$350 Thermosyphon Solar Air Space Heater (with 1 year payback)

That is plan B, back to basics

Is it a passive house? The heat recovery system only recovers about 80% of the heat which is already in the house. Still needs a form of heating. Most of the eco houses I've been in use a ground source heat pump or solar used to heat an underfloor heating system.

Passiv haus - usually the form of heating would be bodies ( each person ~ 3kW) and solar gains through glazed areas.

They are trying to make it a passive house. They don't want radiators or underfloor.

Hi Worcester , is it really 3kw per person !?
I saw some research a few years back , that was for cows while they are in the parlour being milked , and it suggested they give out 1kw each .
Now this was a few years ago now and no doubt the way they process the data is differently / more effectively done , but that is one hell of a uplift when you take into account the size of a cow .
I have no doubt you are correct , but thought I would just mention that anyway .

@JD6400, have to admit it was a guess, turn out it was one of those urban myths that I just propoagted

Bit of investigation turns out that in architectural planning for solar space heating systems the rule is 100W per at rest person
The same figure is used by event planners when looking at heating and cooling requirments in venues.
