Good Evening,
We live in an old stone farmhouse which we are steadily 'improving' as the years go by.
The heating is provided by a CTC GSi 12 GSHP feeding UFH in the kitchen and Dining Room and radiators elsewhere.
The time is fast approaching when the bathroom is due a workover. In common with other farmhouses of this vintage the old pantry is the location of the bathroom and, as a result, it is a relatively small space as the attached plan shows.
My intention is to fit UFH.
The floor will be filled and a concrete sub-base installed overlaid with 200mm of Celotex.
The partition walls to the Utility Room and Lobby are already filled with 50mm Celotex and will be overlaid with a further 20/ 25mm to eliminate cold bridging. The walls against the stone walls will be framed and filled with Celotex and again overlaid with a further layer of Celotex.
The ceiling and 'chimney' to the Velux window will be filled with 50mm Celotex and the horizontal surfaces overlaid with 200mm fibreglass. The framing around the chimney will be infilled and overlaid with 50mm Celotex.
The existing Velux S06 window will be replaced with one of the new GGU 008230 SK06 models.
I need advice on how to maximise the layout of UFH pipework in the space available as I would like to avoid having to install a radiator. We do, however, intend to fit a towel radiator.
I have thermometers in the bathroom and the figures are:-
Radiator inlet - 40.0°C
Radiator outlet - 24.4°C
Room temperature - 20.8°C
The radiator fitted is an Ultraheat 9TS900 which as an output of 3103W at a ∆50.
The mean flow temperature is obviously 40 + 24.4 = 64.4/ 2 = 32.2°C
The room temperature at 20.8°C therefore gives us a ∆ of 11.4°C which is clearly a lot less than a ∆50.
The multiplication factor is 0.136 (derived from manufacturers’ figures) so the actual output of the radiator right now is a mere 422W and the outside temperature is 1°C.
At the end of the improvements less heat will be required than currently.
The question is I have a total floor area of 5.82m2 so allowing for only using 90% of this i.e. 5.24m2 will I be able to generate enough heat?
Regards
Richard
