Part 9 · In the Valley
10 min readFour projects, including the parts that didn't go to plan
These are composite examples rather than named customers — assembled from the situations that recur in the Valley. Every one of them carries the compromise that was made, because a case study without a compromise in it is a brochure with a photograph attached.

Rajbagh, Srinagar
A third-floor flat that could not touch its own slab
The situation
- A family of four in a 1,250 sq ft flat, heating the drawing room and one bedroom with an LPG heater and a blower. The blower dried the room out and the children would not sit on the floor.
- The building society's rules prohibited any cutting of the structural slab, which ruled out a full screed build-up before the conversation started.
- The sanctioned load was 4 kW, already tight with a geyser and a washing machine.
What was done
- Two zones only — the drawing room at 200 sq ft and the bedroom at 130 sq ft — rather than the whole flat. Roughly 5 kW connected across both.
- A dry-fit low-profile mat over 8 mm dense insulation board, finished with self-levelling compound and the existing tile relaid. Total build-up 22 mm.
- Sanctioned load enhanced to 8 kW before work began. This took longer than the installation itself.
- Separate thermostats per zone, scheduled to warm the bedroom overnight and the drawing room from late afternoon.
How it turned out
- Both rooms reach working temperature in a little under an hour from cold and hold it without the family thinking about it.
- Through the season the two zones together run at roughly ₹1,400–1,900 a month on the household's tariff — comparable to what the LPG and blower had been costing, with dramatically better comfort.
- The floor is where the family now sits, which was the actual objective.
The compromise
Eight millimetres of insulation is not fifty. Had the slab been available, the same two rooms would run measurably cheaper. The household chose permission and speed over efficiency, knowingly.
- Rooms heated
- 18 bedrooms + baths
- Zones

- Left unheated
- Corridors, reception
Gulmarg
A hotel paying to heat empty rooms
The situation
- An eighteen-room property running electric wall convectors, with a February bill that bore no relationship to February occupancy.
- Guests arriving off the road at midnight found cold rooms, and the convectors took the edge off the air without ever making the floor bearable.
- Staff were switching heaters on manually in rooms that were then not sold.
What was done
- Bedrooms and bathrooms heated; corridors, reception and the dining room deliberately left out. Budget went where guests are barefoot.
- One zone per room, each on its own circuit, with a central controller at the front desk linked to the booking sheet.
- Cable and self-levelling screed during the closed season, room by room, so the property never lost more than four rooms at a time.
- Adaptive scheduling: a room booked for tonight begins warming three hours before check-in and drops back afterwards.
How it turned out
- Unsold rooms cost nothing, which was the entire point. Off-peak months stopped being punitive.
- Guest complaints about cold rooms fell away, and the property stopped keeping convectors as backup after the first full winter.
- One failed circuit in the second season meant one room out of service for two days, not a wing.
The compromise
Corridors stay genuinely cold, and some guests notice walking between the room and the restaurant. The management considers this an acceptable trade for the bill; not every property would.

Downtown Srinagar
A traditional stone hamam that stopped being fired
The situation
- A large old house with a proper stone hamam built two generations ago, in a family where nobody left was willing or able to fire it daily.
- Firewood had become expensive and awkward to store, and the smoke had blackened the room over decades.
- The elders did not want the hamam room changed. They wanted it used again.
What was done
- The existing hamam room was kept as the hamam room. The stone floor was lifted carefully, numbered, and set aside.
- The old firebox chamber was filled and consolidated to give a sound base, then insulated properly — the first time that floor had ever had insulation under it.
- Cable laid at calculated spacing, screeded, and the original hamam stone relaid on top.
- A single thermostat, scheduled for the hours the family actually uses the room.
How it turned out
- The room looks almost exactly as it did, down to the same stones in roughly the same places, and it is warm every day rather than on the days someone had time to fire it.
- The stone's mass, which was always the strength of the original design, now works in the family's favour during outages — the floor holds warmth well into a long evening cut.
- No smoke, no wood store, no soot.
The compromise
The oldest member of the household maintains it is not the same, and is not wrong. The fierce heat of a freshly fired stone hamam is gone, replaced by something steadier and cooler. Some of what was lost was not a technical property.
- Heated area
- 185 sq ft, 2 zones
- Build-up added
- 11 mm
- Never simultaneous
- Zones staggered by design
- Season gained
- Roughly doubled
Nigeen Lake
A houseboat with 11 mm to spare
The situation
- A heritage houseboat let to guests through the shoulder season, unusable in deep winter because the deodar floor sat directly over cold water.
- Shore supply was shared and limited, and the owner had already had one electrical scare with an earlier heating attempt.
- Raising the floor by any meaningful amount would have fouled the carved door frames, which were not negotiable.
What was done
- Two small zones only — the sitting room and one bedroom — sized to what the shore supply could genuinely carry.
- An ultra-thin mat over 6 mm board with a full vapour barrier beneath, total build-up held to 11 mm so the original door frames were untouched.
- Dedicated RCD-protected circuit, full earthing, and insulation-resistance readings recorded at all three stages and handed to the owner.
- A conservative schedule that never brings both zones up simultaneously.
How it turned out
- The boat now lets through winter, which roughly doubled its usable season.
- Nothing structural was altered and the door frames were never touched.
- The owner holds a folder of test certificates, which turned out to matter more to prospective guests than the heating itself.
The compromise
Six millimetres of insulation over water is the bare minimum, and the running cost per square foot is the highest of any project here. The alternative was not a cheaper system; it was no system.
What they have in common
Every one of them heated less than the owner first asked for
In each case the project got better when it got smaller: fewer zones, done properly, with the insulation intact and the load calculated honestly. That is not a coincidence, and it is the closest thing to universal advice this site has.
