DHI Solar Water Heater

DHI solar water heaters are available at Sewas Mart across four tube configurations,
with prices starting from Rs. 36,000 for the 15 Tube 200L model
through to Rs. 71,500 for the 30 Tube 375L model. DHI sits in the
mid-entry segment of Nepal’s solar water heater market — priced slightly above Appolo,
with consistent evacuated tube construction that holds up well across Nepal’s different
climates. If your primary question is how DHI compares against every other brand currently
available in Nepal, our complete
solar water heater price guide covers all seven brands side-by-side with
current prices.

DHI Solar Water Heater Price in Nepal 2025 — All Models

All DHI models use evacuated tube technology with a 1500W electric backup heating element
and SUS304 stainless steel inner tanks. Prices below are current Sewas Mart selling prices,
updated April 2025. Free delivery and installation is included within Kathmandu Valley.

Cash on delivery available. Free delivery and professional installation within
Kathmandu, Bhaktapur, Lalitpur. Call

Which DHI Model Do You Need?

The DHI 15 Tube at Rs. 36,000 is the right starting point for a
household of 3–5 people sharing one bathroom. It is Rs. 1,500 more than the Appolo
15 Tube and delivers comparable evacuated tube construction — a sensible choice if you
want to step slightly above the entry-level price point without committing to a premium
brand. For a detailed breakdown of everything available at this capacity, browse our
200
litre solar water heater page where DHI competes alongside Appolo, Neo,
Volta Sun, and others.

If your household has 5–6 people or two bathrooms in daily use, the
DHI 20 Tube at Rs. 52,500 is the step up that makes sense. An
extra 50 litres of storage means the last family member to shower gets hot water without
the backup electric element compensating — which over Nepal’s six winter months translates
directly to a lower NEA electricity bill. Compare all 250 litre options on our
250
litre solar water heater page.

The DHI 24 Tube (Rs. 62,500) suits joint families of 6–8 people
or homes where two bathrooms are used simultaneously during morning peak hours. The
DHI 30 Tube at Rs. 71,500 handles larger households, small
guesthouses, and office buildings where 8–12 people need hot water across a day. For
anyone evaluating the 30 Tube, compare it against the full field on our
350
litre solar water heater page.

Who Should Choose DHI — and Who Should Look Elsewhere

DHI makes the most sense for buyers who want a step up from the absolute floor price
without paying for premium brand positioning. The build quality is consistent, the
1500W backup element is standard across all models, and Sewas Mart provides full
after-sales service for every DHI unit we supply.

Choose DHI if: You want solid mid-entry value at all four capacity
points. You are in Kathmandu Valley or the Terai where year-round solar irradiance
is reliable. You want free installation from Sewas Mart without a premium brand
price tag.

Consider alternatives if: Warranty length is a priority — DHI carries
a 1-year warranty, while Neo
offers 5 years on their full range. If you are in a hilly region with heavy monsoon
cloud cover (Pokhara, Dharan), the higher-grade tube coatings in Neo or
Ultra Sun
maintain better output on overcast days. If your building has high-pressure pump-fed
plumbing, DHI’s evacuated tube system is not compatible —
Osmo’s
copper panel range is what you need instead.

DHI Solar Water Heater Performance in Nepal’s Different Regions

Kathmandu Valley: The DHI 15 Tube performs reliably year-round in
Kathmandu, Bhaktapur, and Lalitpur. The valley’s mild winters (rarely below 2°C at
floor level) do not significantly stress the evacuated tube system. During the
December–February fog season, output reduces moderately but the 1500W backup element
compensates on low-sunlight mornings without a major electricity cost impact.

Terai region (Birgunj, Butwal, Chitwan): DHI models outperform their
ratings in the Terai’s strong year-round sunshine. A DHI 15 Tube in Birgunj will
reliably heat its full 200 litres by mid-morning on a clear winter day. If your Terai
home uses borewell water with high mineral content, note that DHI uses standard SUS304
inner tanks without additional scaling protection —
Supreme’s
ceramic-coated tank or Ultra Sun’s magnesium anode system may better
suit hard-water sources.

Hilly regions (Pokhara, Dharan, Dhulikhel): DHI works in hilly Nepal
but we recommend sizing up one capacity step from what you would need in Kathmandu.
A hilly-region family of 4 that would use the DHI 15 Tube in Kathmandu should consider
the DHI 20 Tube in Pokhara — the extra storage buffer handles reduced solar yield
during heavy monsoon cloud cover without relying on the electric backup every evening.
