Frequently Asked Questions

Which stove is right for my room size?

As a general guide: EcoMini for small rooms up to ~200 sq ft, Eco1 for medium rooms (200–400 sq ft), Eco2 for large rooms or two connected spaces (400–600 sq ft), Eco3 for very large rooms, halls, or commercial guesthouses (600+ sq ft). When in doubt, message us on WhatsApp with your room measurements — we'll recommend the right one.

What's the difference between the Eco1, Eco2, and Eco3?

They use the same combustion technology and wood feeder design. The difference is height — and therefore heat output and visual presence. Eco1 (500mm) is the most popular household model. Eco2 (625mm) gives more heat for larger spaces. Eco3 (825mm) is the most powerful and suits very large rooms. All three take the same pipe kits and accessories.

Can it cook as well as heat?

Yes. All Eco stoves have a flat top surface where you can place a vessel for boiling water, making tea, or reheating food. For dedicated cooking use, the Eco Duo range is designed specifically with cooking as a primary function alongside heating.

Is it suitable for my flat in a city?

Rocket stoves require a chimney exhaust — you need to run a flue pipe out of a window or through a wall. If you can do that, the stove works in any home. Many urban users in cold northern cities like Shimla, Manali, Mussoorie, and Srinagar use our stoves. If you're unsure about installation feasibility, message us and we'll help you figure it out.

Does it come with a chimney pipe?

No — the stove comes without pipe. We sell Window Pipe Kits (3 indoor pipes, 3 outdoor GI pipes, 2 elbows) and Straight Pipe Kits (5 indoor pipes, 1 outdoor GI pipe, wind cap) separately. Both are designed to fit all Eco models. Standard 4-inch flue pipe from a local hardware shop also works.

How difficult is installation?

Most customers install it themselves in under an hour. The stove sits on the floor. You connect the pipe from the exhaust hood and run it through a window or wall hole. We provide full installation guidance over WhatsApp or a call.

Do I need a professional to install it?

Generally no. If you're comfortable with basic DIY, you can install it yourself using our guidance. For through-wall installations (cutting a hole in a wall rather than using a window), you may want a handyman to make the wall penetration.

What wood should I use?

Any dry hardwood works well — deodar, oak, sheesham, acacia are all excellent. The key is that the wood should be dry (seasoned). Wet wood produces a lot of smoke regardless of stove design. Avoid very resinous wood like cedar or blue pine in large quantities — mix it with non-resinous wood.

Why does it still smoke at the start?

All wood fires produce smoke while they're warming up. After 10–15 minutes as the stove reaches operating temperature, smoke drops dramatically. If your chimney is still smoking heavily after 20 minutes, the most likely cause is wet wood. Try fully seasoned (dried) wood.

How much wood does it use per day?

It varies by weather, room size, and how long you run it. Compared to a traditional Bukhari or Chulha, expect to use approximately 50% less wood for the same level of heat. In practice, most families report halving their monthly wood bill.

Where do you deliver?

We deliver across India. Most deliveries within Himachal Pradesh, Uttarakhand, Jammu & Kashmir, and nearby mountain states take 3–7 business days. Other parts of India may take longer. Message us with your specific location and we'll confirm.

How do I order?

The easiest way is to message us on WhatsApp — tell us your location, model of interest, and room size. Alternatively, you can add to cart and pay securely online via Razorpay (UPI, cards, net banking). After payment, message us on WhatsApp to confirm delivery details.

Can I pay in instalments?

Currently we require full payment at the time of order. Some bank cards offer EMI on Razorpay — check at checkout if your card is eligible.

What is the warranty?

All Eco stoves come with a full 3-year warranty on all parts. If any component fails under normal use within the warranty period, we will replace it.

How long do they last?

The lifespan of a well-maintained HRS stove is measured in decades. We have stoves that have been running since 2013 with no major issues. The SS310 stainless steel internals are specifically chosen for long-term heat resistance.
