Heating system installation

Heating system installation in India

Updated 31 October 2026

Most heating jobs in India are radiators, central water-heating systems or underfloor heating for one home. Underfloor heating costs about ₹150 to ₹350 per square foot for the system, plus installation, while a 33 kW central gas boiler was listed at about ₹103,840, according to sellers' websites in October 2026.

Certification and the electrical supply

Water heaters sold in India fall under BIS quality rules, and the snippets point to the ISI mark as the sign of a certified product, so check the label on any heater before you buy. Solar water heaters have their own standard, IS 12933. The main cost driver for a boiler is often electrical: cabling and a dedicated power connection, and a large unit may need a three-phase 415 V supply. Ask the installer whether the supply is adequate before the quote is final.

Season and timing

The climate is tropical: hot all year, with a wet season and a dry season. October is when the monsoon ends in most of the country, so walls and floors dry out and installers can work on screed and pipework. Heating is needed mostly in the cooler months, so book the job now if you want it working before they arrive. Ask the installer how the wet season affects their schedule for the work.

How the job is quoted and delivered

Radiators and boilers are quoted per piece, and underfloor systems per square foot, with installation priced separately. Listings use square feet, but measure the heated area in square metres and ask for both figures. Say how many rooms need heat, the heat source, the pipe route and the site address in Mumbai, Delhi, Bengaluru, Hyderabad or Chennai. Ask for the warranty term in writing.

BlaBlaPrice is free for buyers. Describe the rooms, the heat source and your budget in a chat, with a photo if you have one.
