Garden Room Heating: Infrared, Underfloor and Other Options

Estimate the room’s heat demand first

Heating choice starts with the room’s size, insulation, glazing, air leakage and how often it is occupied. Ask for the full thermal specification and a heat-loss estimate for the proposed design. A room used briefly on weekdays may favour quick response; a room occupied for long periods may value even temperature. Neither pattern proves that one product has a universal running-cost advantage.

Understand infrared heating

Infrared panels deliver radiant heat to people and surfaces in their path. Placement matters: a panel blocked by furniture or aimed away from the occupied area will feel different from one above a desk. Ask how controls and sensors will be placed, what electrical capacity is needed and whether the user will still be comfortable near large windows or on a cold floor.

Understand underfloor heating

Underfloor systems can free wall space and provide a different comfort pattern, but floor build-up, warm-up time and repair access matter. Ask whether the proposal is an electric mat or a water-based system, what subfloor and floor finish it needs, and whether the electrical or plumbing work is included. For a small intermittently used room, compare the total installed cost as well as the energy used during actual occupancy.

Price controls and installation

Ask for the proposed heat-loss calculation, heater output, thermostat location and wiring diagram. A simple schedule or remote control may be more valuable than an unverified “AI saving” claim. Have a competent electrician plan and certify work where required. Compare running costs using your tariff and likely hours rather than a generic advert. See the cost guide for complete quote items.
