Control your heating, room by room.
Honeywell's 'evohome' system was the first product that invented this market space by developing a system that allowed home owners to control the home's temperature by creating individual heating schedules room by room or by ‘zone’ via your thermostat, phone or tablet.
One of the biggest blockers with zonal heating for customers is cost, the system needs to be professionally installed, and each radiator within the home needs a smart TRV (Thermostatic Radiator Valve) attached, linked to and controlled by the thermostat and the app. Depending on property size, number of rooms or zones and radiators costs can reach thousands, but it has many benefits to the home owner, enabling them to tailor and distribute heating room by room, giving control to rein in energy wastage and reduce heating bills.
As such Zonal heating is a niche but growing market in Europe, where radiant and underfloor heating amounts to over 75% of the heating types used within the home space.
A brief was set by the business to extend the comfort portfolio for zonal heating under the ‘evohome’ range, by developing a lower cost TRV to engage the lower end of this market segment. Including smart and energy conscious users who want to benefit from an affordable zonal heating solution. Contractors and Building owners who want lower system costs with optimized functionality to control energy budgets and usage.
Design Process
Design Process
One of the first comfort projects to utilize a newly created and aligned brand framework, category core values and philosophy which help inform aesthetic directions across all business categories reflecting the Honeywell brand ethos to it's customers. While creating a legacy and visual link to the HR92 evohome TRV, the premium sibling to which the HR91 would share components with.
Design and value engineering constraints were in place to drive both reuse of internal components from the existing HR92 TRV such as the motor and gear train, battery layout and contacts, valve connector and locking mechanism. In addition to lower part costs of plastics and PCB to meet the set BOM and price points based on functional requirement levels for the targeted segment market.
Iterative development loops with ME and Business partners ensured the desired outcome was reached from both a design and manufacturing perspective. With added Alpha testing by installers meant an improved install process and functionality needs were met.

Mounting Orientations
Depending on country or radiator type, TRVs are mounted either at the top or base of the radiator. Mounting Orientations
