FAQs
Why should I consider upgrading my existing thermostat?
Older manual or basic digital thermostats can only turn your heating or cooling on and off at a set temperature. Modern programmable and smart thermostats add scheduling, remote control and self-learning features that can cut unnecessary run-time, improve comfort and typically reduce energy bills by 10–20 %. They also give you better visibility of your energy use and can alert you to faults in your boiler or air-conditioning system before they become costly repairs.
What types of thermostat upgrades do you install in Bristol?
We supply and install three main categories: 1) Programmable digital thermostats that let you create 5/2 or 7-day schedules. 2) Wi-Fi-enabled smart thermostats (e.g., Nest, Hive, Tado°, Honeywell Home) that you control via an app or voice assistant and that can learn your routine. 3) Zoned control systems that use multiple smart thermostats or smart TRVs to heat different rooms independently. We will advise which option best matches your boiler, heat pump or air-conditioning setup.
Will a new smart thermostat be compatible with my current boiler or HVAC system?
In most Bristol homes the answer is yes. Smart thermostats work with the majority of 24-230 V heating systems, including combi and system boilers, heat pumps, and conventional split-system air-conditioners. During a free survey we check the control wiring, voltage, number of stages and whether an OpenTherm or on/off interface is present. If any additional relay or a common "C" wire is required, we can fit it during installation.
How much can I realistically save on my energy bills?
Savings depend on how you currently use your heating and cooling. Ofgem data show that heating accounts for about 55 % of an average UK home’s energy spend. Customers in Bristol who switch from a manual thermostat to a properly programmed smart thermostat typically report annual savings of £80–£180 on gas and 5–10 % on electricity for cooling. Features such as geofencing, weather compensation and open-window detection further boost savings without sacrificing comfort.
What is involved in the installation process and how long does it take?
A standard upgrade takes 1–2 hours. Our qualified heating engineer will isolate the power, remove the old thermostat, test the existing wiring, fit any required back-plate or C-wire adaptor, and mount the new thermostat in the optimal location. We then power up the system, pair the thermostat with your Wi-Fi, update firmware, set an initial schedule and show you how to adjust settings through the app or on the device itself. All work is carried out in line with Part P electrical safety regulations.
Are there any rebates or incentives for thermostat upgrades in Bristol?
While England currently has no nationwide grant exclusively for smart thermostats, some energy suppliers include them in ECO4 or Boiler Upgrade Scheme packages. Bristol City Council’s City Leap initiative may also run periodic incentives for energy-saving controls. We monitor available schemes and can advise you at the time of quotation if you qualify for a discounted or free thermostat under any local or supplier-funded programme.
