Intelligent central heating controls both save money and help to make life easier.
Central heating, on average, makes up around 82% of our total energy costs and with the average energy spend for a UK household in 2014 amounting to over £1300, this equates to nearly £1100 per year.
Therefore, any intelligent solution that helps us to make our homes more energy efficient, will show a significant long term saving.
Traditionally, we have radiators in our homes on a single-circuit, with a single thermostat that switches your heating on or off as appropriate.
Alternatively the heating circuits can be separated to operate independently so that there is a single circuit upstairs and one downstairs with each area controlled by two thermostats.
Whichever system you have, they are inherently inefficient, because the only way of sectioning each room is by the manually setting and resetting the thermostatic valves on each radiator to on when we’re in a room and off when we’re not.
Similarly, the only way to effectively monitor and control temperature in each room is to have a thermostat installed at eye level and not one or two thermostats located centrally in a hallway like in most homes.
Calder Services can install various intelligent heating controls to make your home more energy efficient.
Meet the 3rd-gen Nest Learning Thermostat. A thinner, sleeker design. A bigger, sharper display. And hot water control.
Your thermostat controls 60% of your energy bill, so shouldn’t it help you save energy?
The Nest Intelligent Thermostat does exactly this. Since 2011, it’s saved over 4 billion kWh of energy in millions of homes worldwide.* Because it learns from you. It gets to know the temperature you like when you’re at home. And turns itself down when you’re away. It even learns how your home warms up or how draughty it is, so it only uses the energy it needs. That’s how the Nest Thermostat saves energy.
Now the Nest Thermostat does something new when it sees you. It’s called Farsight, and it lights up to show you the temperature that you’ve set or the time. You can even choose a digital or analogue clock face. Farsight is big and bright on the beautiful display – you can see it from across the room.
Now, you can control your hot water tank with the Nest Thermostat. It comes with a hot water schedule – just adjust it from the Nest app. You can boost the heat so that you have extra hot water if you want it. And when you’re away from home for a few days, you don’t have to remember to turn off the hot water. The Nest Thermostat will do it for you.
Nest shows you how much energy you use every day in Energy History, and every month in your Home Report. So you can see when you use more energy, such as at the weekend or Monday nights, and how to use less.
Change the temperature to save energy and you’ll be rewarded with a Leaf. The Leaf learns how to help you save, so it appears at different temperatures for different families.

Honeywell Evohome is a sophisticated intelligent heating system that ensures you can create and individually control up to 12 heating zones in domestic properties. Evohome will also control domestic hot water.
Evohome is suitable for any home with a hydronic (wet) central heating system. Zoning solutions can be designed for even the simplest of property layouts. Evohome is ideal when looking to intelligently control temperatures in larger properties such as: luxury apartments; large family homes; homes with business use; multiple occupancy apartments and light commercial spaces such as doctors surgeries and small offices.
Evohome allows the installation of multiple intelligent temperature sensing devices around the property without altering existing pipework, disrupting décor or damaging fixtures and fittings.
With smart touchscreen control, the user can quickly gain control of exactly where and when the property should be heated.
Remote access is provided via a tablet or smart phone.
Wireless Radiator Controllers provide an easy way of installing heating zones without draining down or disturbing pipes or décor.
The multi-zone evohome controller controls the time and temperature of up to 12 heating zones plus a domestic hot water supply if required. Each zone has independent time and temperature control. It has a backlit colour LCD screen. The unit can either be wall mounted with an external power supply or table mounted on the table stand. This is powered by a 13amp power cable.
The evohome controller can be removed from the stand for easy programming for up to 2 hours before returning to the stand for charging.
The colour of the surround can be changed to either black or silver. A choice of idle screens, analogue or digital clock displays and a choice of day or night mode increases the aesthetic properties of the most visible part of the evohome system. When controlling the heating system the evohome controller has a number of features that make operation easy.
The evohome controller can act as a room thermostat on its own. Zone names can be input to match the actual property and the zones can be controlled as multi-room or as single-room zones. Zones can be configured to give individual local override of a room or rooms within the zone.
The programming in the unit is split between in-use and installation sections with a wide variety of control choices for the property owner. There is a guided scheduling wizard for the property owner to help them set up time and temperature profiles in each zone and a guided configuration facility for installers.
The screen will show energy efficiency messages to the homeowner as each zone’s temperature will be colour coded to show potential over or under set point temperatures. There are a number of quick actions available to make it easy to change the heating requirements for a short period.
The evohome controller provides access for the installer to fully control the heating system. It is suitable for radiators, hydronic under floor and a mixture of both types of heating. Cycle rates, minimum on times and fail safe parameters can be set.
OpenTherm capability is built-in to work with OpenTherm® boilers (not hot water systems). Boilers can be controlled by either a boiler relay or an OpenTherm® bridge. You can programme a temperature offset for the evohome controller screen when used as a temperature sensor in its own right.
Hot water cylinder overrun and temperature offset levels can be programmed as can the hot water temperature itself. You can carry out a wireless Radio Frequency (RF) check using the evohome controller screen. Wireless binding of the system components is carried out via the touchscreen and additional sensors can be easily bound in post application if the zoning requirements change.
In-built optimisation features such as ‘delayed start’ and ‘optimum stop’ allow evohome to intelligently optimise start and stop times. A learning TPI algorithm ensures each zone adapts to the weather and the seasons. When connected to the internet, via the remote access gateway, the evohome controller is able to display external temperatures.
evohome consists of a number of quality components manufactured by the UK’s leading manufacturer of home heating controls.
The radiator controllers use two-way communication with the evohome controller to ensure that commands are received and valves opened while maintaining boiler interlock.
These slim, ergonomically-designed radiator controllers will fit on most standard TRV bodies. They are battery powered with a two-year battery life and a battery low reminder visible on both the radiator controller screen and the evohome controller screen. The flip-up screen is backlit and can be positioned so that it can be easily viewed or folded away flat.
The backlit LCD screen displays the zone name, and local set point temperature. The local set point temperature can easily be overridden by turning the dial at the top of the radiator controller. Override temperatures can be set in half degree increments and are effective until the next scheduled temperature change. There is an open window feature that recognises sudden temperature drop and shuts off the local radiator. The zone temperature changes made at either the evohome controller’s screen or via the remote app will change in real time on the screen on the radiator controller.
Radiator controllers provide the optimum solution for installers when considering installing heating zones as there are no additional zone valves required which makes installation a lot quicker and cleaner. With existing TRV bodies already in place there is no need to drain down the system and they will fit on most compact radiators. They are easily bound into the system using the guided configuration feature in the evohome controller; binding confirmation is displayed on the screen. Controllers are available either individually or as a pack of 4.
You can also buy additional screen covers that allow the screen surround to be either silver or black, the set of covers also comes with a replacement white cover to ensure that any superficial damage to the surround can easily be replaced. Replacement evohome controller table stand and wall mounting kits are also available. Individual evohome components will be available as spares. If you wish to replace existing TRV bodies, a Honeywell valve kit (VHL120) is available.
The smartphone or tablet app that enables remote control of the evohome system will be available for download from the iTunes Store and the Google Play store.
Where there is a requirement to use a wireless room thermostat as a temperature sensor, both Honeywell’s DT92 Digital Room Thermostat and the Y87 Single Zone Room Thermostat can be included into the evohome system. Easy to set up with two way wireless communication (30m range) and a signal strength indicator. Simple to operate with up and down buttons (DT92) or by a turn of the Dial (Y87). Individual zone temperature override. 5 to 35°C set point range offers a wide range of comfort levels. The DT92 digital thermostat can be wall mounted or free standing to ensure best possible positioning. Y87 Single zone thermostat is wall mounted
Control domestic hot water via the evohome controller screen by installing an externally- mounted wireless cylinder thermostat onto the hot water cylinder; Sensors are provided for vented and unvented cylinders. Honeywell’s externally-mounted wireless cylinder thermostat is a combination of a temperature sensor that is mounted against the metal of the hot water cylinder and a wireless battery powered transceiver that communicates the water temperature to the evotouch controller.
The remote relay is wired into either a motorised zone valve or the boiler and provides the wireless interface between these devices and the evohome system. The relay box requires a permanent 230V~ supply.
To enable the evohome system to be controlled remotely by either a wifi-enabled tablet or smartphone, a remote access gateway needs to be connected to the internet network within the property. LED lights are provided on the gateway for feedback during binding and operation. This is achieved by connecting the supplied ethernet cable into the remote access gateway and a spare ethernet port on the home broadband router. The remote access gateway is powered by a supplied 13 amp power supply and there is one button binding of the gateway to the evohome system via the evohome controller. Once bound, the homeowner is then able to visit the total connect website to register their evohome system, uniquely identify their evohome remote access gateway (MAC ID & CRC code) and receive instructions on how to download the smartphone or tablet app that suits their Apple or Android system.
By controlling the hydronic under floor heating via the Honeywell under floor heating controller, the time and temperature of the under floor heating can be achieved via the evohome controller screen. The under floor heating controller provides for up to 5 zones of under floor heating and the optional extension controls a further 3 zones. It operates on the same 868 MHz frequency as the rest of the evohome components and has an internal antenna.
