Heating controls for your central heating system

Your hot water and central heating system is a complex system and needs controls to make sure that they are running optimally and also to the required user level. At a minimum you would want to control the temperature of your hot water and central heating, when your hot water is available and at what times you require your central heating. This is all possible with the aid of controls, ranging from the most basic mechanical controls to the latest in cutting edge wireless technology.

 

Control requirements

energy efficiency

 

With the Building Regulations part L the requirement for heating controls within your home are more stringent and a number of minimum requirements are now mandatory. All new or upgraded central heating systems must have separate controls for hot water and heating through a time switch and room thermostat (where applicable), also include a cylinder thermostat

(if applicable) and thermostatic radiator valves on all radiators (at least those in sleeping areas).

 

heating controlsAlthough some may view these regulations as too stringent they do ensure that you are preserving energy, saving you money and more importantly the environment. For example ensuring that the heating system does not over heat by 1°C could save you 10% of your fuel bill, please visit our energy efficiency information page for more info.

 

What we offer

 

By ensuring that you have the right controls in your home you are not only saving money and the environment but you are also ensuring that you are living in comfort and control. There are many types of controls currently available giving you choice and flexibility to choose the right control for your requirements. We always like our customers to feel in control in their own home which is why we only offer controls that not only perform to excellent standards but are also easy to use, a consideration that is often overlooked.

 

Of course we can supply and install more technically advanced controls such as 7-day wireless programmable thermostat, but we can also provide a simple on/off thermostat. To offer the best energy efficiency and comfort levels we would always recommend as many controls in your home as possible or required, although we do firmly believe in using technology to meet a purpose, rather than to find a purpose.

 

There are many types of controls available, not to mention hundreds of different models each offering a certain number of features. If you require any assistance in choosing the right controls for your system please contact us.

 

Types of controls

 

 

programmer

Programmer

A programmer controls the boilers operation period in terms of hot water and heating requirements. A programmer simply switches your boiler on or off at programmed times throughout the day(s). They are available in multiple or single channels with single day (7 day), weekday/weekend (5/2) or weekly options. On a combination boiler a programmer would not be used to control hot water as this requirement is provided by the boiler directly and instantaneously.

 

time switch

Time switch

A time switch is a basic version of (and is included within) a programmer apart from a time switch is not programmable in its own right and so does not provide independent control over hot water and heating. A time switch is simply an on / off switch typically used in conjunction with a more advanced programmer or thermostat and are compatible with combination boilers.

 

room thermostat

Room thermostat

A room thermostat is used to provide the user with control on the overall room temperature by using an inbuilt thermometer to monitor air temperature and then sends a signal to the boiler to switch on or off in order to reach the desired setting. A room thermostat can be mechanical or digital (Digistat) and also can be available in a wireless format, enabling easier installation and increased flexibility.

 

programmable room thermostat

Programmable room thermostat

Much like a room thermostat a programmable room thermostat controls the overall room temperature. However you can also program different temperatures at different times of day, offering further flexibility and increased comfort levels. As with a programmer they are available in different options depending on the number of days that are required to be programmed.

 

 

 

thermostatic radiator valve (TRV)

Thermostatic radiator valve (TRV)

TRV's are used to control the heat output of your radiators, this is achieved by controlling the flow of hot water to the radiators. The TRV can be set to a specified number usually 0 to 10 (0 being fully off and 10 being fully on) and reduces or increases the hot water flow to the reach the desired temperature setting. It is always best to keep the settings within 1 to 9 and not switched fully on or off to maintain optimum efficiency levels. TRV's can also be controlled using radio frequency though a programmable thermostat.

 

cylinder thermostat

Cylinder thermostat

A cylinder thermostat is used to control the temperature of stored hot water within a cylinder to a required level. It is generally not recommended to keep the stored hot water below 60°C as to reduce the chances of legionnaires disease and not above 65°C / 70 °C to reduce scaling or more importantly scalding. A cylinder thermostat can also be of a programmable type offering multiple day and temperature combinations.

 

 

frost thermostat

Frost thermostat

A frost thermostat is used in situations where a boiler is susceptible to frost such as in a garage or outside. The device will be programmed to come on at a pre-programmed temperature to provide protection for the boiler against frost damage. In order for frost thermostats to function as required they are designed to override all existing controls, and are sometimes built into some modern boilers.

 

pipe thermostat

Pipe thermostat

A pipe thermostat is as the name suggests used within a pipe to measure the temperature of flowing water. A pipe thermostat is normally used in conjunction with other controls such as a frost thermostat. Pipes located outside are at more risk of freezing and so a pipe thermostat can monitor and report to a frost prevention device which can then make the appropriate action.

 

In addition to the above controls we also attend to every other type of control on your central heating or hot water system. We can attend to repairs or maintenance and install any of your central heating controls (in addition to the above) including motorised valves, automatic bypass valves, 2-port and 3-port valves and also pumps, please contact us with your requirements.
