'Easy Pick Thermostats By Discounted Heating' |
| |
Programmable Thermostat:-
A combined timer and room thermostat that allows for different time and temperature levels to be set. |
Radio Frequency Thermostat:-
An air temperature sensing and switching device that operates by radio signal, hence removing the need for wiring. |
Setback Thermostat:-
These units switch between set temperature level rather than turning the system on/off. |
Standard Thermostat:-
A sensing device used to control the air temperature within a room by switching on and off the space heating. |
Practical Advice on Thermostats:-
Should be sited about 1.5m above the floor in a regularly heated area which allows free circulation around it, not exposed to draughts, away from internal heat sources e.g. radiators, away from outside heat sources e.g. sunlight and in a position readily accessible to the householder. i.e. not in cupboards, behind furniture, etc. The room thermostat should not be sited where supplementary room heating or heat emitting appliances will affect it. Appropriate positions will be in the hall or other living room. It should not be sited in a kitchen or combined kitchen/dining room.Wireless units are now available which provide increased flexibility in positioning and eliminate visible wiring as they communicate by radio frequency signals. |
Cylinder Thermostats:-
Non Electric
Devices that are fitted to the flow or return pipework of the cylinder and control the stored temperature by inference. |
Programmable Cylinder Thermostats:-
A combined time switch and cylinder thermostat, which allows the user to set different periods with different target temperatures for stored hot water, usually in a daily or weekly cycle format. |
Strap-on and Immersion Cylinder Thermostats:-
A temperature sensing device that is either strapped onto or immersed in a pocket within the cylinder. |
Practical Advice on Cylinder Thermostats:-
Should be strapped on to the cylinder at a height of about 1/3 up from its base – the strap should be tight for good thermal contact. It should be adjusted to around 60oC. If set too high it may give rise to scaling and scalding, and if set too low it will increase risk of the growth of legionella bacteria which could lead to serious health problems. |
Pipe Thermostats:-
A sensor measuring the temperature of water flowing through a pipe. Normally used in conjunction with other controls such as a frost thermostat or boiler management control sets. |
Frost Thermostats:-
A device or set to detect low air temperature and switch on protection to avoid frost damage. Arranged to over-ride all other controls. |
