• An individual heating system tailored to suit the specific needs of the project is determined.
• On acceptance of a quote we produce drawings on CAD showing element layouts and recommended thermostat positions.

UNDERFLOOR HEATING SYSTEMS
We specialise in designing two different underfloor heating systems: storage and direct acting. If you are unsure which is the most suitable for your requirements, please get in touch and we will be happy to offer advice.

Storage Underfloor Heating
Storage underfloor heating makes use of the cheap rate electricity available to everyone on the Economy 7, or other time of day tariffs, to provide a comfortable background temperature at all times. In the winter periods it is possible to use the cheap rate electricity to provide a large percentage of the heat required. Storage underfloor heating normally uses a higher wattage cable in a 60-80mm screed, laid directly on to a concrete slab to give the maximum thermal mass around the cable, allowing as much heat to be stored in the slab as possible.

CEILING HEATING
ERHS supplies and installs modern ESWA electric ceiling heating systems that work by using the ceiling as a low temperature, large surface area radiator. Insulation is installed above the elements to prevent heat loss upwards. The system gently warm the surfaces of the room, which then warm the air within the room by conduction, rather than over heating the air directly like old fashioned, less efficient heating systems.

HEATING CONTROLS
As the UK’s original supplier of electric heating systems, we pride ourselves in the wide range of heating controls we stock.

Browse our range of thermostats, power regulators and clocks for an overview of what each can offer. If you have any questions about which heating control is best for you, please get in touch and we will be happy to offer advice.
