 ELECTRICAL SURFACE HEATING PROJECT SPECIALISTS FOR A WIDE RANGE OF APPLICATIONS AND INDUSTRIESELECTRICAL TRACE HEATING 
The term "trace heating" describes the application of heat to the surfaces of pipelines,
tanks, vessels and similar items, whether continuously or intermittently, to raise and/or
regulate temperature around and inside those items. The term "surface heating" is also sometimes used. Electrical trace heating will: In principle at least, there are very few factories or large buildings in the UK, or indeed worldwide, which could not benefit from some form of electrical trace heating. DESIGN ISSUES 
Your products may be sited in flame proof areas, in locations below freezing point, or high ambient
temperature locations. It makes no difference to our designers as the products available in the field
of surface heating can cope with all these situations.
There are many types of trace heating tapes and cables available on the market ranging from self regulating heater tapes whose outputs vary dependent on the temperature of the product being heated, parallel circuitry heater tapes which are fixed wattage regardless of the length and basically comprise a new circuit every one metre, heating cables constructed from copper, cupro nickel or stainless steel which cope with high temperature work in dangerous environments and corrosive environments etc series parallel circuitry heater tapes constructed from glass, fibre glass, mica etc. Our designers at Peter Evans 'Bolton' Limited understand the different properties of all these options. Armed with all this knowledge and experience, we can offer our clients carefully selected products and specifications to suit their requirements. Top 
RUNNING COSTS AND MAINTENANCE 
Electrical trace heating is basically a maintenance free concept as, with thermostat controls or the
use of self regulating heater tapes, no electrical energy is wasted and the electrical trace heating
only operates when the process calls for heat. Combined with efficient and carefully considered
thermal insulation, the running cost of electrical trace heating is very viable as many installations
do not require much of an electrical loading above a mere 30 watts per metre. For example, in the
case of frost protection for sprinkler installations, the average loading is approximately 10 watts
per metre.
In addition, when installations require modifications either extending, reducing or new tee off's installed, electrical trace heating is sufficiently flexible to allow the circuits to be extended or reduced without adversely affecting the capability of the installation. It is a common misaprehension that, where steam is generated on site, pipe-work and tanks etc can be surface heated by this method at no cost. In reality, due to the high maintenance cost of steam, this is not the case. The comparatively small running cost of controlled electrical surface heating with the obvious advantages of control, cleanliness and freedom from maintenance is a considerably superior method of surface heating than steam, with its inherent problems of escapes etc. Top
