Temperature Maintenance from Cross Electrical

Many raw materials and products will only remain in a liquid state if they are kept above a specific temperature. Electric trace heating and thermal insulation isa system used to maintain or increase the temperature of vessels and pipes. This process can be used to protect pipes from freezing or to maintain process temperatures for piping that must transport substances that solidify at ambient temperatures.

Traceheating is an electrical heating element placed in physical contact along the length of a pipe. The pipe is then covered with thermal insulation to maintain the temperature and reduce any heat losses, so that the heat generated by the element then preserves the temperature of the pipe.
Electrical trace heating and thermal insulation provides the solution of maintaining the temperature of a product in a pipe or vessel ensuring that your process pipework and systems deliver your product to the point of delivery at the required temperature.

When subjected to low ambient temperatures, heat loss can cause the contents viscosity to increase. This can cause the material to harden or set within the pipework, either slowing down the process or causing problems to pumping equipment. For example, wax is a substance which starts to solidify below 70 °C, which is usually far above the temperature of the surrounding air. Therefore the pipeline must be provided with an external source of heat to prevent the pipe and the material inside it from cooling down.

Trace heating can also be done with steam, but this requires a source of steam and may be inconvenient to install and operate. By utilising the correct type of Heating Cable, Thermal Insulation and Temperature Control, process pipework will operate efficiently for many years.
From our range of XSSTC (mineral insulated heating cables) XSW, XSWE (single wire), XHP and self-regulating heating cables we can confidently Design and Install, Maintain and Supply heating systems ensuring  production never stops.

Temperature maintenance and trace heating in your holiday home

If you’re lucky enough to own a holiday home or string of holiday homes it is probable that with vacation season being over your properties are more than likely to see a reduction in the number of holiday makers, guests and visitors.

As the nights get darker and the weather and temperatures cool your holiday homes will require more regular maintenance with an absence of body heat from passing people, traffic and day-to-day activities.

While you are not present at your holiday home, you should put in place such a maintenance program to keep your property in good working  order not only to keep running costs down but to be sure that it is at its most efficient and attractive when holiday season begins again.

Taking consideration to risks will keep your property safe, secure and functioning when you are unlikely to be visiting or renting out.

Prepare for winter

As many of us have experienced over the winter months, when temperatures plunge there is a high likelihood of pipes freezing or bursting.

Such damage can not only be harmful to your home but also to your bank balance and if it happens at a time when your holiday home is unoccupied, it can mean the burst pipe can go unnoticed for weeks which can cause even further damage – damaged ceilings, water-soaked furniture and ruined electrical appliances can be the nasty consequences of such an eventuality.

Without taking the right precautions freezing temperatures are likely to damage the plumbing and pipe systems for your vacation property.


There are many ways that you can prevent burst water and heating pipes and leaks:

Switching on NOT off

One of the main causes of frozen pipes is turning off the central heating completely when your holiday home is empty. While this can seem a cost efficient solution in terms of saving energy and money while your holiday home isn’t occupied it can expose your home to the outside temperatures in addition to the exposure of irreparable damage being caused to burst pipes.

As one of the main causes of frozen pipes, switching off your central heating completely and preventing the continuous flow of water is not the solution. It is recommended to leave your heating on a low temperature to minimise such dangers particularly during the coldest months (aim between 7 and 15 degrees) and consider a timer.

Lagging

Hot water or heating pipe work contained in unheated areas such as lofts, cellars and basements or those within the walls of your holiday home will be more prone to freezing.  As pipes are often situated above the insulation you should ensure that they are lagged well with insulating foam coverings. The thinner the pipes, the thicker the insulation sleeves should be. Water tanks also need insulation too. If your pipes are located in a loft space, keep the loft door ajar to allow heat to circulate. 

Drip Drop

You will have noticed a reoccurring theme in the above two methods – flow. Keeping the fluid within your pipe work continuously flowing will prevent water from freezing and therefore bursting as it provides pressure relief.
Simply turning off a tap for the prolonged period that your holiday home is empty will not be enough to prevent freezing as with a lot of water already in your heating and hot water systems putting a stop to the flow will build up pressure. Allowing your taps to drip slightly will keep water flowing albeit extremely slowly.



Drain
Suddenly stopping a continuous flow for a long period is likely to cause problems. Ask yourself, where is the water already in the system going to go? If it is cold, it will freeze; pressure will build up and as a consequence – burst.

Consider getting a qualified plumber to drain down the water and central heating system which will remove any risks to freezing completely.  

Temperature maintenance/Trace heating

While lagging outside or under insulated pipes can seem like enough, it isn’t always which is when having a temperature maintenance or trace heating system fitted can lower the risks the freezing temperatures can pose.

Having a low voltage electrical cable with frost thermostats wrapped around your pipes beneath the lagging is an excellent prevention method.

Thermostatically controlled, the heating cables only ever energise when temperatures drop below a stipulated figure, acting to prevent the disastrous consequences of winter.

Never overheating, with extremely low running costs purchasing trace heating from Cross Electrical can bring investment benefits for many years to come and do not require drainage of your water systems or interrupt your current electrical supplies.  Find out more about our trace heating solutions here.

Insurance

Having the right type of holiday home insurance to cover every eventuality is key to protecting your holiday home.  By predicting and implementing such cover you will ensure that your property is not rendered worthless following any misfortunes.
