Electric Underfloor Heating

Solar PV Repair & Maintenance
Even though solar PV systems are generally very reliable sometimes things do go wrong. If your system stops generating energy or doesn't seem to be generating as much as it used to, one of our expert engineers can come and assess system, identify the problem and resolve any issue quickly and efficiently to ensure that your Solar PV System is back to full working order as quickly as possible. All of our call outs include up to 1 hour of labour and often we can resolve any problems within this period.
Common issues with Solar PV systems:
  • Faulty parts including inverters
  • Damage by pests such as pigeons
  • Storm damage
  • Reduction in electricity generation
  • Loose electrical connections
Solar ThermalSometimes, regardless of the care you take, things can go wrong with your solar thermal system. In these situations you can get in touch with us knowing that, with our local offices in the South East and our wealth of experience and knowledge of solar thermal hot water systems we will be able to get to you quickly to locate the problem and resolve it so that your system is back up and running as swiftly as possible.
Common problems we deal with:
  • Faulty pumps
  • Control unit and sensors failing
  • Air locks / blockages with the pipework
  • Leaking components (pipework, expansion vessels)
  • Leaking hot water cylinders
  • Storm damage

Electric Underfloor Heating
Rayotec Ltd has a range of underfloor heating kits suitable for under tiles, carpet, wood, vinyl and amtico floor coverings. The friendly team at Rayotec will advise you throughout your project answering any technical queries and tell you exactly which underfloor heating system is best for you.

The Rayotec systems are extremely competitively priced and if you order before 1pm, orders will be with you next working day.

Whether you are doing a refurbishment, renovation, extension or new build, electric underfloor heating is an effective solution to heat your home. Running costs are also kept to a minimum by the element being installed directly under the flooring and with the digital programmable thermostat provided, the system will only switch on when the room is calling for heat.

I was very impressed with Rayotec which I found on Google. I suspected I needed a new inverter for my solar panels. First contact suggested a call out to assess the problem. Their engineer came out on time and was very polite and friendly. It was established that the invert was in fact faulty . Inverter ordered and fitted in quick time 4 days later at a good price. I was able to pay for my purchase over the phone to yet again a polite friendly young lady. Paperwork and photos came back to me in quick time. I would certainly recommend Rayotec and would have no problem using the again.

Ordered an under floor heating kit with insulation boards from Rayotec, as they were highly recommended to us. Ordering was easy, and when we needed to swap some items, the service from Stephen was excellent. All-in-all, Rayotec is very high quality and the service is very efficient, would highly recommend.

My generation meter on the solar panels stopped working but I managed to contact Rayotec during 'lockdown' They made an appointment for an engineer to call and a week before the date he rang to say he had had a cancellation and could he come round in an hour. Two hours later he had found the (expensive) answer to the problem and fitted a new invertor. He was very careful and well aware of distancing and wore a mask. I would definitely recommend this firm to anyone needing this sort of help.
