Coronavirus outbreak is spreading ever more day after day, causing significant worldwide business disruptions and restrictions within supply chains.

The TPFay team is monitoring the situation and working to maintain delivery continuity.

We are working with all our UK and International suppliers in order to assess potential negative impacts, taking into consideration their full supply chains.

Based on the public information disclosed by the national and international Health Authorities and taking into consideration the purchase orders already confirmed by TPFay Ltd, we currently have no major criticality to report.

We will keep monitoring the situation and we will put our best effort to avoid disruption to our supply chains in your interest, however TPFay Ltd shall not be deemed to be liable for any shortage due to Coronavirus outbreak, as it is a clear “force majeure” event out of our control.

We thank you in advance for your understanding and collaboration.

Kind Regards

New Phones

Time for a change…

We are updating our phone systems, starting the week commencing 9th September 2019.

We have made all the plans we can, we think we have covered all the bases; but as with many things there are many “unknown unknowns”

IF there are any issues, use email

WhatsApp 07926953456
or call us on backup 07926953456.

We will be ready to help you however you get in touch.

Repair or New?

Here at TPFay we are looking to save our customers time and money.

Therefore we offer a repair service for old obsolete or burnt out heating elements. If you need to replace an old immersion heater or formed element, in many cases we can repair or rebuild your old heating element offering you considerable savings.

If you are looking for a repair or replacement please contact us for more information.

We always look to see if we can repair heaters, we do not like to waste materials or resources. Re-use is a valuable saving, in financial and environmental considerations, in some instances.

However, the construction of some existing heaters do not match our design and assembly criteria.

In these instances we use our judgement to determine, if repair of the existing heater is possible but may carry a great deal of risk of failure in service and during manufacture / repair process.

A contingency cost may be required to cover such risk.

The risk, combined with the time and resource required to attempt any repair, may be much greater than the material cost to manufacture a new heater, at this point we will offer the best alternative or replacement design.

Farewell to Brian

After over 27 years Brian Mitchinson has decided to retire from TPFay Ltd. Joining us when we only numbered 3 including the 2 directors. Brian has been an integral part of the DNA of this company.

We have made some tremendous changes in the intervening years, Most have been positive, and some were less so, but we all survived and continually learned and improved, though it all Brain was a steady and constant presence.

Brian would comment frequently on the “Time Machine” feeling of working here. It always seemed like five minutes since he started, but years had passed.

Now he has reached the time when he would like to stop. With the minimum of fuss and fanfare he has gone.

We wish him well and hope he enjoys his 7 day weekend.

Thank you Brian, we will miss you.

BSP Thread Sizes – A constant source of frustration for our customers

Brass Heads for Industrial Immersion Heaters

Industrial Immersion Heater Brass Screw Plug Head Components in various BSP Sizes from (¾”) 0.75″ to (2½”) 2.5″

It should be simple.

You measure something, and that is the size.


Not if you are measuring a thread, especially if it is a B.S.P. (Bristish Standard Pipe) thread……The size was originally based on the inner diameter measured in inches of a steel tube for which the thread was intended. This often causes confusion, as people think the size refers to the outside diameter of the male thread.

For example, the most common BSP Size for UK Immersion Heaters is 2¼” BSP.
However, if you measure roughly across the threads to check the diameter, it looks closer to 2½”, 2.58″ or 65.71mm, to be precise. But, how can you be precise when you have just struggled to remove an old immersion heater and you might be using a tape measure to try to gauge the thread?

If you ask for a 2½” BSP immersion heater to be made, it will arrive with a thread size of almost 2.96″ or 75.18mm, which will be really annoying as there is no way it will fit, it will be the thread size you asked for but not the size you need. It is the same for all other BSP threads so caution is required.

We at TPFay will try our best to guide you when you ask for a particular BSP size on a heater you would like us to make for you. We may seem to ask you to check the size you need, to the point of annoyance, but we are trying to guide you. We have encountered so many customers who have unwittingly ordered an immersion heater with the wrong size, it can be an expensive and frustrating experience.

Below is a table of common BSP sizes we use for TPFay Immersion Heaters and Element Fittings. Because we use it all the time it is simple for us, but we know it is less than straightforward if you are unfamiliar with the sizes, so was have a handy tip to help you identify the thread size you need if you are trying to measure around a male thread, it is almost impossible with a tape or desk rule.

  1. Cut a strip of paper that you can wrap around the thread you want to measure.
  2. Draw a Line across it with a pen or pencil.
  3. Wrap the paper strip once around the thread and make a second mark where the paper overlaps the first mark.
  4. Unwrap the paper and measure the distance between the marks. This should correspond to one of the measurements on C=Circumference (C)  mm  above.

If you have any difficulty, give us a call 03703 505058.
