Potterton Netaheat:

6/10, 10/16, 16/22, MkI, MkIIF, Electronic

If your Potterton Netaheat has failed, I have a van filled with parts and can generally fix them in a single visit. No matter what you may have been told by other firms, they CAN be mended - give me a try. I particularly enjoy fixing the really good boilers built from 20 to 35 years ago of which the Netaheat is a good example. I’ll need to run through a couple of things with you on the phone about the nature of failure, then provided you are within reasonable driving distance of me (I’m near Hungerford, west Berkshire) I can usually offer a repair on a ‘no fix, no fee” basis. Call or text me on 07866 766364 for details.

I also have a website covering the Netaheat specifically in more detail www.netaheat-repairs.co.uk

Things to do before calling someone, if your Netaheat has failed:

1) Make sure your heating is turned ON at the programmer, and in particular the room thermostat is turned up high. I get the occasional breakdown call-out (especially in autumn) where all I have to do is find the room thermostat and turn it UP. There is not much else I can suggest you try unless you have a ‘Profile’ version Netaheat, in which case try 2 below.

2) find and press the ‘reset’ button underneath. This only applies to the Netaheat Profile, the version shown here on the right. 

2) The pilot light. I mention this because people try to find a way to light it, but none of the Netaheats has a permanent pilot light. The boiler lights it’s own pilot light every time it starts so there is nothing the user can do to light it manually. Short video here.

3) Should you decide to call me, I will ask you which version Netaheat you have - MkIIF, Electronic or Profile (its marked on the front), which size you have - 6/10, 10/16 or 16/22 (also marked on the front), and a couple of questions about whether it sounds the same as normal but won’t light, and if you can see a spark or little flame through the viewing window. Answers will help me arrive at a provisional diagnosis on the phone.  

The faults I regularly encounter on Netaheats tend to centre around the following:

Fan failure

Control board faults (in a number of different ways)

Air pressure switch failure including blocked hose restrictor

Pilot light failure including partially blocked jet 

Ignition electrode failure

Gas valve solenoid open circuit

Mercury vapour switch failing to operate

Thermostat failure

Overheat tripping (Profile version only)

I’m happy to give technical help by email or text to anyone interested in diagnosing/fixing a Netaheat, but bear in mind the law requires anyone working on gas appliance to be competent, and if receiving payment for the work, Gas Safe Registered.

So if your Netaheat is within driving distance of me near Hungerford, west, Berkshire, I’m happy to make the trip. Bear in mind the more time spent driving the higher the cost is likely to be. A repair will still be far cheaper than a new boiler though, and you get the heat back on in just a day or two with none of the delay and disruption associated with fitting a new boiler.
