Replacement Pump Head Series H3

The universal electric motor with remote electronic control of the rotor speed of the H3 Series (pump head) is designed for the repair replacement of such electric motors in modern combined gas boilers, installed in the UK after autumn 2015, with counterclockwise rotor rotation. The remote control of the rotor speed of the H3 electric motors is carried out using the PWM technology - a low-voltage signal coming from the boiler's electronic board, via a special control cable. This is a universal PWM technology, standardized for pumps used in boilers of all boiler manufacturers without any exception, which are sold on the British market, taking into account new regulations and energy saving requirements in the heating industry.

The H3 Series electric motor is designed to replace failed pump motors in many modern models of wall-mounted gas boilers that have been operated in the UK since 2010. In most cases, engineers servicing wall-mounted boilers recommend their clients do not completely change the pump assembly that has failed, but only change the pump electric motor to restore the boiler operation. And this has become common practice in the UK in recent years. This is done not only to reduce the cost of failed pump repair. The cost of a universal electric motor of the H3 Series is several times cheaper than a complete pump assembly for a wall-mounted boiler. But thanks to the simplicity of the process itself, the time to replace the universal electric motor of the H3 pump is several times less than the time to replace the entire pump in the boiler. The electrical connection when installing the H3 electric motor is made using two special cables, which are included in the kit, in a matter of seconds. The electric motor installation takes no more than 10-15 minutes, taking into account the removal of the old failed motor by unscrewing four bolts, disconnecting it from cables and completely installation of a new H3 Series motor, while replacing an entire pump in some boiler models can take several hours of specialist work.

To make the right choice, you need to know the pump brand that is installed in your boiler and you will see an arrow of rotor speed on the nameplate of this pump. If the rotation arrow indicates counterclockwise, then the H3 pump is the correct choice. You also need to know the head of your pump, which is measured in meters, and you can see this indicator on the electric motor nameplate in your boiler. The head is usually indicated in meters and corresponds to the numbers 4, 5, 6, 7 or 8 meters. In our catalogue you can find a model similar to the specifications of your boiler pump, and you could save at least £200 from your household budget if you take our advice.

 H3 Series electric motors do not require maintenance during the entire service life that confirms their high reliability, which is why we successfully offer our customers a 6-year warranty for this equipment.
